我正在尝试使用 FLoginView 为 facebook 创建登录按钮。以下是我编写的代码。
- (void)viewDidLoad
{
[super viewDidLoad];
if(!loginview)
loginview = [[FBLoginView alloc] initWithPermissions:[NSArray arrayWithObject:@"publish_actions, user_photos,status_update"]]; // Whatever permissions you need
loginview.frame = self.view.bounds; //whatever you want
loginview.delegate = self;
[self.view addSubview:loginview];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)loginViewShowingLoggedInUser:(FBLoginView *)loginView {
NSLog(@"Logged In");
}
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user {
NSLog(@"user Id %@",user.id);
}
- (void)loginViewShowingLoggedOutUser:(FBLoginView *)loginView {
// Called after logout
NSLog(@"Logged out");
}
但它没有显示登录按钮。我的代码有什么问题。在控制台中我得到“注销”。
