无法模拟发送给我的 iOS 崩溃报告

Question

我将我的应用程序发送到应用程序商店，但由于一些崩溃而被拒绝。我正在尝试模拟，在我的设备上运行该应用程序，但看不到任何崩溃日志。请帮助解释日志并给我一些想法为什么我无法在我的设备上模拟它。抱歉，我是 iOS 开发新手。

这是报告。

这是请求的代码

-(void) loadMeetings { 
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
  UITableViewController *myViewController = [[RootViewController alloc] initWithNibName:@"RootView" bundle:nil]; 
  myViewController.title = @"Meetings"; 
  myViewController.view.backgroundColor = [UIColor colorWithRed:.953 green:.965 blue:.886 alpha:1]; 
  [self.navigationController pushViewController:myViewController animated:YES]; 
  [spinner stopAnimating]; 
  [pool drain]; 
}

Answer 1

您正在从后台线程将新的视图控制器推送到导航控制器堆栈上。所有对 UIKit 的调用都必须在主线程上执行。检查 LoginView 上的 loadMeetings 方法，并找出为什么它首先在后台线程上发送。
