iphone - FBLoginView iPhone View

Question

在当前 3.1 Facebook SDK 中使用 FBLoginView 不会产生我认为它应该产生的输出。生成一个基本的 [[FBLoginView alloc] init]；和框架当前 View Controller 框架的大小，它只显示下面没有“登录”按钮:

如何使 FBLoginView 正常显示？

Answer 1

试试这个:

在 .h 文件中:

Use this delegate <FBLoginViewDelegate>

FBLoginView *loginview;

在someMethod中的.m文件中:

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];

添加这些方法:

- (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");
}

希望这对您有所帮助。
