Are you allowed by Apple to put ordinary HTML links (Amazon affiliate link) in an iPhone app?
So, an ordinary HTML affiliate link, of the form:
Just to be clear, I simply mean from the iOS app, it would open the browser from the app. (Not inside a UIWebView inside an app - simply opening the browser on the phone.) Is this allowed by Apple?
If you are trying to sell something for your app itself which it appears you are not doing, would be violating rule 11.2:
Apps utilizing a system other than the In-App Purchase API (IAP) to purchase content, functionality, or services in an App will be rejected
There is no specific rule against leading to purchase something, unless it is mandatory for your app. There is definitely no rule against putting links into your app, I have apps that have links that lead to websites.
You should be fine.
