使用Facebook SDK 4.15.1在iOS 10上使用Facebook SDK登录,分享和喜欢时获取空白页面

Question

使用FBSDKLoginKit,FBSDKShareKit登录,共享链接和我的应用程序中的链接时,我收到此错误.我使用FBSDKLoginButton登录

 @property (nonatomic, strong) IBOutlet FBSDKLoginButton *loginButton;

- (void)viewDidLoad {
    [super viewDidLoad];

    self.loginButton.publishPermissions = @[@"publish_actions"];
}

使用FBSDKShareKit分享:

- (FBSDKShareDialog *)getShareDialogWithContentURL:(FBSDKShareLinkContent *)content
{
    FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
    shareDialog.shareContent = content;
    return shareDialog;
}

- (IBAction)ShareAppOnFB:(UIButton *)sender {

        FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
        FBSDKShareDialog *facebookShareDialog = [self getShareDialogWithContentURL:content];

        if ([facebookShareDialog canShow]) {
            [FBSDKShareDialog showFromViewController:self.parentViewController
                                         withContent:content
                                            delegate:self];
        }

}

使用FBSDKShareKit喜欢:

FBSDKLikeButton *like = [[FBSDKLikeButton alloc] init];
like.objectID = @"";
like.frame = CGRectOffset(like.frame, 50, 100);
[self.view addSubview:like];

在iOS 9和iOS 8上一切正常,但是当我升级到Xcode 8并在iOS 10上运行时,当点击Login,Share和Like Button时我立即得到一个空白页面,之后没有任何反应.我尝试升级到Facebook SDK 4.15.1,但没有更好的,这个bug仍然会发生.任何人都知道如何修复iOS 10上的这个错误？

FB SDK使用SFSafariViewController,显然在iOS 10中它只能从根视图控制器中呈现.解决方案是创建一个新的UIWindow实例,添加一个普通的UIViewController作为根视图控制器,并使用这个新的UIViewController调用FB SDK:

UIViewController* socialVC = [[UIViewController alloc] init];
// window instance needs to be retained
self.socialWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.socialWindow.rootViewController = socialVC;
// show new window in top of every other UIs
self.socialWindow.windowLevel = UIWindowLevelStatusBar + 10;
[self.socialWindow makeKeyAndVisible];

// show FB Share Dialog
[FBSDKShareDialog showFromViewController:socialVC withContent:content delegate:self];

调用FB SDK的委托时,不要忘记隐藏窗口:

self.socialWindow.hidden = YES;
