Objective C，UITabBar EXC_BAD_ACCESS
我有 UITabBar，它有 5 个菜单。第三个菜单从我的网络服务器下载图像并在 UIImageView 中显示该图像。
问题是，每当我在下载图像后尝试返回第一个菜单时，它就会爆炸......堆栈跟踪看起来像这样
obj_msgSend
??
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(Hierarchy) _postMovedFromSuperView:]
如果我注释从服务器获取图像的代码，那么它就可以正常工作...... 这里可能有什么问题？
I have UITabBar which has 5 menus. Third menu downloads an image from my web server and shows the image in the UIImageView.
The problem is that whenever if I try to go back to the first menu after download the image then it blows up...The stack trace looks like this

-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]

-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(internal) _didMoveFromWindow:toWindow:]
-[UIView(Hierarchy) _postMovedFromSuperView:]
If I comment the code that gets the image from server out then it works fine..
What might be the problem here?

嗯，尝试发布下载导致崩溃的图像的代码。 EXEC_BAD_ACCESS 通常在您尝试访问已释放的变量时发生。
Hmm, try to post code for downloading image that creates crash. EXEC_BAD_ACCESS happens usually when you try accessing variable that you have already released.
