Open image with Instagram

Question

Hi I need to import my edited image in Instagram , something like PhotoStudio :

I captured my image with this code :

    UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0);
    [self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

Then I need to open this screenShot with Instagram:

---

EDITED:

I implement the method like this :

    UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0);
    [self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", screenshot]];

    docFile.UTI = @"com.instagram.photo";
    [self setupDocumentControllerWithURL:igImageHookFile];

    NSURL *instagramURL = [NSURL URLWithString:@"instagram://media?id=MEDIA_ID"];
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
        [[UIApplication sharedApplication] openURL:instagramURL];
    }

    else {   
        NSLog(@"No Instagram Found");
    }
}

But I receive this output :

2012-05-05 21:55:36.842 InstantFrame[855:707] *** Assertion failure in -[UIDocumentInteractionController setURL:], /SourceCache/UIKit/UIKit-1914.84/UIDocumentInteractionController.m:1094

Instagram will be opened but does not import anything.

What you want to do is open a specially formatted url.

Here is the instragram documentation i found with a quick google search:

Here is the apple docs that describes the url scheme process. http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Introduction/Introduction.html#//apple_ref/doc/uid/TP40007891-SW1
