我已经编写了在（TestView）中添加图像视图的代码。在UIview用于添加图像的触摸委托方法中，我点击视图中的任何位置，然后将图像添加到UIview（testview）中，并且该图像被添加到可变数组中，该数组是在 appdelegate 类中声明。另一个数组包含该图像的框架。每次点击添加图像时都会完成上述过程。在删除过程中，我们删除可变数组的图像和相关索引。我们还可以将任何图像移动到视图中的任何位置。

但是构建工作非常缓慢并且在 ipad 设备上崩溃并显示以下错误：-

            NSLog(@"Array Count After Deletion = %d",[appDelegate_iPad.marry_ContainsRect count]);
        }
      }
}

所以，请为我提供帮助。谢谢
