从块中解除模态视图时Dealloc不运行 [英] Dealloc Not Running When Dismissing Modal View from Block

问题描述

这里奇怪的是，当从一个区块内被解雇时，dealloc没有被调用。代码：

Strange one here, dealloc is not being called when dismissed from inside a block. Code:

[[NSNotificationCenter defaultCenter] addObserverForName:@"user.login" object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *notif) {

[self dismissModalViewControllerAnimated:YES];

 }];

任何人都知道为什么会这样？我如何从块中解除并同时运行dealloc？

Anyone know why this would be the case? How can i dismiss from inside the block and run dealloc at the same time?

我尝试过自动执行器，但这没有任何区别。

I have tried self performselector but this did not make any difference.

谢谢

推荐答案

我推荐你：块中自我引用的计数

该块将保留 self 直到块被释放。因此，对于dealloc self ，您需要删除观察者。

The block will retain self until the block is released. So to dealloc self, you'll need to remove the observer.
