Unable to use iOS framework which is internally using .xib file

Question

I am trying to make a universal framework, for iOS by following steps specified in this URL: Universal-framework-iOS

I have a viewController class within, that frame

The simplest way is to use [NSBundle bundleForClass:[self class]] to get the NSBundle instance of your framework. This won't enable the ability to get the framework's NSBundle instance by its Bundle ID but that isn't usually necessary.

The issue with your code is the initWithNibName:@"Name" bundle:nil gets a file named Name.xib in the given bundle. Since bundle is nil, it looks in the host app's bundle, not your framework.

The corrected code for the OP's issue is this:

/*** Part of implementation of ViewControllerWithinFramework class, which is inside the framework ***/

- (id)initWithTitle:(NSString *)aTitle
{
   NSBundle *bundle = [NSBundle bundleForClass:[self class]];
   self = [super initWithNibName:@"ViewControllerWithinFramework" bundle:bundle];

   // ... 

   return self;
}

The only thing changed is giving the correct bundle instance.
