Get all days of any month with objective-c

Question

A seemingly simple question...how can I return a list of days for any specified month?

NSDate *today = [NSDate date]; //Get a date object for today\'s date
N         


        

Answer 1

You can make your date with pretty much any string:

NSDate *date = [NSDate dateWithNaturalLanguageString:@"January"];

Then the rest of your code will work as-is to give you back the NSRange for the number of days in January.

Answer 2

Carl's answer works on Mac. The following works on Mac or iPhone (no dateWithNaturalLanguageString: available there).

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [[[NSDateComponents alloc] init] autorelease];

// Set your year and month here
[components setYear:2015];
[components setMonth:1];

NSDate *date = [calendar dateFromComponents:components];
NSRange range = [calendar rangeOfUnit:NSCalendarUnitDay inUnit:NSCalendarUnitMonth forDate:date];

NSLog(@"%d", (int)range.length);
