我是 iOS 世界的新手，我遇到了一些我不明白的问题，我遇到了这些控制台问题:

我遇到的问题表明应用程序无法在 iOS 设备上启动，我正尝试在 iPhone XR 中启动它，正如我提到的，我是新来的，我没有得到解决方案，我阅读了一些提到我必须评论 use_frameworks! 的帖子，但这不起作用，我阅读了其他一些表明我必须取消评论 user_frameworks 的帖子，但两者都不起作用。所以，我有点迷路了。 顺便说一下，pod install 工作正常。有时我只得到 CFBundleIdentifier) does not exist 但确实如此

最佳答案

您应该在 flutter 日志中看到类似的消息:The domain/default pair of (../ios/Runner/Info, CFBundleIdentifier) does not exist

此错误意味着 Xcode 认为您的 plist 有无效格式内容。

<key>UISupportedInterfaceOrientations</key>         //<------ here is the key
<key>NSPhotoLibraryUsageDescription</key>
<key>NSCameraUsageDescription</key>
<string>Tagueo necesita usar la camara</string>
<key>NSMicrophoneUsageDescription</key>
<string>Tagueo necesita usar el microfono</string>
<array>                                            //<------ here is the value
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>UISupportedInterfaceOrientations~ipad</key>   //<------ please compare this key
<array>                                            //<------ please compare this value
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationPortraitUpsideDown</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>

你只需要将key和value移动到一起

<key>UISupportedInterfaceOrientations</key>        //<------ here is the key
<array>                                            //<------ follow with the value
   <string>UIInterfaceOrientationPortrait</string>
   <string>UIInterfaceOrientationLandscapeLeft</string>
   <string>UIInterfaceOrientationLandscapeRight</string>
</array>

关于ios - 无法在获取 CFBundleIdentifier 的 iOS 上运行 flutter 应用程序不存在，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55016250/
