ios - Copy objects from NSArray to another NSArray -


i'm making ios app using vksdk. want copy data response.json[@"items"](it's nsarray,response.json nsdictionary) nsarray. here code:

vkrequest * getwall = [vkrequest requestwithmethod:@"wall.get" andparameters:@{vk_api_owner_id : @"1"} andhttpmethod:@"get"]; [getwall executewithresultblock:^(vkresponse * response) {     _vk_array=[[nsarray alloc]initwitharray:response.json[@"items"]];      nslog(@"%@",_vk_array);//shows null      nslog(@"%@",response.json[@"items"]);//shows ok } errorblock:^(nserror * error) {     if (error.code != vk_api_error) {         [error.vkerror.request repeat];     }     else {         nslog(@"vk error: %@", error);     } }];

i trying use code

_vk_array=response.json[@"items"]

but still shows "null". doing wrong?

ps:

nslog(@"%hhd",([response.json[@"items"] iskindofclass:[nsarray class]]));//shows 1

hi can use copy array object array.

nsarray *copyarray = [nsarray arraywitharray:yourarray];

thanks
