Change View iOS

I am trying to switch through views in xcode 4.5. I am not using storyboards but am using atomatic referencing. It is an iPhone app as well.

The problem is that I can switch to a diferent view back can't switch back. When I try to switch back the simulator freezes on a black screen. I have not tested it on a real iPhone.

Here is the code.

TestMoveAppDelegate.h:

#import <UIKit/UIKit.h>

@classTestMoveViewController;

@interface TestMoveAppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) TestMoveViewController *viewController;

@end

TestMoveAppDelegate.m:

#import "TestMoveAppDelegate.h"

#import "TestMoveViewController.h"

@implementation TestMoveAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];

// Override point for customization after application launch.

if ([[UIDevicecurrentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

self.viewController = [[TestMoveViewControlleralloc] initWithNibName:@"TestMoveViewController_iPhone"bundle:nil];

} else {

self.viewController = [[TestMoveViewControlleralloc] initWithNibName:@"TestMoveViewController_iPad"bundle:nil];

}

self.window.rootViewController = self.viewController;

[self.windowmakeKeyAndVisible];

returnYES;

}

- (void)applicationWillResignActive:(UIApplication *)application

{

// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.

}

- (void)applicationDidEnterBackground:(UIApplication *)application

{

// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.

// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.

}

- (void)applicationWillEnterForeground:(UIApplication *)application

{

// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.

}

- (void)applicationDidBecomeActive:(UIApplication *)application

{

// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

}

- (void)applicationWillTerminate:(UIApplication *)application

{

// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

}

@end

TestMoveViewController.h:

#import <UIKit/UIKit.h>

@interface TestMoveViewController : UIViewController

- (IBAction)Move;

@end

TestMoveViewController.m:

#import "TestMoveViewController.h"

#import "nextView.h"

@interfaceTestMoveViewController ()

@end

@implementation TestMoveViewController

- (void)Move{

nextView * iPhoneView = [[nextView alloc] initWithNibName:nil bundle:nil];

[selfpresentViewController:iPhoneView animated:YEScompletion:NULL];

}

- (void)viewDidLoad

{

[superviewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning

{

[superdidReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}

@end

nextView.h:

#import <UIKit/UIKit.h>

@interface nextView : UIViewController

- (IBAction)Before;

@end

nextView.m:

#import "nextView.h"

#import "TestMoveViewController.h"

@interfacenextView ()

@end

@implementation nextView

- (void)Before{

TestMoveViewController * iPhoneView = [[TestMoveViewControlleralloc] initWithNibName:nilbundle:nil];

[selfpresentViewController:iPhoneView animated:YEScompletion:NULL];

}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

}

returnself;

}

- (void)viewDidLoad

{

[superviewDidLoad];

// Do any additional setup after loading the view from its nib.

}

- (void)didReceiveMemoryWarning

{

[superdidReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}

@end

plus two xib files for the interface.

Thanks in advance!
