ios - 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 App Store，但由于某些崩溃而被拒绝。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不能在我的设备上模拟它。抱歉，我是 iOS 开发的新手。

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

您正在将一个新的 View Controller 从后台线程推送到导航 Controller 堆栈。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，找出它首先在后台线程上发送的原因。
