如何用CAShaperLayer设置角半径值？

Question

我画了一条UIBeizerPath的垂直线，我需要这条线有一个值为5的拐角半径。我试着记得[pathLayer setCornerRadius: 5];，但我没有得到结果...你能帮助我吗？我如何分配角半径值？这是我的代码使用

// crea le barre del grafico e gli assegna l'altezza della label y corrispondente 
    UIBezierPath *path = [UIBezierPath bezierPath]; 
    [path moveToPoint:CGPointMake(xPaddingFromYAxis +spaceBetweenBar *j, 200)]; 
    [path addLineToPoint:CGPointMake(xPaddingFromYAxis +spaceBetweenBar *j, yLabelValue.center.y)]; 

    CAShapeLayer *pathLayer = [CAShapeLayer layer]; 
    pathLayer.frame = self.bounds; 
    pathLayer.path = path.CGPath; 
    pathLayer.strokeColor = [UIColor darkGrayColor].CGColor; 
    pathLayer.fillColor = nil; 
    pathLayer.lineWidth = 50; 
    [pathLayer setCornerRadius:5]; 
    pathLayer.masksToBounds = NO; 
    [scroll.layer addSublayer:pathLayer];

你需要屏蔽设置绑定为“YES”。 pathLayer.masksToBounds = YES;

试试这个，看看：

UIBezierPath *path = [UIBezierPath bezierPath]; 
[path moveToPoint:CGPointMake(xPaddingFromYAxis +spaceBetweenBar *j, 200)]; 
[path addLineToPoint:CGPointMake(xPaddingFromYAxis +spaceBetweenBar *j, yLabelValue.center.y)]; 

CAShapeLayer *pathLayer = [CAShapeLayer layer]; 
pathLayer.frame = self.bounds; 
pathLayer.path = path.CGPath; 
pathLayer.strokeColor = [UIColor darkGrayColor].CGColor; 
pathLayer.fillColor = nil; 
pathLayer.lineWidth = 50; 
[pathLayer setCornerRadius:5]; 
pathLayer.masksToBounds = YES; 
[scroll.layer addSublayer:pathLayer];
