However, I couldn't know where is error, I play around with my apps but show no error.

I also tried iOS 6 with iPad, no problem.

what apple feedback was 

We found that your app crashed on iPad running iOS 6, which is not in compliance with the App Store Review Guidelines.

Your app crashed on both Wi-Fi and cellular networks when we:

1. Launch the app.
2. Tap any item on main page.
3. App crashes.

What you're looking at is a stack trace, the path the program goes through your code. Each line is a function, starting at the main run loop (18) and ending at the crash (0).

The most useful parts are the functions that you have created in your app OrientalDailyiOS at frame 3.

Your app is crashing trying to access an object in an NSArray (frame 2) inside your Main_NewsDetail viewDidLoad] method (frame 3).

Edit

As I said, your app is crashing trying to access an object in an NSArray. Take a closer look at your application specifically the two lines in your viewDidLoad method that use the method that's crashing above objectAtIndex:.

font = [self.defaultsize objectAtIndex:0];

News *new = [self.singlenews objectAtIndex:0];

How are you populating self.singlenews ? What is the case were it could have no objects?
