Can't import dependency installed with Cocoapods

问题

I've installed FBSDK with Cocoapods but can't import it in my AppDelegate.swift file for some reason. The FBSDK kit appears in my Xcode project so I feel like it should be working.

I'm not an iOS developer by any means, I'm just trying to write a simple native plugin for Flutter SDK. Anyone an idea?

--Here is what the pod file looks like--

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

if ENV['FLUTTER_FRAMEWORK_DIR'] == nil
  abort('Please set FLUTTER_FRAMEWORK_DIR to the directory containing Flutter.framework')
end

target 'Runner' do
  use_frameworks!

  # Pods for Runner
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
pod 'FBSDKShareKit'

  # Flutter Pods
  pod 'Flutter', :path => ENV['FLUTTER_FRAMEWORK_DIR']

  if File.exists? '../.flutter-plugins'
    flutter_root = File.expand_path('..')
    File.foreach('../.flutter-plugins') { |line|
      plugin = line.split(pattern='=')
      if plugin.length == 2
        name = plugin[0].strip()
        path = plugin[1].strip()
        resolved_path = File.expand_path("#{path}/ios", flutter_root)
        pod name, :path => resolved_path
      else
        puts "Invalid plugin specification: #{line}"
      end
    }
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

---EDIT---

I''m getting the following error atm: FBSDKCoreKit.framework: No such file or directory.When I open the Frameworks folder in xCode, all file names are in red: But that exact folder in Finder is empty. So I guess that's why the error is showing. The question is how to fix this...

This is what my embedded binaries and linked frameworks and libraries look like in the project:

回答1:

Select your Project Target
Go to Build Settings.
Search for Header Search Paths.
Add this value $(SRCROOT)/Pods with recursive, then Xcode will resolve the path for you.

回答2:

I'll naively suppose you don't have use_frameworks! in you Podfile. If that's true, than you have two ways to go from here:

In your Runner-Bridging-Header.h add #import <FBSDKCoreKit/FBSDKCoreKit.h>, remove import FBSDKCoreKit from AppDelegate.swift and just continue writing the code.
Add use_frameworks! to your Podfile and run pod install again. That might bring some other issues, but if that works, than I'd suggest it.

回答3:

Are you opening the .xcodeproj or the .xcworkspace? Make sure it is the workspace whenever you install a cocoapod

回答4:

If you use cocoapods, it should have generated a *.xcworkspace file for you. Open this file instead so your project can see the FBSDK installed and has reference to it.

回答5:

Why not simply use the Swift pods?-

pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'

and then import as normal, like-

import FBSDKLoginKit
import FacebookLogin

Once done, do a clean and build (command/⌘ + Shift + K) and Build (command/⌘ + B). Make sure you are using the .xcworkspace file to open the project.

More info on Swift FBSDK here.

Once you use the Swift pods, you should see these Frameworks in your project.

If you still continue to see the error then "Clean the build folder" using command + shift + alt + K.

回答6:

When you install your pods, you must build your application first. Then your imports stop showing errors.

回答7:

Start by cleaning your project using Command + Shift + K then close the project and delete the pods folder and the pod.lock file and your .xcworkspace file. Then run pod install and see if that fixes the issue.

回答8:

First Clean your project directory. And add $(inherited) in framework search path in Build settings.

回答9:

As importing the FBSDKCoreKit.framework etc. will be performed in the [CP] Embed Pods Frameworks build phase when using CocoaPods, you should remove the references to these frameworks in the Embed Frameworks build phase.

CocoaPods will not create those references, I assume you have tried other ways of importing the Facebooks frameworks, and these link have been created in the process. You can also delete the references to the Facebook frameworks in the Frameworks Folder of you App-Project (the ones in your screenshot written in red, not the ones in the Pods-Project!), but keep the Pods_Runner.framework there.

From what I can tell, your Linked Frameworks and Libraries section looks valid.

If it still doesn't work, I'd advise you to create a new Xcode Project with an empty Podfile, and only include the Facebook frameworks via CocoaPods. Importing the Facebook-SDK in the AppDelegate should work then, otherwise I can share a sample project with you. Then you should check your build setting and build phases, maybe something is wrong there. If you still can't figure out the problem, you will probably need to re-create you xcode-project and import all your files again.

Without a sample Project that reproduces the error, that's the best advise I can give.

Good Luck! :)

回答10:

The above solutions for Header Search Path should work. If you are too lazy to go there. Copy podfile content, remove all pods, pod install, then revert your podfile, pod install again.... Should work ;-)
