iOS uses Uibezierpath to implement Progressview

The implementation results are as follows:

The interface is implemented with UITableView and Tabelviewcell, and the Red view is drawn with Uibezierpath. Note The red part of the upper left corner, the lower left corner is right angle yo!!!! Not much to say < here is really willing to use Uibezierpath to achieve!!!?? The code is as follows:

Tabelviewcell Code:

is not super simple, but I did not think at first, or own too much food. ... Fight IT!!!
