Unable to get presentViewController to work
ipad, iphone, presentmodalviewcontroller, xcode
Solution
If `ViewController` is the root view controller, it can't present a modal view controller from within its own `viewDidLoad`, because at that point it doesn't have information like the screen size.
If other view controllers have already displayed, this will work. If the root view controller is a `UINavigationController`, you will see a view sliding in from the right while the modal view slides up from the bottom.
Anyway, for your `ViewController`, the soonest you could present it is after it has become visible. Using a timer for this is unreliable; older and slower devices have dramatically longer load times.
For more reliability, implement `viewDidAppear:` for `ViewController`. Do still use your timer system to add an additional delay; a fraction of a second should be sufficient. Although presenting the modal view controller from within `viewDidAppear` worked for me in the iOS 5.1 simulator, Presenting a modal view controller when loading another ViewController says it sometimes doesn't happen.
Problem
I copied a working viewcontroller class from another project into a new project. I can't get the view to load in the new project. In the old project I used presentModalViewController. In the new I cannot get the view to load using either presentModalViewController or presentViewController I am trying to load the present the view from my main view controller. Here is what my main view controller interface looks like... ``` // ViewController.h #import <UIKit/UIKit.h> #import "RequestDialogViewController.h" @interface ViewController : UIViewController <RequestDialogViewControllerDelegate> { } - (void)requestDialogViewDidDismiss:(RequestDialogViewController *)controller withResponse:(NSString*)response; ``` I am using presentModalViewController like this... ``` RequestDialogViewController *requestIPViewController = [[RequestDialogViewController alloc] initWithNibName:@"RequestDialogViewController" bundle:nil]; navigationController = [[UINavigationController alloc] initWithRootViewController:requestIPViewController]; [self presentModalViewController:navigationController animated:YES]; ``` and presentViewController like this... ``` RequestDialogViewController *requestIPViewController = [[RequestDialogViewController alloc] initWithNibName:@"RequestDialogViewController" bundle:nil]; [self presentViewController:requestIPViewController animated:YES completion:nil]; ``` What am I missing in the new project? The init method fires, but viewDidLoad does not and nothing is displayed. Thanks
