将UIImageViews坐标边界用于另一个UIImageView

通过尝试设置“Selected Box”图形的界限来显示用户在UIImageView中的触摸位置的组合。它仍然继续坚持系统的超级意见协调将UIImageViews坐标边界用于另一个UIImageView

class ViewController: UIViewController { 
@IBOutlet weak var selectedBox: UIImageView! 
@IBOutlet weak var sodukoGrid: UIImageView! 


override func viewDidLoad() { 
    super.viewDidLoad() 
    selectedBox.hidden = true 

    selectedBox.frame.origin.x = sodukoGrid.bounds.minX 
    selectedBox.frame.origin.y = sodukoGrid.bounds.minY 


    let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: Selector("tapAction:")) 

    self.sodukoGrid.userInteractionEnabled = true 
    self.sodukoGrid.addGestureRecognizer(tapGestureRecognizer) 

} 

func tapAction(sender: UITapGestureRecognizer) { 

    let touchPoint = sender.locationInView(self.sodukoGrid) 

    print(touchPoint) 

    selectedBox.center.x = CGFloat(touchPoint.x) 
    selectedBox.center.y = CGFloat(touchPoint.y) 
}
