准备工作---原文来自这个

首先要在微信开放平台申请 AppID（我第一天晚上申请的，第二天中午就通过了），接着导入 SDK，也就是3个 .h 和一个 .a 文件，详情见这里

如果你是 copy 在自建 group 里面，

1.需要在 Build Phases - Link Binary With Libraries 里面 .a 文件

2.在 Copy Bundle Resources add .h 文件

3.在 Bulid Settings - Library Search Paths "+" sdk 路径

如果 copy 在自带 group 里面，则不需要，已经自动配置好

AppDelegate.h ,import "WXApi.h" 和 遵守协议

#import <UIKit/UIKit.h>
#import "WXApi.h"

@interface AppDelegate : UIResponder <UIApplicationDelegate,WXApiDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //申请的 AppID
    [WXApi registerApp:@"wxxxxx"];
    return YES;
}
//重写 handleOpenURL
-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
    return [WXApi handleOpenURL:url delegate:self];
}
//重写 openURL
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{
    return [WXApi handleOpenURL:url delegate:self];
}

在你需要引用的类里面

#import "ViewController.h"
#import "WXApi.h"

@interface ViewController ()
@property (nonatomic,strong)UIButton *button;
@end

@implementation ViewController
static NSString *KLinkURL = @"http://www.iqiyi.com/a_19rrhbkfv1.html?vfm=2008_aldbd";
static NSString *KLinkTagName = @"WECHAT_TAG_JUMP_SHOWRANK";
static NSString *KLinkTitle = @"史上最帅男人";
static NSString *KLinkDescription = @"妈呀，谁都别拦我，我要嫁给他！！！！！！！！";

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.view addSubview:self.button];
}

-(void)Click{

    //创建发送对象实例
    SendMessageToWXReq *sendReq = [[SendMessageToWXReq alloc] init];
    sendReq.bText = NO;//不使用文本信息
    sendReq.scene = 0;//0 = 好友列表 1 = 朋友圈 2 = 收藏
    
    //创建分享内容对象
    WXMediaMessage *urlMessage = [WXMediaMessage message];
    urlMessage.title = KLinkTitle;//分享标题
    urlMessage.description = KLinkDescription;//分享描述
 
    [urlMessage setThumbImage:[UIImage imageNamed:@"sb2.jpg"]];//分享图片,使用SDK的setThumbImage方法可压缩图片大小,图片大小不能超过 32 KB
    
    //创建多媒体对象
    WXWebpageObject *webObj = [WXWebpageObject object];
    webObj.webpageUrl = KLinkURL;//分享链接
    
    //完成发送对象实例
    urlMessage.mediaObject = webObj;
    sendReq.message = urlMessage;
    
    //发送分享信息
    [WXApi sendReq:sendReq];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

-(UIButton *)button{
    if (!_button) {
        _button = [[UIButton alloc]init];
        _button.frame = CGRectMake(100, 100, 100, 100);
        _button.backgroundColor = [UIColor redColor];
        [_button addTarget:self action:@selector(Click) forControlEvents:UIControlEventTouchUpInside];
    }
    return _button;
}
