iphone - 应用程序 7 分钟后无法正常工作？

Question

我正在开发 iPhone 应用程序。该应用程序在前 6 或 7 分钟内运行良好，但此后我的应用程序的某些功能无法运行。例如，我在我的应用程序中使用 NSTimer 使用时钟音效，它可以工作 6 或 7 分钟，然后它会自动静音并第二次执行此代码，

   -(IBAction)retryagain
   {    
    PlistDemoViewController *sec=[[PlistDemoViewController alloc] initWithNibName:@"PlistDemoViewController" bundle:nil];
    [self presentModalViewController:sec animated:YES];
    [sec release];
    }

这段代码在 6 或 7 分钟之前工作正常。但之后它崩溃了，我的控制台看起来像这样。

有人可以指导我解决这个问题吗？

编辑 2:

您会尝试使用此代码吗？

PlistDemoViewController *sec= [[PlistDemoViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:sec animated:YES];

由于您的 Nib 是以 Controller 命名的，因此应该执行相同的操作；我只希望，不要崩溃......

编辑:

如果您仔细阅读错误消息:

'Could not load NIB in bundle: 'NSBundle (loaded)' with name 'PlistDemoViewController

它说找不到PlistDemoViewController。

你能检查一下名字拼写是否正确吗？

旧答案:

您正在 PlistDemoViewController retryagain 方法中呈现模态视图，但它失败了。我的建议是你检查您传入的所有参数，并仔细检查您尝试显示的 xib 的定义。
