Question

NSString *facebookIDString = [NSString stringWithFormat:@"%lld", facebookID];
// Put together the dialog parameters
NSMutableDictionary *params =
[NSMutableDictionary dictionaryWithObjectsAndKeys:
 facebookIDString, @"to",
 @"MY APP NAME", @"name",
 @"MY APP CAPTION", @"caption",
 @"MY APP DESCRIPTION", @"description",
 @"http://www.myApp.com", @"link",
 @"https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png", @"picture",
 FACEBOOK_APP_ID, @"app_id",
 nil];

// Invoke the dialog
[FBWebDialogs presentDialogModallyWithSession:[FBSession activeSession]
                                           dialog:@"feed"
                                       parameters:params
                                          handler:
 ^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
    //My code here
 }];

更新：我刚刚在params中注释了@“picture”键，现在我看到“Post to Wall”标题带有“Okay”按钮，但模态的内容显示“无法发布到用户的墙上”（实际上这是是随机的，有时会发生......大部分时间我仍然是空视图）

如果我删除@“to”键，模式似乎按预期工作，内容发布到我自己的墙上，但我想发布到朋友的墙上。

我认为这是权限问题，但我打印出[FBSession activeSession]并且我有publish_stream

<FBSession: 0x146a72d0, state: FBSessionStateOpen, loginHandler: 0x146a77d0, appID: <My APP_ID>, urlSchemeSuffix: , tokenCachingStrategy:<FBSessionTokenCachingStrategy: 0x145c3b20>, expirationDate: 4001-01-01 00:00:00 +0000, refreshDate: 2014-02-22 18:14:14 +0000, attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(

我发现了我的问题。我假设FBGraphUser。id的类型为long long，而不是NSString*，所以我正在投射它并进行转换，这会产生无效的ID我猜...现在它显示正确。

猜猜我应该检查一下这个文档： https://developers.facebook.com/docs/reference/ios/3.0/protocol/FBGraphUser/
