Create a table view with UITableViewStylePlain.
After this use:

tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

Then subclass the UITableViewCell class and in the drawRect: method you can draw any shape you would like to.

Views in iOS (including table cells) are always rectangular. So what you need to do is:

• Create a custom UITableViewCell (there are lots of examples and tutorials).
• When calculating the cell size, you need to calculate the bounding box of your shape. For example, if you want to draw a circle with radius r, you return a height of r * 2.
• Set [UIColor clearColor] as background color.
• In the drawRect: method, draw your shape.
