我已经阅读了很多有关从Facebook获取信息的教程,但迄今为止都没有成功。我只想从Facebook获取用户名和个人资料照片。
- (IBAction)login:(id)sender {
[FBSession openActiveSessionWithReadPermissions:@[@"email",@"user_location",@"user_birthday",@"user_hometown"]
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
switch (state) {
case FBSessionStateOpen:
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (error) {
NSLog(@"error:%@",error);
} else {
// retrive user's details at here as shown below
NSLog(@"FB user first name:%@",user.first_name);
NSLog(@"FB user last name:%@",user.last_name);
NSLog(@"FB user birthday:%@",user.birthday);
NSLog(@"FB user location:%@",user.location);
NSLog(@"FB user username:%@",user.username);
NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]);
NSLog(@"email id:%@",[user objectForKey:@"email"]);
NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n",
user.location[@"name"]]);
}
}];
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
} ];
}
我使用了这段代码来获取信息,但是我无法获得任何信息。 你能帮助我吗?或者你可以推荐一些教程来帮助我吗?我已经阅读了developer.facebook.com上的教程。
非常感谢您的关注。
