　　UIButton的用处特别多，这里只记录下把按钮应用在图文显示的场景，和需要把图片作为按钮的背景图片显示场景；

另外记录下在父控件的子控件优先显示方法（控件置于最前面和置于最后面）。

先上效果图：

 

1、当在某个地方既需要显示图片，还需要显示文字，另外还要有点击功能的时候，这时按钮是个很好的选择。

　　按钮中的图片和文字的距离可以自由调整，图片的也可以上下左右翻转。日常项目中像这些场景都是很容易碰到的。

　　按钮图文设置、图文位置移动、按钮中图片翻转示例代码：

class="code_img_closed" src="/Upload/Images/2016101905/0015B68B3C38AA5B.gif" alt=""> 
/** 测试图文并茂的按钮，图文移动 */
- (void)addMoveImgAndTextButton{
    //1、创建一个按钮：30x50
    UIButton *iconBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 100, 150, 80)];
    [iconBtn setTitle:@"我的好友" forState:UIControlStateNormal];
    [iconBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [iconBtn setImage:[UIImage imageNamed:@"pointer"] forState:UIControlStateNormal];
    iconBtn.layer.borderColor = [UIColor redColor].CGColor;  //边框颜色
    iconBtn.layer.borderWidth = 1;  //边框宽度
    iconBtn.titleLabel.backgroundColor = [UIColor greenColor]; //文字颜色
    iconBtn.imageView.backgroundColor = [UIColor blackColor]; //图片颜色
    [iconBtn addTarget:self action:@selector(clickButton:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:iconBtn];
    self.iconBtn = iconBtn;
    
    //2、移动iconBtn按钮图片和文字
    UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(170, 100, 120, 45)];
    [btn setTitle:@"图右移字左移" forState:UIControlStateNormal];
    btn.titleLabel.numberOfLines = 0;
    [btn setBackgroundColor:[UIColor blackColor]];
    [btn addTarget:self action:@selector(changeBtnFrame:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
    
    //3、移动iconBtn按钮图片和文字
    UIButton *btn2 = [[UIButton alloc] initWithFrame:CGRectMake(170, 150, 120, 45)];
    [btn2 setTitle:@"字右移图左移" forState:UIControlStateNormal];
    btn2.titleLabel.numberOfLines = 0;
    [btn2 setBackgroundColor:[UIColor blackColor]];
    [btn2 addTarget:self action:@selector(changeBtnFrame2:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn2];
    
    //分割线
    UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, 210, 500, 1)];
    lineView.backgroundColor = [UIColor grayColor];
    [self.view addSubview:lineView];
}

/** 点击按钮使图片位置翻转 */
- (void)clickButton:(UIButton *)sender{
    sender.imageView.transform = CGAffineTransformRotate(sender.imageView.transform, M_PI);
}

/** 移动图片和文字位置 */
- (void)changeBtnFrame:(UIButton *)sender{
    
    UIEdgeInsets edge = self.iconBtn.imageEdgeInsets;
    CGFloat changeNum = 10;
    self.iconBtn.imageEdgeInsets = UIEdgeInsetsMake(0, edge.left + changeNum, 0, -(edge.left + changeNum));
    self.iconBtn.titleEdgeInsets = UIEdgeInsetsMake(0, -(edge.left + changeNum), 0, edge.left + changeNum);
    
    NSLog(@"edge.left: %f, edge.right: %f", edge.left, edge.right);

/** 反方向移动图片和文字位置 */

    UIEdgeInsets edge = self.iconBtn.imageEdgeInsets;
    CGFloat changeNum = 10;
    self.iconBtn.imageEdgeInsets = UIEdgeInsetsMake(0, edge.left - changeNum, 0, -(edge.left - changeNum));

2、有时候需要给按钮设置背景图片，一般UI给个图片，然后我们自己对图片进行处理，让背景图片自适应按钮展示，矩形圆角。

　　但是有时候，产品要求显示的按钮左右必须是圆形的，这时候虽然可以让ui切个适配的图片做背景，其实针对如果是背景图片是纯色的话，我们可以利用

控件的layer.masksToBounds， 和layer.cornerRadius属性来让按钮或者其他控件左右两边都是圆形的。

下面写了五个橙色背景的按钮作比较：背景图片和按钮尺寸匹配的、背景图片和按钮尺寸或偏大或偏小的、处理背景图片让背景图片自适应按钮的、不用背景图片使用图层来设置按钮左右圆形的：

/** 测试给按钮设置背景图片 */
- (void)addBackgroundImgButton{
    //4、96x25 按钮设置背景图片，颜色rgb(255,145,0)
    UIImage *img = [UIImage imageNamed:@"btn_bg"];
    UIButton *clickBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 240, 96, 25)];
    [clickBtn setBackgroundImage:img forState:UIControlStateNormal];
    [clickBtn setTitle:@"click Me" forState:UIControlStateNormal];
    [self.view addSubview:clickBtn];
    
    //4.2 给按钮设置背景图片, 按钮图片不适配
    UIButton *clickBtn2 = [[UIButton alloc] initWithFrame:CGRectMake(120, 220, 120, 50)];
    [clickBtn2 setBackgroundImage:img forState:UIControlStateNormal];
    [clickBtn2 setTitle:@"click Me" forState:UIControlStateNormal];
    [self.view addSubview:clickBtn2];
    
    //4.3 给按钮设置背景图片，按钮和图片不适配
    UIButton *clickBtn3 = [[UIButton alloc] initWithFrame:CGRectMake(260, 240, 80, 15)];
    [clickBtn3 setBackgroundImage:img forState:UIControlStateNormal];
    [clickBtn3 setTitle:@"click Me" forState:UIControlStateNormal];
    [self.view addSubview:clickBtn3];
    
