您可以在应用程序委托的 didFinishLaunchingWithOptions 中执行此操作。您需要在此方法中执行以下操作:
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
....
//Get the version number of the application using this technique: http://stackoverflow.com/questions/458632/how-can-my-iphone-app-detect-its-own-version-number
NSString version = [self appVersion];
//Because you only want to display the notification on first launch so have a flag in user defaults to track that. Also note that you need to include this in your registerDefaults and set to NO
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
BOOL alreadyDisplayedNotification = [defaults boolForKey:@"alreadyDisplayedNotificationOnStartForVersion"];
if ([version isEqualToString:@"VersionForWhichYouWantNotification"] && !alreadyDisplayedNotification) {
//Display Notification...
// Set the flag in user default to track that notification has been displayed
[defaults setBool:YES forKey:@"alreadyDisplayedNotificationOnStartForVersion"];
}
.....
}
