推荐答案

您也可以这样做：

首先定义图像所在的矩形：

first define the rect where you image will be:

touchRect=CGRectMake(screen.width/2-screen.width/8, 0, screen.width/4, screen.height/5);

然后使用touchesEnded方法，您可以定义触摸该区域时要执行的操作：

then with touchesEnded method you can define what you want to do when you touch over that zone:

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

        CGPoint targetPoint = [[touches anyObject] locationInView:self];
        if (CGRectContainsPoint(touchRect,  targetPoint)){
            //YOUR CODE HERE
        }
}
