Share image and text message with Wechat not working in objective c

Hi I am trying to share image, URL and description with wechat user using UIActivityController but it fails to share image. I tried with following code:

 UIActivityViewController *activityView = [[UIActivityViewController alloc]   initWithActivityItems:@[@"TestMessage", [UIImage imageNamed:@"pauseImage"], [NSURL URLWithString:@"http://www.google.com"]] applicationActivities:nil];

 activityView.excludedActivityTypes = @[UIActivityTypeAssignToContact, 
 UIActivityTypeCopyToPasteboard, UIActivityTypePrint];

 [self presentViewController:activityView animated:YES completion:nil];

Getting output as shwon in image

Any help or suggestion will be appreciated. Thanks.
