I'm creating a date like this : NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"YYYY"]; NSInteger year = [[dateFormatter stringFromDate:[NSDate date]] intValue]; NSLog(@"NSInteger YEAR : %d\n", year); //minutes, hours, day and month are initialized elsewhere... NSDateComponents *comps = [[NSDateComponents alloc] init]; [comps setYear:year]; [comps setMonth:month]; [comps setDay:day]; [comps setHour:hours]; [comps setMinute:minutes]; NSDate *sampleDate =

A few threads here discuss the new iOS 6 Xcode error that pops up in the console when sending nil dates to Calendar methods: -[__NSCFCalendar components:fromDate:toDate:options:]: fromDate cannot be nil I mean really, what do you think that operation is supposed to mean with a nil fromDate? An exception has been avoided for now. A few of these errors are going to be reported with this complaint, then further violations will simply silently do whatever random thing results from the nil. The error made me chuckle a bit, but got me to thinking.... The code I've written that results in this error

The common question on stackoverflow is how to get the Day of Year from a date but how to you get the date from the Day of Year? I'm using the following code to generate the Day of Year but how to I do the converse? // Calculate Day of the Year NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSUInteger dayOfYear = [gregorian ordinalityOfUnit:NSDayCalendarUnit inUnit:NSYearCalendarUnit forDate:[NSDate date]]; setDayOfYear = dayOfYear; return setDayOfYear; Assuming you know the year you want and the actual time of the date doesn't matter and you have

I want to fire a UILocalNotification in a specific Date. If I use this code: NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [gregorian components:NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate:[NSDate date]]; [components setHour:4]; [components setMinute:0]; NSDate *fireDate = [gregorian dateFromComponents:components]; If now it's 3 pm this works fine, but it doesn't when, for example, it's 5 pm. How can I set the notification fire date to "the next 4 pm" ? NSCalendar *gregorian = [[NSCalendar

I want to create a function which results the date of next Friday but I have no plan how to do it. Has anyone a good hint to me ? E.g. Get current date using NSDate, then use 'components>fromDate:' from NSCalendar to get the NSDateComponents, then add the time difference to next Friday and create a new NSDate and Bob's is your uncle. Here is my working solution for getting the next 5 Sundays in Gregorian calendar: self.nextBeginDates = [NSMutableArray array]; NSDateComponents *weekdayComponents = [[NSCalendar currentCalendar] components:NSWeekdayCalendarUnit fromDate:[NSDate date]]; int

I have to send a DDMMYYY date from a Date to communicate with an API. NSDateComponents *dateComponents; NSCalendar *gregorian; NSDate *date; gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; dateComponents = [[NSDateComponents alloc] init]; self.date = [gregorian dateByAddingComponents:dateComponents toDate:[NSDate date] options:0]; Do I have to use the [dateComponents day] and so on? is there some method that can help me to performing that task like in PHP? Try this NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@
