このコードを見て、私がそれを修正するのを手伝ってくれるかどうか見てください：

}

問題は次のとおりです。

didSelectAnnotationViewに提供されているカスタム画像をタップすると、デリゲートメソッドが呼び出されませんMKAnnotationView。

どんな種類の助けもいただければ幸いです。

ありがとう

[annotationView setCanShowCallout:NO]

ピンをクリックしたときにコールアウトが必要ではなかったので、これで問題は解決しましたが、didSelectAnnotationViewデリゲートを呼び出して呼び出したかったのです。

ありがとう

Are you giving your annotations a title property? Are you sure that [annotationView setCanShowCallout:YES] is set properly?
