UIView addSubview auto layout not working

Question

I created a UIView programatically and add NSLayoutConstraint to it and it works and then add it as a subView of view controller\'s view. Right now I need to remove this vie

Answer 1

The problem is the sub view does not inherit the original view's size/frame, and therefore adds the view as if it was stuck in the Any+Any size of 600x600. My solution, is to set the frame of the original view, and then let iOS do the remainder of the work.

[self.myOtherView setFrame:self.view.frame];   //Replace frame size with already resized view
[self.myOtherView setNeedsLayout];  //Tell iOS to autolayout the new sub view
[self.addSubView:self.myOtherView];  //Add it
