Unfortunately this is not the complete truth. It is also YES for document views of NSScrollViews, and cannot be disabled even in the latest versions of Xcode that I have tried. I have a view that manages its relationship to its enclosing clip view using constraints, and I obviously need to disable translatesAutoresizingMaskIntoConstraints for this to work properly. And because of the way that nib unarchiving works, -setTranslatesAutoresizingMaskIntoConstraints: is called *after* -initWithFrame:/-initWithCoder:. So the solution I've been using is to override -updateConstraints to call [self setTranslatesAutoresizingMaskIntoConstraints:NO] before calling super. I suppose I could instead override -translatesAutoresizingMaskIntoConstraints like so: - (BOOL)translatesAutoresizingMaskIntoConstraints { if ([self superview] == [[self enclosingScrollView] contentView]) return NO; else return [super translatesAutoresizingMaskIntoConstraints]; } ...but it's not documented whether the constraint system calls -translatesAutoresizingMaskIntoConstraints, or uses an internal flag to represent that state. Also, IB doesn't let you edit the autoresizing mask of a view in a nib with autolayout turned on, even if that view is a top-level view and should have translatesAutoresizingMaskIntoConstraints=YES because it's going to be installed in a view hierarchy you don't control. This is also incredibly unhelpful. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
