Body
copied!<p>I am trying to export a photo from my application to Instagram, using this code:</p> <pre><code>// Capture Screenshot UIGraphicsBeginImageContextWithOptions(self.view.frame.size,self.view.opaque,0.0); [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); NSData *imageData = UIImageJPEGRepresentation(image, 1.0); NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"]; NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]]; dic = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:igImageHookFile]]; dic.UTI = @"com.instagram.photo"; dic.annotation = [NSDictionary dictionaryWithObject:@"my caption" forKey:@"InstagramCaption"]; NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"]; if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) { [[UIApplication sharedApplication] openURL:instagramURL]; } else { NSLog(@"No Instagram Found"); } </code></pre> <p>But it is not working. It crashes with the following error:</p> <blockquote> <p>2013-01-19 20:40:41.948 Ayat[12648:c07] <strong>* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*</strong> -[NSURL initFileURLWithPath:]: nil string parameter'</p> </blockquote> <p>I am not sure I'm properly:</p> <p>1- Saving jpgpath as the screenshot I took .</p> <p>2- Passing the "dic" document to Instagram.</p>

Querying!
