A demonstration of moving an object along a bezier path in iOS
The PathMove program allows the user to set up a predetermined set of bezier paths and then trigger a UIImageView object to move from start to end along that path.
PathMove is available both in the iTunes store and as source code from GitHub, and you can find out more about it on my blog.
The program incorporates several options to do things like:
The program consists of two screens – a main screen where the path is drawn and the object moves, and a setup screen which contains all the options that the user can make. The following screen shots show the object moving along a path and the corresponding setup screen that created the path. The final screen shot shows how the bezier path can be annotated in order to show all the control points.
