iOS 8.x Support Needed

[tateu]

UIImage kitImageNamed returns null and kCFCoreFoundationVersionNumbers are needed for iOS 8.x versions.

As a quick fix, in UIStatusBarCustomItemView.mm, I have been using:

UIImage* image_color = [$UIImage imageWithContentsOfFile: [NSString stringWithFormat: @"/System/Library/Frameworks/UIKit.framework/%@_%@_Color.png", isLockscreen?  @"LockScreen" : isBlack ? @"Black" : @"White", itemName]];
UIImage* image_base = image_color ? 0 : [$UIImage imageWithContentsOfFile: [NSString stringWithFormat: @"/System/Library/Frameworks/UIKit.framework/%@.png", expandedName_default]];
