<请给我一些建议。

解决方案

的UINavigationController 维护 viewControllers 并且根控制器始终位于 0 。

  MyAController * myController =（MyAController *）[self.navigationController.viewControllers objectAtIndex：0]; 
 myController.myText = @My String; 
 [self.navigationController popToViewController：myController animated：YES];

Please give me suggestion.

解决方案

UINavigationController maintain the list of all pushed controller in viewControllers and the root controller always reside at 0.

MyAController *myController = (MyAController *)[self.navigationController.viewControllers objectAtIndex:0];
myController.myText = @"My String" ;
[self.navigationController popToViewController:myController animated:YES];
