There are several ways to constraint a CALayer, although you cannot use NSLayoutConstraints. Most flexible way is to sub-class CALayer and override - (void)layoutSublayers;. Then you can position and size your content however you want. A simpler and more limited approach is to set the layer's contentsGravity property. With this you can set the layer to (for example) always position content in a corner, or do aspect fill.
