I'm making an app. Part of the app is to choose from 5 preset images.

These will be available at install and so need to be bundled with the app.

However, there is also potential to "add" more images through in app purchases.

I'm looking for the "best" way to store these images on the device with the potential to add/unlock more images.

My thoughts are that "CoreData" is too heavy for this. I could do some sort of plist thing to reference the initial five images. But then how do I add more through IAP?

With IAP, do I download the additional images upon purchase? Or should they also be bundled into the app at install and then unlocked when purchased?

Never done IAP stuff before and my previous apps all used Core-Data as they were very data heavy.

有两点需要考虑——

  1. 您想在发货后添加更多图片吗？
  2. 图像是否足够小，可以按需快速下载？

如果答案是肯定的，我会建议采用托管内容路线。Apple 甚至允许您在他们的服务器上托管内容。

否则，只需将所有内容捆绑在您的应用程序中并根据需要解锁。

关于安全性的小提示：我根本不会担心盗版，因为您无法阻止人们盗版内容/应用程序。此外，JB的人数很少（23m / 90% * 500m ~ 5%），盗版的人数更少。
