IOS error when I use Facebook SDK

Question

I have added FacebookSDK.framework into my project,

#import <FacebookSDK/FacebookSDK.h>

but I get this error: Use of undeclared identifier 'FBAppCall'

I am working about function LoginFB, please help me.

We need more code in order to help you. Where do you use the SDK's functions? Do you use the FBAppCall anywhere in your code? edit: according to the comment above this that's an Xcode problem, try following that solution, if it doesn't work come back with more code. — hfingler
I use FBAppCall into this methods: - (void)applicationDidBecomeActive:(UIApplication *)application { // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. [FBAppCall handleDidBecomeActive]; } — Võ Mai Trinh

Please check all below points -

Select Project and goto Build phase -> Link binary with Libraries and select FacebookSDK.framework
Goto your viewcontroller and import - #import and #import

Please delete existing added FacebookSDK.framework before doing the above step.
