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.

Answer 1

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
