ios - Adding items to a NSMutableArray - Logic issue -

i have 5 animal objects , trying save in nsmutabledictionary. however, according code below, last animal gets saved in nsmutabledictionary.

i don't think looping correctly.

for(int = 0; < animalcount; i++) {          [allcontacts setobject:name forkey:@"name"];          [allcontacts setobject:age forkey:@"age"];          [allcontacts setobject:gender forkey:@"gender"];   } 

the output of above displays follows: (only last animal object gets displayed)

{      name = fish;      age = 6;      gender = "female";  } 

how want that, 5 animal objects saved in nsmutabledictionary can display them in uitableview.

{              name = "cow";              age = 4;              gender = "male";          },                  {              name = "dog";              age = 15;              gender = "male";          },                  {              name = "fish";              age = 6;              gender = "female";          } 

key of nsmutabledictionary unique.

what want build array , every object of array dictionary

    nsmutablearray * contentsarray = [[nsmutablearray alloc] init];     for(int = 0; < animalcount; i++) {         nsmutabledictionary * allcontacts = [[nsmutabledictionary alloc] init];         [allcontacts setobject:name forkey:@"name"];          [allcontacts setobject:age forkey:@"age"];          [allcontacts setobject:gender forkey:@"gender"];         [contentsarray addobject:allcontacts];     }
