プロジェクトにSBJsonクラスとともにFBSdkを追加しましたが、コードを機能させるために2番目のViewControllerにどのファイルをインポートする必要がありますか？
urlの下の説明を使用してFbに投稿したいので、このコードを2番目のView Controllerに含める必要がありますが、次のコードを2番目のViewControllerに追加する必要があることに気づきました。デリゲート：セルフ」は機能しません。これは初めて行うので、アプリデリゲートからの値を考慮して2番目のビューコントローラーでコーディングする方法を教えてくれます（アプリデリゲートから値を取得するにはどうすればよいですか？ 2番目のビューにFBを追加して、このコードを2番目のコードに追加できるようにします。plzは誰でもこのコードを修正できます）
facebook = [[Facebook alloc] initWithAppId:@"YOUR_APP_ID"];
//アプリデリゲートからこのIDを取得するにはどうすればよいですか？
NSArray* permissions = [NSArray arrayWithObjects:@"read_stream",
@"publish_stream", nil];
[facebook authorize:permissions delegate:self];
NSMutableDictionary* params = [[NSMutableDictionary alloc]
initWithCapacity:1]
[params setObject:@"Testing" forKey:@"name"];
[params setObject:@"IMAGE_URL" forKey:@"picture"];
[params setObject:@"Description" forKey:@"description"];
[facebook requestWithGraphPath:@"me/feed"
andParams:params
andHttpMethod:@"POST"
andDelegate:self];
上記のコードは正しいですか？-（void）fb_share（メソッド）の2番目のビューコントローラーにどのように実装する必要がありますか。
私のアプリ委任ファイルは次のようになります：

デリゲートから値を取得することで、2番目のView Controllerの-（void）fb_shareメソッドにどのコードを書き込む必要があるかを誰かが理解できますか？ヘルプ！
私はこれを行いました...そしてエラーを取得します：HTTPステータスコード：400 ...しかし、ユーザー名はアラートに表示されます
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
// NSArray* permissions = [NSArray arrayWithObjects:@"read_stream",
// @"publish_stream", nil];
// [facebook authorize:permissions delegate:self];
self.params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
@"https://developers.facebook.com/ios", @"link",
@"https://developers.facebook.com/attachment/iossdk_logo.png", @"picture",
@"Facebook SDK for iOS", @"name",
@"Build great social apps and get more installs.", @"caption",
@"The Facebook SDK for iOS makes it easier and faster to develop Facebook integrated iOS apps.", @"description",
nil];
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Upload to FB?"
message:[NSString stringWithFormat:@"Upload to ""%@"" Account?", user.name]
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"No",@"Yes", nil];
[FBRequestConnection startWithGraphPath:@"me/feed"
parameters:self.params
HTTPMethod:@"POST"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Success"
message:@"PostUploaded"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
[tmp release];
}
}];
[tmp show];
[tmp release];
}
}];
.. 私は今どうすればいい ？
