iPhone SDK将视图及其子视图向后移动

Question

I have an application with multiple views that contain subviews. I know that you can hide or make visible a view and its subviews by setting the hidden property to YES or NO. However with a number of views, to use the hidden property requires keeping track of what view is being displayed. I thought I could use sendSuBViewToBack: to hide a view and moveSubViewToFront to make it visible. However, these methods appear to only act on the specific subview and not its child subviews. For example, a view with a couple of labels on it, when sent to the back, the labels remain visible.

Is there any way to make this behavior work besides using the hidden property?

Thanks,

Jim

Answer 1

UIViewController seems like what you're looking for. Or rather, what you should be looking for.

I'm not quite sure what exactly you're having trouble with here. As long as you're keeping track of each "container" view (perhaps using a @property ), you should be able to show/hide them on demand using a method in your code (which can be as simple as hiding all container views, and then showing the one you desire).
