When you were dragging in your label and your button to this view, you were adding them as subviews.
By doing this programmatically you can see what goes into adding a subview. You’dneed to pass in a frame to the alloc:initWithFrame: method, which is found onmost UIView subclasses:
CGRect frame = CGRectMake(0,0,100,20);UILabel *label = [[UILabel alloc] initWithFrame:frame];// To add this label to its parent view within a view controller, all you have to// do is use the addSubView: function.[self.view addSubView:label];// Retrieving the frame, making a change to its size or origin, and then // resetting its frame propertyCGRect frame = label.frame;frame.origin.x = 10;frame.size.width = 200;[label setFrame:frame];
