Regexの電話番号メソッドがテキストフィールドを壊す

Question

私のコードで私のメソッドのformatPhoneNumber/textFieldメソッドを持っていると、他のフィールドに入力することができません。私がそれらを削除すると、問題はなくなります。誰かがこの問題の原因となっている私のコードに間違っていることを教えてもらえますか？

Answer 1

あなたshouldChangeCharactersInRange:方法でtextFieldに変更fieldPhone、それはUITextFieldのfieldPhoneの最寄りの宣言と矛盾です。

また、そのメソッド内のすべての参照を新しいtextFieldに更新する必要があります。したがって、新しい方法は次のようになります： - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string。
