來自UIview的快照不顯示圓弧和圓角

Question

我正在通過UIBezierPath製作uiview上的圓弧。它正在做精細的圓弧，但是當我將此UIView的快照用於共享圓弧時，不會顯示在快照中。 uiview顯示爲默認值，弧形和圓形rectcorner不顯示。這裏是快照代碼 CGSize sz = CGSizeMake（bottomview.frame.size.width，bottomview.frame.size.height）;

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

    resultImageView.image=image; 

這裏是代碼用於使電弧 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; 

我不知道它爲什麼會發生。任何人都可以幫助我。

Answer 1

我有我的地方bottomview.layer.mask = maskLayerbottom;試圖
[bottomview.layer addSublayer:maskLayerbottom];的答案，從UIView正在顯示弧快照。

Answer 2

您是否嘗試過加入這個？

[bottomview.layer setMasksToBounds:YES];
