What could be wrong?
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(#"Button Clicked!");
return YES;
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{

}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{

Answer 1

Got the solution. Got an NSZombie wherein I was releasing the object and then trying to access it. Got the desired result after I made use of Instruments to find out the NSZombie.
