我正在申请读者,可以向Facebook发送文字。 但我在另一页完成了对Facebook的标识。 我有一个叫做textpostingbt和一份载有案文的案文概览。 我需要做的是,当用户利用 but子把案文张贴到Facebook时,却不展示 log。 我在纽伦有了一些验证,因此,只有用户在。
EDIT:
- (IBAction)postGradesTapped:(id)sender {
//_posting = YES;
// If we re not logged in, log in first...
if (![_session isConnected]) {
self.loginDialog = nil;
_loginDialog = [[FBLoginDialog alloc] init];
[_loginDialog show];
_logoutButton.hidden = YES;
}
// If we have a session and a name, post to the wall!
//else if (_facebookName != nil) {
//[self postToWall];
//}
// Otherwise, we don t have a name yet, just wait for that to come through.
}
