copied!<p>Write a UIViewController that manages your 2 VC's and transitions between the MKMapView and UITableView in response to the segmented control. First set up the nib for this new VC in Interface Builder: add an UISegementedControl and a simple UIView (contentView). The interface file contains references to the UI Elements and to the 2 VC's + an action to respond to the segmented control:</p> <pre><code>// // MapAndTableViewController.h // #import <UIKit/UIKit.h> #import "MyMapViewController.h" #import "MyTableViewController.h" @interface MapAndTableViewController : UIViewController { IBOutlet UISegmentedControl* segmentedControl; IBOutlet UIView* contentView; UIViewController* firstVC; UIViewController* secondVC; } -(IBAction) valueChanged:(UISegmentedControl*) sender; @end </code></pre> <p>Implementation:</p> <pre><code>// // MapAndTableViewController.m // #import "MapAndTableViewController.h" @implementation MapAndTableViewController -(IBAction) valueChanged:(UISegmentedControl*) sender { if (sender.selectedSegmentIndex == 0) { [UIView transitionFromView:[contentView.subviews lastObject] toView:firstVC.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil]; } if (sender.selectedSegmentIndex == 1) { [UIView transitionFromView:[contentView.subviews lastObject] toView:secondVC.view duration:0.5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:nil]; } } -(void)awakeFromNib { firstVC = [[MyMapViewController alloc] initWithNibName:@"MyMapViewController" bundle:nil]; secondVC = [[MyTableViewController alloc] initWithNibName:@"MyTableViewController" bundle:nil]; } - (void)viewDidLoad { [super viewDidLoad]; [contentView addSubview:firstVC.view]; } - (void)dealloc { [firstVC release]; [secondVC release]; [super dealloc]; } @end </code></pre> <p>In the <code>valueChanged</code> method you replace the current view and animate the transition.</p> <p>Note that the views <code>firstVC.view</code> and <code>secondVC.view</code> are created on first access of the view-property of each VC.</p>
