Flutter App 在 iOS 上启动时崩溃。 Xcode 错误“无法识别的选择器”
[英]Flutter App crashes on iOS on start. Xcode error "unrecognized Selector"
问题描述
使用 flutter 构建的应用程序现在拒绝在 iOS 上运行，但我一个月前工作过。 该应用程序构建但打开时（模拟器和 iPhone）它在白屏半秒后崩溃。
该错误似乎出现在 AppDelegate.swift 文件中。 Xcode 在
“@obj class AppDelegate：FlutterAppDelegate {”行：线程 1：异常：“-[__NSArrayM boolValue]：无法识别的选择器发送到实例 0x60000099a430”
import Flutter
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}

我曾尝试清理 Xcode（产品 -> 清理构建文件夹）、颤动（颤动清理）。 错误在于没有将所有与 iOS 相关的文件推送到 GitHub。 Podfile、Podfile.lock 没有被推送。 当我尝试使用较新的 iOS 文件重建它时，正在运行的旧应用程序版本现在已损坏。
由于我对 Xcode 没有太多经验，因此我很难理解错误。 感谢您的帮助！

对我来说，似乎 IsIosEmbeddedViewsPreviewEnabled() 破坏了构建。 知道如何从这里继续吗？

应用程序再次在 iOS 上运行。 有帮助的是：
flutter create myProjectPath
重新创建/修复的文件：
iOS/Podfile ios/Podfile.lock ios/Runner.xcodeproj/project.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings ios/Runner/Info.plist
希望这可能会在将来对某人有所帮助。
