Bezierpath圆角

Question

我使用以下代码显示三角视图之类的指针，如下图所示。

 UIView *triangleView = [[UIView alloc] initWithFrame:CGRectMake(70.0f,58.0f, self->_createAccountView.frame.size.width ,20.0f)];
    UIBezierPath* trianglePath = [UIBezierPath bezierPath];
    [trianglePath moveToPoint:CGPointMake(0, 0)];
    [trianglePath addLineToPoint:CGPointMake((self->_createAccountView.frame.size.width/7) -8, (self->_createAccountView.frame.size.height/4))];
    [trianglePath addLineToPoint:CGPointMake((self->_createAccountView.frame.size.width/5) , 0)];
    [trianglePath closePath];
    trianglePath.lineJoinStyle = kCGLineJoinRound;

    CAShapeLayer *triangleMaskLayer = [CAShapeLayer layer];
    [triangleMaskLayer setPath:trianglePath.CGPath];
    triangleView.backgroundColor = [UIColor colorWithRed:1.00 green:1.00 blue:1.00 alpha:1.0];

    triangleView.layer.mask = triangleMaskLayer;
    [self->_AccountView addSubview:triangleView];

这很好但我希望三角形视图的指向边缘是圆形的。如何使它圆润？任何帮助表示赞赏！

将lineJoin更改为kCALineJoinRound。

triangleMaskLayer.lineJoin = kCALineJoinRound;
