这里写图片描述

UIButton* btn = [UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(0, 20, 60, 40);
    btn.backgroundColor = [UIColor grayColor];
    [btn setTitle:@"按钮" forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];

    UIAlertView* alertView = [[UIAlertView alloc]initWithTitle:@"温馨提示" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
    alertView.tag = 1;
    //设置提示框的类型
    alertView.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
    [self.view addSubview:alertView];

调用的方法：

-(void)btnAction:(UIButton*)sender
{
    UIAlertView* alertView = [self.view viewWithTag:1];
    [alertView show];
}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    //通过索引值找到账号文本输入框
    if (buttonIndex == 1) {
        UITextField* textField = [alertView textFieldAtIndex:0];
        //通过索引值找到密码文本输入框
        UITextField* textField1 = [alertView textFieldAtIndex:1];

        NSLog(@"账号:%@ 密码:%@",textField.text,textField1.text);
    }
