Load image from CocoaPods resource bundle

Question

I am creating a private library that includes resources that are referenced by components in the library. The library is shared with apps using CocoaPods. In the .podspec for

Answer 1

For example Paramount

podspec

s.resource_bundle = {
    'Paramount' => ['Sources/Paramount.bundle/*.png']
}

swift

public extension UIImage {
  static func make(name: String) -> UIImage? {
    let bundle = NSBundle(forClass: Paramount.Toolbar.self)
    return UIImage(named: "Paramount.bundle/\(name)", inBundle: bundle, compatibleWithTraitCollection: nil)
  }
}

Here Paramount.Toolbar.self can be any class in that framework

Answer 2

I made a pod that can locate the resource bundles in pods. I hope it will end the "CocoaPods resource bundle" problem once and for all.

Answer 3

This turns out to be a problem with asset catalogs, not CocoaPods or bundles. Moving the images out of the asset catalog solved the problem. It looks like Apple doesn't support asset catalogs in secondary resource bundles. Pity.

Answer 4

The obvious solution that wasn’t listed anywhere is using the Cocoapods generated bundle (which the folder actually doesn’t exist) as a NSBundle:

it worked for me!!

Answer 5

As for me, I had to add the "s.resources" into the .podspec. Before this was missing.

Only the s.resource_bundles were set this way: 'BPPicker/Assets/.', changed it to 'BPPicker/Assets/*' as well.

#
# Be sure to run `pod lib lint BPPicker.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a # are optional, but their use is encouraged
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#

Pod::Spec.new do |s|
  s.name             = 'BPPicker'
  s.version          = '0.1.11'
  s.summary          = 'This is the imito Body Part Picker.'

# This description is used to generate tags and improve search results.
#   * Think: What does it do? Why did you write it? What is the focus?
#   * Try to keep it short, snappy and to the point.
#   * Write the description between the DESC delimiters below.
#   * Finally, don't worry about the indent, CocoaPods strips it!

  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://bitbucket.org/imito/bppicker'
  # s.screenshots     = 'www.example.com/screenshots_1', 'www.example.com/screenshots_2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'Ievgen Naloiko' => 'naloiko@gmail.com' }
  s.source           = { :git => 'https://ievgen_naloiko@bitbucket.org/imito/bppicker.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'

  s.ios.deployment_target = '9.0'

  s.source_files = 'BPPicker/Classes/**/*'

  s.resource_bundles = {
    'BPPicker' => ['BPPicker/Assets/*']
  }
    s.resources = "BPPicker/**/*.{png,json}"

    s.frameworks = 'UIKit'
    s.dependency 'ObjectMapper'
end

In your pod file: images are in .xcassets so it can be easily organized with 1x, 2x, 3x

s.resources = 'PodName/Assets/**'

Usage: Swift

let bundle = Bundle(for: ClassThatWillUseTheImage.self)
let image = UIImage(named: "close", in: bundle, with: .none)

Usage: Objective-C

NSBundle *bundle = [NSBundle bundleForClass:[self class]];
UIImage *image = [UIImage imageNamed:@"close" inBundle:bundle withConfiguration:nil];

Tested in Version 11.4 (11E146) iOS 13.0+

Using #imageLiteral(resourceName: "close") does not work however, it shows the image being read but will throw and error.
