当我执行 [self.navigationController popViewControllerAnimated:YES] 时，我的应用程序崩溃了。
它在设备上比在模拟器上崩溃更多。请建议如何解决这个问题？

最佳答案
myviewcontroller = [[[MyViewController alloc]init]autorelease];
[self.navigationController pushViewController:myviewcontroller animated:YES];
[myviewcontroller release]; //This is my bug !!! I just fixed it.
