Subview equals width and height of superview (I always forget how to do such things in code) with autolayout

Autolayout - Stretch subview

[subview setTranslatesAutoresizingMaskIntoConstraints:NO];
[self.view addConstraints:[NSLayoutConstraint
                               constraintsWithVisualFormat:@"H:|-0-[subview]-0-|"
                               options:NSLayoutFormatDirectionLeadingToTrailing
                               metrics:nil
                               views:NSDictionaryOfVariableBindings(subview)]];
[self.view addConstraints:[NSLayoutConstraint
                               constraintsWithVisualFormat:@"V:|-0-[subview]-0-|"
                               options:NSLayoutFormatDirectionLeadingToTrailing
                               metrics:nil
                               views:NSDictionaryOfVariableBindings(subview)]];
