无法加载图像火力地堡（无法识别的选择）

问题描述：

（顺便说一句，我读过，因此所有类似的问题，请不要怪我，如果我的错误是愚蠢的）无法加载图像火力地堡（无法识别的选择）

我想上传图片，我从imagePicker获取和调整，然后

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! 
}

上ref.put(data!)

可以显示完整的堆栈跟踪？ – Shubhank

答

这里的问题是，queryItems不支持iOS 7（我认为你的目标）。下一个客户端版本将通过使用query属性来支持iOS 7。

在此同时，您可以针对8+，它会正常工作，同时等待修复了7

是的，我真的针对iOS 7，但我无法在我的代码中找到queryItems。数据是Data，而md是FIRStorageUploadTask。这是Firebase SDK中的错误吗？ –

好吧，忘了它，现在我的目标是iOS8并在iOS9上测试 –

是的，这是我们SDK中的一个问题，我们将在下一个版本中解决。 –
