When creating an SKStoreProductViewController
, I pass a dictionary with a parameter for the store identifier. :
@{ SKStoreProductParameterITunesItemIdentifier : @010101010 };
This value is supposed to be an NSNumber
(as it is above):
The value associated with this key is an instance of NSNumber, representing the iTunes identifier for the item you want the store to display when the view controller is presented.
But it works without complaint when I pass the value as a string:
@{ SKStoreProductParameterITunesItemIdentifier : @"010101010" };
What's going on here? Is NSNumber
automatically creating the correct number type from the string that it's given? Is this occurring in the NSNumber
or is StoreKit doing this?
Actually, thinking about it...
Initially I thought they must be converting the
NSString
into anNSNumber
before doing whatever they need to do to get the information you are looking for.However, on second thought...
I would guess that
StoreKit
is using thevalue
againstSKStoreProductParameterITunesItemIdentifier
in a string. In which case they would do something like...This will be the same whether you pass in
@12345
or@"12345"
.Possibly...
No real way to tell though.
