Answer 1

In interface Builder, access the Mode menu inside of the detail pane (the fourth one) and choose the right one for your UIImageView (I guess "center" or "aspect fit").

A constant that specifies how the layer's contents are positioned or scaled within its bounds.

       @property(copy) NSString *contentsGravity

Answer 2

In Interface Builder, use the following configuration:

There are two important settings, namely:

1. Mode: Aspect Fill

2. Clip Subviews

It can also be done programmatically:

[imageView setContentMode:UIViewContentModeScaleAspectFill];
[imageView setClipsToBounds:YES];

This will correctly fill the view with the image, keep its aspect ratio and hide what doesn't fit.

Answer 3

Use an UIImageView and do

imageView.contentMode = UIViewContentModeScaleAspectFit;

Answer 4

make a IBOutlet in your controller.

@property (retain)IBOutlet UIImageView* imageView;

and in -(void) viewDidLoad set

imageView.layer.masksToBounds = YES;
