dyld: Library not loaded: @rpath with iOS8

问题:

I'm creating an iOS framework with Xcode6 and iOS8. When I link this with an iOS app and try running it on the device I get this error

dyld: Library not loaded: @rpath/FrameworkName.framework/FrameworkName
  Referenced from: /private/var/mobile/Containers/Bundle/Application/0F2C2461-A68B-4ABA-A604-B88E6E9D1BB1/AppName.app/AppName
  Reason: image not found

The 'Runpath Search Paths' build setting for the framework is set by default to

'@executable_path/Frameworks', '@loader_path/Frameworks'

I could not find any documentation related to this. This was something new introduced with Xcode6 and I would expect it to just work by simply including the framework into any app that needs it.

回答1:

To make this work

1. In the framework project settings change the install directory from '/Library/Frameworks' to '@executable_path/../Frameworks'

2. In the project that includes this framework, add a copy files phase and copy this framework to the 'Frameworks' folder. Once you do this ensure that this framework is listed under the 'Embedded Binaries' section.

Issue resolved using this answer. According to @vladof81:

In the target's General tab, there is an Embedded Binaries field. When you add the framework there the crash is resolved.

Reference is here on Apple Developer Forums.

回答3:

I was getting this error on a library installed through CocoaPods. Cleaning the build folder (cmd + option + shift + k) and then doing a clean (cmd + shift + k) was what ended up resolving this issue for me.

回答4:

Check if you can find framework in context under :

Build Phases > Embed Frameworks >

If not just add that framework in "Embed Frameworks" after adding that framework in your project directory's "Frameworks" section.

回答5:

If you are using Carthage

Run carthage update on terminal

Go to Project Settings -> Build Phases -> Carthage Copy Frameworks

Add line in Inputs files: $(SRCROOT)/Carthage/Build/iOS/YOURLIBRARY.framework

Add this line to Output files: $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/YOURLIBRARY.framework

For me it was because of the SSL issue, I had set my developer, distribution certificates on my Mac(Keychain) to 'Always Trust' for one of my other project. I had to change them back to 'Use System Defaults'. it was working for me then!!

回答7:

Made the library which shows not loaded changed from required to optional in Linked binaries and frameworks. It is working perfectly now

回答8:

In addition to the above solutions, recheck the paths of frameworks included in your application under

Build Settings --> Search Paths --> Framework Search Paths

I also had same kind of problem where I was not able to launch the app & app was crashing with above message :

dyld: Library not loaded: @rpath/FrameworkName.framework/FrameworkName Referenced from: /private/var/mobile/Containers/Bundle/Application/xxxxxxxxxxxxxxxxxxx

Here is my approach that helped me to resolve this error:

1.Please delete your app from device, Clean the build and and rebuild and run on the device.

2.If above steps does not help you, then please check for below settings :
From "TARGET">"Build Settings">"Runpath Search Paths" & then check for values "$(inherited)" & "@executable_path/Frameworks", Feel free to add incase they don't exist.

Build your app and run it on device

回答10:

When non of those solution works:

1. (Optional) Get a clear knowledge from here on different search path type
2. Make sure that your .framework file paths are added in Build Settings -> Framework Search Paths. You can keep all framework files somewhere in App/libs/ and add this folder and enable recursively.
3. Make sure that your .a files paths are added in Build Settings -> Library Search Paths.

I installed third party libraries using Cocoapods. Got the same error, tried everything but finally realised I havent had use_frameworks! in my pod file.

So removed the currently installed library, added use_frameworks! line in pod file, reinstalled the libraries and all worked for me.

Here is my approach that helped me to resolve this error:

1. From General Tab

Frameworks, Libraries, and Embedded Content

• add the framework and make sure to make it Embed & Sign

2. From Build Phases

Dependences

• add the framework to it
