Store NSMutableArray in NSUserDefaults

I am trying to save NSMutableArray

in the NSUserDefaults

following way but I get the following error.

(lldb) po pOrderElements
<__NSArrayM 0x174256b90>(
{
    category = 1;
    imagePath = "products/chicken-kabob.png";
    name = "Baked Chicken";
    price = "5.49";
}
)

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:pOrderElements forKey:@"tableViewData"];
[userDefaults synchronize];

      

        
        
        
      

    

Application terminated due to uncaught exception "NSInvalidArgumentException", reason: "Attempt to insert a non-proprietary list of objects ({category = 1; id =" "; imagePath =" products / chicken-kabob.png "; name =" Baked chicken " ; price = "5.49";}) for tableViewData '
