我不断收到以下错误:

这就是我正在做的事情.在视图控制器中，当按下某个按钮时，我会调用以下命令:
Here is what I am doing. From a view controller, I call the following when a certain button is pushed:
EventsViewController *viewController = [[EventsViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
navController.navigationBar.tintColor = [UIColor blackColor];
[self presentModalViewController:navController animated:YES];
[viewController release];
[navController release];
然后，如果在 EventsController 中按下某个按钮，我调用:
Then, if a certain button is pushed in EventsController, I call:
SingleEventViewController *viewController = [[SingleEventViewController alloc] initWithEvent:[currentEvents objectAtIndex:indexPath.row]];
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
然后，如果在 SingleEventViewController 中按下某个按钮，我调用:
Then, if a certain button is pushed in SingleEventViewController, I call:
EventMapView* viewController = [[EventMapView alloc] initWithCoordinates];
[[self navigationController] pushViewController:viewController animated:YES];
[viewController release];
是的，很明显有嵌套的推送动画，但这不是正确的做法吗?我查看了 Apple 的 DrillDownSave 代码，这似乎是他们的做法.我使用 init 方法而不是 viewDidLoad 方法是否重要?
So yea, it's obvious that there's nested push animations, but isn't this the right way to go about it? I checked out Apple's DrillDownSave code and this appears to be how they're doing it. Does it matter that I use init methods instead of viewDidLoad methods?
我想通了.显然，如果您从 UITableViewDelegate 的 -didSelectRowAtIndexPath 方法之外调用 -pushViewController，它就不起作用.将调用移到该函数中有效.很奇怪.
I've figured it out. Apparently if you call -pushViewController from outside of the -didSelectRowAtIndexPath method of a UITableViewDelegate, it doesn't work. Moving the call into that function worked. Weird.
