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];
-(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找一找教程网。
