Question

I’ve been working on getting “custom skinnable” interfaces working for my iOS app by bundling up xibs and downloading bundles, and loading the xibs in those bundles.

I have followed the very useful instructions here to get it almost working.

loading NSBundle files on iOS

I have the bundle downloading, and unzipping and can see the xib file. I have not used any of the TestViewController code in the example, but am instead doing this when creating the view controller using the just downloaded xib:

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"gg.bundle"];
    NSBundle *bundle = [NSBundle bundleWithPath:filePath];

    if ( !bundle )
    {
        NSLog(@"Error getting bundle");
    }

    MyViewController *vc = [MyViewController new];
    [vc initWithNibName:@"CustomDownloadedXib" bundle:bundle];

When I go to push this view controller onto my stack, I get this error:

*** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Could not load NIB in bundle: ‘NSBundle (not yet loaded)’ with name ‘CustomDownloadedXib”

The issue seems to be that my bundle is “not yet loaded.” I tried forcing my bundle to load by calling:

[bundle load]

but that doesn’t help.

Is my approach here incorrect? This seems like the intuitive way to do it.

Thanks in advance!

Following the instructions here works:

I was just creating the bundle incorrectly!

You need to create the bundle in Xcode though because if you don’t, it won’t be loaded. To create, Add a New Target to your project, choose Framework & Library -> Bundle, and link to Core Foundation. Then add the xibs you want to upload to the web to the target. Build target, reveal it in Finder, compress, and upload!
