FBSDKShareAPI

这个类有新版本。查看最新版本。

A utility class for sharing through the graph API. Using this class requires an access token in [FBSDKAccessToken currentAccessToken] that has been granted the "publish_actions" permission.

Discussion:

FBSDKShareAPI network requests are scheduled on the current run loop in the default run loop mode (like NSURLConnection). If you want to use FBSDKShareAPI in a background thread, you must manage the run loop yourself.

Conforms to:	`FBSDKSharing`
Inherits from:	`NSObject`

类方法

shareWithContent:delegate:

Convenience method to build up a share API with content and a delegate.

参数	描述
`content`	The content to be shared.
`delegate`	The receiver's delegate.

+ (instancetype)

`shareWithContent:`	`(id<FBSDKSharingContent>)content`
`delegate:`	`(id<FBSDKSharingDelegate>)delegate;`

声明语言： FBSDKShareAPI.h

实例方法

canShare

A Boolean value that indicates whether the receiver can send the share.

- (BOOL) canShare;

Discussion:

May return NO if the appropriate Facebook app is not installed and is required or an access token is required but not available. This method does not validate the content on the receiver, so this can be checked before building up the content.

声明语言： FBSDKShareAPI.h

createOpenGraphObject:

Creates an User Owned Open Graph object without an action.

参数	描述
`openGraphObject`	The open graph object to create.

- (BOOL) createOpenGraphObject:(FBSDKShareOpenGraphObject *)openGraphObject;

Discussion:

Use this method to create an object alone, when an action is not going to be posted with the object. If the object will be used within an action, just put the object in the action and share that as the shareContent and the object will be created in the process. The delegate will be messaged with the results.
