我想在我的视图中将UIBezierPath设置为掩码:
目标是这样的:
目标是这样的:
所以我用框架绘制视图:
CGFloat round = 80; UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(self.frame.size.width/2-105,210,60+round)]; myView.backgroundColor = [UIColor redColor];
然后尝试添加BezierMask:
UIBezierPath *aPath = [UIBezierPath bezierPath]; CGSize viewSize = CGSizeMake(myView.frame.size.width,myView.frame.size.height); //(210,80) CGPoint startPoint = CGPointMake(myView.frame.origin.x,myView.frame.origin.y); //(279,0) [aPath movetoPoint:startPoint]; //(279,0) [aPath addLinetoPoint:CGPointMake(startPoint.x+viewSize.width,startPoint.y)]; //(489,0) [aPath addLinetoPoint:CGPointMake(startPoint.x+viewSize.width,startPoint.y+viewSize.height-round)]; //(489,60) [aPath addQuadCurvetoPoint:CGPointMake(startPoint.x,startPoint.y+viewSize.height-round) controlPoint:CGPointMake(startPoint.x+(viewSize.width/2),80)]; //(279,60) : (384,80) [aPath closePath]; CAShapeLayer *layer = [CAShapeLayer layer]; layer.frame = myView.bounds; layer.path = aPath.CGPath; myView.layer.mask = layer; [self addSubview:myView];
但在那之后我的观点正在逐渐消失.为什么?
