iphone - UIWebView back button not getting enabled -

in application have uiwebview in need add browser functionality(user can goback,forward or reload page). achieve have used code tutorial.

in code have 1 change in viewdidload:

i loading data local html file this:

nsstring *htmlfile = [[nsbundle mainbundle] pathforresource:@"file name" oftype:@"html" indirectory:no]; nsdata *htmldata = [nsdata datawithcontentsoffile:htmlfile]; [self.webview loaddata:htmldata mimetype:@"text/html" textencodingname:@"utf-8" baseurl:[nsurl urlwithstring:@""]]; 

instead of:

nsurl* url = [nsurl urlwithstring:@"http://iosdeveloperzone.com"]; nsurlrequest* request = [nsurlrequest requestwithurl:url]; [self.webview loadrequest:request]; 

after loading initial html file if making click on page button should enabled, instead of getting enabled after second url click , not able go original home page.

please me this.

thanks.

i got answer. it's because load data webview without loadrequest. if load data webview string, won't have url go or load old page. won't store data given webview. that, need provide url this.

[self.webview loadrequest:[nsurlrequest requestwithurl:[nsurl fileurlwithpath:[[nsbundle mainbundle] pathforresource:@"file name" oftype:@"html"] isdirectory:no]]];
