I tried to get a NSDate from a NSString with UNKNOWN format, So I wrote a function like below

-(void)dateFromString:(NSString*)string {

    NSE

You have to use NSDateFormatter. Try replace your if statement with:

if ([match resultType] == NSTextCheckingTypeDate) {
   NSDate *dateAfter = [match date];
   NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
   [dateFormatter setDateFormat:@"yyyy-MM-dd 'at' HH:mm"];
   NSString *formattedDateString = [dateFormatter stringFromDate:dateAfter];
   NSLog(@"After: %@", formattedDateString);
}

If you want to display it in different format you have to change this line to required format:

[dateFormatter setDateFormat:@"yyyy-MM-dd 'at' HH:mm"];

If you want it to match your first example change it to:

[dateFormatter setDateFormat:@"EEEE, MMMM dd, yyyy 'at' HH:mm:ss a zzzz"];
