iPhone:具有多个响应水龙头的区域的自定义UITableViewCell? [英] iPhone: Custom UITableViewCell with multiple areas that respond to taps?

问题描述

我被要求创建一个具有多个可以点击的区域的自定义UITableViewCell.

I've been asked to create a custom UITableViewCell with multiple areas that can be tapped.

这些区域将没有按钮或任何图形-它们将是不可见的.根据用户点击的单元格的哪三分之一(即

These areas won't have buttons or any graphics - they'll be invisible. 3 different methods will be called depending on which third of the cell the user taps i.e.

||decrementFooCount ||viewFooDetails ||crementFooCount ||

|| decrementFooCount || viewFooDetails || incrementFooCount ||

该单元格上有一些需要始终可见的标签-fooName和fooCount.

The cell has a few labels on it that need to be visible at all times - the fooName and fooCount.

我在想单元格上可能有三个隐藏的UIButton?

I'm thinking perhaps three hidden UIButtons over the cell?

我还需要保持滑动以删除默认行为.

I also need to maintain the swipe to delete default behavior.

推荐答案

您可以将UITableViewCell子类化，并覆盖 touchesBegan:withEvent:方法.然后，您可以获取触摸位置的CGPoint.

You can subclass your UITableViewCell and override the touchesBegan:withEvent: method. You can then get a CGPoint of where the touch was placed.

- (void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event {
   UITouch* touch = touches.anyObject;
   CGPoint location = [touch locationInView:self];

   if (CGRectContainsPoint(myTestRect, location)) {
       // Touched inside myTestRect, do whatever...
   } else {
      // Let the default implementation take over.
      [super touchesBegan:touches withEvent:event];
   }
}
