ios simulator black screen with status bar

ios simulator black screen with status bar

I am new to objective c and i'm making my first app, a single-view app.
However, when i run my program the ad that is supposed to appear(im using
revMob)appears. But when i exit the ad i get a black screen with a blue
status bar at the top
I tried many things such as setting my main view controller as initial
view controller, restarting my computer, changing/removing debugger,
resetting the ios simulator, etc.
My xcode version is 4.6 and my OS is mac OSX 10.8.4
i dont want to delete Xcode and i also dont want to remove ads because
that is my only source of income.
Here is my code:
appdelegate.m:
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
[RevMobAds startSessionWithAppID:@"myappid"];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]
bounds]] autorelease];
[self.window makeKeyAndVisible];
return YES;
}
- (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.
RevMobFullscreen *ad = [[RevMobAds session] fullscreen];
[ad loadWithSuccessHandler:^(RevMobFullscreen *fs) {
[fs showAd];
NSLog(@"Ad loaded");
} andLoadFailHandler:^(RevMobFullscreen *fs, NSError *error) {
NSLog(@"Ad error: %@",error);
} onClickHandler:^{
NSLog(@"Ad clicked");
} onCloseHandler:^{
NSLog(@"Ad closed");
}];
}
- (void)applicationWillTerminate:(UIApplication *)application
{
// Called when the application is about to terminate. Save data if
appropriate. See also applicationDidEnterBackground:.
}
- (void)dealloc
{
[_window release];
[super dealloc];
}
