iOS开发之常用第三方框架(下载地址,使用方法,总结)
说句实话,自学了这么久iOS,如果说我不知道的但是又基本上都摸遍了iOS相关知识,但是每次做项目的时候,遇到难一点的地方或者没试过的东西就闷了。
比如这次,打算做一个着手做一个iOS的项目,是一个关于日计划的小软件,界面都其他的都算满意,网络就不说了,没有服务器,所以很多数据相关的功能不无法实现。
但是嘴头疼的事情就是,比如遇到一个功能的时候,其实如果说要实现的话还是可以的,但是每次在我实现之后我总会想到,这么实现更好,这么实现更简单,更加优化,虽然这么实现能够让我学到东西。
做完之后看了别人的相似代码才会知道原来第三方框架原来这么简单这么容易,而且代码这么少,我又换成第三方的框架来实现。
换来换去,换了一大堆,没办法只能这里找点哪里找点,搞了一天终于都弄完了。
现在我就总结一下第三方的框架,虽然大部分都是在别人那里搬过来的,但是笔者做了小量的优化更改还有就是增加一了一下最新的。
当然这里只是一些常用的别人总结过了的ios开发OC版的第三方,关于Swift的第三方现在不是很多,也没有太多很好的,再后面的文章我将会试着总结一下关于Swift的第三方框架的使用和总结,希望各位不要吐槽,也希望能对大家有用!
break-word; color: #ff9900;">一:Reachability 检测网络连接
用来检查网络连接是否可用:包括WIFI和WWAN(3G/EDGE/CDMA等)两种工作模式。
可以从Apple网站下载到:http://developer.apple.com/library/ios/#samplecode/Reachability/History/History.html#//apple_ref/doc/uid/DTS40007324-RevisionHistory-DontLinkElementID_1。
现在有更好的替代品:https://github.com/tonymillion/Reachability,比Apple提供的兼容性更好,而且更加好用,更具体的使用方法请看它提供的例子。
- <font color="rgb(51, 51, 51)">Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];
-
reach.reachableBlock = ^(Reachability*reach) {
-
NSLog(@"网络可用!");
-
};
-
reach.unreachableBlock = ^(Reachability*reach) {
-
NSLog(@"网络不可用!");
-
};
-
// 开始监听
-
[reach startNotifier];</font>
二:ASIHTTPRequest
网络请求ASIHTTPRequest是对CFNetwork API的一个包装,它提供了一套更加简洁的API,使用起来也更加简单,但是现在已经没有再继续更新了,所以如果你是要用发送网络请求的话我们后面还有更好的AFN框架,但是这个了解就可以了。
官方网站:http://allseeing-i.com/ASIHTTPRequest/
GitHub:https://github.com/pokeb/asi-http-request
它不仅仅支持基本的HTTP请求,而且支持基于REST的服务(GET/POST/PUT/DELETE)。最让人喜欢的是,它支持block语法:
-
NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
-
__block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
-
[request setCompletionBlock:^{
-
// Use when fetching text data
-
NSString *responseString = [request responseString];
-
-
// Use when fetching binary data
-
NSData *responseData = [request responseData];
-
}];
-
[request setFailedBlock:^{
-
NSError *error = [request error];
-
}];
-
[request startAsynchronous];
它的ASIFormDataRequest子类可以横容易的提交表单数据和文件:
-
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
-
[request setPostValue:@"Ben" forKey:@"first_name"];
-
[request setPostValue:@"Copsey" forKey:@"last_name"];
-
// Upload a file on disk
-
[request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"
-
forKey:@"photo"];
-
// Upload an NSData instance
-
[request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];
复制代码
详细的使用方法请下载相应的源代码及例子,或者从官方的使用说明http://allseeing-i.com/ASIHTTPRequest/How-to-use开始。
三:MBProgressHUD
提示效果支持各种状态加载的提示效果,以及带进度的提示效果。
GitHub:https://github.com/matej/MBProgressHUD
一般会在.m文件实现MBProgressHUDDelegate协议,并声明HUD变量:
-
@interface SampleViewController ()<MBProgressHUDDelegate>
-
{
-
MBProgressHUD *HUD;
-
}
-
#pragma mark -
-
#pragma mark MBProgressHUDDelegate methods
-
-
- (void)hudWasHidden:(MBProgressHUD *)hud {
-
// Remove HUD from screen when the HUD was hidded
-
[HUD removeFromSuperview];
-
HUD = nil;
-
}
在执行某个异步请求时开始调用:
-
HUD = [MBProgressHUD showHUDAddedTo:self.webView animated:YES];
-
HUD.labelText = @"正在请求...";
-
// mode参数可以控制显示的模式
-
//HUD.mode = MBProgressHUDModeText;
-
HUD.delegate = self;
请求完成时隐藏提示效果:
-
[HUD hide:YES];
对于同步方法一般都是用showWhileExecuting方法,方法执行完成之后会自动隐藏提示效果:
-
[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];
四:SVProgressHUD
提示效果
GitHub:https://github.com/samvermette/SVProgressHUD
