The FBAppCall object is used to encapsulate state when the app performs an action that requires switching over to the native Facebook app, or when the app receives an App Link.
- Each FBAppCall instance will have a unique ID
- This object is passed into an FBAppCallHandler for context
- dialogData will be present if this AppCall is for a Native Dialog
- appLinkData will be present if this AppCall is for an App Link
- accessTokenData will be present if this AppCall contains an access token.

| パラメーター | 説明 |
|---|---|
url | The url. |
+ (FBAppCall *) appCallFromURL:(NSURL *)url;This is typically used for App Link URLs.
FBAppCall.hhandleDidBecomeActiveCall this method when the application's applicationDidBecomeActive: is invoked. This ensures proper state management of any pending FBAppCalls or pending login flow for the FBSession.activeSession. If any pending FBAppCalls are found, their registered callbacks will be invoked with appropriate state
+ (void) handleDidBecomeActive;FBAppCall.hhandleDidBecomeActiveWithSession:Call this method when the application's applicationDidBecomeActive: is invoked. This ensures proper state management of any pending FBAppCalls or a pending open for the passed in FBSession. If any pending FBAppCalls are found, their registered callbacks will be invoked with appropriate state
| パラメーター | 説明 |
|---|---|
session | Session that is currently being used. Any pending calls to open will be cancelled. If no session is provided, then the activeSession (if present) is used. |
+ (void) handleDidBecomeActiveWithSession:(FBSession *)session;FBAppCall.hhandleOpenURL:sourceApplication:Call this method from the [UIApplicationDelegate application:openURL:sourceApplication:annotation:] method of the AppDelegate for your app. It should be invoked for the proper processing of responses during interaction with the native Facebook app or as part of SSO authorization flow.
| パラメーター | 説明 |
|---|---|
url | The URL as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
sourceApplication | The sourceApplication as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
+ (BOOL) handleOpenURL: | (NSURL *)url |
sourceApplication: | (NSString *)sourceApplication; |
FBAppCall.hhandleOpenURL:sourceApplication:fallbackHandler:Call this method from the [UIApplicationDelegate application:openURL:sourceApplication:annotation:] method of the AppDelegate for your app. It should be invoked for the proper processing of responses during interaction with the native Facebook app or as part of SSO authorization flow.
| パラメーター | 説明 |
|---|---|
url | The URL as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
sourceApplication | The sourceApplication as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
handler | Optional handler that gives the app the opportunity to do some further processing on urls that the SDK could not completely process. A fallback handler is not a requirement for such a url to be considered handled. The fallback handler, if specified, is only ever called sychronously, before the method returns. |
+ (BOOL) handleOpenURL: | (NSURL *)url |

FBAppCall.hhandleOpenURL:sourceApplication:withSession:Call this method from the [UIApplicationDelegate application:openURL:sourceApplication:annotation:] method of the AppDelegate for your app. It should be invoked for the proper processing of responses during interaction with the native Facebook app or as part of SSO authorization flow.
| パラメーター | 説明 |
|---|---|
url | The URL as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
sourceApplication | The sourceApplication as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |

FBAppCall.hopenDeferredAppLink:Call this method from the main thread to fetch deferred applink data. This may require a network round trip. If successful, [+UIApplication openURL:] is invoked with the link data. Otherwise, the fallbackHandler will be dispatched to the main thread.
| パラメーター | 説明 |
|---|---|
fallbackHandler | The handler to be invoked if applink data could not be opened. |
+ (void) openDeferredAppLink:(FBAppLinkFallbackHandler)fallbackHandler;The fallbackHandler may contain an NSError instance to capture any errors. In the common case where there simply was no app link data, the NSError instance will be nil.
This method should only be called from a location that occurs after any launching URL has been processed (e.g., you should call this method from your application delegate's applicationDidBecomeActive:) to avoid duplicate invocations of openURL:.
If you must call this from the delegate's didFinishLaunchingWithOptions: you should only do so if the application is not being launched by a URL. For example,
if (launchOptions[UIApplicationLaunchOptionsURLKey] == nil) { [FBAppCall openDeferredAppLink:^(NSError *error) { // .... } }
FBAppCall.hisEqualToAppCall:Compares the receiving FBAppCall to the passed in FBAppCall
| パラメーター | 説明 |
|---|---|
appCall | The other FBAppCall to compare to. |
- (BOOL) isEqualToAppCall:(FBAppCall *)appCall;FBAppCall.hFBAppCallHandlerA block that is passed to performAppCall to register for a callback with the results of that AppCall
typedef void (^FBAppCallHandler)( FBAppCall *call); Pass a block of this type when calling performAppCall. This will be called on the UI thread, once the AppCall completes.
