ios - Receipt Validation for Auto-renewable Subscription -


i confused line in apple's documentation:

for non-consumable products , auto-renewable subscriptions in ios 7 , later, use app receipt persistent record.

when says "receipt" here, referring data returned verification? or mean should read values directly thing stored @ appstoreurl (which i'm having difficult time figuring out how do).

my planned approach store important values return receipt verification in userdefaults , periodically verifying receipt make sure nothing changed. correct approach?

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
