How separate my NSString to two different array i.e key and value in Objective-C?

Question

Hello Guys I have one string For example

"Name=Mihir&,Age=34&,Allergy=&,Symptoms=Fever,Sore throat&,Tested=No&,State=Rhode Island"

So I need to convert this string into 2 arrays key and values like one array before = and another array after equal to.
I have done some code but I don't know what to do next!
Please see my code below:

strCustomFields = _incident.CustomFields;
NSLog(@"strCustomFields = %@",strCustomFields);
NSArray *items = [strCustomFields componentsSeparatedByString:@"&,"];

Here I have separated into array So now I have 6 arrays but now how to make my array to key and value like below?
array1 = Name,Age,Allergy,Symptoms,Tested,State
array2 = Mihir,34,,Fever Sore throat,No,Rhode Island

I don't understand why people downvote the logical code related issue? and that person has downvoted my answer as well. Stackoverflow moderator should verify these kind of upvote and downvote — Mihir Oza, May 04 '20 at 07:41

well, you may iterate through items ,split each item by '=' and put keys and values in two different NSMUtableArray

but may be it will be better to use NSDictionary to hold key-values pairs

there may be another ways depending on what you are trying to do.

Got my answer may be it's long way to get that but it works for me.

NSArray *items = [strCustomFields componentsSeparatedByString:@"&,"];
NSArray *subArr = nil;
NSMutableArray *arr1 = [[NSMutableArray alloc] init];
for (NSString* currentString in items) {
    subArr = [currentString componentsSeparatedByString:@"="];
    [arr1 addObject:[subArr objectAtIndex:0]];
    [arr1 addObject:[subArr objectAtIndex:1]];
    NSLog(@"subArr = %@", subArr);
}
NSLog(@"arr1 = %@", arr1);  
for (int i = 0; i< [arr1 count]/ 2; i++) {  
            myCustomView.lbltitle.text = [NSString stringWithFormat:@"%@", [arr1 objectAtIndex:(i *2)]];
            myCustomView.lblvalue.text = [NSString stringWithFormat:@"%@", [arr1 objectAtIndex:(i * 2) + 1]];
        }
