UILocalNotification and UISwitch remember state - ios

Question

I made an UISwitch, and when it is switched on, my app sends 10 notifications with a "repeat interval". It works all fine. But the problem is, when I want to save (remember) the state of my UISwitch and load it, the UILocalNotification aren't being sent anymore.
This is my code:
For the save of the UISwitch state and notification launch:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
BOOL test= [[NSUserDefaults standardUserDefaults] boolForKey:#"switch"];
NSLog(#"%#",test?#"YES":#"NO");
[self.alarmSwitch setOn:test animated:YES];
}
- (void) switchIsChanged:(UISwitch *)paramSender{
if ([paramSender isOn]){
[[NSUserDefaults standardUserDefaults] setBool:self.alarmSwitch.on forKey:#"switch"];
[[NSUserDefaults standardUserDefaults] synchronize];
notification1 = [[UILocalNotification alloc]init];
notification1.fireDate = [NSDate dateWithTimeIntervalSinceNow:5.0];
[notification1 setAlertBody:#"U moet uw voeten controleren!"];
[[UIApplication sharedApplication] scheduleLocalNotification:notification1];
notification1.fireDate = [NSDate dateWithTimeIntervalSinceNow:10.0];
[[UIApplication sharedApplication] scheduleLocalNotification:notification1];
}
}
How can I save the state of the UISwitch in another way in order to get this work? Or is there another solution to fix this?

Your switchIsChanged: method isn't going to be firing when you set the on state programatically. I would recommend moving the code that handles the notifications out of the switchIsChanged: method. Example:
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
BOOL test= [[NSUserDefaults standardUserDefaults] boolForKey:#"switch"];
NSLog(#"%#",test?#"YES":#"NO");
[self.alarmSwitch setOn:test animated:YES];
// initially detect if we should fire the bnotifications
if ([self.alarmSwitch isOn]) {
[self fireNotifications];
}
}
-(void)switchIsChanged:(UISwitch *)paramSender{
[[NSUserDefaults standardUserDefaults] setBool:paramSender.on forKey:#"switch"];
[[NSUserDefaults standardUserDefaults] synchronize];
if ([paramSender isOn]){
[self fireNotifications];
}
}
-(void)fireNotifications {
notification1 = [[UILocalNotification alloc]init];
notification1.fireDate = [NSDate dateWithTimeIntervalSinceNow:5.0];
[notification1 setAlertBody:#"U moet uw voeten controleren!"];
[[UIApplication sharedApplication] scheduleLocalNotification:notification1];
notification1.fireDate = [NSDate dateWithTimeIntervalSinceNow:10.0];
[[UIApplication sharedApplication] scheduleLocalNotification:notification1];
}
Note: you may have to make sure that the notifications aren't firing more than once which may cause bugs since viewWillAppear: can be called multiple times.
