How can I set maximum width of a view in iOS?

My app have a basic login screen, an outer box and in it, some text fields and buttons. I set the box to fill the screen. However, on some devices this box will be too big. How do I set maximum width and height to a view?

You can do this programmatically 

some_view.widthAnchor.constraint(lessThanOrEqualTo: view.widthAnchor, multiplier: 0.45)        
some_view.heightAnchor.constraint(lessThanOrEqualTo: view.widthAnchor multiplier: 0.45)

0.45 is basically saying the width and height of some_view will be at maximum 45% of the width of the super view.

You can use auto-layout constraints so that the box adapts to the screen size, but does not exceed a given width and height. To do this, set a "less than or equal to" constraint on the width and height.

  1. Add top, bottom, leading, trailing, width and height constraints to the box.
  2. Set the priority of the top, bottom, leading and trailing constraints to High (750).
  3. Set the relation for the width and height constraints to Less Than or Equal (≤). The default value is Equal.
  4. Set the priority of the width and height constraints to Required (1000).
  5. Set the constant of the width and height constraints to the maximum size you want the box to be.

Set width constraint relation to Less Than or Equal

Set width constraint constant to 1000

Set leading and trailing constraint priority to 750

Try following code it may helps you

yourviewObject.frame=CGRectMake(yourviewObject.frame.origin.x,yourviewObject.frame.origin.y,self.view.frame.size.width,yourviewObject.frame.size.height)

Simple you use only four constraints (i.e Top space,Bottom space,Leading space,Trailing space) for that container view.

If you want to give a View's frame to fix all devices then use this width and height

self.view.frame.size.width,self.view.frame.size.height

Or You can give auto layouts Top Bottom Trailing and Leading constraints by dragging the View to its edges.

If you are using Interface Builder you could :

  • ctrl + clic your view and drag the blue arrow to the superview.

  • Hold shift and select "equal width" and "equal height"

  • Then go to the constraints of your view (little ruler icon) and set a multiplier like 0.5 to make your view width/height equal to half of its superview respective dimension.
