iTellAFriend Feature IOS

What is iTellAFriend?

iTellAFriend is an iOS toolkit for displaying a preconfigued mail composer with a "Tell a Friend" template in ios apps.

Installation

To install iTellAFriend into your app, drag the iTellAFriend.h, .m into your project.

To enable iTellAFriend in your application you need to initialize iTellAFriend before the app has finished launching. The easiest way to do this is to add the iTellAFriend configuration code in your AppDelegate's, like this:

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

  [iTellAFriend sharedInstance].appStoreID = 408981381;

  return YES;
}

To present the iTellAFriend controller, use:

if ([[iTellAFriend sharedInstance] canTellAFriend]) {
  UINavigationController* tellAFriendController = [[iTellAFriend sharedInstance] tellAFriendController];
  [self presentModalViewController:tellAFriendController animated:YES];
}

LocalNotifications in iPhone

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

    [NSThread detachNewThreadSelector:@selector(fireLocalNotifications) toTarget:self withObject:nil];
 
}

-(void) fireLocalNotifications
{

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    for (int i = 0; i < 60; i++)
    {

        UILocalNotification *localNotification = [[UILocalNotification alloc] init];

        if (localNotification == nil){

            return;
}

        NSDate *notifyDate = [[NSDate date] dateByAddingTimeInterval:i * 60];

        localNotification.fireDate = notifyDate     
     
        localNotification.timeZone = [NSTimeZone defaultTimeZone];

        localNotification.alertBody = [NSString stringWithFormat:NSLocalizedString(@"This is local notification %i"), i];

        localNotification f.alertAction = NSLocalizedString(@"My Details", nil);

        localNotification.soundName = UILocalNotificationDefaultSoundName;

        localNotification.applicationIconBadgeNumber = 1;

        [[UIApplication sharedApplication] scheduleLocalNotification: localNotification];
       
        [localNotification release];
