iOS sets the control fillet with selectable fillet direction

Preface

This article mainly introduces how to use iOS to set the control fillet that can choose the direction of fillet. Needless to say, the following is the example code of realization. Let's have a look.

Sample code

1. Set fillet by setting cornerRadius of control layer

self.view.layer.cornerRadius =10.f;// If the fillet angle is set to a semicircle, the value is the height of the control 1 Half 

self.view.layer.masksToBounds = YES;// Delete redundant locations 

2. Set fillet by Bezier curve

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:btn.bounds byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(10, 10)];

//rect Object for the control frame corners Is the position of the rounded corner  cornerRadii Is the size of the fillet 

CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];

maskLayer.frame =frame;

maskLayer.path = maskPath.CGPath;

btn.layer.mask = maskLayer;
