Using Storyboards and Image assets in Custom Cocoapods

Question

I'm trying to modularize a large iOS project (being developed in Swift) using cocoa pods. The idea is to create "sub apps" complete with storyboards and assets which could be integrated into the main project.

I'm having troubles using storyboards in such a scenario. The issue is similar to (I think): https://github.com/CocoaPods/CocoaPods/issues/2597

Here is the .podspec of the module I'm trying to convert into a pod:

Pod::Spec.new do |spec|
  spec.name = 'GlycoAppMenuModule'
  spec.version = '0.0.8'
  spec.license = { :type => 'MIT', :file => 'LICENSE' }
  spec.homepage = 'https://google.com'
  spec.platform = :ios, "8.0"
  spec.authors = { 'Abdulla Contractor' => '[email protected]' }
  spec.summary = 'Views for menu page'
  spec.source = { :git => 'https://github.com/Holmusk/GlycoAppMenuModule.git', :tag => '0.0.8' }
  spec.source_files = 'GlycoAppMenuModule/*'
  spec.resource_bundles = {
    'resources' => ['GlycoAppMenuModule/**/*.{lproj,storyboard}']}
  # spec.framework = 'Foundation'
end

and here is the code I use to attempt to use the storyboard

let bundlePath = NSBundle(forClass: GANavigationMenuViewController.self).pathForResource("resources", ofType: "bundle")
        let bundle = NSBundle(path: bundlePath!)
        let storyboard: UIStoryboard = UIStoryboard(name: "Menu", bundle: bundle)
        let vc = storyboard.instantiateInitialViewController() as! UIViewController
        self.presentViewController(vc, animated: false, completion: nil)

this is the error I get

Any idea what I may be missing?

Answer 1

I had the same problem and I solved it.

In your .podspec the ONLY resource tag you need is:

s.resources = "MMA_Piece/**/*.{png,jpeg,jpg,storyboard,xib,xcassets}"

Now you might be asking: "Of course I have already tried this but it didn't work? Why should it work now?"

Well let me tell you :D

Make sure that EVERY resource you want to have included in your custom CocoaPod is inside your bottom level project directory. In my case (MMA_Piece project) this is the following folder (the selected one):

Done! If you use the pod in another project by using 'pod install' your resources will have come with it like so:

IMPORTANT: If you want to use the resource in your other project, say "MainProject", you will ALWAYS need to specify the bundle! Or "MainProject" won't be able to find the resource!

Hope this helps you out!
