Button或TableViewCell连续点击事件

// 防止多次调用
#define kPreventRepeatClickTime(_seconds_) \
static BOOL shouldPrevent; \
if (shouldPrevent) return; \
shouldPrevent = YES; \
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)((_seconds_) * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ \
shouldPrevent = NO; \
}); \

宏定义

//在要执行的方法前面加上kPreventRepeatClickTime(0.5); 即可解决用户连续快速点击造成多执行的问题
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
     kPreventRepeatClickTime(0.5);
    UIViewController* detailVc = [[UIViewController alloc] init];
    [self.navigationController pushViewController:detailVc animated:YES];
}
-(void)buttnClick{
    kPreventRepeatClickTime(0.5);
     NSLog(@"点击了:  %ld次",++_nums);
}
