Question

您好我已经为iOS 6应用程序集成了Facebook SDK.Facebook身份验证＆amp;分享工作完美，但没有规定关闭FB对话box.ie.当FB Dialogue框打开时，它将在认证成功后关闭。没有提供关闭或导航回来。如何创建一个关闭按钮。我正在使用的代码片段如下所示。谢谢提前。

-(NSDictionary *)shareFacebook
{

    NSDictionary *userInfo;
    if (FBSession.activeSession.isOpen)
    {

        if (FBSession.activeSession.isOpen)
        {

            [self.closeButton setHidden:NO];
            [FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id<FBGraphUser> user, NSError *error) {

                NSUserDefaults *standardUserDefaults=[NSUserDefaults standardUserDefaults];
                [standardUserDefaults setObject:user forKey:@"fbUserInfo"];



                    [self.manager authenticateUserUsingFB:[user objectForKey:@"email"]];


            }];
        }

    }
    else{
        NSLog(@"fb session not active.");
        [self openSessionWithAllowLoginUI:YES];
    }
    return userInfo;
}

- (void)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {

    NSArray *permissions = [[NSArray alloc] initWithObjects:

                            @"user_photos",
                            @"publish_actions",
                            @"read_stream",
                            @"friends_photos",
                            @"email" ,nil];

    [FBSession setActiveSession:[[FBSession alloc] initWithPermissions:permissions]];


    [[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView

                              completionHandler:^(FBSession *session,

                                                  FBSessionState state,

                                                  NSError *error) {

                                  NSLog(@" state=%d",state);
                                  if(FBSessionStateOpen)
                                  {
                                      [self shareFacebook];
                                  }
                              }];

}

通过将FacebookSDKResources.bundle文件从FacebookSDK.framework / Resources文件夹拖到Project Navigator的Frameworks部分，添加适用于iOS资源包的Facebook SDK。 http://developers.facebook.com/docs/getting-started/facebook-sdk-for-ios/

我知道导致这个错误的原因！按钮和图标视图（对话框右上角有两个视图 - 关闭按钮和图标视图）实际存在（您可以单击它以查看）但不可见。这是因为项目无法查看位于FBDialog.bundle的实际图像文件。您应该从捆绑中复制这些图像并将它们添加到项目中，然后直接设置图像。您的init方法可能如下所示：

 //This is your FBDialog.m file
- (id)init {
  if (self = [super initWithFrame:CGRectZero]) {
    .........

    UIImage* iconImage = [UIImage imageNamed:@"fbicon.png"];
    UIImage* closeImage = [UIImage imageNamed:@"close.png"];

    _iconView = [[UIImageView alloc] initWithImage:iconImage];
    [self addSubview:_iconView];

    _closeButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    [_closeButton setImage:closeImage forState:UIControlStateNormal];
    [_closeButton addTarget:self action:@selector(cancel)
      forControlEvents:UIControlEventTouchUpInside];

    .........

可能有更好的方法可以解决这个问题，但这对我有用。

iOS中的FacebookSDK不显示关闭按钮且无法关闭
