Facebook SDK 3.1.1，iOS 6，FBNativeDialogs

Question

当我尝试在ios 6上显示共享对话框时，我的应用程序未显示FBNativeDialogs！

我正在使用DEFacebookComposeViewController库，在ios 4.3、5.0和5.1上还可以，该对话框在应用程序获取facebooktoken后出现。 但是在iOS 6上，如果该应用程序具有Facebook令牌（我是说该应用程序已经安装了令牌，例如用户使用Facebook登录），则不会出现该对话框。 仅在没有令牌然后才起作用的情况下显示。 并与iOS 6 DEFacebookComposeViewController它不起作用。 FBNativeDialogs返回，错误代码为7。所以我的问题是如何在iOS 6上调用DEFacebookComposeViewController或在已有Facebook令牌的情况下如何使用FBNativeDialogs。

 BOOL displayedNativeDialog = [FBNativeDialogs
 presentShareDialogModallyFrom:self
 initialText:@""
 image:nil
 url:[NSURL URLWithString:@"www.google.com"]
 handler:^(FBNativeDialogResult result, NSError *error) {

     // Only show the error if it is not due to the dialog
     // not being supporte, i.e. code = 7, otherwise ignore
     // because our fallback will show the share view controller.
     if (error && [error code] == 7) {
         return;
     }

     NSString *alertText = @"";
     if (error) {
         alertText = [NSString stringWithFormat:
                      @"error: domain = %@, code = %d",
                      error.domain, error.code];
     } else if (result == FBNativeDialogResultSucceeded) {
         alertText = @"Posted successfully.";
     }
     if (![alertText isEqualToString:@""]) {
         // Show the result in an alert
         [[[UIAlertView alloc] initWithTitle:@"Result"
                                     message:alertText
                                    delegate:self
                           cancelButtonTitle:@"OK!"
                           otherButtonTitles:nil]
          show];
     }
 }];

// Fallback, show the view controller that will post using me/feed
if (!displayedNativeDialog)
{
    UIDevice *device = [UIDevice currentDevice];
    CGFloat systemVersion = [[device systemVersion] floatValue];
    if (systemVersion > 5.5)
    {
        return;
    }
    DEFacebookComposeViewController *facebookViewComposer = [[DEFacebookComposeViewController alloc] init];
    self.modalPresentationStyle = UIModalPresentationCurrentContext;
    [facebookViewComposer setInitialText:@""];
    [facebookViewComposer addURL:@"www.google.com"]];

    [facebookViewComposer setCompletionHandler:^(DEFacebookComposeViewControllerResult result) {
        switch (result) {
            case DEFacebookComposeViewControllerResultCancelled:
                NSLog(@"Facebook Result: Cancelled");
                break;
            case DEFacebookComposeViewControllerResultDone:
                NSLog(@"Facebook Result: Sent");
                break;
        }

        [facebookViewComposer dismissModalViewControllerAnimated:YES];
    }];
    [self presentModalViewController:facebookViewComposer animated:YES];

    [facebookViewComposer release];
}

您需要在设备/模拟器上设置Facebook帐户（在“设置”->“ Facebook”下）。
