我正在尝试将 Facebook 集成到我的应用程序中。我需要用户的生日、姓名和电子邮件。
我已经集成了Facebookloginview来自 sdk 的。
如果我点击登录，应用程序会切换到 Safari，并且页面显示我已经授权了该应用程序。但我无法收到电子邮件或生日
如果我更改了类似的权限user_location，然后注销并登录应用程序显示它已经被授权但不是！
如果我在 xib 上实现一个按钮，然后添加到 ibaction，则此代码有效。
AppDelegate *appDelegate [[UIApplication sharedApplication] delegate];
// If the person is authenticated, log out when the button is clicked.
// If the person is not authenticated, log in when the button is clicked.
if (FBSession.activeSession.isOpen) {
[appDelegate closeSession];
} else {
// The person has initiated a login, so call the openSession method
// and show the login UX if necessary.
[appDelegate openSessionWithAllowLoginUI:YES];
}
}
为什么它不适用于 facebookloginview？
这是我的 facebook loginviewcontroller.m
- (void)viewDidLoad
{
[super viewDidLoad];
loginview = [[FBLoginView alloc]init];
loginview.readPermissions = @[@"email"];
//Facebook start
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(sessionStateChanged:)
name:FBSessionStateChangedNotification
object:nil];
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate openSessionWithAllowLoginUI:NO];
if (!appDelegate.session.isOpen) {
// create a fresh session object
appDelegate.session = [[FBSession alloc] init];
// if we don't have a cached token, a call to open here would cause UX for login to
// occur; we don't want that to happen unless the user clicks the login button, and so
// we check here to make sure we have a token before calling open
if (appDelegate.session.state == FBSessionStateCreatedTokenLoaded) {
// even though we had a cached token, we need to login to make the session usable
[appDelegate.session openWithCompletionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// we recurse here, in order to update buttons and labels
[self updateView];
}];
}
}
}
-(void) loginViewShowingLoggedOutUser:(FBLoginView *)loginView{
self.loginlabel.text = @"";
self.FBimageViewOutlet.profileID = nil;
