我将我的XCode更新为4.2,并希望使用Simulator 5.0而不是4.3。
我使用5个标签编写了一个标签栏应用程序,但是通过appdelegate将另一个视图作为第一个视图推送。
现在我遇到的问题是它在模拟器4.3中运行良好,但在模拟器5.0中出现错误:
int retVal = UIApplicationMain(argc, argv, nil, nil); SIGABRT

我将问题本地化在AppDelegate中:
AppDelegate *app = [AppDelegate getApp];
app.tabController.selectedViewController = connNavController;
我还尝试使用
推送控制器[self.navigationController pushViewController:myViewController animated:YES];
但我总是得到一个SIGABRT。
清洁目标,重新启动等不起作用。
如果您有解决方案,请提供帮助。
谢谢!

UIApplicationMain(argc, argv, nil, nil);
与
UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

您可以从堆栈跟踪中判断一下,但是当您使用属性selectedViewController
时,查看控制器大部分位于viewcontrollers
的{{1}}数组中,如果它不在数组会像这种情况一样抛出错误。
因此,请确保您的代码中包含此内容:
UITabBarController
