UIViewController *topRootViewController = [UIApplication sharedApplication].keyWindow.rootViewController; while (topRootViewController.presentedViewController) { topRootViewController = topRootViewController.presentedViewController; } //[topRootViewController presentViewController:yourController animated:YES completion:nil]; //or [topRootViewController myMethod];
解决办法2：
UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; LoginViewController* loginViewController = [mainstoryboard instantiateViewControllerWithIdentifier:@"LoginViewController"]; [self.window makeKeyAndVisible]; //[LoginViewController presentViewController:yourController animated:YES completion:nil]; //or [LoginViewController myMethod];
