Webpage persistent storage SDK for iOS

WebpagePersistentStorage

iOS SDK for network efficient webpage persistent caching and storage

Register auxilary global cache at some point on app start (e.g in app delegate didFinishLaunchingWithOptions)

let isOfflineHandler: (() -> Bool) = {
	return actual reachability value
    let isOffline = true  
    return isOffline
}

Provide config values for cache or nil so defaults will be used

let config = PageManager.Config(isOfflineHandler:isOfflineHandler,
    pageStorageType: nil, cacheMemoryCapacityMB: nil, cacheDiskCapacityMB: nil, cacheDiskPath: nil)

This will setup URLCache.shared instance that should not be changed

PageManager.makeSharedInstance(withConfig: config)

To save web page

let url = URL(string: "http://....")!
let pageRequest = PageRequest(with: url, options: [])

pageRequest.start(completion: { (result: PageRequest.Result) -> (Void) in

    switch result {
        case .success:
            assert(PageManager.shared.allPages().contains(url))
	    break
    
        case .failed(let error):
	        let nsError = error as NSError?
    	    print("Error \(error)")
   		break
	}
})

To load saved webpage being offline use regular UIWebView code

let request = URLRequest(url: url)
webView.loadRequest(request)
