系统没有textfeild 的相关当输入内容改变时候的代理方法。。。所以我们自己加一个监听来实现如下的效果
自动跳转下一位
主要代码如下：

[_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]; |

以上这篇ios 输入验证码或密码,自动下一位的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
