Afnetworking: [UIApplication sharedApplication] is unavailable in keyboard extension [iOS8]

[GuriK]

I tried to use AFNetworking with iOS8 keyboard extensions and got this error

'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.
AFURLConnectionOperation.m#L220
AFURLConnectionOperation.m#L300

Any ideas ?

App Extensions

When using AFNetworking in an App Extension, #define AF_APP_EXTENSIONS to avoid using unavailable APIs.

Thanks for reporting this, @GuriK!

[canaksoy]

how can I define it? any example?
I am using AFNetworking in my app and also in my today extension

[lexar]

Hi, I would also like to know where to define this. Xcode 6 has no prefix file in a new project, should I define one? I placed #define AF_APP_EXTENSIONS in the headers and implementations of the extension classes and where I actually use AFNetworking, a shared instance which is not even used by the extension at the moment, but I can't get that compiler error away.
So what would be the appropriate place to put the define?
EDIT: Putting the define right before setShouldExecuteAsBackgroundTaskWithExpirationHandler: lets me compile of course :)
But I would like to know the appropriate way to use the directive...

@lexar , there is a place you can put it: in Project Navigator, select your project -> select your extension target on the left -> Build Settings -> search for "Preprocessor Macros" and add AF_APP_EXTENSIONS to the list.

I still see additional errors in AFNetworkActivityIndicatorManager.m

'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:[self isNetworkActivityIndicatorVisible]];

and UIAlertView+AFNetworking

'initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles:' is unavailable: not available on iOS (App Extension) - Use UIAlertController instead.

This is how I fixed (was wary of forking & making PR, there are already way too many forks of this project!):

@jpmhouston I'm running into the same issue. I think that submitting your PR would be great!

[jpmhouston]

@bejar37 sorry, it turns out our share extension doesn't need AFNetworking after all so I'm busy on other tasks now and I won't be creating this PR. Feel free to use the patch above and do that yourself though.

[aelam]

this can really fix issues

#if !(defined(__has_feature) && __has_feature(attribute_availability_app_extension))
  //Not in the extension
#else
  //In extension
#end

[ruslanskorb]

Hey there!

To resolve this problem in another way, you can use my category and simple condition:

UIApplication *application = [UIApplication rsk_sharedApplication];
if (application) {
    // call any method of the app instance
}

[aelam]

I think it can have a much simplified version

@aelam I'll be glad to see a simplified version.

[justinmpier]

In case someone's wondering (I was) where to put the #define AF_APP_EXTENSIONS so that it only applies for the extension target if also your container app uses the library, these steps worked for me: http://stackoverflow.com/a/29335471/3949162

[pilot34]

What is the right way to define AF_APP_EXTENSIONS, when using cocoapods?
To avoid overwriting after pod install.

[jacinzhang]

 为什么定义了AF_APP_EXTENSIONS还是提示同样地错误信息。

[jacinzhang]

我使用了cocoapods来管理AFNetworking，macro里面加了AF_APP_EXTENSIONS=1,判断条件加了!defined(AF_APP_EXTENSIONS),还是报错,
Any ideas?

[aelam]

@ZHANGMRXIN

Add this to your podfile. remember to replace the target name

post_install do |installer_representation|
    installer_representation.project.targets.each do |target|
        if target.name == "Pods-YOU_EXTENSION_TARGET-AFNetworking"
            target.build_configurations.each do |config|
                    config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', 'AF_APP_EXTENSIONS=1']
            end
        end
    end
end

[vani2]

@aelam not work for me.
This works: config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'

[aelam]

Wrong target name? You tell me ^

@aelam The __has_feature(attribute_availability_app_extension) way doesn't work. The macro indicates the compiler has the support for compiling application extension, not compiling for application extension.

[georgbachmann]

any idea how this works with cocoapods 0.38.2? Cause for me it isn't working :(

[jeffremer]

I also can't build with any combination of workarounds and hacks, using cocoapods 0.38.2 and the latest AFNetworking (2.6.0, upgrading from 2.5.4). I've tried the post_install hooks mentioned above and on Stack Overflow, as well as editing individual prefix headers for the today widget target and AFNetworking.

@jeffremer @georgbachmann Some things got updated so check this answer if you still don't have it working http://stackoverflow.com/a/31992480/896334

[msmobileapps]

@thisiscrazy4 I tried everything here and only this one ^ worked :) :+1:
thanks
