ViewController永远不会被释放 [英] ViewController never gets deallocated

问题描述

在我看来，应该在使用以下代码弹出根视图控制器的同时，将myViewController释放，但是我再也看不到释放消息出现NSLogged.

In my mind, myViewController should be deallocated around the time that I pop back to the root view controller with the following code, but I never see the deallocation message getting NSLogged.

如果这行得通，那么我在myViewController的类中会寻找什么样的问题，而当我弹出popToRootViewController时，该类问题可能导致它被释放?

If this should work, then what kind of problem can I look for in the myViewController's class that might cause it to get deallocated when I popToRootViewController?

谢谢.

在我的tableView中调用以下内容:

The following gets called in my tableView:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

MyViewController *vc = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];

[self.navigationController pushViewController:vc animated:YES];

[vc release];
}

更新:

这段代码很完美，但是由于我的自定义视图控制器中的一些内存管理不善，导致两者均未释放.我有一些保留属性应该改为分配(或至少是我解决它的方法).有关详细信息，请参见评论.

This code was perfect, but it was some bad memory management in my custom view controllers that caused neither to be released. I had some retained properties that should have been assign instead (or at least, that's the way I solved it). See comments for specifics.

@ JaySmith02是正确的

@JaySmith02 is right

在我看来，罪魁祸首是

@property (nonatomic, retain) id<TTSlidingPagesDataSource> dataSource;

从我写的时候的viewController

From my viewController when I wrote

slidingPages.dataSource = self

我猜想 dataSource 保留了我的 viewController 并进行了循环保留.我的 viewController 的'dealloc'从未被调用过.

I guess the dataSource retained my viewController and made a circular retention. The 'dealloc' of my viewController was never getting called.

注意:确实在ARC下调用了 dealloc .区别在于您无法调用 [super dealloc]

Note: Under ARC dealloc does get called. Difference is you cannot call [super dealloc]

解决方案:

@property (nonatomic, assign) id<TTSlidingPagesDataSource> dataSource;
