Troubles using CGPathContainsPoint SWIFT

问题:

I need to check if a CGPoint is inside a SKSpriteNode.

After a little research, CGPathContainsPoint seems appropriated for my purpose.

if CGPathContainsPoint(my_sprite_path, nil, my_point, false) {

 }

But Xcode alerts me: Use of unresolved identifier CGPathContainsPoint

I tried to import :

import UIKit
import CoreGraphics

I'm using Xcode 8.0 beta 6.

Did I miss anything?

回答1:

As of Swift 3, many Core Graphics functions are now methods on the corresponding type. In your example:

if my_sprite_path.contains(my_point) {

}
