How to add loop in my code

Question

I have NSMutableArray *arrList and I founded Monday objects in MutableArray *arrList. But now is static written in if condition, Look like in my code:(if ([str containsString:@"Monday"])). I want a array load place to static Monday. That mean loop wise one by one week day load in static Monday.

NSArray*loopAry = [[NSArray alloc]initWithObjects:@"Sunday",@"Monday",@"Tuesday",nil];

That is loopAry objects one by one reload to place Static Monday.

This helps to get dynamic code and reload only array in loop and get weekdays data

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"]) {
        [result addObject:element];
    }
}

// print result
NSLog(@"%@",result);
 (
"28-11-2016, Monday",
"05-12-2016, Monday"
)

You can get Array of provided day like below :

NSArray *loopAry = [[NSArray alloc]initWithObjects:@"Sunday",@"Monday",@"Tuesday",nil];

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 (NSString *strData in  arrList){
    //2nd Loop for your weekdays array.By this you will get weekdays array in result.
    for (NSString *strDay in loopAry) {
        if ([strData containsString:strDay]) {
              [result addObject:strData];
        }
    }

}

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

Hope this will help you to get week days.
