一个UIViewController中有多个UIView

Question

I am developing a iPad App. There is one UIViewController which should show all relevant information. Inside this VC there are 2 UIViews: The first UIView on the first half of the Screen shows a Image and some text. The second View on the bottom half of the screen should display some stuff like a map or a image gallery depending on the button that was pressed in the center of the screen.

My first try was to load for example a GalleyViewController and then get his View and add this as a Subview to my BottonView like this:

-(void)galleryButtonPressedInCenter{
    GalleryViewController * gal = [[GalleryViewController alloc] initWithNibName:@"GalleryViewController" bundle:nil];
    [gal.view setFrame:CGRectMake(0,0,620,300)];
    [self.bottomView addSubview: gal.view];

But this will crash my app if I touch the View with my finger.

To show what I want to achieve: On the last Screenshot ( http://itunes.apple.com/de/app/ebookers-hotels-furs-ipad/id465464927?mt=8 ) you can see that in this App there is a ImageView and some other Stuff in the upper part and in the lower part there are multiple Views that are switched depending on the button that was pressed.

Answer 1

Make an empty fullscreen view. then add your subviews to that view.

  ViewController
      -UIView  (your new umbrella view)
          -UIView  (subView 1)
          -UIView (subview 2)

I don't think I've seen it documented in the helpfiles, but I'm finding that each "ViewController" can only have one UIView directly attached. I'm kinda new at this though, try it anyway :)
