Question

I have set up a sharedCache using ASIHttprequest and it is created from the xml I parse in my subview. I was woundering if I can then access that sharedCache from my mainview to do a few things things that will speed my tables up?

any idea, suggestions, thoughts of examples would be greatly appreciated.

There’s already a sharedCache provided by ASIDownloadCache. It’s visible anywhere in your application (assuming you #import "ASIDownloadCache.h"), so you should be able to call [ASIDownloadCache sharedCache] and use it.

EDIT: To use several caches is not too tricky. Create a separate class which is included by both your main view and your subview. In there, define a method to return one or more ASIDownloadCache objects, and provide an implementation, similar to this:

---

DownloadCaches.h

#import "ASIDownloadCache.h"

@interface DownloadCaches : NSObject

    + (ASIDownloadCache *)imageCache;

@end

---

DownloadCaches.m

#import "DownloadCaches.h"

@implementation DownloadCaches
    static ASIDownloadCache *imageCache = nil;

    + (ASIDownloadCache *)imageCache
    {
        if(imageCache == nil)
        {
            imageCache = [[ASIDownloadCache alloc] init];
            // set imageCache-specific options here
        }

        return imageCache;
    }

@end

You only ever need to call [DownloadCaches imageCache] and it will be initialised if not already, and then returned to you.
