Launching a modal UINavigationController
- by Alexi Groove
I'd like to launch a modal view controller the way one does with 'ABPeoplePickerNavigationController' and that is without having to creating a navigation controller containing the view controller.
Doing something similar yields a blank screen with no title for the navigation bar and there's no associated nib file loaded for the view even though I am invoking the initWithNibName when the 'init' is called.
My controller looks like:
@interface MyViewController : UINavigationController
@implementation MyViewController
- (id)init {
NSLog(@"MyViewController init invoked");
if (self = [super initWithNibName:@"DetailView" bundle:nil]) {
self.title = @"All Things";
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"All Things - 2";
}
@end
When using the AB controller, all you do is:
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
ABPeoplePickerNavigationController is declared as:
@interface ABPeoplePickerNavigationController : UINavigationController
The other way to create a modal view as suggested in Apple's 'View Controller Programming Guide for
iPhone OS':
// Create a regular view controller.
MyViewController *modalViewController = [[[MyViewController alloc] initWithNibName:nil bundle:nil] autorelease];
// Create a navigation controller containing the view controller.
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController];
// Present the navigation controller as a modal view controller on top of an existing navigation controller
[self presentModalViewController:secondNavigationController animated:YES];
I can create it this way fine (as long as I change the MyViewController to inherit from UIViewController instead of UINavigationController). What else should I be doing to MyViewController to launch the same way as ABPeoplePickerNavigationController?