SVProgressHUD和MBProgressHUD效果差不多,不过不需要使用协议,同时也不需要声明实例。直接通过类方法进行调用即可:
-
[SVProgressHUD method]
可以使用以下方法来显示状态:
-
+ (void)show;
-
+ (void)showWithMaskType:(SVProgressHUDMaskType)maskType;
-
+ (void)showWithStatus:(NSString*)string;
-
+ (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;
如果需要明确的进度,则使用以下方法:
-
+ (void)showProgress:(CGFloat)progress;
-
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;
-
+ (void)showProgress:(CGFloat)progress status:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;
通过dismiss方法来隐藏提示:
-
+ (void)dismiss;
另外提供了以下方法用于显示状态,并在1秒后自动隐藏提示(使用的图标来源于Glyphish:http://www.glyphish.com/):
-
+ (void)showSuccessWithStatus:(NSString*)string;
-
+ (void)showErrorWithStatus:(NSString *)string;
-
+ (void)showImage:(UIImage*)image status:(NSString*)string; // use 28x28 white pngs
五:ZAActivityBar
提示效果
GitHub:https://github.com/zacaltman/ZAActivityBar
ZAActivityBar和SVProgressHUD非常相似,它提供了更加简洁的API来显示提示效果。ZAActivityBar使用的动画效果来源于ZKBounceAnimation(https://github.com/khanlou/SKBounceAnimation),成功、失败的状态图标来源于Pictos(http://pictos.cc/)。显示加载状态:
-
[ZAActivityBar showWithStatus:@"加载中..."];
显示成功、失败状态:
-
[ZAActivityBar showSuccessWithStatus:@"成功!"];
-
[ZAActivityBar showErrorWithStatus:@"失败!"];
隐藏提示:
-
[ZAActivityBar dismiss];
六:SBJson
JSON解析官方: http://sbjson.org/
GitHub:https://github.com/stig/json-framework
API使用起来稍显繁琐,特别是初始化的时候:
-
@interface TestViewController ()<SBJsonStreamParserAdapterDelegate> {
-
SBJsonStreamParser *parser;
-
SBJsonStreamParserAdapter *adapter;
-
}
-
-
// 冗长的初始化方法足以吓到一大片人
-
- (void)initSBJSON
-
{
-
// We don't want *all* the individual messages from the
-
// SBJsonStreamParser, just the top-level objects. The stream
-
// parser adapter exists for this purpose.
-
adapter = [[SBJsonStreamParserAdapter alloc] init];
-
-
// Set ourselves as the delegate, so we receive the messages
-
// from the adapter.
-
adapter.delegate = self;
-
-
// Create a new stream parser..
-
parser = [[SBJsonStreamParser alloc] init];
-
-
// .. and set our adapter as its delegate.
-
parser.delegate = adapter;
-
-
// Normally it's an error if JSON is followed by anything but
-
// whitespace. Setting this means that the parser will be
-
// expecting the stream to contain multiple whitespace-separated
-
// JSON documents.
-
parser.supportMultipleDocuments = YES;
-
}
-
-
#pragma mark SBJsonStreamParserAdapterDelegate methods
-
-
- (void)parser:(SBJsonStreamParser *)parser foundArray:(NSArray *)array {
-
[NSException raise:@"unexpected" format:@"Should not get here"];
-
}
-
-
- (void)parser:(SBJsonStreamParser *)parser foundObject:(NSDictionary *)dict {
-
NSLog(@"SBJson parser foundObject");
-
// 处理返回的数据
-
}
-
-
// 使用ASIHTTPRequest请求测试
-
- (void) loadData {
-
__block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
-
[request setRequestMethod:@"POST"];
-
[request setCompletionBlock:^{
-
// Use when fetching text data
-
//NSString *responseString = [request responseString];
-
// Use when fetching binary data
-
NSData *responseData = [request responseData];
-
NSLog(@"Connection didReceiveData of length: %u", responseData.length);
-
-
// Parse the new chunk of data. The parser will append it to
-
// its internal buffer, then parse from where it left off in
-
// the last chunk.
