ios - 在 IOS 中触摸 View 时可以在触摸点上发光吗？

Question

就像标题一样，当我触摸 UIView 时我希望触摸点发光，我想到了在触摸点上显示发光图像的想法，但是如果通过代码？有什么例子或想法吗？谢谢分享!!

Answer 1

您可以在代码下面尝试 touchesBegan 事件:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
   if([touch view] ==self.my_view)//Check click your uiview or not
  {
       CGRect frame = [your_image_view frame];
       CGPoint touchLocation = [touch locationInView:touch.view];
       frame.origin.x=touchLocation.x;
       frame.origin.y=touchLocation.y;
       [your_image_view setFrame:frame];
       [self.my_view addSubview:your_image_view];
  }

}

谢谢...!
