i want to post image on pinterest using this link but i change coding Little bit according to my own Requirement here is my MainClass code 

- (void)pInterest {
      UIImage *myImage;
      myImage=imgView.image;
      WebViewController *webViewController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:nil];
      webViewController.mypimage = myImage;
     [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentModalViewController:webViewController animated:YES];
}

So after passing image to my WebViewController now my WebViewController class code is 

- (void)viewDidLoad {
     //imageview.image=mypimage;
     [super viewDidLoad];
     NSString *description = @"Post your description here";

     // Generate urls for button and image
     NSString *sUrl = [NSString stringWithFormat:@"http://d30t6wl9ttrlhf.cloudfront.net/media/catalog/product/Heros/mypimage"];
     // NSLog(@"URL:%@", sUrl);
     NSString *protectedUrl = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(__bridge CFStringRef)sUrl, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
     NSLog(@"Protected URL:%@", protectedUrl);
     NSString *imageUrl = [NSString stringWithFormat:@"\"%@\"", sUrl];
     NSString *buttonUrl = [NSString stringWithFormat:@"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%@&description=%@\"", protectedUrl, description];

     NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000];
     [htmlString appendFormat:@"<html> <body>"];
     [htmlString appendFormat:@"<p align=\"center\"><a href=%@ class=\"pin-it-button\" count-layout=\"horizontal\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></a></p>", buttonUrl];
     [htmlString appendFormat:@"<p align=\"center\"><img width=\"400px\" height = \"400px\" src=%@></img></p>", imageUrl];
     [htmlString appendFormat:@"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"];
     [htmlString appendFormat:@"</body> </html>"];
     [mywebview setBackgroundColor:[UIColor clearColor]];
     [mywebview loadHTMLString:htmlString baseURL:nil];
     [mywebview setOpaque:NO];
}

When i use the above coding my webview show no image and my webview looks like below screenshow
enter image description here enter image description here

When i assign the same image instance to image view in WebViewController its working imageview.image=mypimage;

So can some one suggest me why my webveiw not show the image.Thanks.

    use this code…… Hope it will help you.

    - (IBAction)pinit:(id)sender {
    [self postToPinterest];
}

- (IBAction)closeWebVIew:(id)sender {
    [webViewPinterest setHidden:YES];
}

- (NSString*) generatePinterestHTML {
   NSString *description = @"Post your description here";
 NSURL* sUrl = [NSString stringWithFormat:@"http://4.bp.blogspot.com/-w4oTZjlpgwo/T5_pi-KJPuI/AAAAAAAAAoM/rKm3E0XCbgY/s1600/red_rose_flower3.jpg"];// pass your link here with your image name

    NSLog(@"URL:%@", sUrl);
   NSString *protectedUrl = ( NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,( CFStringRef)sUrl, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
    NSLog(@"Protected URL:%@", protectedUrl);
    NSString *imageUrl = [NSString stringWithFormat:@"\"%@\"", sUrl];
    NSString *buttonUrl = [NSString stringWithFormat:@"\"http://pinterest.com/pin/create/button/?url=www.flor.com&media=%@&description=%@\"", protectedUrl, description];

    NSMutableString *htmlString = [[NSMutableString alloc] initWithCapacity:1000];
    [htmlString appendFormat:@"<html> <body>"];
    [htmlString appendFormat:@"<p align=\"center\"><a href=%@ class=\"pin-it-button\" count-layout=\"horizontal\"><img border=\"0\" src=\"http://assets.pinterest.com/images/PinExt.png\" title=\"Pin It\" /></a></p>", buttonUrl];
    [htmlString appendFormat:@"<p align=\"center\"><img width=\"400px\" height = \"400px\" src=%@></img></p>", imageUrl];
    [htmlString appendFormat:@"<script type=\"text/javascript\" src=\"//assets.pinterest.com/js/pinit.js\"></script>"];
    [htmlString appendFormat:@"</body> </html>"];
    return htmlString;
}

- (void) postToPinterest {
    NSString *htmlString = [self generatePinterestHTML];
    NSLog(@"Generated HTML String:%@", htmlString);
    webViewPinterest.backgroundColor = [UIColor clearColor];
    webViewPinterest.opaque = NO;
    if ([webViewPinterest isHidden]) {
        [webViewPinterest setHidden:NO];
    }
    [webViewPinterest loadHTMLString:htmlString baseURL:nil];
    //[webViewPinterest loadHTMLString:@"<img src=images.png>" baseURL:nil];
}

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    return YES;
}

- (void)webViewDidStartLoad:(UIWebView *)webView {
    [busyIndicator startAnimating];
}

-(void)webViewDidFinishLoad:(UIWebView *)webView {
    [busyIndicator stopAnimating];
}
