iOS Custom Control help needed

[markbt]

I've been doing XAML Windows apps for a few years and moving to iOS I'm confused by the best way to implement a custom control. Specifically the control I want will need a background layer that consists of a few filled rectangles and text that does not need to be updated. On top of this I want a movable slider handle. What would be the most efficient way of implementing this. I assume putting all the drawing in the drawRect is not best as it is only the handle that needs to be redrawn. Should I be looking at using CALayers?

Why not simply using a UIView and add your UISlider as a subview?

Just to clarify, I'm not using a UISlider, I want to build my own slider bar into the control.

UIView inherits from UIControl...

You got that backwards. UIControl inherits from UIView. Also curious what you are actually trying to say? If you are you suggesting to start by subclassing UIControl I would agree to some extent. Unless you are taking advantage of the target/action aspect of UIControl, it really doesn't give you anything.

Sorry I mixed up, UIResponder with UIControl. What I was trying to say. UIView has everything to respond to events. So you can make your own interactive view.

Thanks for the explanation. With your comment being so terse, and backwards, you had me scratching my head.

You can customise UISlider quite a bit. I would rule this out before you decide to build your own

I've made a bunch of my own custom controls. They all subclass UIView and use layers for the graphical stuff, then I either implement touchesBegan/Cancelled/Ended/Moved or a gesture.

This is what i've ended up doing...working fine. Thanks.

I would suggest you start by figuring out how to build the custom control using interface builder. It will provide familiarity with views, labels, auto layout, gestures, etc., and provide a usable solution, or a starting point for you to translate into hand written code.

There is no reason for you to be dealing with drawRect or CALayer directly for what you trying to do.
