iOS – a NIB's view used across storyboards (for design & animation logic)

I have a iOS 5 project nearly completed, but there’s one View missing everywhere which is the same. It’s an alternative to the standard NavigationBar, you can go “back” in the navigation hierarchy with a swipe and it’s animating nicely.

Ok, because it’s hard to do the layout by code I created the empty IB document (HeaderView.xib) where I have a view containing subview and etc.
I had the animation code before so I just created a UIView subclass (“HRAnimationView”) (and wrote the name of it in the xib’s inspectors “Custom Class” field, also hooked up the subviews to outlets) with a method:

  • Swift - Assign a NIB to self in class
  • Marking some XIB/Storyboard strings as not localizable
  • Not sure why UIView is being nudged up by around 10px
  • Since XCode 6.3 -> Nib could not be loaded
  • How to close a window programmatically in Cocoa Mac?
  • Xcode crashes when I open a specific XIB file
  • - (void)loadAnimation {…}

    and a second one (this is the delegate-method for finished animations):

    - (void)animationDidStop:(NSString*)animationID finished:(NSNumber*)finished context:(void*)context {}

    …this is where all the animation stuff happens and calling itself over and over till it’s finished…

    In the storyboard I have a subview with exact the same dimensions (and the outlet for it) and wanted to load the XIB (in the viewDidLoad-method of the corresponding controller) with:

    NSArray *bundle = [[NSBundle mainBundle] loadNibNamed:@"HeaderView" owner:self options:nil];
    HRAnimationView *view;
    for (id object in bundle) {        
        if ([object isKindOfClass:[UIView class]])
            view = (HRAnimationView *)object;
    self.headerView = view;
    [self.view setNeedsDisplay];
    [view loadAnimation];

    BUT the headerView is EMTPY!! (also UIView *view didn’t worked, nor owner:self.headerView)

    …the Log just gives me:

    <HRAnimationView: 0x3f1890; frame = (0 0; 240 49); autoresize = RM+BM; layer = <CALayer: 0x3f18d0>>

    WHAT IS the problem?? There’s also no compilation failure!

    I don’t get it, why is the xib TOTALLY worthless in my case?!

    NSArray *bundle = [[NSBundle mainBundle] loadNibNamed:@”HeaderView” owner:self options:nil];

    after the above statement… try adding this

    [self.headerView = [bundle objectAtIndex:0]

    this should solve the problem


    I created a new ViewController and checked the “create with xib” box and deleted the view of the xib and copy&pasted the already set up view in there and in the ViewController I put the animation code in viewDidLoad.

    Then loaded the hole thing in the viewDidLoad-method of each storyboard ViewController with:

    UIViewController *ctrl = [[UIViewController alloc] initwithNibNamed:@"HeaderView"];
    [self.headerView addSubview:ctrl.view]

    (headerView is a IBOutlet to a view in every Storyboard so, that’s basically the only thing to setup, NICE!)

    1. another possibility would be:
      Add subview using storyboard without external xib
    2. or:

    Looks like a Xib is useless without a corresponding ViewController, but should (strange.. whatever).
    But thanks for your responses, hope someone now can find this if he/she has the same problem!
