I need to filter the NSArray with the following conditions 1.name contains 'abc' 2.age below 18 3.weight less than 50

Answer 1

This will work but is not elegant at all.

NSMutableArray *filteredArray = [[NSMutableArray alloc]init];
for (NSDictionary *dic in myArray){

int age = [[dic objectForKey:@"age"]intValue];

     if (age < 18){

        float weight = [[dic objectForKey:@"weight"]floatValue];
        if (float < 50){

        string name = [dic objectForKey:@"name"];
        if (![string rangeOfString:@"bla"].location == NSNotFound) {
            [filteredArray addObject:dic];
         }

        }
     }

}

The other elegant solution is to use the enumeration block and predicates to check your dictionary contents, but I'm not comfortable enough in objective-C to do that.
