One way to adjust the size of a custom Shape
to fit a frame is by using the GeometryReader
view modifier to get the dimensions of the frame and then calculating the appropriate scale factor.
Here's an example:
struct MyShape: Shape {
func path(in rect: CGRect) -> Path {
// Define the path of your custom shape
...
}
}
struct MyShapeView: View {
var body: some View {
GeometryReader { geometry in
MyShape()
.scaleToFit(geometry.size)
}
}
}
extension Shape {
func scaleToFit(_ size: CGSize) -> some View {
let scaleFactor = min(size.width / self.boundingRect.width, size.height / self.boundingRect.height)
return self.scale(scaleFactor)
}
}
In this example, we define a custom MyShape
that we want to fit inside a frame. We then use the GeometryReader
to get the dimensions of the frame and pass it to a custom view modifier scaleToFit
, which calculates the appropriate scale factor using the boundingRect
property of the Shape
. Finally, we apply the calculated scale factor to the Shape
using the scale
modifier.
Note that if your custom Shape
is not centered at (0, 0), you may need to adjust its position after scaling to ensure that it is aligned correctly within the frame.
