Visual formatting language, button width and height constraint

autolayout, ios, nslayoutconstraint, objective-c, swift

Solution

Two possible options:

[view setTranslatesAutoresizingMaskIntoConstraints:NO];
NSArray* vConstraints = [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[view(25)]|" options:0 metrics:nil views:view]];
[parentView addConstraints:vConstraints];

or

NSLayoutConstraint* vConstraint = [NSLayoutConstraint constraintWithItem:view attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:25];
[parentView addConstraint:vConstraint];

Problem

Is there any way to set UIView width and height with NSLayoutConstraints? for example i have the following constraint setup ``` subView.setTranslatesAutoresizingMaskIntoConstraints(false); let cons:NSArray = NSLayoutConstraint.constraintsWithVisualFormat("[subView(99)]", options:nil, metrics: nil, views: ["subView":subView]); self.view.addConstraints(cons); ``` this sets only width, how to add also a height?
