1. Code examples

-(void) Viewdidload {

[Super Viewdidload];

Cashapelayer *shape = [Cashapelayer layer];

Uibezierpath *bezierpath = [Uibezierpath bezierpathwithroundedrect:cgrectmake (n, N, A, a) cornerradius:98];

Shape.path = Bezierpath.cgpath;

Shape.fillcolor = [Uicolor Clearcolor]. Cgcolor;

Shape.strokecolor = [Uicolor Bluecolor]. Cgcolor;

Shape.linewidth = 4.f;

Shape.strokestart = 0.F;

Shape.strokeend = 0.7f;

[Self.view.layer Addsublayer:shape];

Self.shape = shape;

}

-(Ibaction) BTN: (ID) Sender {

CGFloat Text = (Arc4random ()%100)/100.f;

NSLog (@ "====%f", text);

Self.shape.strokeStart = text;

}

2. The top end is the Strokestart, the lower left is the strokeEnd2.1. When Strokestart>strokeend,shapelayer cannot display 2.2. The range of strokestart,strokeend values is 0-1, including 0, 12.3. Changing Strokestart or strokeend will trigger an implicit animation of Shapelayer
