こんにちは、みんな、
[Error: objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)]
I am running an application which will produce sound after button is clicked ,
エラーを見た後、オーディオのすべてのフレームワークを含めました
[ objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
]
スタックオーバーフローからですが、それでも私には機能しません..以下のコードを見てください私は私の.hと.mファイルを含めて、私にいくつかの解決策を提案します
リンカエラーの可能性がありますが、ビルドフェーズからフレームワークを含め、＃importフレームワークを含めました..何かが足りない場合は、以下のコードを確認してください...私はiPhone開発の独学初心者です..
