CNContactStore 执行失败

CNContactStore execute fails

我正在研究如何使用联系人框架,但是创建联系人的一些相当简单的代码失败并出现意外结果。这是我的代码:

    let Store = CNContactStore()
    Store.requestAccess(for: .contacts, completionHandler:{ success, error in
        if success {
            let Contact = CNMutableContact()
            Contact.givenName = "Dave"
            Contact.familyName = "Nottage"
            let SaveRequest = CNSaveRequest()
            SaveRequest.add(Contact, toContainerWithIdentifier: nil)
            do {
                try Store.execute(SaveRequest)
                print("Success")
            }
            catch let error as NSError {
                print(error.localizedDescription)
            }
        } else {
            print("No access")
        }
    })

..这是结果:

2019-02-22 10:30:56.050344+1030 ContactsTest[30329:25254955] [default] Unable to load Info.plist exceptions (eGPUOverrides)

The operation couldn’t be completed. (Foundation._GenericObjCError error 0.)

关于可能导致此问题的原因有什么想法吗?

编辑:另请注意,这是为 macOS 10.14 SDK 编译的,并且在 macOS 10.14.3

上 运行

确保您在 Info.plist.

中添加了密钥 NSContactsUsageDescription

请参考link

Important

An iOS app linked on or after iOS 10.0 must include in its Info.plist file the usage description keys for the types of data it needs to access or it will crash. To access Contacts data specifically, it must include NSContactsUsageDescription.

答案是在Capabilities的App Sandbox部分勾选App Data的Contacts复选框,然后打开App Sandbox的开关。
