if you want to just send the image without clipping you should set image size of 640 x 640 or the application crash

This my swift code

 var instagramURL = NSURL(string: "instagram://app")!
        if UIApplication.sharedApplication().canOpenURL(instagramURL) {
            var documentDirectory = NSHomeDirectory().stringByAppendingPathComponent("Documents")
            var saveImagePath = documentDirectory.stringByAppendingPathComponent("Image.igo")
            var imageData = UIImagePNGRepresentation(self.bestScoreShareView.takeSnapshot(W: 640, H: 640))
            imageData.writeToFile(saveImagePath, atomically: true)
            var imageURL = NSURL.fileURLWithPath(saveImagePath)!
           docController  = UIDocumentInteractionController()
            docController.delegate = self
            docController.UTI = "com.instagram.exclusivegram"
            docController.URL = imageURL
            docController.presentOpenInMenuFromRect(CGRectZero, inView: self.view, animated: true)

        } else {
            println("instagram not found")
        }

extension for take shapshot from uiview

extension UIView {
    func takeSnapshot(#W: CGFloat, H: CGFloat) -> UIImage {
        var cropRect = CGRectMake(0, 0, 600, 600)
        UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)
        drawViewHierarchyInRect(self.bounds, afterScreenUpdates: true)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        image.imageWithNewSize(CGSizeMake(W, H))
        return image
    }
}

extension for set image size

extension UIImage {
     func imageWithNewSize(newSize:CGSize) ->UIImage {
        UIGraphicsBeginImageContext(newSize)
        self.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))

        let newImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();
        return newImage
    }
}
