Question

how do you use UiimageView to show an image to make sure the imageview is the correct size of the UIImage? thanks!

Answer 1

This code should create an imageView with the frame of your image automatically.

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"ImageName"]];

A little background from the docs.

This method adjusts the frame of the receiver to match the size of the
specified image. It also disables user interactions for the image view
by default.
