Question

I need to call a view contorller after selecting an image from imagePickerController , so I used this code :

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    imageEditorView = [[ImageEditorViewController alloc]initWithNibName:@"ImageEditorViewController" bundle:nil];
    imageEditorView.mainViewController = self;
    imageEditorView.imageBG = [info objectForKey:UIImagePickerControllerOriginalImage];

    [self presentViewController:imageEditorView animated:YES completion:nil];

}

but debugger gives me this warning :

Warning: Attempt to present <ImageEditorViewController: 0xaa42320> on
     <ViewController: 0x9b58680> whose view is not in the window hierarchy!

and nothing presents !

and if I dissMiss it first debugger gives me this error :

 Warning: Attempt to present <ImageEditorViewController: 0xa913980> on
 <ViewController: 0x9b332a0> while a presentation is in progress

!

EDITED

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease];
    } else {
        self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease];
    }
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

Use the following code like:

[self dismissViewControllerAnimated:YES completion:^{
   [self.parentViewController presentViewController:imageEditorView animated:YES completion:nil];
}];
