从超级视图中删除时 EXC_BAD_ACCESS

发布于 2024-12-17 17:43:41 字数 360 浏览 5 评论 0原文

我的项目使用ARC，所以我不能使用保留或释放，在ViewController A中，我初始化ViewController B并将其视图添加为子视图：

ViewControllerB *viewB = [[ViewControllerB alloc] init];

[self.view addSubview:viewB.view];

在ViewControllerB中，我制作一个按钮，当用户单击它时，视图将被删除来自超级视图：

[self.view removeFromSuperview];

结果是 EXC_BAD_ACCESS。请帮助我，对我的英语感到抱歉。

My project using ARC, so I can't use retain nor release, in ViewController A, I init ViewController B and add its view as a subview:

ViewControllerB *viewB = [[ViewControllerB alloc] init];

[self.view addSubview:viewB.view];

And in ViewControllerB, I make a button and when user click on it, the view will removed from superview:

[self.view removeFromSuperview];

And the result is EXC_BAD_ACCESS.
Please help me and sorry about my English.

我认为 viewB 不是局部变量。

我也有同样的问题..

尝试这样的事情：

NSLog("self.view retain count: %d", self.view.retainCount);
[self.view removeFromSuperview];
NSLog("self.view retain count: %d", self.view.retainCount);

或者：

NSLog("self.view.superview retain count: %d", self.view.superview.retainCount);
[self.view removeFromSuperview];
NSLog("self.view.superview retain count: %d", self.view.superview.retainCount);

这不是一个好的做法，但也许你会发现内存泄漏错误...
如果您使用 ARC - 它不能保护您免受内存管理错误的影响...

如果出现问题，我很抱歉我的英语。

I have the same problem too..

Try something like this:

NSLog("self.view retain count: %d", self.view.retainCount);
[self.view removeFromSuperview];
NSLog("self.view retain count: %d", self.view.retainCount);

or:

NSLog("self.view.superview retain count: %d", self.view.superview.retainCount);
[self.view removeFromSuperview];
NSLog("self.view.superview retain count: %d", self.view.superview.retainCount);

It's not good practice, but maybe you will catch a memory leak error...
If you are using ARC - it doesn't protect you from memory management errors...

I'm sorry for my English if something wrong.
