# iOS Installation
2017-03-02 12:50:09 +00:00
2017-04-27 11:18:12 +00:00
## 1) Setup google-services.plist and dependencies
2017-04-06 12:11:43 +00:00
Setup the `google-services.plist` file and Firebase ios frameworks first; check out the relevant Firebase docs [here](https://firebase.google.com/docs/ios/setup#frameworks).
2017-04-27 11:18:12 +00:00
### 1.1) Initialisation
2017-04-06 12:11:43 +00:00
Make sure you've added the following to the top of your `ios/[YOUR APP NAME]]/AppDelegate.m` file:
2017-03-02 12:50:09 +00:00
`#import <Firebase.h>`
2017-03-02 12:50:09 +00:00
and this to the `didFinishLaunchingWithOptions:(NSDictionary *)launchOptions` method:
`[FIRApp configure];`
2017-04-27 11:18:12 +00:00
## 2) Link RNFirebase
2017-04-06 12:11:43 +00:00
There are multiple ways to install RNFirebase depending on how your project is currently setup:
### 2.1) You already use Cocoapods and have React Native installed as a pod
Simply add the following to your `Podfile`:
2017-03-02 12:50:09 +00:00
```ruby
2017-04-06 12:11:43 +00:00
# Required by RNFirebase - you should already have some of these from step 1.
2017-03-23 13:40:18 +00:00
pod 'Firebase/Auth'
pod 'Firebase/Analytics'
pod 'Firebase/AppIndexing'
pod 'Firebase/Core'
pod 'Firebase/Crash'
pod 'Firebase/Database'
pod 'Firebase/DynamicLinks'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'Firebase/Storage'
pod 'RNFirebase', :path => '../node_modules/react-native-firebase'
2017-03-02 12:50:09 +00:00
```
### 2.2) You're not using Cocoapods or don't have React Native installed as a pod (Automatic install)
React native ships with a `link` command that can be used to link the projects together, which can help automate the process of linking our package environments.
```bash
react-native link react-native-firebase
```
#### cocoapods
We've automated the process of setting up with cocoapods. This will happen automatically upon linking the package with `react-native-cli`.
Update the newly installed pods once the linking is done:
```bash
cd ios && pod update --verbose
```
**NOTE: You need to use the `ios/[YOUR APP NAME].xcworkspace` instead of the `ios/[YOUR APP NAME].xcproj` file from now on.**

### 2.3) You're not using Cocoapods or don't have React Native installed as a pod (Manual install)
If you prefer not to use `react-native link`, we can manually link the package together with the following steps, after `npm install`:
**A.** In XCode, right click on `Libraries` and find the `Add Files to [project name]`.
![Firebase.xcodeproj add to files](https://cloud.githubusercontent.com/assets/5347038/24249673/0fccdbec-0fcc-11e7-83eb-c058f8898525.png)
**B.** Add the `node_modules/react-native-firebase/ios/Firebase.xcodeproj`
![Firebase.xcodeproj in Libraries listing](https://cloud.githubusercontent.com/assets/21329063/24249440/9494e19c-0fd3-11e7-95c0-c2baa85092e8.png)
**C.** Ensure that the `Build Settings` of the `RNFirebase.xcodeproj` project is ticked to _All_ and it's `Header Search Paths` include both of the following paths _and_ are set to _recursive_:
1. `$(SRCROOT)/../../react-native/React`
2. `$(SRCROOT)/../node_modules/react-native/React`
3. `${PROJECT_DIR}/../../../ios/Pods`
![Recursive paths](https://cloud.githubusercontent.com/assets/21329063/24250349/da91284c-0fd6-11e7-8328-6008e462039e.png)
**D.** Setting up cocoapods
Since we're dependent upon cocoapods (or at least the Firebase libraries being available at the root project -- i.e. your application), we have to make them available for RNFirebase to find them.
Using cocoapods is the easiest way to get started with this linking. Add or update a `Podfile` at `ios/Podfile` in your app with the following:
```ruby
# Required by RNFirebase
pod 'Firebase/Auth'
pod 'Firebase/Analytics'
pod 'Firebase/AppIndexing'
pod 'Firebase/Core'
pod 'Firebase/Crash'
pod 'Firebase/Database'
pod 'Firebase/DynamicLinks'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'Firebase/Storage'
```
Then you can run `(cd ios && pod install)` to get the pods opened.
**NOTE: You need to use the `ios/[YOUR APP NAME].xcworkspace` instead of the `ios/[YOUR APP NAME].xcproj` file from now on.**
## 3) Cloud Messaging (optional)
If you plan on using [Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging/) then, you need to:
**NOTE: FCM does not work on the iOS simulator, you must test is using a real device. This is a restriction enforced by Apple for some unknown reason.**
### 3.1) Set up certificates
Follow the instructions at https://firebase.google.com/docs/cloud-messaging/ios/certs
### 3.2) Enable capabilities
In Xcode, enable the following capabilities:
1) Push Notifications
2017-05-11 08:54:23 +00:00
2) Background modes > Remote notifications
### 3.3) Update `AppDelegate.h`
Add the following import:
`@import UserNotifications;`
Change the interface descriptor to:
`@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>`
### 3.4) Update `AppDelegate.m`
Add the following import:
`#import "RNFirebaseMessaging.h"`
Add the following to the `didFinishLaunchingWithOptions:(NSDictionary *)launchOptions` method after `[FIRApp Configure]`:
`[[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];`
Add the following methods:
2017-05-02 09:56:33 +00:00
```objectivec
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
willPresentNotification:(UNNotification *)notification
withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
[RNFirebaseMessaging willPresentNotification:notification withCompletionHandler:completionHandler];
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
withCompletionHandler:(void (^)())completionHandler
{
[RNFirebaseMessaging didReceiveNotificationResponse:response withCompletionHandler:completionHandler];
}
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
[RNFirebaseMessaging didReceiveLocalNotification:notification];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo
fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
[RNFirebaseMessaging didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
}
```
