无法将图像加载到 Firebase（无法识别的选择器）

Question

（顺便说一句，我已经在 SO 上阅读了所有类似的问题，如果我的错误很愚蠢，请不要怪我）

我正在尝试上传从 imagePicker 获取并调整大小的图片

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        process(pickedImage)
    }
    dismiss(animated: true, completion: nil)
}

func process(_ image:UIImage) {
    print("start processing")
    let resized = resize(image, size: 256)
    photo.image = resized
    let ref = FIRStorage.storage().reference().child("path/to/file")
    let data = UIImageJPEGRepresentation(resized, 1.0)
    let md = ref.put(data!)
    md.observe(.success, handler: { (snap) in
        //Something onSuccess
    })
}

func resize(_ image:UIImage, size w:CGFloat) -> UIImage {
    let scale = CGFloat(w)/image.size.width
    let newHeight = image.size.height * scale
    UIGraphicsBeginImageContext(CGSize(width: w, height: newHeight))
    image.draw(in: CGRect(x: 0, y: 0, width: w, height: newHeight))
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return newImage!
}

这个抛出错误 ref.put(data!)

Answer 1

这里的问题是 queryItems 在 iOS 7 上不受支持（我假设您正在定位）。下一个客户端版本将通过使用 query 属性来支持 iOS 7。

与此同时，您可以定位 8+，它会起作用，同时等待 7 的修复。
