当用户 session 打开时如何获取用户名。我尝试了 Facebook sdk 示例中的 session 登录示例。如果有人知道解决方案,请帮助我。 提前致谢。
- (IBAction)buttonClickHandler:(id)sender {
// get the app delegate so that we can access the session property
SLAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
// this button's job is to flip-flop the session from open to closed
if (appDelegate.session.isOpen) {
// if a user logs out explicitly, we delete any cached token information, and next
// time they run the applicaiton they will be presented with log in UX again; most
// users will simply close the app or switch away, without logging out; this will
// cause the implicit cached-token login to occur on next launch of the application
//hear i need to fetch user name ?
[appDelegate.session closeAndClearTokenInformation];
} else {
if (appDelegate.session.state != FBSessionStateCreated) {
// Create a new, logged out session.
appDelegate.session = [[FBSession alloc] init];
}
// if the session isn't open, let's open it now and present the login UX to the user
[appDelegate.session openWithCompletionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// and here we make sure to update our UX according to the new session state
[self updateView];
}];
}
}
最佳答案
登录验证后,您可以从事件的 FBSession 中获取详细信息,如下所示
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *user,
NSError *error) {
if (!error) {
NSString *firstName = user.first_name;
NSString *lastName = user.last_name;
NSString *facebookId = user.id;
NSString *email = [user objectForKey:@"email"];
NSString *imageUrl = [[NSString alloc] initWithFormat: @"http://graph.facebook.com/%@/picture?type=large", facebookId];
}
}];
}
更新:代替 id
使用 objectID
属性,在版本 v3.14.1(2014 年 5 月 12 日)发布后,id
属性已被弃用
NSString *facebookId = user.objectID;
