更新到最新的 Xcode 后，进入故事板，我无法看到实际的自定义颜色十六进制代码。它一直显示白色（FFFFFF）颜色的十六进制代码。有人可以帮我解决这个问题吗？请检查下面的屏幕截图。

我**GMImagePickerController**从照片应用中返回所选图像的列表.

代码如下.

  - (void)assetsPickerController:(GMImagePickerController *)picker  didFinishPickingAssets:(NSArray *)assetArray
     {
        NSLog(@"%@",assetArray);
        NSLog(@"GMImagePicker: User ended picking assets. Number of selected items is: %lu", (unsigned long)assetArray.count);
  }

像这样的assetArray返回结果,我从照片app中选择了3张图片

 (
"<PHAsset: 0x7fa39e02e840> 1AEEF04A-F8AB-4019-AAB5- 2875CFD8F8E3/L0/001 mediaType=1/0, sourceType=1, (425x425), creationDate=2016-02-03 13:53:17 +0000, location=0, hidden=0, favorite=0 ",

 )

现在的问题是我想得到OriginalImage并mediaType从上面的结果将图像存储到文档目录中.请帮我解决这个问题.

如何在 swift 中通过 POST 请求附加多个数据。\n作为邮递员的附加屏幕截图，当选择 x-www-form-urlencoded选项时，它工作正常\n如何使用类似正文的\'x-www-form-urlencoded\'选项附加 5 个数据。

这里的代码，

var request = URLRequest(url: urlString)\n        request.httpMethod = "POST"\n        request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")\n\n        var urlComponents = URLComponents()\n        urlComponents.queryItems = [\n            URLQueryItem(name: \xe2\x80\x9c***\xe2\x80\x9d, value: \xe2\x80\x9c***\xe2\x80\x9d),\n            URLQueryItem(name: "***", value: "***"),\n            URLQueryItem(name: "***", value: "***"),\n            URLQueryItem(name: "***", value: "***"),\n            URLQueryItem(name: "***", value: "***"),\n        ]\n        request.httpBody = urlComponents.percentEncodedQuery?.data(using: String.Encoding.utf8)\n\n        let loadDataTask = URLSession.shared.dataTask(with: request) { (data, response, error) in\n            if let _ =  error{\n                completion(false,error)\n            }\n            else if let response = …

由于 Apple 要求开发者通过 App Tracking Transparency 框架获得用户\xe2\x80\x99s 的权限，以便在 iOS 14.5 中跟踪他们或访问他们的设备\xe2\x80\x99s 广告标识符 (IDFA)

我在应用程序中使用“Firebase/Crashlytics”和“Firebase/Analytics”来获取崩溃报告。所以我将以下目的字符串添加到我的 info.plist 中

<key>NSUserTrackingUsageDescription</key> \n<string>This identifier will be used to collect Crash Data.</string>\n

但他们仍然拒绝了应用程序，原因如下。

Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage\n\n\nWe noticed that your app requests the user\xe2\x80\x99s consent to access the AppTrackingTransparency framework, but doesn\xe2\x80\x99t sufficiently explain the use of the AppTrackingTransparency framework in the purpose string.\n\nTo help users make informed decisions about how …
