Question

I’m currently designing an app that pulls map data from a service and renders them as pins on the MKMapView. In addition, my application has been designed using storyboards where each scene is embedded within a navigation controller. The feature I’m working on requires me to give the user the ability to toggle between a map view and table view for a given result set. To provide this functionality I’ve included a bar button item in the toolBar which (when pressed) should flip the current view out and a second view in.

So far I’ve been trying to the following code but to no avail:

MapListViewController *map = [[MapListViewController alloc]init];
[UIView beginAnimations:@"flip animation" context:nil];
[UIView setAnimationDuration:3.0];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:map.view cache:YES];

[self.mapView removeFromSuperview];
[self.view addSubview:map.view];
[UIView commitAnimations];

I originally got this approach from here but it doesn’t seem to be working for me.

A couple more things to note:

• The flip view transition should only change the view currently displayed within the top and bottom navigation bars.

• Presenting the new view modally isn’t an option because I will lose site of my navigation controller.

• The view/view controller responsible for displaying the result set in a list format (i.e. UITableView) is contained within a single xib file where as the rest of the application sits within a storyboard.

Question

What is wrong with my current implementation? How should it be modified?

I haven’t used your method but I did implement flipping some views using a UIView class method. It was very easy and straightforward. Refer to the docs for other options.

[UIView transitionFromView:self.firstVC.view toView:self.secondVC.view duration:1.0 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
    // add any completion code here if needed.
}];
