Question

Why is Ipad simulator in XCode 4.5.1 shows wrong size when checking out programatically?

MainViewController.m

- (void)viewDidLoad{
    [super viewDidLoad];

    [self.view setBackgroundColor:[UIColor redColor]];

    NSLog(@"self.view width : %f",self.view.frame.size.width);
    NSLog(@"self.view height : %f", self.view.frame.size.height);

    mTextView  =   [[UITextView alloc] initWithFrame:CGRectMake(10.0, 10.0, self.view.frame.size.width - 20, self.view.frame.size.height/2)];
    [self.view addSubview:mTextView];
}

and I am getting output as

self.view width : 320.000000
self.view height : 548.000000

My project specification

1. Universal project
2. targeting iOS 6.0
3. I am absolutely certain that I checked “targeted for ipad”
   checkbox when creating MainViewController
4. Dont know whether it is important, but “with xib for user interface”
   was unchecked.

And here is a screen shot with a textview is added

Try waiting until:

- (void)viewWillAppear

before setting the frame of your UITextView. According to this post you won’t have valid geometry for your view before then.
