私は現在、ユーザーが画像をドラッグアンドドロップしてアップロードできるようにする Mac 用の Imgur のクライアントをコーディングしています。UploadToImgur 関数のコーディングを終えたところですが、次の場所で SIGABRT エラーが発生しています。
int main(int argc, char *argv[])
{
return NSApplicationMain(argc, (const char **)argv);
}
明確にするために、コーディングしたアップロード ボタンをクリックすると、SIGABRT エラーが発生します。これは基本的に画像を取得し、それを NSData に変換して、uploadToImgur に送信します。該当する両方の機能のコードを提供できます。
コンソールには次のように表示されます。
