swift - SCNView 到 UIView？

Question

是否可以从 SCNView 转换为 UIView？我的 SCNView 上有一个覆盖层的登录按钮，但我希​​望登录按钮将用户带到 UIView 进行登录。

可能不是最优雅的方式，但这样的方法可能适合你......

- (void) handleTap:(UITapGestureRecognizer*)gestureRecognizer {

    // get tap location
    CGPoint p = [gestureRecognizer locationInView:scnView];

    // convert to sk scene coordinates
    CGPoint p2D = [scnView.overlaySKScene convertPointFromView:p];
    //test if we hit the login button
    SKNode *loginButton = [scnView.overlaySKScene nodeAtPoint:p2D];

    // assuming your loginButton is of type SKLabelNode
    if (loginButton != nil && ( [loginButton isMemberOfClass:[SKLabelNode class]]  )) // add other tests here
    { 
        // Here you can add code to transition to another 
        // view controller to handle logins


    } else {
        // do hit test on scnView here for the 3D scene
        // .........
    }

}
