创建一个下拉列表 [英] Creating a drop down list

问题描述

我想从头开始制作一个下拉列表。任何人都可以告诉我如何做？

解决方案

你将从一个UITextField和一个按钮开始看起来像一个正常的关闭下拉列表。然后当按钮被点击时，我将添加一个包含一个小的UITableView的新视图，用于下拉部分。这不应该太难了。不过我会重新考虑一个下拉框的需要。它只是不是你有屏幕上的空间，而UIPickerView更适合IMHO。现在在iPad上，他们使用了类似于上面描述的下拉菜单，但它在屏幕上有足够的空间使其变得实用。

I want to make a drop-down list from scratch. Can anyone please tell me how to do so?

解决方案

You would start with a UITextField and a button to look like a normal closed drop down list. Then when the button is clicked I would add a new view containing a small UITableView for the drop down part. It shouldn't be too hard. However I'd reconsider the need for a drop down box. Its just not something that you have room on screen for, and the UIPickerView is better suited IMHO. Now on the iPad they use a drop down similar to what I described above but it has enough room on the screen to make this practical.
