archivedData(withRootObject:)' 在 iOS 12.0 中被弃用 - Swift 5 和 Flutter（swiftui支持ios12吗）

如何解决archivedData(withRootObject:)'' 在 iOS 12.0 中被弃用 - Swift 5 和 Flutter

我有一个使用 Swift 4 编写的项目（iOS 部分）。我将其更新为 5，但现在我收到了此警告。我已经尝试按照建议修复它，但每次都会遇到不同的错误。你能帮我吗？

代码

func saveData(data: BloodData) {
    if let defaults = getUserDefaults() {
      BloodData.registerClassName()
      let encodedData: Data = NSKeyedArchiver.archivedData(withRootObject: data)
      defaults.set(encodedData,forKey: dataKey)
      defaults.synchronize()
    }
  }

警告

archivedData(withRootObject:)'' was deprecated in iOS 12.0: Use +archivedDataWithRootObject:requiringSecureCoding:error: instead

代码

 func getData() -> BloodData? {
    BloodData.registerClassName()
    if let defaults = getUserDefaults(),let data = defaults.data(forKey: dataKey),let decodedData = NSKeyedUnarchiver.unarchiveObject(with: data) as? BloodData {
      return computeData(data: decodedData)
    }
    return nil
  }

警告

''unarchiveObject(with:)'' was deprecated in iOS 12.0: Use +unarchivedobjectOfClass:fromData:error: instead

这是一个计算数据函数：

private func computeData(data: BloodData) -> BloodData? {
    let today = Date()
    
    let calendar = Calendar.current

    let date1 = calendar.date(bySettingHour: 12,minute: 00,second: 00,of: calendar.startOfDay(for: data.readingDate))!
    
    let date2 = calendar.date(bySettingHour: 12,of: calendar.startOfDay(for: today))!

    let components = calendar.dateComponents([.day],from: date1,to: date2)
    let dayDiff = components.day ?? 0
    
    let newBloodData = BloodData(
      whiteCells: data.whiteCells - dayDiff,fullBlood: data.fullBlood - dayDiff,platelet: data.platelet - dayDiff,redCells1: data.redCells1 - dayDiff,redCells2: data.redCells2 - dayDiff,bloodplasma: data.bloodplasma - dayDiff,readingDate: date2
    )
    
    return newBloodData
  }

解决方法

func save(blood: BloodData,forKey defaultName: String = "BloodDataKey") {  // or forKey defaultName: String = dataKey
    guard let data = try? NSKeyedArchiver.archivedData(withRootObject: blood,requiringSecureCoding: false) else { return }
    UserDefaults.standard.set(data,forKey: defaultName)
}

func getBlood(forKey defaultName: String = "BloodDataKey") -> BloodData? {  // or forKey defaultName: String = dataKey
    guard let data = UserDefaults.standard.data(forKey: defaultName) else { return nil }
    guard let bloodData = (try? NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data)) as? BloodData else { return nil }
    return computeData(data: bloodData)
}

如何解决Android Studio 制作的 Flutter Project 可以在 iOs 上实现 在你的 iOS 设备上测试你的 Flutter iOS 应用

我对我的项目有疑问我终于从我在 Android Studio 上的 Flutter 项目中完成了，并在许多 android 设备上测试了它，现在我需要打开同一个项目并在 iOs 上测试它，我的问题是：-

1. 我是否应该更改代码或文件中的某些内容以在 Xcode 上打开它？
2. 我可以发布到 ipa 吗？

Fonts
Flutter applications may default to fonts that are standard for the target platform, but unavailable on desktop. For instance, if the target platform is TargetPlatform.iOS the Material library will default to San Francisco, which is available on macOS but not Linux or Windows.

Most applications will need to set the font (e.g., via ThemeData) based on the host platform, or set a specific font that is bundled with the application. Other widgets that doesn''t use ThemeData may not display without extra font specification (e.g., the DEBUG banner''s text).

Symptoms of missing fonts include text failing to display and/or console logging about failure to load fonts.
