iOS防止按钮快速连续点击造成多次响应的方法

new_gist_file

//1.在每次点击时先取消之前的操作
- (void)buttonClicked:(id)sender
{
   //这里是关键，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(buttonClicked:) object:sender];
   [self performSelector:@selector(buttonClicked: )withObject:sender afterDelay:0.2f];
}
//2.点击后将按钮置为不可点击状态，几秒后恢复
-(void)buttonClicked:(id)sender{
   self.button.enabled = NO;
   [self performSelector:@selector(changeButtonStatus) withObject:nil afterDelay:1.0f];//防止用户重复点击
}

-(void)changeButtonStatus{
    self.button.enabled = YES;
}