    //4.4 处理背景图片，让背景图片自适应按钮
    NSLog(@"img.size: %@", NSStringFromCGSize(img.size));
    UIImage *newImg = [img stretchableImageWithLeftCapWidth:img.size.width/2 topCapHeight:img.size.height/2];
    NSLog(@"newImg.size: %@", NSStringFromCGSize(newImg.size));
    UIButton *clickBtn4 = [[UIButton alloc] initWithFrame:CGRectMake(10, 300, 150, 60)];
    [clickBtn4 setBackgroundImage:newImg forState:UIControlStateNormal];
    [clickBtn4 setTitle:@"click Me" forState:UIControlStateNormal];
    [self.view addSubview:clickBtn4];
    
    //4.5 按钮不使用背景图片，设置背景颜色当做有背景图片
    UIButton *clickBtn5 = [[UIButton alloc] initWithFrame:CGRectMake(180, 300, 150, 60)];
    [clickBtn5 setTitle:@"click Me" forState:UIControlStateNormal];
    clickBtn5.layer.masksToBounds = YES;
    clickBtn5.layer.cornerRadius = 30;
    clickBtn5.backgroundColor = [UIColor colorWithRed:255/255.f green:145/255.f blue:0 alpha:1];
    [self.view addSubview:clickBtn5];
    
    //分割线
    UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, 380, 500, 1)];
    lineView.backgroundColor = [UIColor grayColor];
    [self.view addSubview:lineView];
}

3、在有些场景下，需要控制控件的优先显示或者置后显示，需要用到方法

- (void)bringSubviewToFront:(UIView *)view;  // 将子控件view显示在父控件的所有子控件的最前面

- (void)sendSubviewToBack:(UIView *)view;  //将子控件view显示在父控件的所有子控件的最后面

示例代码：

/** 测试子控件的优先显示（置前和置后） */
- (void)testSubControlShowFront{
    //1、红色view
    UIView *redView = [[UIView alloc] initWithFrame:CGRectMake(10, 420, 200, 200)];
    redView.backgroundColor = [UIColor redColor];
    redView.tag = 11;
    [self.view addSubview:redView];
    
    //2、黑色view
    UIView *blackView = [[UIView alloc] initWithFrame:CGRectMake(30, 400, 200, 200)];
    blackView.backgroundColor = [UIColor blackColor];
    blackView.tag = 12;
    [self.view addSubview:blackView];
    
    //3、紫色view
    UIView *purpleView = [[UIView alloc] initWithFrame:CGRectMake(50, 440, 200, 200)];
    purpleView.backgroundColor = [UIColor purpleColor];
    purpleView.tag = 13;
    [self.view addSubview:purpleView];
    
    //添加操作按钮
    UIButton *operatorBtn = [[UIButton alloc] initWithFrame:CGRectMake(280, 400, 100, 30)];
    [operatorBtn setTitle:@"红色置前" forState:UIControlStateNormal];
    operatorBtn.tag = 1;
    operatorBtn.backgroundColor = [UIColor blackColor];
    [operatorBtn addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:operatorBtn];
    
    UIButton *operatorBtn2 = [[UIButton alloc] initWithFrame:CGRectMake(280, 450, 100, 30)];
    [operatorBtn2 setTitle:@"黑色置前" forState:UIControlStateNormal];
    operatorBtn2.tag = 2;
    operatorBtn2.backgroundColor = [UIColor blackColor];
    [operatorBtn2 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:operatorBtn2];
    
    UIButton *operatorBtn3 = [[UIButton alloc] initWithFrame:CGRectMake(280, 500, 100, 30)];
    [operatorBtn3 setTitle:@"紫色置前" forState:UIControlStateNormal];
    operatorBtn3.tag = 3;
    operatorBtn3.backgroundColor = [UIColor blackColor];
    [operatorBtn3 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:operatorBtn3];
    
    UIButton *operatorBtn4 = [[UIButton alloc] initWithFrame:CGRectMake(280, 550, 100, 30)];
    [operatorBtn4 setTitle:@"紫色置后" forState:UIControlStateNormal];
    operatorBtn4.tag = 4;
    operatorBtn4.backgroundColor = [UIColor redColor];
    [operatorBtn4 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:operatorBtn4];
}
/** 操作按钮，切换view置前显示 */
- (void)changeViewToFrontShow:(UIButton *)sender{
    
    if (sender.tag == 1){
        //红色置前
        UIView *redView = [self.view viewWithTag:11];
        
        //将子控件redView在父控件view的所有子控件的最前面显示
        [self.view bringSubviewToFront:redView];
    }
    else if (sender.tag == 2){
        //黑色置前
        UIView *blackView = [self.view viewWithTag:12]; //获取黑色子控件
        
        //将子控件blackView在父控件view的所有子控件的最前面显示
        [self.view bringSubviewToFront:blackView];
        
    }
    else if (sender.tag == 3){
        //紫色置前
        UIView *purpleView = [self.view viewWithTag:13]; //获取紫色子控件
        
        //将子控件purpleView在父控件view的所有子控件的最前面显示
        [self.view bringSubviewToFront:purpleView];
    }
    else if (sender.tag == 4){
        //紫色置后
        UIView *purpleView = [self.view viewWithTag:13]; //获取紫色子控件
        
        //将子控件purpleView在父控件view的所有子控件的最后面显示
        [self.view sendSubviewToBack:purpleView];
    }