-
SBJsonStreamParserStatus status = [parser parse:responseData];
-
-
if (status == SBJsonStreamParserError) {
-
NSLog(@"Parser error: %@", parser.error);
-
} else if (status == SBJsonStreamParserWaitingForData) {
-
NSLog(@"Parser waiting for more data");
-
}
-
}];
-
[request setFailedBlock:^{
-
NSError *error = [request error];
-
NSLog(@"failed - %@ %@", [error localizedDescription], error);
-
}];
-
[request startAsynchronous];
-
}
七:JSONKit
JSON解析
GitHub:https://github.com/johnezang/JSONKit
提供比SBJson更优异的性能以及更加简便的使用方法,但是中文最好使用utf-8格式(\uXXXX),否则容易造成乱码。API调用起来非常简单,省去了SBJson那么一大堆的方法:
-
JSONDecoder* decoder = [[JSONDecoder alloc] initWithParseOptions:JKParseOptionNone];
-
id result = [decoder objectWithData:jsonData];
详细的使用方法请看它的GitHub主页。
八:SDWebImage
图片异步加载及缓存
SDWebImage用于异步下载网络上的图片,并支持对图片的缓存等。多数情况下是使用UIImageView+WebCache为UIImageView异步加载图片:
-
#import <SDWebImage/UIImageView+WebCache.h>
-
// ...
-
[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
-
placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
需要注意的是,pladeholderImage的大小一定要大于UIImageView的大小,否则可能不显示placeholderImage图片。它还支持block语法用于在加载完成时做一些操作:
-
[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
-
placeholderImage:[UIImage imageNamed:@"placeholder.png"]
-
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {... completion code here ...}];
SDWebImage并不局限于UIImageView上,使用SDWebImageManager完成更多的操作:
-
SDWebImageManager *manager = [SDWebImageManager sharedManager];
-
[manager downloadWithURL:imageURL
-
options:0
-
progress:^(NSUInteger receivedSize, long long expectedSize)
-
{
-
// 下载进度
-
}
-
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType)
-
{
-
if (image)
-
{
-
// 下载完成
-
}
-
}];
或者使用Image Downloader也是一样的效果:
-
[SDWebImageDownloader.sharedDownloader downloadImageWithURL:imageURL
-
options:0
-
progress:^(NSUInteger receivedSize, long long expectedSize)
-
{
-
// 进度
-
}
-
completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished)
-
{
-
if (image && finished)
-
{
-
// 下载完成
-
}
-
}];
九:UIActivityIndicator-for-SDWebImage
为SDWebImage显示加载效果
GitHub:https://github.com/JJSaccolo/UIActivityIndicator-for-SDWebImage
用于为SDWebImage在UIImageView加载图片时,显示加载效果(UIActivityIndicatorView实现),它提供以下方法:
-
- (void)setImageWithURL:(NSURL *)url usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder options:(SDWebImageOptions)options
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url
completed:(SDWebImageCompletedBlock)completedBlock
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder completed:(SDWebImageCompletedBlock)completedBlock
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder options:(SDWebImageOptions)options
completed:(SDWebImageCompletedBlock)completedBlock
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder options:(SDWebImageOptions)options
progress:(SDWebImageDownloaderProgressBlock)progressBlock
completed:(SDWebImageCompletedBlock)completedBlock
usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
十:UIImage+Resize
调整图片大小
GitHub:https://github.com/coryalder/UIImage_Resize
提供多种方法为图片设置透明度、圆角、裁剪、调整大小等:
-
- (UIImage *)imageWithAlpha;
-
- (UIImage *)transparentBorderImage:(NSUInteger)borderSize;
-
- (UIImage *)roundedCornerImage:(NSInteger)cornerSize borderSize:(NSInteger)borderSize;
-
- (UIImage *)croppedImage:(CGRect)bounds;
-
