iOS: how to filter array from another array based on parameter value

Question

I have an NSArray (DataArray) whose response is as follows:

  {
"id": "17",
"item_name": "Chivito",
"item_price": "88.00",
"item_status": "Y",
"is_admin": "0",
"item_quantity": "120",
"status": 0
},
  {
"id": "14",
"item_name": "Doughnut",
"item_price": "50.00",
"item_status": "Y",
"is_admin": "0",
"item_quantity": "100",
"status": 1
},
  {
"id": "37",
"item_name": "Drink test ",
"item_price": "80.00",
"item_status": "Y",
"is_admin": "0",
"item_quantity": "12",
"status": 1
},

I have to create another filtered array of only those object whose status value is "1" Please help me how to do it

Answer 1

try this out

array.filter{(object) -> Bool in 
  if let object = object as NSDictionary {
    if let status = object["status"] as? Int {
      return status == 1
    }
  }
  return false
}

Answer 2

Referring to @Hady ans, In Objective-C you can do it as. Forgive if there are any formatting/syntax issues. I am away from my system.

NSMutableArry *filteredArray = [NSMutableArray alloc]init];

for (i=0;i<dataArray.count;i++)
{
   if([dataArray[i][@"status"] isEqualToNumber:[NSNumber numberWithInt: 1]])      //if(dataArray[i]["status"] == 1)
    {
      [filteredArray addObject:dataArray[i]];
     }
 }

Hope it helps.. Happy Coding!!

Answer 3

Try predicate its easy and less looping .

NSPredicate *sizePredicate = [NSPredicate predicateWithFormat:@"status == %@",[NSNumber numberWithBool: YES]];

NSMutableArray * filteredSizeArray = [self.arrayFilter filteredArrayUsingPredicate:sizePredicate].copy;

Answer 4

Try:

OBJECTIVE-C:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.status == %d",1];
    NSArray *filtered = [DataArray filteredArrayUsingPredicate:predicate];
    NSLog(@"RESULT: %@", filtered);

Answer 5

You can try this:

NSPredicate *prediate = [NSPredicate predicateWithFormat:@"status == %d",1];
arrResult = [myArray filteredArrayUsingPredicate:prediate];
