Question

For a Universal App, how do I set the UIImageView frame in the ViewController?

UIView *baseView = [[UIView alloc] init];

[self.view addSubview:baseView];

// Displays UIImageView

UIImageView *myImage = [[UIImageView alloc]
                        initWithImage:[UIImage imageNamed:@"tool.png"]];
[baseView addSubview:myImage];

When I run app it shows black screen. So i guess I have to set a frame for it.

You kinda answered your own question – yes you have to set a frame for it.
You may want to try:

UIView *baseView = [[UIView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:baseView];

// Displays UIImageView

UIImageView *myImage = [[UIImageView alloc]
                    initWithImage:[UIImage imageNamed:@"tool.png"]];
myImage.frame = baseView.bounds;
[baseView addSubview:myImage];

You could also set the autoresizingmask for baseView and myImage so that as self.view’s frame changes, so do these two views.

Also, just in case you aren’t using ARC – don’t forget to autorelease these views before leaving this method.
