I would like to know how to create a custom iPhone control from scratch, or using an existing library or framework.
I have seen the three20 library, aswell as tapku and touch customs which are nice for specialised iOS controls such as table view etc but I'm talking about making totally custom, interactive controls here.
Lets say I wanted to make a dial control similar to the one from this app: http://store.apple.com/us/product/H2654LL/A.
Where would I start?
- Would I subclass UIView and customize it?
- Would I use quartz 2d?
- Would I use OpenGL ES to draw something like this to the screen?
- Can I still use IB to design/layout my custom view?
I'm just a bit confused which way to go here.
Yes - this question has been asked and answered a few times before, but I am yet to find a satisfactory answer which addresses the above points.
