第一种,按钮点击后关闭交互，等几秒之后才允许交互
使用CGD

- (void)clickBtn:(UIButton*)btn{
btn.enabled = NO;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
btn.enabled = YES;
});
}

使用延时方法,没使用GCD方便，算是一种扩展思路

- (void)clickBtn:(UIButton*)btn{
btn.enabled = NO;
//点击按钮后先取消之前的操作，再进行需要进行的操作
[[self class] cancelPreviousPerformRequestsWithTarget:self selector:@selector(allowBtnClicks:) object:btn];
[self performSelector:@selector(allowBtnClicks:) withObject:btn afterDelay:1.0f];
}
- (void)allowBtnClicks:(UIButton*)btn{
btn.enabled = YES;
}

第二种，使用runtime为UIButton增加属性
- 1.创建一个UIButton的分类，使用runtime为button增加一个时间间隔属性
- 2.然后重写UIButton的点击方法，使用GCD延时来选择button是否可以交互

@interface UIButton (One)
@property (nonatomic, assign) NSTimeInterval acceptEventInterval;//添加点击事件的间隔时间
