Hi all, I am trying to add a layout constraint to my container view programmatically by putting the following code in the view controller (which I got and modified from Apple's UIViewController docs): ------------- [toolbar setTranslatesAutoresizingMaskIntoConstraints: NO]; id topGuide = self.topLayoutGuide; NSDictionary *viewsDictionary = NSDictionaryOfVariableBindings (toolbar, topGuide); [self.view addConstraints: [NSLayoutConstraint constraintsWithVisualFormat: @"V: [toolbar]-20-[topGuide]" options: 0 metrics: nil views: viewsDictionary]]; [self.view layoutSubviews]; // You must call this method here or the system raises an exception ------------- "toolbar" is a UIToolBar at the top of the view.
This doesn't work. I get the following: 'NSInvalidArgumentException', reason: 'Unable to parse constraint format: Expected a view V: [toolbar]-20-[topGuide] ^' Does anyone have any ideas where I am going wrong? I tried using the view instead of topGuide, but got the same error message. I am trying to keep the tool bar from underlapping the status bar in iOS 7, while keeping iOS 6 compatibility. (Xcode 5.0.2, Base SDK iOS 7.0) Thanks, Don ------------ Don Hall Apps & More Software Design, Inc. http://www.appsandmore.com d...@appsandmore.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
