I would like to send a notification using UILocalNotification when the iPhone application is in the background and display a specific view when I launch the application from that notification.
Currently, when you press Open Notification, the app starts normally and the first screen of the app (ViewController) is displayed.How do I view a specific view (SecondViewController) when I launch from a notification?
-(void)setLocalNotification:(NSString*)message
{
UILocalNotification*notification=[[UILocalNotification alloc] init];
notification.fireDate=[[NSDate date]dateByAddingTimeInterval:0];
notification.timeZone = NSTimeZone defaultTimeZone;
notification.alertBody=message;
notification.alertAction=@"Open";
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber=1;
// Register Notifications
[[UIAApplication sharedApplication] scheduleLocalNotification:notification];
}
Sample for displaying the SecondViewController in modal format.
AppDelegate.
-(BOOL) application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) launchOptions{
NSDictionary* userInfo= [launchOptions objectForKey: UIAapplicationLaunchOptionsLocalNotificationKey];
if(userInfo!=nil){
self showSecondViewController;
}
return YES;
}
- (void) application: (UIApplication*) application didReceiveLocalNotification: (UILocalNotification*) notification
{
if(application.applicationState==UIApplicationStateInactive){
self showSecondViewController;
}
}
- (void) showSecondViewController
{
UIViewController* controller=[SecondViewController alloc] init;
[self.window.rootViewController presentViewController: controller animated:YES completion:nil];
}
To view the SecondViewController designed on the Storyboard:
storyboardWithName:@"Main" depends on the appropriate Storyboard filename, so change it accordingly.(@"Main" for Main.storyboard)
As a reminder, you must set the SecondViewController to the Storyboard ID of the SecondViewController on the Storyboard.
- (void) showSecondViewController
{
UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController* controller= [storyboard instantiateViewControllerWithIdentifier:@"SecondViewController";
[self.window.rootViewController presentViewController: controller animated:YES completion:nil];
}
