UIImageView won't change size

Question

I am trying to alter the width and height of an UIImageView object but for some reason I can't.

This is the code I used:

-(void)setMenuImages
{ 
        self.menuImageButton.image=[UIImage imageNamed:@"myimage.jpg"]; 
        self.menuImageButton.frame=CGRectMake(0,0,20,150); 
}

What am I doing wrong? The (UIImageView) menuImageButton is not created programmatically, but from storyboard interface with initial leading, trailing, width and height constraints.

create iboutlet of height and width constraint given to imageButton and then set constant value of each as per requirement. — Yagnesh Dobariya, Apr 30 '18 at 08:25

You can self. menuImageButton.translatesAutoresizingMaskIntoConstraints = false in viewDidLoad and remove their constraints or you can add those constraints as IBOutlets and change them like

self.imageWidthConstraint.constant = 20;
self.imageHeightConstraint.constant = 150;

UPDATE

To declare constraints in your header file you need to select those constrains and right click drag to the .h file as show in the gif

translatesAutoresizingMaskIntoConstraints didn't work. How can I declare a constraint in a header file? – Student Apr 30 '18 at 08:29
Check my updated answer @Student, btw `translatesAutoresizingMaskIntoConstraints` only works if you don't have any constraint added to your `UIImageView` – Reinier Melian Apr 30 '18 at 08:39
