我试着调用FBRequest:requestForMe:startWithCompletionHandler,无法让它在我自己的代码中工作,所以试图将它添加到示例项目SessionLoginSample中,但仍然得到结果相同的结果是零。调用FBRequest:requestForMe:返回零结果
我已经添加到示例项目内的UpdateView方法,但它并没有区别的地方放置,ID始终为零:
- (void)updateView {
// get the app delegate, so that we can reference the session property
SLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
if (appDelegate.session.isOpen) {
// valid account UI is shown whenever the session is open
[self.buttonLoginLogout setTitle:@"Log out" forState:UIControlStateNormal];
[self.textNoteOrLink setText:[NSString stringWithFormat:@"https://graph.facebook.com/me/friends?access_token=%@",
appDelegate.session.accessTokenData.accessToken]];
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSDictionary<FBGraphUser> *my = (NSDictionary<FBGraphUser> *) result;
NSLog(@"My dictionary: %@", my.first_name);
}];
} else {
// login-needed account UI is shown whenever the session is closed
[self.buttonLoginLogout setTitle:@"Log in" forState:UIControlStateNormal];
[self.textNoteOrLink setText:@"Login to create a link to fetch account data"];
}
}
的NSError包含域:com.facebook.sdk代码: 5.
经过一些谷歌搜索和实验后,我通过在它之前添加一个对[FBSession setActiveSession:appDelegate.session]的调用来运行requestForMe,但是我无法将这个工作代码转移到我自己的项目中,相同的错误代码为5,但是我看不出我的项目代码与示例项目的区别。
