当我的代码中有我的方法formatPhoneNumber/textField方法时，它不允许我键入任何其他字段。当我删除它们时，问题就消失了。有人能告诉我导致这个问题的代码出了什么问题吗？

在shouldChangeCharactersInRange:方法中将fieldPhone更改为textField，这与UITextField fieldPhone的本地声明冲突。
您还需要将该方法中的所有引用更新为新的textField。因此，您的新方法将如下所示：- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string。
