Quick Start to Liquid SDK for iOS & Apple Watch

This document is just a quick start introduction to Liquid SDK for iOS. You can read the full documentation at https://www.onliquid.com/documentation/ios/.

To integrate Liquid in your app, just follow the simple steps below.

Install Liquid in your project (iOS)

1. Install CocoaPods in your system

2. Open your Xcode project folder and create a file called Podfile with the following content:

   pod 'Liquid'

3. Run pod install and wait for CocoaPod to install Liquid SDK. From this moment on, instead of using .xcodeproj file, you should start using .xcworkspace.

Install Liquid in your project (watchOS)

To install Liquid for an watchOS project, you need to explicitly define the platform for each of your targets, in your Podfile, like shown below:

target 'Example' do
  platform :ios, '5.0'
  pod 'Liquid'
end

target 'ExampleApp WatchKit Extension' do
  platform :watchos, '2.0'
  pod 'Liquid'
end

target 'ExampleApp WatchKit App' do
  platform :watchos, '2.0'
  pod 'Liquid'
end

target 'Example TV App' do
  platform :tvos, '9.0'
  pod 'Liquid'
end

Start using Liquid

1. Initialize Liquid singleton

In your AppDelegate.m file initialize Liquid in application:willFinishLaunchingWithOptions: method:

#import <Liquid/Liquid.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
# ifdef DEBUG
    [Liquid sharedInstanceWithToken:@"YOUR-DEVELOPMENT-APP-TOKEN" development:YES];
# else
    [Liquid sharedInstanceWithToken:@"YOUR-PRODUCTION-APP-TOKEN"];
# endif
    // The rest of your code goes here...
}

2. Identify a user (optional)

If all your users are anonymous, you can skip this step. If not, you need to identify them and define their profile. Typically this is done at the same time your user logs in your app (or you perform an auto login), as seen in the example below:

[[Liquid sharedInstance] identifyUserWithIdentifier:@"UNIQUE-ID-FOR-USER"
                                         attributes:@{ @"gender": @"female",@"name":@"Anna Lynch" }];

The username or email are some of the typical user identifiers used by apps.

3. Track events

You can track any type of event in your app, using one of the following methods:

[[Liquid sharedInstance] track:@"clickedProfilePage"];

Or:

[[Liquid sharedInstance] track:@"boughtProduct" 
                    attributes:@{ @"productId": 123 }];

4. Configure Push Notifications and In-App Messages

To send Push Notifications or In-App Messages to your users' devices through Liquid formulas you just need to configure those three delegation methods:

// AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
    return YES;
}

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [[Liquid sharedInstance] setApplePushNotificationToken:deviceToken];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [[Liquid sharedInstance] handleRemoteNotification:userInfo forApplication:application];
}

5. Personalize your app (with dynamic variables)

You can transform any old-fashioned static variable into a "Liquid" dynamic variable just by replacing it with a Liquid method. You can use a dynamic variable like this:

NSString *text = [[Liquid sharedInstance] stringForKey:@"welcomeText" 
                                              fallback:@"Welcome to our App"];
