I am working on CAShapeLayer
.And trying to draw non-linear path.I want to set frame to CAShapeLayer
.So i can use CGPathGetPathBoundingBox
method to get frame from CGPathRef
.
Here is code :
CGMutablePathRef path = CGPathCreateMutable();
CGPathAddArc(path, NULL, rect.size.width/2, rect.size.height/2, 100, (0), (M_PI_2), NO);
CGPathAddArc(path, NULL, rect.size.width/2, rect.size.height/2, 100-50, (M_PI_2), (0), YES);
CGPathCloseSubpath(path);
CAShapeLayer* arcLayer = [[CAShapeLayer alloc]init];
arcLayer.path = path;
arcLayer.frame = CGPathGetPathBoundingBox(path);
arcLayer.bounds = CGPathGetPathBoundingBox(path);
[self.layer addSublayer:arcLayer]; `
Please refer my code carefully .I have set same frame and bounds to CAShapeLayer.My problem is if i am not setting bounds (same as frame) ,then it wont show my content or it wont show my content within frame.Why?Please help me.Thanking you.
