NSArray* sortedDateList = [dateList sortedArrayUsingComparator:^(NSDate* dateOne, NSDate* dateTwo) {
    return [dateOne compare:dateTwo];
}];

`return [dateOne compare:dateTwo]` would be better. – Cyrille Dec 12 '11 at 09:28

You can use NSMutableArray's method sortUsingComparator, and write your comparison block using NSDate's compare method.

If you are using NSDate object this should be easy:

NSDate *date1 = ...;
NSDate *date2 = ...;
NSDate *date3 = ...;

NSArray *dates = [NSArray arrayWithObjects:date1,date2,date3,nil];

NSArray *sortedArray = [dates [anArray sortedArrayUsingSelector:@selector(compare:)];

NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"beginDate" ascending:TRUE];
[myMutableArray sortUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]];
[sortDescriptor release];

Use this sort descriptor for sorting array of dates
