Iphone: Problem with moving back and forth between two UIViewController
- by Harry Pham
Let me first describe the context of the problem. I have 2 UIViewController call AdminViewController and ButtonReorderViewController. AdminViewController contain 1 button. ButtonReorderViewController contains 1 button and 1 picture. Button in AdminViewController tie to an event call goToReorderButton. The content of goToReorderButton are below:
ButtonReorderViewController *buttonReorder = [[ButtonReorderViewController alloc] initWithNibName:@"ButtonReorderViewController" bundle:[NSBundle mainBundle]];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:buttonReorder]; //Add a Navigation Controller to the root view
[navController setNavigationBarHidden:TRUE];
buttonReorder = (ButtonReorderViewController *) navController;
[[buttonReorder view] setFrame:CGRectMake(0, -20, 320, 470)];
[self.view addSubview:buttonReorder.view];
I use UINavigationController to allow me to swipe left and right.So I am in AdminViewController, and I click on goToReorderButton, it load ButtonReorderViewController. I am able to swipe left and right (awesome !!!) So I click the button in ButtonReorderViewController call goToAdmin, simply to go back to the AdminViewController
-(void) goToAdmin{
[self.view removeFromSuperview];
}
However, as soon as I go back to AdminViewController, I cant click anything at all. The program does not seg fault, it just that I cant click the button at all. if I remove the line buttonReorder = (ButtonReorderViewController *) navController; inside goToReorderButton, then everything work fine. Any idea how to fix this?
