Hello,
when tapping one of the items in the tab-bar of my iPhone app, I'd
like to switch to a view that no longer has a tab-bar. I've
accomplished this already by having the tab-bar delegate remove the
tab-bar controller view from its superview (the window) and then
instal the new view. I even got it so that the two views flip like in
an utility app. Here's the code that does it:
[UIView beginAnimations: kAnimationIDSwitchIntoGameView context: NULL];
[UIView setAnimationDelegate: self];
[UIView setAnimationDidStopSelector:
@selector(viewSwitchAnimDidStop:finished:context:)];
[UIView setAnimationDuration: kViewSwitchAnimDuration];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:
UIViewAnimationTransitionFlipFromRight
forView: window cache: YES];
[tabBarController.view removeFromSuperview];
[window addSubview: gameViewController.view];
[UIView commitAnimations];
There are two things I'm not happy about though:
1. I'd like the transition to occur in two steps, where the tab-bar
first slides down until it's gone, followed by the view flip. Is it
possible to animate the tab-bar view's frame out of the window? As a
UIView, I'd think so but then the docs say that we shouldn't access
the tab-bar view directly. I suppose I could just give it a try, but I
thought I'd ask people's input first, just in case there may be some
gotchas to look out for.
2. Once the flip happens, the new view is oddly sized, with a gap at
the bottom whose size matches the status bar. I realize that the tab-
bar resizes its current controller's view as needed, and I've tried
several combinations of the options in IB (setting the tab-bar's
controller for that one item to auto-resize or not to auto-resize its
view and changing the autoresizing behaviors of the view in question
are the two most promising ones), but I still can't get the new view
to appear correctly sized. I must admit that I don't really understand
the precise rules followed by the tab-bar controller in regards to
resizing its current view controller's view. Also, I suspect there's
some code I have to write to compensate for killing the tab-bar, but
it's not clear to me what it should be.
You can see what I'm referring to here:
