I am working on an ePub reader and it is going pretty well so far. But I need some performance running. Currently the used API to convert HTML strings to NSAttributedString objects is Apple's initialization method 

- (instancetype)initWithData:(NSData *)data options:(NSDictionary *)options documentAttributes:(NSDictionary **)dict error:(NSError **)error NS_AVAILABLE_IOS(7_0);

The only issue with this method is that, it can't be done in the background. Only on the UI/Main Thread and it takes so much running memory.

Is there some other solution that can tweak my app up a little to enhance the performance and memory utilization?

What you current code does, if by far the most efficient way. Load html ONCE and parse it to NSAttributedString's once, save them and render inside a custom view.
