のObj-C

NSLayoutConstraint * widthConstraint = [btnMenu.widthAnchor constraintEqualToConstant:25]; 
NSLayoutConstraint * heightConstraint =[btnMenu.heightAnchor constraintEqualToConstant:25]; 
[widthConstraint setActive:YES]; 
[heightConstraint setActive:YES]; 

UIBarButtonItem* btnMenuItem = [[UIBarButtonItem alloc] initWithCustomView: btnMenu]; 
self.navigationItem.leftBarButtonItem = btnMenuItem; 

スウィフト

let widthConstraint = button.widthAnchor.constraint(equalToConstant: 25) 
let heightConstraint = button.heightAnchor.constraint(equalToConstant: 25) 
heightConstraint.isActive = true 
widthConstraint.isActive = true
