我正在开发一个需要在Facebook 上分享视频的应用程序。当我尝试 developer.facebook.com 寻求解决方案时，我发现使用图形 api 在 ios 中上传视频。它通过图形 API 共享视频。图形 API 可以工作iOS 6吗？请建议。如果有，还请提供任何示例代码。
提前致谢。

试试这个我使用 Facebook SDK 3.1 https://developers.facebook.com/ios/
.h 文件
#import <FacebookSDK/FacebookSDK.h>
extern NSString *const SCSessionStateChangedNotificationCamera;
.m 文件
NSString *const SCSessionStateChangedNotificationCamera = @"com.facebook.Scrumptious:SCSessionStateChangedNotification";
-(IBAction)btnFacebookShareClick:(id)sender {
if (![self openSessionWithAllowLoginUI:YES]) {
[self showLoginView];
}
}
#pragma mark -
#pragma mark - Facebook Method
- (void) performPublishAction:(void (^)(void)) action {
if ([FBSession.activeSession.permissions indexOfObject:@"publish_actions"] == NSNotFound) {
[FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
}
}];
}
else {
action();
}
}
