ios - PFFacebookUtil 超时错误

Question

我遇到了此处提到的类似问题:https://www.parse.com/questions/error-when-trying-to-reauthorise-facebook-user

当我的应用程序启动时，如果用户已经登录，它会尝试从 Facebook 获取用户的个人资料图片:

- (void)getFacebookIdAndProfileImageWithSuccess:(void(^)(NSDictionary *))success {
    // Send request to Facebook to retrieve profile information
    FBRequest *request = [FBRequest requestForMe];
    [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        if (error)
            return;

        // Result is a dictionary of user information
        NSMutableDictionary *userData = (NSMutableDictionary *)result;

        NSString *facebookId = userData[@"id"];
        [userData setObject:facebookId forKey:@"facebookId"];

        // Retrieve the user profile image
        NSURL *imageUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@/%@/picture?height=55&width=55", BaseApiUrl, facebookId]];
        UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:imageUrl]];
        [userData setObject:image forKey:@"image"];
        [userData setObject:[imageUrl absoluteString] forKey:@"imageUrl"];

        success([NSDictionary dictionaryWithDictionary:userData]);
    }];
}

好吧，请求返回需要很长时间，当它返回时会报告错误:

"Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x146aa790 {com.facebook.sdk:ErrorInnerErrorKey=Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x146a1710 {NSErrorFailingURLStringKey=https://graph.facebook.com/,

我删除了我的应用程序并重新安装了它。这解决了这个问题。问题可能是在我开始收到此错误之前，我正在尝试解决我的应用程序遇到的另一个与 Facebook 相关的问题。我尝试过的其中一件事是删除我的 Facebook 帐户设置 > Facebook。也许这与此错误有关，我不确定。