- (UIImage *)thumbnailImage:(NSInteger)thumbnailSize
-
transparentBorder:(NSUInteger)borderSize
-
cornerRadius:(NSUInteger)cornerRadius
-
interpolationQuality:(CGInterpolationQuality)quality;
-
- (UIImage *)resizedImage:(CGSize)newSize
-
interpolationQuality:(CGInterpolationQuality)quality;
-
- (UIImage *)
-
resizedImageWithContentMode:(UIViewContentMode)contentMode
-
bounds:(CGSize)bounds
-
interpolationQuality:(CGInterpolationQuality)quality;
更详细使用见:http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/
十一:ImageCacheResize
异步加载图片、缓存及调整大小
GitHub:https://github.com/toptierlabs/ImageCacheResize
整合了SDWebImage和UIImage+Resize的功能,用于图片的异步加载、缓存、以及下载完成后调整大小并显示在UIImageView上。提供了以下API用于加载图片以及加载完成后调整图片大小:
-
- (void)setImageWithURL:(NSURL *)url andCropToBounds:(CGRect)bounds;
-
- (void)setImageWithURL:(NSURL *)url andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder andCropToBounds:(CGRect)bounds;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder
options:(SDWebImageOptions)options andResize:(CGSize)size;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder options:(SDWebImageOptions)options andResize:(CGSize)size
withContentMode:(UIViewContentMode)mode;
-
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage
*)placeholder
options:(SDWebImageOptions)options andCropToBounds:(CGRect)bounds;
使用方法和SDWebImage一样简单,如以下官方例子:
-
[imageview setImageWithURL:[NSURL
URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"]
andResize:CGSizeMake(30, 30)
withContentMode:UIViewContentModeScaleAspectFit]; // 按比例缩放
-
[imageview setImageWithURL:[NSURL
URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"]
andCropToBounds:CGRectMake(0, 0, 100, 100)]; // 裁剪成100x100大小
十二:EGOTableViewPullRefresh
下拉刷新
GitHub:https://github.com/enormego/EGOTableViewPullRefresh
这是最早出现的为UITableView提供下拉刷新功能的类库,使用起来稍显麻烦,需要实现诸多协议(代码取自官方DEMO):
-
#import "EGORefreshTableHeaderView.h"
-
-
@interface RootViewController :
UITableViewController <EGORefreshTableHeaderDelegate,
UITableViewDelegate, UITableViewDataSource>{
-
EGORefreshTableHeaderView *_refreshHeaderView;
-
// 是否正在加载中
-
BOOL _reloading;
-
}
-
-
- (void)viewDidLoad {
-
[super viewDidLoad];
-
-
if (_refreshHeaderView == nil) {
-
EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc]
initWithFrame:CGRectMake(0.0f, 0.0f -
self.tableView.bounds.size.height, self.view.frame.size.width,
self.tableView.bounds.size.height)];
-
view.delegate = self;
-
[self.tableView addSubview:view];
-
_refreshHeaderView = view;
-
[view release];
-
}
-
// 更新最后加载时间
-
[_refreshHeaderView refreshLastUpdatedDate];
-
}
-
-
#pragma mark -
-
#pragma mark Data Source Loading / Reloading Methods
-
-
- (void)reloadTableViewDataSource{
-
// 在这里加入代码用于获取数据
-
_reloading = YES;
-
}
-
-
- (void)doneLoadingTableViewData{
-
// 数据加载完成时调用这个方法
-
_reloading = NO;
-
[_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];
-
}
-
-
#pragma mark -
-
#pragma mark UIScrollViewDelegate Methods
-
-
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
-
[_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];
-
}
-
-
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
-
[_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];
-
}
-
-
#pragma mark -
-
#pragma mark EGORefreshTableHeaderDelegate Methods
-
-
- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{
