ios开发之单位时间内限制button的点击次数

-(void)timeEnough:(UIButton *)btn

{

btn.selected = NO;

}

-(void)btnClick:(UIButton *)btn

{

if (btn.selected)return;

btn.selected = YES;

[self performSelector:@selector(timeEnough:) withObject:nil afterDelay:3.0];

//你要实现的button点击事件

}

这样的效果就是该button在3秒内只能触发一次点击事件,防止button点击频率过快.
