我正在使用一些 CGRects 和 Ellipses 制作一个复杂的形状。一旦它被创建,我想抚摸这条路径。当我抚摸路径时,它会抚摸每个形状。有没有办法可以将每个形状合并成一条路径,所以笔画不相交?
int thirds = self.height / 3;
CGPathRef aPath = CGPathCreateMutable();
CGRect rectangle = CGRectMake((58 - 10) / 2, 46, 10, self.height - 58);
CGPathAddRect(aPath, nil, rectangle);
CGPathAddEllipseInRect(aPath, nil, CGRectMake((58 - 48) / 2, 0, 48, 48));
CGPathAddEllipseInRect(aPath, nil, CGRectMake((58 - 48) / 2, thirds, 48, 48));
CGPathAddEllipseInRect(aPath, nil, CGRectMake((58 - 48) / 2, thirds * 2, 48, 48));
CGPathAddEllipseInRect(aPath, nil, CGRectMake(0, self.height - 58, 58, 58));
CGPathCloseSubpath(aPath);
CGPathRef other = CGPathCreateCopy(aPath);
CAShapeLayer *square = [CAShapeLayer layer];
square.fillColor = [UIColor colorWithRed:36/255.0f green:56/255.0f blue:82/255.0f alpha:1.0f].CGColor;
square.strokeColor = [UIColor colorWithRed:50/255.0f green:70/255.0f blue:96/255.0f alpha:1.0f].CGColor;
square.path = other;
[self.layer addSublayer:square];
更新
我尝试将路径添加在一起,得到了完全相同的结果
CGPathAddPath(aPath, nil, CGPathCreateWithRect(rectangle, nil));
CGPathAddPath(aPath, nil, CGPathCreateWithEllipseInRect(CGRectMake((58 - 48) / 2, 0, 48, 48), nil));
CGPathAddPath(aPath, nil, CGPathCreateWithEllipseInRect(CGRectMake((58 - 48) / 2, thirds, 48, 48), nil));
CGPathAddPath(aPath, nil, CGPathCreateWithEllipseInRect(CGRectMake((58 - 48) / 2, thirds * 2, 48, 48), nil));
CGPathAddPath(aPath, nil, CGPathCreateWithEllipseInRect(CGRectMake(0, self.height - 58, 58, 58), nil));
