快速将图像转换为BASE64字符串 [英] Converting Image to BASE64 String in swift

问题描述

我正在尝试转换用户从其照片或从相机拍摄的新照片中选择的图像.我能够将图像转换为base64字符串，但问题是它花费了太多时间并打印了一个长的无限字符串

I am trying to convert the Image which is picked by user either from his Photos or Take New from Camera. I am able to convert the image into base64 string but the problem is that it takes too much time and prints a long infinite string

这是我得到的String的输出

Here is the output of String which i am getting

这是我的代码:

// Image picker from Gallery
    func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
        imagePicker.dismissViewControllerAnimated(true, completion: nil)
        profileImage.image = image

    }

    // Image Picker from Camera

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        imagePicker.dismissViewControllerAnimated(true, completion: nil)
        profileImage.image = info[UIImagePickerControllerOriginalImage] as? UIImage

        addPicBtn.setImage(nil, forState: .Normal)

        let imageData:NSData = UIImagePNGRepresentation(profileImage.image!)!
        let imageStr = imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
        print(imageStr)


    }

推荐答案

实际上，转换不会花费时间，但要进行打印，会花费更多时间，所以请不要打印...

Actually it will not take time to convert but for printing, it will take more time so don't print it...
