UIWebview Loading same html page again and again? - html

Question

I have a UIWebView in my viewcontroller, and when I tried to open an epub file it shows correctly but every epub thereafter shows the same cover page (first page) and its contents are different.
Why is this happeneing? Is there cache inside the codes?
In chapter class
- (void) loadChapterWithWindowSize:(CGRect)theWindowSize fontPercentSize:(int) theFontPercentSize
{
// [[NSURLCache sharedURLCache] removeAllCachedResponses];
fontPercentSize = theFontPercentSize;
windowSize =theWindowSize;
// NSLog(#"webviewSize: %f * %f, fontPercentSize: %d", theWindowSize.size.width, theWindowSize.size.height,theFontPercentSize);
UIWebView* webView = [[UIWebView alloc] initWithFrame:theWindowSize];
[webView setDelegate:self];
NSURLRequest* urlRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:spinePath]];
//CODE FOR IGNORING CACHE
//NSURLRequest* urlRequest ;
//urlRequest=[NSURLRequest requestWithURL:[NSURL fileURLWithPath:spinePath] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10000];
//[webView loadRequest:urlRequest];
NSLog(#"%#",spinePath);//html pahe path
[[UIApplication sharedApplication] openURL:[NSURL fileURLWithPath:spinePath]];
};

Try an experiment: instead of reloading the web view, release it and replace it with a new one (properly niling and setting delegates). If the new web view shows the same content it must be the files. If that fixes things you have now one way to fix it.
