iOS-自定义 UIButton-文字在左、图片在右（二）

    UIButton *button02 = [[UIButton alloc] init];
    button02.titleLabel.font = [UIFont systemFontOfSize:14];
    [button02 setTitle:@"地区" forState:UIControlStateNormal];
    UIImage *imageBtn02 = [UIImage imageNamed:@"YellowDownArrow"];
    [button02 setImage:imageBtn02 forState:UIControlStateNormal];
    [view addSubview:button02];
    // 设置 frame
    [button02 mas_makeConstraints:^(MASConstraintMaker *make) {
        make.centerY.equalTo(view);
        make.left.equalTo(view).offset(kScreenWidth / 8 * 3.5);
    }];
    // 如果用 Masnory 一定要调这句,不然约束有问题
    [button02 layoutIfNeeded];
    
    // 取出 titleLabel 的宽度
    CGFloat labelWidth02 = button02.titleLabel.bounds.size.width;
    // 取出 imageView 的宽度
    CGFloat imageWidth02 = button02.imageView.bounds.size.width;
    // 设置 titleLabel 的内边距
    button02.titleEdgeInsets = UIEdgeInsetsMake(0, -imageWidth02, 0, imageWidth02);
    // 设置 imageView 的内边距
    button02.imageEdgeInsets = UIEdgeInsetsMake(0, labelWidth02, 0, -labelWidth02);
