I understand your question partially . See if following helpful :

In your scroll view :

<pre><code> for (int i=0;i&lt;array;i++)
 {
 UIButton *button=[[UIButton alloc]initWithFrame:CGRectMake(scrollWidth, 5,50,40)];
 button.userInteractionEnabled=YES;
 UITapGestureRecognizer *rcognizer=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buttonSelcted:)];
 [button addGestureRecognizer:rcognizer];
 [scrollView addSubview:button];
 scrollWidth=scrollWidth+80;
 }
</code></pre>

In buttonSelected method just do following :

<pre><code>-(void)buttonSelected:(UITapGestureRecognizer *)recognizer
{
 UIButton *selectedItem=(UIButton*)recognizer.view;
 //do what you want with button
}
</code></pre>

In all your buttons <code>setExclusiveTouch</code> on. As:

<pre><code>[button setExclusiveTouch:YES];
</code></pre>

I have a main view controller class which contains a <code>UIScrollView</code> and a number of subviews like cards.

Each card is an object and it is covered with a <code>UIButton</code>. I want to detect a tap on the <code>UIButton</code> and want to disallow taps on multiple cards at a time.

Detect a touch on a subview in a main controller

我有一个主视图控制器类，它包含一个UIScrollView和许多像卡片一样的子视图。每张卡都是一个对象，并且它被一个UIButton所覆盖。我要检测UIButton上的点击，并禁止同时点击多张卡。
