Question

我正在通过UIBezierPath在uiview上制作弧线。它正在制作精细的弧形但是当我拍摄这个UIView的快照以进行共享时，弧线不会显示在快照中。 uiview显示为默认值，并且弧形和圆形rectcorners未显示。这是快照的代码 CGSize sz = CGSizeMake（bottomview.frame.size.width，bottomview.frame.size.height）;

    UIGraphicsBeginImageContext(sz);
    [bottomview.layer renderInContext:UIGraphicsGetCurrentContext()];
    image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    resultImageView.image=image;

这里是制作弧的代码 UIBezierPath * aPathbottom = [UIBezierPath bezierPath];

[aPathbottom moveToPoint:CGPointMake(0, 262)];





[aPathbottom addLineToPoint:CGPointMake(0, 15)];
[aPathbottom addLineToPoint:CGPointMake(10, 10)];
[aPathbottom addLineToPoint:CGPointMake(20, 6)];
[aPathbottom addLineToPoint:CGPointMake(40, 3.5)];
[aPathbottom addLineToPoint:CGPointMake(60, 6)];
[aPathbottom addLineToPoint:CGPointMake(70, 10)];
[aPathbottom addLineToPoint:CGPointMake(80,15)];

[aPathbottom addLineToPoint:CGPointMake(80, 250)];
[aPathbottom addLineToPoint:CGPointMake(70, 256)];
[aPathbottom addLineToPoint:CGPointMake(60, 260.5)];
[aPathbottom addLineToPoint:CGPointMake(50, 264)];
[aPathbottom addLineToPoint:CGPointMake(55, 264.5)];
[aPathbottom addLineToPoint:CGPointMake(40, 265)];
[aPathbottom addLineToPoint:CGPointMake(45, 264.5)];
[aPathbottom addLineToPoint:CGPointMake(40, 264)];
[aPathbottom addLineToPoint:CGPointMake(20, 260.5)];
[aPathbottom addLineToPoint:CGPointMake(10, 256)];
[aPathbottom addLineToPoint:CGPointMake(0, 250)];
[aPathbottom closePath];


CAShapeLayer *maskLayerbottom = [CAShapeLayer layer];
maskLayerbottom.frame = bottomview.bounds;
maskLayerbottom.path = aPathbottom.CGPath;


bottomview.layer.mask = maskLayerbottom;

我不知道为什么会这样。可以帮助我。

问候 chakshu arora

Answer 1

我得到了我试过的答案 [bottomview.layer addSublayer:maskLayerbottom];位于bottomview.layer.mask = maskLayerbottom;，UIView的快照显示弧线。

Answer 2

您是否尝试过添加此内容？

[bottomview.layer setMasksToBounds:YES];

来自UIview的快照不显示弧和圆角
