系統(tǒng)沒有textFeild 的相關(guān)當(dāng)輸入內(nèi)容改變時(shí)候的代理方法。。。所以我們自己加一個(gè)監(jiān)聽來實(shí)現(xiàn)如下的效果
自動(dòng)跳轉(zhuǎn)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(yàn)證碼或密碼,自動(dòng)下一位的實(shí)例就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持武林網(wǎng)。
