Loading resource_bundle error in cocoapods

问题

I am trying to make my own cocoapods, I used images. When I follow the tutorial, I get an error.

.podspec

  s.resource_bundles = {
    'SSSlidingSelector' => ['SSSlidingSelector/Assets/*.xcassets']
  }

Class/SlidingSelector.m

- (UIImage *)getImageWithName:(NSString *)imageName {
    NSBundle *bundle = [NSBundle bundleForClass:[self class]];
    NSURL *url = [bundle URLForResource:@"SSSlidingSelector" withExtension:@"bundle"];
    NSBundle *targetBundle = [NSBundle bundleWithURL:url];
    UIImage *image = [UIImage imageNamed:imageName
                                inBundle:targetBundle
           compatibleWithTraitCollection:nil];
    return image;
}

error

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSBundle initWithURL:]: nil URL argument'

回答1:

Nothing wrong with your code.

Cocoapods on version 1.0.1 supports Assets Catalogs. Please check if yours isn't below it running pod --version in Terminal.

If a new pod install does not solved, there is an issue with the xCode New Build System on Assets Catalogs (as mentioned Here) that could be your problem.

You can change the Build System on File > Workspace Settings... > Build System. Try setting it to Legacy Build System.

    NSBundle *bundle = [NSBundle bundleForClass:[self class]];
    UIImage *image = [UIImage imageNamed:imageName
                                inBundle:bundle
           compatibleWithTraitCollection:nil];
    return image;
}
