如何创建下拉框？ [英] How to create dropdown box?

问题描述

在我的应用程序中，我想在下拉框中提供选项，我知道iPhone中没有这样的事情可以使用可用的控制器创建下拉框？请任何人建议我如何实现这一点？

解决方案

Deepak，你可以创建一个下拉式的控件，帮助下UIButton和UITableView指示下拉列表。但是，确定您的应用程序将被Apple拒绝。

大多数iPhone用户都可以在iPhone应用程序中使用下拉框，因为人们习惯了Pickers

所以更好的去使用UIPicker，这是为了你所要求的。

In my app I want to provide option in dropdown box, I know there is no such thing in iPhone can I create dropdown box using available controllers? Please can anyone suggest me how I can achieve this?

解决方案

Deepak, You can create a Drop down like control with a help of a UIButton and a UITableView indicating the drop down list. But for sure your application would be rejected by Apple.

Most of the iPhone users would be comfortable using a drop down box in an iPhone app, because people got used to Pickers .

So better go for using UIPicker, which is meant for what you are asking.
