Question

I have subclassed UIView, but I need to prevent the frame from changing, so I tried overriding the setFrame: method and just ignoring the value passed, and creating my own CGRect base on self.superview and passing it to [super setFrame:

How can I make the UIView’s frame unchangeable? (from within the subclass)

Answer 1

Step1: Override setFrame to do nothing.

- (void)setFrame:(CGRect)newRect
{
}

Step 2: Move your semi-static frame setting into your overridden version of willMoveToSuperview: to get a valid superview reference.

- (void)willMoveToSuperview:(UIView *)newSuperview
{
   CGRect newFrame = newSuperview.frame;
   //manipulate the frame here
   [super setFrame:newFrame];
}
