for(UIView *subView in reportSubviews) {
    [subView removeFromSuperview];
}
// Get path to specified DOC document
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"exampleForDoc" ofType:@"doc"];
if (filePath == NULL) {
    NSLog(@"Document is not found");
    return;
}

NSURL *url = [NSURL fileURLWithPath:filePath];
// Create a DOC document view
ProceduralDocumentView *documentView = [[ProceduralDocumentView alloc] initWithFrame:self.view.bounds];
//Set document URL for view
[documentView setDocumentURL:url];
// Get document contents view
UIWebView *webview = [documentView webView];
// Get view background color
UIColor *color = [webview backgroundColor];
CGColorRef colorRef = [color CGColor];
// Get view background color alpha component
CGFloat alpha = CGColorGetAlpha(colorRef);
// Display view background color alpha component in the development environment console
NSLog(@"View background color alpha component: %f", alpha);
