我正在设置url方案,并且从另一个应用程序启动该应用程序,但是传递主机或url不能像现在这样工作。我正在为所有的视图布局使用故事板和界面构建器。
该指南在appDelegate中显示此openURL:
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{ if([[url host] isEqualToString:@"page"]){ if([[url path] isEqualToString:@"/page1"]){ [self.mainController pushViewController:[[Page1ViewController alloc] init] animated:YES]; } return YES; } }
这是我的版本简化,并从其他几个来源,即
Get Instance Of ViewController From AppDelegate In Swift我正在跳过url主机的条件,以删除问题中的潜在的其他变量。
func application(application: UIApplication,openURL url: NSURL,sourceApplication: String,annotation: AnyObject?) -> Bool { var rootViewController = self.window!.rootViewController let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main",bundle: nil) var profileViewController = mainStoryboard.instantiateViewControllerWithIdentifier("profile") as ProfileViewController rootViewController.navigationController.popToViewController(profileViewController,animated: true) return true }
迅速版本导致崩溃:
致命错误:在解开可选值时意外发现为零
看来rootViewController还没有一个navigationController?
一行代码:
self.navigationController!.pushViewController(self.storyboard!.instantiateViewControllerWithIdentifier("view2") as UIViewController,animated: true)
