Question

I’m realizing what a newbie I still am with this problem I have. I am trying to present a modal window in a project I am working on and it’s not appearing. My solution was then to create an absolute basic project and get it working there first, so I would clearly understand my problem, but I can’t get even this working 🙁

I add a ViewController to the MainWindow at applicationDidFinishLaunching. In this ViewControllers XIB, I have a button. The ViewController has the following header:

#import <UIKit/UIKit.h>
#import "ModalView.h"

@interface ViewBasedViewController : UIViewController {
    ModalView *modalView;
}

- (IBAction)dooooIt :(id)sender;

@property (nonatomic, retain, readonly) ModalView *modalView;

@end

And methods:

#import "ViewBasedViewController.h"

@implementation ViewBasedViewController

@synthesize modalView;

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];

}

- (void)viewDidUnload {
}


- (void)dealloc {
    [super dealloc];
    [modalView release];
}

- (ModalView *)modalView {
    if (modalView == nil) {
        modalView = [[ModalView alloc] initWithNibName:@"ModalView" bundle:nil];
    }
    return modalView;
}

- (IBAction)dooooIt :(id)sender {

    [self.navigationController presentModalViewController:modalView animated:YES];

}

@end

I’m obviously missing something very simple and I believe it’s between my ears at this stage 🙂

Does anyone want to put a poor fella out of his misery?

Many Thanks

Chris

Answer 1

For those that may come across this problem and were as baffled as I was, I fell over the solution. There was two problems in the dooooIt method:

- (IBAction)dooooIt :(id)sender {
    [self presentModalViewController:self.modalView animated:YES];

}

I should have included ‘self’ when referring to the modalView property (otherwise it’s nil) and I shouldn’t have referred to the navigationController as I had none hooked up.

Hope this helps any of you (amazing what a glass of wine can do! 🙂
