ios - 类型 'String' 的值没有成员 'stringByAppendingPathComponent'

Question

这个问题已经有答案了:

stringByAppendingPathComponent is unavailable (11 个回答)

已关闭 5 年前。

我刚刚将项目转换为 Swift 3，但出现错误 directory.path行:

Error: Value of type 'String' has no member 'stringByAppendingPathComponent'.

我已经尝试过let realmPath = (directory as NSString).stringByAppendingPathComponent相反，我收到以下错误:

Cannot convert value of type 'URL' to type 'NSString' in coercion.

override func awake(withContext context: Any?) {
    super.awake(withContext: context)

    let directory: URL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.RazvanJulian.app")!
    let realmPath = directory.path.stringByAppendingPathComponent("db.realm") /* ERROR */

    RLMRealm.setDefaultRealmPath(realmPath)
    realmToken = RLMRealm.default().addNotificationBlock { note, realm in
        self.reloadTableData()
    }
    reloadTableData()
}

请检查并告诉我。

提前谢谢您!

stringByAppendingPathComponent 在 Swift 3 中变成了 appendingPathComponent。试试这个:

directory.appendingPathComponent("component")
