I've got an app that appeals to an older demographic. The interface is simple but with some custom controls where a simple graphic is not completely self explanatory (save to playlist, sort by genre for example).
I've seen plenty of apps with great first run walkthroughs (examples here) but don't know if there are some existing libraries out there.
Your suggestions are welcome.
I found CMPopTipView that, while it doesn't fit my needs completely may be of use to those that are looking to pop a tool tip every now and then.
Most of these overlays/walkthroughs can be accomplished by adding a subview to the main window of your app. There are some edge cases to take into account, but for the most part, you need to simply grab a reference to the key window with
UIWindow* keyWindow;
keyWindow = [UIApplication sharedApplication].keyWindow;
You then would add your overlay view as a subview with:
[keyWindow addSubview:anOverlayView];
Handling taps to dismiss the overlay can be done with a tap gesture recognizer.
