set fireDate of UILocalNotification

I'm using this app here it works fine with me but I want to insert the fireDate of local notification manually instead of using the datePicker.

notif.fireDate = [datePicker date];

How can I insert date (day, month, year, hours and minutes) manually?

I tried the following

NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *dateComps = [[NSDateComponents alloc] init];
[dateComps setDay:10];
[dateComps setMonth:3];
[dateComps setYear:2013];
[dateComps setHour:4];
[dateComps setMinute:45];
NSDate *itemDate = [calendar dateFromComponents:dateComps];

int minutesBefore = 2;
notif.fireDate = [itemDate addTimeInterval:-(minutesBefore*60)];

but it not works with me.

thanks in advance.

Using NSDateFormatter you can convert directly from a NSString to a NSDate. Here's an example: 

NSDateFormatter* myFormatter = [[NSDateFormatter alloc] init];
[myFormatter setDateFormat:@"MM/dd/yyyy"];
NSDate* myDate = [myFormatter dateFromString:@"8/26/2012"];
NSLog(@"%@", myDate);

EDIT
If you want time too

NSString *str =@"3/15/2012 9:15 PM";
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:@"MM/dd/yyyy hh:mm a"];
NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
[formatter setTimeZone:gmt];
NSDate *date = [formatter dateFromString:str];

NSLog(@"%@",date);

Follow this link for more info SO Answer

And for localNotification just implement this too after fire date

UIApplication *app=[UIApplication sharedApplication];
[app scheduleLocalNotification:localNotification];

How about using addTimeInterval?

UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = [itemDate addTimeInterval:-(minutesBefore*60)]; 

 //minutesBefore will be type of int and itemDate would be of NSDate type.

Update 1:

After searching little I found out addTimeInterval is deprecated in iOS 4 and further. Instead you should use dateByAddingTimeInterval. 

 localNotif.fireDate = [itemDate dateByAddingTimeInterval:-(minutesBefore*60)];

Providing negative value to dateByAddingTimeInterval will fire notification minutes earlier to the itemDate.
