使用Firebase时使用未解析的标识符“FIRDatabase” [英] Use of unresolved identifier 'FIRDatabase' when using Firebase

问题描述

Xcode告诉我， FIRDatabase 不是标识符。
我的代码：

 导入UIKit 
导入Firebase 
 
 @UIApplicationMain 
 class AppDelegate：UIResponder，UIApplicationDelegate {
 
 var window：UIWindow？ 
 
 func application（application：UIApplication，didFinishLaunchingWithOptions launchOptions：[NSObject：AnyObject]？） - > Bool {
 FIRApp.configure（）
 FIRDatabase.database（）。persistenceEnabled = true //使用未解析的标识符FIRDatabase'
 return true 
} 
} 
  

我正在使用：
$ b Xcode 7.2。 1，
Firebase 3.0.2，
OSX 10.10.5

Podfile内容：

  source'https://github.com/CocoaPods/Specs.git'
 platform：ios，'8.0'
 use_frameworks！ 
 
 target'myapp'do 
 pod'IQKeyboardManagerSwift'，'< = 4.0.0'
 pod'JSQMessagesViewController'，'< = 7.3.1'
 pod'Firebase'
 end 
  

解决方案

您需要添加

  pod'Firebase / Database'
  

到您的pod文件，如此处所述

您可以找到哪个窗格包含哪个功能
Pods and Features p>

Xcode tells me that FIRDatabaseis not an identifier. My code:

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        FIRApp.configure()
        FIRDatabase.database().persistenceEnabled = true // Use of unresolved identifier 'FIRDatabase'
        return true
    }
}

I am using:

Xcode 7.2.1, Firebase 3.0.2, OSX 10.10.5

Podfile content:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target 'myapp' do
pod 'IQKeyboardManagerSwift', '<= 4.0.0'
pod 'JSQMessagesViewController', '<= 7.3.1'
pod 'Firebase'
end

解决方案

You need to add

  pod 'Firebase/Database'

to your pod file as explained here

https://firebase.google.com/docs/database/ios/start
