Where to set translatesAutoresizingMaskIntoConstraints in Xcode 4.5

I'm late to this question, but the mentioned option is still missing in Xcode 5 & 6, so the question is still meaningful.

Actually, we can always set a value to any property of a view/control/object by adding a User Defined Runtime Atribute in Storyboard (Interface Builder) like the following screenshot.

And it also works for translatesAutoresizingMaskIntoConstraints. So the question could be solved.

This is a great question - and one I've tried to find an answer to myself. Sadly, it looks like there is no "quick fix". Currently, Apple considers Constraint-based layout Opt-in - even naming a section of the UIView Class Reference:

Opting in to Constraint-Based Layout

But that Opt-in is not global. I presume this is because not everything looks good if you just turn Springs & Struts into Constraints. Some UI elements break, or you would get a ton of unsatisfiable constraints errors.

I can think of one possible solution - I have not tried it myself, but you could make a category on UIView that sets all UIView objects to return NO for - (BOOL)translatesAutoresizingMaskIntoConstraints. While I do not know what this would break, it would globally set translatesAutoresizingMaskIntoConstraints to NO.

Here is a good introduction to Categories if you want to learn more about them!

When u have to change the size or position of your subview. Use (BOOL)translatesAutoresizingMaskIntoConstraints method before you set the frame of your subview.

[self.benchmarkButton removeFromSuperview];[self.benchmarkButton setTranslatesAutoresizingMaskIntoConstraints:YES];[self.benchmarkButton setFrame:CGRectMake(20, self.benchmarkButton.frame.origin.y+40, 260, 30)];[self.benchmarksView addSubview:self.benchmarkButton];

Thats way your subview will not fight from constraints as it is default (AutoLayout) in Xcode 4.3 and later. Thanks
