I've never build an mobile App before and I want to create an iOS App for my blog. I'm wondering how do you put the feeds from my blog into the app?
It's against apple developer guidelines to just mirror web content to an app without adding any extra functionality. It's likely your app will get rejected
Then why there are so many apps mades by AppMakr got accepted by Apple ? Basically, they are all RSS feed apps.
What feed system are you running for your blog?
You could look into PhoneGap; a platform for building apps that can be compiled for multiple mobile platforms.
Once you have a basic understanding of how to program for the iPhone, building a simple XML parser is really easy. All you need to do is point your app to your blog's RSS feed and parse that XML to display it on your app.
Probably because they were accepted into the store before they tightened the regulations. Have a read of this thread on appmakrs own forum:
e.g an appmakr user that was denied received this from apple:
"We’ve completed the review of your app, however, we cannot post this version to the App Store because it is only a content aggregator and provides a limited set of features and functionality to users. Such apps do not comply with the App Store Review Guidelines <https://developer.apple.com/appstore/resources/approval/guidelines.html>:
12.3 Apps that are simply web clippings, content aggregators, or a collection of links, may be rejected"
