iOS无法在Facebook上发布，未记录任何错误

我正在尝试使用他们iOS游戏教程中的代码与Facebook共享。对话框弹出，我指定的图像和文本出现，但当我点击“发送”时，加载栏出现，没有加载，然后我被重定向到我的应用程序。控制台上不会打印任何错误，应用程序也不会崩溃

当我在Facebook上查看消息是否已发布时，我得到以下信息：

“哎呀，出现了问题。发布您的状态时出现问题。我们已记录了错误，将对此进行调查。”

我在以前的应用程序中使用过这段代码，它运行得非常好。我已经在plist中更新了Facebook ID、Facebook显示名和URL方案

代码如下：

FacebookHandler类（源自Facebook教程）

我的电话

#import "FacebookHandler.h"

@implementation FacebookHandler

+ (void) Facebook_CreateNewSession
{
    // initialize Facebook
    FBSession* session = [[FBSession alloc] init];
    [FBSession setActiveSession: session];
}

+ (void) Facebook_Login
{
    NSArray *permissions = [[NSArray alloc] initWithObjects:
                        @"email",
                        nil];

// Attempt to open the session. If the session is not open, show the user the Facebook login UX
[FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:true completionHandler:^(FBSession *session, FBSessionState status, NSError *error)
{
    // Did something go wrong during login? I.e. did the user cancel?
    if (status == FBSessionStateClosedLoginFailed || status == FBSessionStateCreatedOpening) {

        // If so, just send them round the loop again
        [[FBSession activeSession] closeAndClearTokenInformation];
        [FBSession setActiveSession:nil];
        [self Facebook_CreateNewSession];
    }
    else
    {
    }                  
}];
}

+ (void) Facebook_PostToNewsFeedWithTitle:(NSString*)title withCaption:(NSString*)caption withDescription:(NSString*)description withLink:(NSString*)link withPictureURL:(NSString*)picURL
{

// check if user is logged in
if ([FBSession activeSession] == nil)
{
    [FacebookHandler Facebook_CreateNewSession];
    [FacebookHandler Facebook_Login];
}


// This function will invoke the Feed Dialog to post to a user's Timeline and News Feed
// It will attemnt to use the Facebook Native Share dialog
// If that's not supported we'll fall back to the web based dialog.

NSString *linkURL = link;
NSString *pictureURL = picURL;

// Prepare the native share dialog parameters
FBShareDialogParams *shareParams = [[FBShareDialogParams alloc] init];
shareParams.link = [NSURL URLWithString:linkURL];
shareParams.name = title;
shareParams.caption= caption;
shareParams.picture= [NSURL URLWithString:pictureURL];
shareParams.description = description;

if ([FBDialogs canPresentShareDialogWithParams:shareParams]){

    [FBDialogs presentShareDialogWithParams:shareParams
                                clientState:nil
                                    handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
                                        if(error) {
                                            NSLog(@"Error publishing story.");
                                        } else if (results[@"completionGesture"] && [results[@"completionGesture"] isEqualToString:@"cancel"]) {
                                            NSLog(@"User canceled story publishing.");
                                        } else {
                                            NSLog(@"Story published.");
                                        }
                                    }];

}else {

    // Prepare the web dialog parameters
    NSDictionary *params = @{
                             @"name" : shareParams.name,
                             @"caption" : shareParams.caption,
                             @"description" : shareParams.description,
                             @"picture" : pictureURL,
                             @"link" : linkURL
                             };

    // Invoke the dialog
    [FBWebDialogs presentFeedDialogModallyWithSession:nil
                                           parameters:params
                                              handler:
     ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
         if (error) {
             NSLog(@"Error publishing story.");
         } else {
             if (result == FBWebDialogResultDialogNotCompleted) {
                 NSLog(@"User canceled story publishing.");
             } else {
                 NSLog(@"Story published.");
             }
         }}];
}

    [FacebookHandler Facebook_PostToNewsFeedWithTitle:title withCaption:caption withDescription:description withLink:link withPictureURL:picURL];

更新

这似乎是Facebook应用程序的问题。在卸载了Facebook的设备上试用时，系统会要求我登录，然后它会成功发布。但是，如果安装了Facebook，它不会发布。

我通过手动在plist文件中键入“URL类型”键来修复它。

不要复制粘贴另一个plist文件中的plist值-这是苹果的bug

当它在模拟器中运行良好时，我也面临这个问题。到目前为止有解决方案吗？我也有同样的问题。
