Handling multiple push notifications got error - ios

Question

I handle push notification when the screen is on by automatically push to a detailViewController. It works fine when there is one or two push notification as I can push each detailViewController on top of each other and pop it back. However, app crash when I have to pop back more than two detailViewControllers. It happens only in iOS 7+.

Answer 1

Set notification Id
- (void)application:(UIApplication *)app didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if(app.applicationIconBadgeNumber!=0)
{
app.applicationIconBadgeNumber = app.applicationIconBadgeNumber - 1;
}
NSString *aps =[NSString stringWithFormat:#"%#",[userInfo objectForKey:#"id"]];
if (app.applicationState == UIApplicationStateActive)
{
NSDictionary *dict = [NSDictionary dictionaryWithObjects:#[[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]] forKeys:#[#"notifyText"]];
[arrNotificationData addObject:dict];
[self showNotificationInActiveMode:[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]];
}
if ([aps isEqualToString:#"1"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"2"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"3"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"4"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}if ([aps isEqualToString:#"5"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
}
Use singleton class as base class and check for ID and the push and pop the view.
#interface CustomViewController ()
#end
#implementation CustomViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter]addObserver:self
selector:#selector(appBecomeActive)
name:UIApplicationDidBecomeActiveNotification
object:nil];
}
-(void)appBecomeActive
{
int val=[UserDefault getpushnotificationid];
if(val!=0){
[self checkforpushnotification];
}
}
-(void)checkforpushnotification
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
int val=[UserDefault getpushnotificationid];
[UserDefault setpushnotificationid:0];
//.: if current view is profile or setting just dismiss it.because they are present
switch (val)
{
case 1:
{
if( [self checkIfControllerExist:[DealsViewController class]])
{
return;
}else{
detailViewController *VC = (detailViewController *)[storyboard instantiateViewControllerWithIdentifier:#"VCView"];
[self.navigationController pushViewController:VC animated:YES];
}
}
break;
}
}
Now use bace class in your class
#interface detailViewController : CustomViewController
