Comparing 2 NSDates.
...
NSDate *date1= [formatter dateFromString:time1];
NSDate *date2 = [formatter dateFromString:time2];
if ([date2 compare:date1] == NSOrderedDescending) {
NSLog(@"date1 is later than date2");
} else if ([date2 compare:date1] == NSOrderedAscending) {
NSLog(@"date1 is earlier than date2");
} else {
NSLog(@"dates are the same");
}
UPD:
via Switch
...
NSDate *date1= [formatter dateFromString:time1];
NSDate *date2 = [formatter dateFromString:time2];
NSComparisonResult result = [date2 compare:date1];
switch(result){
case NSOrderedDescending:
NSLog(@"date1 is later than date2");
break;
case NSOrderedAscending:
NSLog(@"date1 is earlier than date2");
break;
default:
NSLog(@"dates are the same");
break;
}
