我需要 ios 应用程序的 facebook 共享组件。我使用 fbcoonect 但它不能正常工作。在登录屏幕之后，当我使用 fbdialog 时它会出现白屏。sharekit 示例也给出了相同的错误。照片共享有效，但文本、链接共享在 sharekit 默认示例中不起作用。当您想分享某些内容时，它会在登录对话框后显示白色的空白屏幕。任何想法？

试试这个代码，它会工作。不要忘记在 .plist 和代码中添加您的 APP_ID。

-(void)buttonPressed:(id)sender{
facebook = [[Facebook alloc] initWithAppId:@"YOUR_APP_ID" andDelegate:self];

 NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {
            facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
            facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
        }
if (![facebook isSessionValid]) {
    [facebook authorize:nil];
}else{
[self postWall];
}
// Pre 4.2 support
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
    return [facebook handleOpenURL:url]; 
}
- (void)fbDidLogin {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [self postWall];
}
-(void)postWall{

    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"https://developers.facebook.com/docs/reference/dialogs/",@"link",
                                   @"http://fbrell.com/f8.jpg",@"picture",
                                   @"Facebook Dialogs",@"name",
                                   @"Reference Documentation",@"caption",
                                   @"Using Dialogs to interact with users.",@"description",
                                   @"Facebook Dialogs are so easy!",@"message",
                                   nil];

    [[self facebook] dialog:@"feed" andParams:params andDelegate:self];

}
