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)
