iOS 防止UIButton重复点击

 

使用UIButton的enabled或userInteractionEnabled

使用UIButton的enabled属性, 在点击后, 禁止UIButton的交互, 直到完成指定任务之后再将其enabled即可.

[btn addTarget:self action:@selector(nextStop:) forControlEvents:UIControlEventTouchUpInside];

 

- (void)nextStop:(UIButton *)sender { sender.enabled = NO; [self btnClicked]; }

 

- (void)btnClicked { dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ NSLog(@"btnClicked"); btn.enabled = YES; }); }
