ios - inApp purchase, dowload free products -


i implementing inapp features download hosted content feature. products free unlimited time. each product have 1 download associated , audio file.

  1. is possible start download without user see dialog buy free product. first user must give apple id password, see dialog buy free product , dialog product succesfully purchased.than download can requested. since products free can somehow download reuested without user see confiramtion dialogs , messages , start download imedietly.

  2. if item purchased/downloaded user see message buy free item again. know restore functionalities, need track downloaded items , in case start download restore state.

thanks!

1) yes, can download without dialogs. product detail using store kit, , if product price free (0), download item without processing purchase request storekit.

code request product detail:

kproductsrequest *productsrequest = [[skproductsrequest alloc] initwithproductidentifiers: [nsset setwitharray:productidentifiers]];  // keep strong reference request. self.request = productsrequest; productsrequest.delegate = self; [productsrequest start];

// skproductsrequestdelegate protocol method

- (void)productsrequest:(skproductsrequest *)request      didreceiveresponse:(skproductsresponse *)response {     self.products = response.products;      (nsstring *invalididentifier in response.invalidproductidentifiers) {         // handle invalid product identifiers. or check product looking dozens has identifier here      }     (skproduct *product in self.products)      {          //for example, product looking has identifier  "com.product.free"                    if([product.productidentifier isequaltostring:@"com.product.free"] && [product.price comparewithint:0])          {                // startdownloading without purchase            }      } }

2) if have non-consumable inappt purchase, must provide option restore. downloading, can write own logic. check if item downloaded , re-download if not available.
