系統沒有textFeild 的相關當輸入內容改變時候的代理方法。。。所以我們自己加一個監聽來實現如下的效果
自動跳轉下一位
主要代碼如下：
[_code1F becomeFirstResponder]; [_code1F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [_code2F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [_code3F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [_code4F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [_code5F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged]; [_code6F addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
-(void)textFieldDidChange :(UITextField *)textField{ if (textField.text.length == 1) { if (textField == _code1F) { [_code2F becomeFirstResponder]; }else if (textField == _code2F){ [_code3F becomeFirstResponder]; }else if (textField == _code3F){ [_code4F becomeFirstResponder]; }else if (textField == _code4F){ [_code5F becomeFirstResponder]; }else if (textField == _code5F){ [_code6F becomeFirstResponder]; }else{ [self.view endEditing:YES]; } }}以上這篇iOS 輸入驗證碼或密碼,自動下一位的實例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持VEVB武林網。
