How to track how many times an iPhone app is opened?

Question

I am building an iphone app and would like to keep track of how many times it has been opened so that I can prompt the user to do certain actions after it has been opened X number of times. I have thought about storing a variable in Core Data which I update every time it is opened, but this seems like a waste since it is a singleton data, not multiple instances of an object. What is the best way to store data like this and access it without slowing down the app opening time?

You can store it user defaults. Here is the code: Please apply some condition ...

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

..... [self countOpen];

}

-(void) countOpen

{

int _coutn= 0; _count= [[[NSUserDefaults standardUserDefaults] objectForKey:@"AppCount"] intValue];

[[NSUserDefaults standardUserDefaults] setObject:[NSString stringFormat:@"%d",_count+1] forKey:@"AppCount"];

}
