IOS7中的PushViewController崩溃 [英] PushViewController Crash in IOS7

问题描述

我在IOS7中遇到奇怪的问题当我尝试使用IOS6在xcode5中运行我的旧应用程序时，每件事情都运行良好，但是当我尝试推送Nextview时它与IOS7崩溃。这是我的应用程序崩溃的代码。

I am facing strange issue in IOS7 when I try to run my old app in xcode5 with IOS6 every thing working fine,but with IOS7 when I am trying to Push Nextview it Crash.Here is code where my app Crash.

 FamilyBioViewController *detailView=[[FamilyBioViewController alloc] initWithNibName:@"FamilyBioView" bundle:[NSBundle mainBundle]];
 [self.navigationController pushViewController:detailView animated:YES];
 [detailView release];

当发生崩溃时，它没有在控制台中显示任何错误。下面的屏幕截图显示崩溃结果

有趣的是当我用 presentViewController <来呈现我的视图时/ strong>而不是
pushViewController 然后它在IOS 7中正常工作。

When crash happened it did not show any error in console.The below screenshot show the crash result Interesting thing is when I present my view with presentViewController instead of pushViewController then it is working fine in IOS 7 .

FamilyBioViewController *detailView=[[FamilyBioViewController alloc] initWithNibName:@"FamilyBioView" bundle:[NSBundle mainBundle]];
 [self presentViewController:detailView animated:YES completion:nil];
 [detailView release];

所以问题是为什么pushViewController会导致IOS7出现问题？任何帮助将不胜感激。谢谢。
