// Your code 
NSString *fileurl=[FILE_URL_Array objectAtIndex:indexPath.row]; 
NSArray *parts = [fileurl componentsSeparatedByString:@"/"]; 
NSString *filename = [parts lastObject]; 

NSString *extn =[filename pathExtension]; 

NSLog(@"file extn is %@",extn); 

NSURL *url = [NSURL URLWithString:fileurl]; 

// Take a web view and load the url in the web view 
NSURLRequest *request = [NSURLRequest url]; 
dispatch_async(dispatch_get_main_queue(), ^{ 

    [_webView loadRequest:request]; // UIWebView object declared globally 

});
