Question

MoviePlayerAppDelegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
    window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    viewController = [[MoviePlayerViewController alloc] init];
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];
}

MoviePlayerViewController.m

-(void)loadView {
    //Setup the view.
    [self setView:[[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]];
    [[self view] setBackgroundColor:[UIColor grayColor]];
    [[self view] setUserInteractionEnabled:YES];

    //Add play button.
    playButton = [[UIButton alloc] initWithFrame:CGRectMake(53, 212, 214, 36)];
    [playButton setBackgroundImage:[UIImage imageNamed:@"playButton.png"] forState:UIControlStateNormal];
    [playButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [[self view] addSubview:playButton];
}

But somehow view is not loading. I could not find mistake in code. Please help to resolve this. Thanks in advance.

Try this:

Remove the code

window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

and change addSubView as below.

[self.window addSubview:viewController.view];

[self.window makeKeyAndVisible];
