// handle image orientation 

//end

// code for save image in document directory  from camera roll
let fileManager = NSFileManager.defaultManager()
do {
    let document = try fileManager.URLForDirectory(.DocumentDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: false)
    let getFolders = try fileManager.contentsOfDirectoryAtURL(document, includingPropertiesForKeys: nil, options: .SkipsHiddenFiles)
    var maxImageNumber:Int = 0 // for get the max number image in document directory
    for folder in getFolders {
        if folder.lastPathComponent! == albumName {
            let getImagesCheck = try fileManager.contentsOfDirectoryAtURL(folder, includingPropertiesForKeys: nil, options: .SkipsHiddenFiles)
            let getImages = try fileManager.contentsOfDirectoryAtURL(folder, includingPropertiesForKeys: nil, options: .SkipsHiddenFiles)

            if getImages.count <= 0 {
                let imageUrl = folder.URLByAppendingPathComponent("Image \(getImagesCheck.count + 1).png")
                if let convertImage = UIImagePNGRepresentation(image) {
                    convertImage.writeToURL(imageUrl, atomically: true)
                }
            }else {
                // continue save images
                let getImages_else = try fileManager.contentsOfDirectoryAtURL(folder, includingPropertiesForKeys: nil, options: .SkipsHiddenFiles)

                for img in getImages_else {
                    let getImageName = img.lastPathComponent!
                    let arrayOne = getImageName.componentsSeparatedByString(".")
                    let arrayTwo = arrayOne[0].componentsSeparatedByString(" ")
                    let getImageNumber = Int(arrayTwo[1])
                    if getImageNumber! > maxImageNumber {
                        maxImageNumber = getImageNumber!
                    }
                }

                let imageUrl = folder.URLByAppendingPathComponent("Image \(maxImageNumber + 1).png")
                if let convertImage = UIImagePNGRepresentation(image) {
                    convertImage.writeToURL(imageUrl, atomically: true)
                }

            }
        }
    }

}catch {
    print(error)
}

self.dismissViewControllerAnimated(true, completion: nil)
