Try this:

NSMutableArray *arrList = [[NSMutableArray alloc]initWithObjects:@"25-11-2016, Friday",
                           @"26-11-2016, Saturday",
                           @"27-11-2016, Sunday",
                           @"28-11-2016, Monday",
                           @"29-11-2016, Tuesday",
                           @"30-11-2016, Wednesday",
                           @"01-12-2016, Thursday",
                           @"02-12-2016, Friday",
                           @"03-12-2016, Saturday",
                           @"04-12-2016, Sunday",
                           @"05-12-2016, Monday",
                           @"06-12-2016, Tuesday",
                           @"07-12-2016, Wednesday", nil];

NSMutableArray *result = [[NSMutableArray alloc]init];
for (id element in  arrList){
    NSString *str = element;
    if ([str containsString:@"Monday"] || [str containsString:@"Sunday"]){
        [result addObject:element];
    }
}

// print result
NSLog(@"%@",result);
