ios - SDK DJI 快速下载图片
<p><p>我只是尝试从我的 DJI 无人机上下载最新的访问源并将源转换为 UIImage。我认为可以做到这一点的最简单方法是拍照，然后立即从存储中下载最新照片。我将从下面的存储代码中添加下载。这是最简单的方法吗？我一直收到这个错误代码 -</p>
<pre><code>Settings parameters operation failed. (Code : -1007)
</code></pre>
<p>我进行了研究，但找不到这意味着什么 - DJI 文档仅限于几乎所有 obj-c。这里是代码 - </p>
<pre><code>@IBAction func download(_ sender: UIButton) {
let camera = self.fetchCamera()
// switch camera mode to allow for media downloads
camera?.setMode(DJICameraMode.mediaDownload, withCompletion: {(error) in
if error != nil {
self.status.text="\(error!.localizedDescription)"
}
else {
// get the media manager from the drone to gain access to the files
let manager = camera!.mediaManager!
if error != nil {
self.status.text = "State: \(manager.sdCardFileListState.rawValue)"
self.status.text = "Error refreshing list: \(error)"
}
else {
print("Refreshed file list")
print("State: \(manager.sdCardFileListState.rawValue)")
guard let files = manager.sdCardFileListSnapshot() else {
self.status.text = ("No files to download")
return
}
self.status.text = "There are files to download"
var images: = []
for file in files {
if file.mediaType == .JPEG {
self.status.text = ("Time created: \(file.timeCreated)")
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
file.fetchData(withOffset: 0, update: DispatchQueue.main, update: {(_ data: Data?, _ isComplete: Bool, _ error: Error?) -> Void in
if error != nil {
self.status.text = "State: \(manager.sdCardFileListState.rawValue)"
self.status.text = "Error downloading photo: \(error!)"
}
else {
// unwrap downloaded data and create image
if let data = data, let downloadedImage = UIImage(data: data) {
self.status.text = "Image was downloaded!"
images.append( downloadedImage )
}
}
}) // end of filedata fetch
}
}
} // end of loop
}
}
})// end of camera setMode block
}`

<p>任何帮助将不胜感激 - 谢谢</p></p>
