How to set a subview's frame

Question

I have a view hierarchy under a UIViewController that consists of a main view and a few subviews of the main view, all defined in a storyboard, and all connected using IBOutlet.

I would like to set the position and size of the subviews relative to the main view.

I've tried setting them in viewDidLoad and viewWillAppear . Neither work, and when called, the main view has valid frame values but the subviews all have frames of (0,0,0,0).

If I do nothing, the subviews appear exactly where positioned on the storyboard. I need to make the following code work, but I don't know where to put it.

CGRect newFrame = CGRectMake(10,10,50,50);
[subView setFrame:newFrame];

Another way to ask this question:
Where and when do the frames of storyboard subviews get set?
Or, should I just create all the subviews with code?

Answer 1

when using autolayout you can set frame of the views (if the frame is calculated from super view's frame) in viewDidLayoutSubviews method or the other way I use is calling this method [view setTranslatesAutoresizingMaskIntoConstraints:YES]; and then [view setFrame:...]; . Hope this helps.

Answer 2

The position and size of subviews can be set when the UIViewController calls viewDidAppear but that causes the presentation to jump. Setting the position and size of a UITableView in viewDid/WillLayoutSubviews does not work.