-
[self reloadTableViewDataSource];
-
[self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0];
-
}
-
-
- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{
-
return _reloading; // should return if data source model is reloading
-
}
-
-
- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{
-
return [NSDate date]; // should return date data source was last changed
-
}
十三:PullToRefresh
下拉刷新
GitHub:https://github.com/leah/PullToRefresh
PullToRefresh提供比EGOTableViewPullRefresh更加简单的使用方法,只要继承自PullRefreshTableViewController,再实现refresh方法即可:
-
- (void)refresh {
-
// 加载数据
-
-
[self.tableView reloadData]; // 重新载入UITableView
-
[self stopLoading]; //停止动画
-
}
十四:STableViewController
下拉刷新、上拉加载更多
GitHub:https://github.com/shiki/STableViewController
STableViewController比PullToRefresh多了一个上拉加载更多功能,使用上也差不多简单,需要继承自STableViewController,再实现一些方法:
-
- (void) viewDidLoad
-
{
-
[super viewDidLoad];
-
-
self.title = @"STableViewController Demo";
-
[self.tableView setBackgroundColor:[UIColor lightGrayColor]];
-
-
// 需要创建两个自定义视图用于显示"下拉刷新"、"上拉加载更多"
-
self.headerView = headerView;
-
self.footerView = footerView;
-
}
-
-
#pragma mark - Pull to Refresh
-
- (void) pinHeaderView
-
{
-
[super pinHeaderView];
-
-
// 下拉刷新视图显示一些加载动画
-
}
-
- (void) unpinHeaderView
-
{
-
[super unpinHeaderView];
-
-
// 下拉刷新视图停止动画
-
}
-
- (void) headerViewDidScroll:(BOOL)willRefreshOnRelease scrollView:(UIScrollView *)scrollView
-
{
-
// 下拉刷新视图显示状态信息
-
if (willRefreshOnRelease)
-
//hv.title.text = @"松开后刷新...";
-
else
-
//hv.title.text = @"下拉刷新...";
-
}
-
-
- (BOOL) refresh
-
{
-
if (![super refresh])
-
return NO;
-
-
// 下拉刷新加载数据
-
[self performSelector:@selector(addItemsOnTop) withObject:nil afterDelay:2.0];
-
return YES;
-
}
-
-
#pragma mark - Load More
-
- (void) willBeginLoadingMore
-
{
-
// 上拉加载更多视图加载动画
-
}
-
- (void) loadMoreCompleted
-
{
-
[super loadMoreCompleted];
-
// 上拉加载更多视图停止动画
-
-
if (!self.canLoadMore) {
-
//没有更多数据的时候执行代码...
-
}
-
}
-
-
- (BOOL) loadMore
-
{
-
if (![super loadMore])
-
return NO;
-
-
// 上拉加载更多数据
-
[self performSelector:@selector(addItemsOnBottom) withObject:nil afterDelay:2.0];
-
return YES;
-
}
-
-
//
-
- (void) addItemsOnTop
-
{
-
// 加载数据...
-
-
[self.tableView reloadData];
-
// 数据加载完成通知上拉视图
-
[self refreshCompleted];
-
}
-
-
- (void) addItemsOnBottom
-
{
-
// 加载更多数据...
-
[self.tableView reloadData];
-
-
// 通过判断设置是否可以加载更多
-
//self.canLoadMore = NO;
-
// 数据加载完成通知下拉视图
-
[self loadMoreCompleted];
-
}
十五:SVPullToRefresh
下拉刷新、上拉加载更多
GitHub:https://github.com/samvermette/SVPullToRefresh
包含SVPullToRefresh + SVInfiniteScrolling为UITableView提供下拉刷新、上拉加载更多功能。使用起来也相当简单,只要在UITableViewController里实现以下方法:
-
- (void)viewDidLoad {
-
[super viewDidLoad];
-
-
__weak SVViewController *weakSelf = self;
-
-
// 设置下拉刷新
-
[self.tableView addPullToRefreshWithActionHandler:^{
-
[weakSelf insertRowAtTop];
-
}];
-
-
// 设置上拉加载更多
-
[self.tableView addInfiniteScrollingWithActionHandler:^{
-
[weakSelf insertRowAtBottom];
-
}];
-
}
-
-
- (void)viewDidAppear:(BOOL)animated {
-
[tableView triggerPullToRefresh];
-
}
-
-
- (void)insertRowAtTop {
-
// 获取数据....
-
-
// 停止动画
-
[self.tableView.pullToRefreshView stopAnimating];
-
}
-
-
- (void)insertRowAtBottom {
-
// 获取数据....
-
-
// 停止动画
-
[weakSelf.tableView.infiniteScrollingView stopAnimating];
-
}
十六:CMPopTipView
