如何为iPhone创建滚动拨盘
[英]How can I create a Scrolling Dial for the iPhone
问题描述
So I have all the images I need to create a Scroller Dial for the iPhone, but I don't know how I should animate them. 
因此，我拥有创建iPhone的Scroller Dial所需的所有图像，但是我不知道该如何设置它们的动画。
Basically I have a scroll dial that will essentially act as a UISlider but i'd like it to slow down as it spins. 基本上，我有一个滚动拨号盘，它实际上将充当UISlider，但我希望它在旋转时减速。
How can I do something like that or where should I look to learn about these things 我该如何做类似的事情，或者应该去哪里学习这些东西？

Use a UIScrollView. 使用UIScrollView。 That will decelerate how you want and if you need it to form to a specific "tick", scroll the contentOffset of the scrollview to the proper tick. 这将降低您的需求，如果您需要将其形成为特定的“刻度”，请将scrollview的contentOffset滚动到适当的刻度。
