ios实现带有输入框的AlertView

1,实现一个alertView

    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"" message:@"请输入Wi-Fi密码" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
    alertView.alertViewStyle = UIAlertViewStyleSecureTextInput;
    [alertView show];

2，实现代理方法

#pragma mark - UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    UITextField *passwordText = [alertView textFieldAtIndex:0];
//    passwordText.
    NSLog(@"%@",passwordText.text);
    NSLog(@"buttonIndex:%d",buttonIndex);
}
