Use Layer.cornerradius to implement a circular view, set Layer.cornerradius to half the width of a square view, and it can be displayed as a circle. After testing, you also need to set Layer.maskstobounds to Yes, no, just test it. Set Layer.shouldrasterize to Yes is OK. Reference here.

Self. Health_percent.layer.masksToBounds = YES;
Self. Health_percent.layer.cornerRadius = self. Health_percent.frame.size.width * 0.5f;
