iPhone: draw the objects along the curve

Question

Good day, friends.

There is a task: to draw repeating objects (UIImageView and UILabel) along the curve (if more exactly, it's an arc).

What classes should be used for it?

Answer 1

As an alternative to Android's Path, you can use either UIBezierPath or CGPath. The former is Objective-C, the later pure C. I recommend going with UIBezierPath as it's easier to use.

To rotate a view, use the transform property of UIView (see this question for an example on how to use it). But note that you then need to ignore the frame (it's undefined) and need to move the view by modifying the center instead.
