FBWebDialogs没有显示 - 没有反应

Question

如果您有任何人可以帮助我使用这个Facebook SDK。我不知道发生了什么，问题是当点击facebook的按钮时没有显示任何内容 - FBWebDialog已经死了但＃34;当应用程序被激活时，Xcode中的内存管理/消费栏该操作后的额外内存（约22 MB）。我已经按照官方教程：https://developers.facebook.com/docs/ios/share并重新安装了facebook SDK，添加了AppID等内容。即便如此，我也没有帮助过。那有什么不对？

我正在使用iphone模拟器和ios 8和Xcode 6.0。大约2 mounths之前一切正常。到目前为止，应用程序中显示了弹出窗口。 任何有关这方面的帮助将不胜感激。

我的代码：

[FBLoginView class];

            FBLinkShareParams *params = [[FBLinkShareParams alloc] init];
            params.link = [NSURL URLWithString:@"https://developers.facebook.com/docs/ios/share/"];

            // If the Facebook app is installed and we can present the share dialog
            if ([FBDialogs canPresentShareDialogWithParams:params]) {
                // Present the share dialog
                [FBDialogs presentShareDialogWithLink:params.link
                                              handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {

来自Facebook网站的标准代码，但仍然没有反应。
