And when i select any row in table view.then removing the view from super view.when I added the subview to root view..I want to disable root view interaction without effecting the subviews interaction. Is is possible?

Answer 1

放置一个透明或半透明的叠加视图（Alpha = 0到0.5），在根视图的顶部有frame = rootView.frame，然后将你的表视图放入这个叠加视图，没有触摸事件可以通过，呵呵。

Answer 2

The value of userInteractionEnabled affects all subviews of the view it's set to, so no, not in the way you're thinking. If you wish to disable touch events for a view, subclass it and override - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event to forward it's touches to the other view.
