今日扩展程序无法从继承CoreMedia权限 [英] Today Extension Failed to inherit CoreMedia permissions from

问题描述

我正在尝试在Swift中向我的Objective-C应用添加今日扩展".我在调试器日志中不断收到此消息:Failed to inherit CoreMedia permissions from 3005: (null).编号ex. 3005每次都不同.我正在从小部件中读取NSUserDefaults，但正在读取/编写应用程序本身.我的TodayViewController中唯一的代码如下:

I am trying to add a Today Extension in Swift to my Objective-C app. I keep getting this message in my debugger log: Failed to inherit CoreMedia permissions from 3005: (null). The number ex. 3005 is different every time. I am reading from NSUserDefaults from within the widget but I am reading/writing in the app itself. The only code in my TodayViewController is this the following:

override func viewDidLoad() {
    super.viewDidLoad()

    let formatter = NSNumberFormatter()
    formatter.numberStyle = .CurrencyStyle
    totalLabel.text = formatter.stringFromNumber(0)
    coinsLabel.text = formatter.stringFromNumber(0)

    formatter.maximumFractionDigits = 0
    billsLabel.text = formatter.stringFromNumber(0)

}

func widgetMarginInsetsForProposedMarginInsets(defaultMarginInsets: UIEdgeInsets) -> UIEdgeInsets {
    return UIEdgeInsetsMake(8.0, 16.0, 8.0, 16.0)
}

func widgetPerformUpdateWithCompletionHandler(completionHandler: ((NCUpdateResult) -> Void)!) {
    // Perform any setup necessary in order to update the view.

    // If an error is encountered, use NCUpdateResult.Failed
    // If there's no update required, use NCUpdateResult.NoData
    // If there's an update, use NCUpdateResult.NewData

    completionHandler(NCUpdateResult.NewData)
}

推荐答案

我认为无法从NNNN继承CoreMedia权限"警告与

I believe the "Failed to inherit CoreMedia permissions from NNNN" warning is related to App Groups when you are creating an App Extension. Both your containing application and your app extension need to have the App Groups capability turned ON and using the same app group container ID (example: group.com.yourdomain.yourappname). App Groups are used to allow multiple apps access to shared containers and allow additional interprocess communication between apps.
