Is it possible to have a Conditioned `firedate` for UILocalNotification? - iphone

Question

I'm trying to have a conditioned firedate time for my local notifications, however when I tried these two ways it didn't fail but it still didn't work. So, I was wondering if I'm able to do such a thing?
Note: startTime and endTime are times from date pickers.
-(void) TEST {
NSCalendar *calendar = [NSCalendar currentCalendar];
calendar.timeZone = [NSTimeZone timeZoneWithName:#"GMT"];
NSDateComponents *components = [calendar components:NSHourCalendarUnit fromDate:[NSDate date]];
components.hour = 3;
components.minute = (components.minute + 1) % 60;
components.second = 57;
NSDate *fire = [calendar dateFromComponents:components];
UILocalNotification *notif = [[UILocalNotification alloc] init] ;
if (notif == nil)
return;
if (fire < startTime.date) {
notif.fireDate =fire ;
notif.repeatInterval= NSMinuteCalendarUnit ;
notif.alertBody = [NSString stringWithFormat: #"You are missed!"] ;
[[UIApplication sharedApplication] scheduleLocalNotification:notif] ;
}
if (fire > endTime.date) {
notif.fireDate =fire ;
notif.repeatInterval= NSMinuteCalendarUnit ;
notif.alertBody = [NSString stringWithFormat: #"You are missed!"] ;
[[UIApplication sharedApplication] scheduleLocalNotification:notif] ;
}}
OR
-(void) TEST {
NSCalendar *calendar = [NSCalendar currentCalendar];
calendar.timeZone = [NSTimeZone timeZoneWithName:#"GMT"];
NSDateComponents *components = [calendar components:NSHourCalendarUnit fromDate:[NSDate date]];
components.hour = 3;
components.minute = (components.minute + 1) % 60;
components.second = 57;
NSDate *fire = [calendar dateFromComponents:components];
UILocalNotification *notif = [[UILocalNotification alloc] init] ;
if (notif == nil)
return;
if (fire > startTime.date & fire < endTime.date) {
[[UIApplication sharedApplication] cancelAllLocalNotifications] ;
}
else {
notif.fireDate =fire ;
notif.repeatInterval= NSMinuteCalendarUnit ;
notif.alertBody = [NSString stringWithFormat: #"You are missed!"] ;
[[UIApplication sharedApplication] scheduleLocalNotification:notif] ;
}}
Thanks
If not, what would be the easiest way to make such a condition?

Answer 1

use the NSDate Compare: method instead of if(fire > startTime.date)
if([fire compare: startTime.date] == NSOrderedDescending) // if start is later in time than end
{
// do something
}
From the class reference:
If:
The receiver and anotherDate are exactly equal to each other, NSOrderedSame.
The receiver is later in time than anotherDate, NSOrderedDescending.
The receiver is earlier in time than anotherDate, NSOrderedAscending.
so for your condition
if (fire > startTime.date & fire < endTime.date) {
[[UIApplication sharedApplication] cancelAllLocalNotifications] ;
}
you can use
if([fire compare: startTime.date] == NSOrderedDescending && [fire compare: endTime.date]== NSOrderedAescending)
{
[[UIApplication sharedApplication] cancelAllLocalNotifications] ;
}
this will cancel the all local notifications if fire is between the selected start and end date
else {
// Fire the notifications
}
also have a look at the link this is similar to what you need link

Answer 2

what i, will try do do is, when the sleep Time starts,call a method eg: goingToSleep:, you can use
dispatch_later or performSelector:withObject:afterDelay: for that,
in goingToSleep:
NSArray* localNotifications = [[UIApplication sharedApplication]
scheduledLocalNotifications];
for (UILocalNotification *notification in localNotifications)
{
if([fire compare: startTime.date] == NSOrderedDescending &&
[fire compare: endTime.date]== NSOrderedAescending)
{
This is the important part
get all the properties of the notification
create a NSDictionary of those properties
Add the NSDictionary to an array
and save that array into a plist.(Save Array to Plist)
and then Cancel that notification using
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}
then after SleepTime is over
, again call a method eg: wakingUp:
then in wakingUp:
read the array of NSDictionary we saved.
again Create UILocalnotifications using those same Properties.
this way, no UILocalNotifications will trigger during sleep time. one issue can be executing those methods, if the Application is not memory.
