ios - UIWebView Copy Cache Data For Offline View -


i want copy cache data database(sqlite/coredata) can view while offline (without internet) " reading list in safari ". read code @ xcode uiwebview download , save html file , show following:- 

- (void)viewdidload {      nsurl *url = [nsurl urlwithstring:@"http://livedemo00.template-help.com/wt_37587/index.html"];        //[webview loadrequest:requrl];       // determile cache file path     nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);     nsstring *filepath = [nsstring stringwithformat:@"%@/%@", [paths objectatindex:0],@"index.html"];         // download , write file      nsdata *urldata = [nsdata datawithcontentsofurl:url];     [urldata writetofile:filepath atomically:yes];      // load file in uiwebview     [webview loadrequest:[nsurlrequest requestwithurl:[nsurl fileurlwithpath:filepath]]];              [super viewdidload]; }

but problem code not show images while offline .

so thought saving data cache database option.can share sample code copy website content along images database.

thank in advance

you may used asiwebpagerequest , example given here

or

if reachability got connectivity 

nscachedurlresponse* response = [[nsurlcache sharedurlcache]                                       cachedresponseforrequest:[webview request]]; nsdata* data = [response data];

store data in locally , use whenever got reachability offline.
