Is there any way to load const unsigned char from plist in iOS?

Question

I have some data for my app authorisation like {0x7c, 0x1e, ...} and I need to get it in Objective-C file like:

const unsigned char ApplicationKey[] = {0x7c, 0x1e, ...};

Is there any way to get this const from plist-file?

I need this because according to this answer this answer this is the thing in NuanceHeader.m And I would like just store my AppKey in plist, neither in code.

Fundamentally a plist can contain numeric values in the form of NSNumber instances. You can create an unsigned char from those fairly easily:

NSString* pathToPlist = // Determine path to plist
NSArray* plist = [NSArray arrayWithContentsOfFile:pathToPlist];
unsigned char applicationKey[plist.count];
[plist enumerateObjectsUsingBlock:^(NSNumber* number, NSUInteger index, BOOL* stop) {
    applicationKey[index] = [number unsignedCharValue];
}];
