1.在注册界面点击事件把数据存进去

NSUserDefaults *user = [NSUserDefaults standardUserDefaults];

NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:_ac1.text,@"name",_pw1.text,@"password", nil];
[user setObject:dic forKey:@"user"];

[self.navigationController popViewControllerAnimated:YES];

2.在登录界面点击事件里把数据取出来

NSUserDefaults *user = [NSUserDefaults standardUserDefaults];
NSDictionary *dic = [user objectForKey:@"user"];
if ([_oneV.aa.text isEqualToString:[dic objectForKey:@"name"]] && [_oneV.bb.text isEqualToString:[dic objectForKey:@"passwaord"]]) {

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@" 登录成功" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
        [alert show];
    }else{

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"登录失败" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定 ", nil];

        [alert show];

    }
