iOS防止按钮快速连续点击造成多次响应的方法

	//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;
