Unity.iOS

1. Installation

For a fresh Installation

Step 1: Download the WebEngageUnityiOS.unitypackage

Step 2: Import the downloaded unitypackage into your Unity project through Assets > Import Package > Custom Package....

Step 3: Replace the framework file at Assets/Plugins/iOS/WebEngage.framework with the latest WebEngage framework. Unzip the downloaded zip file to get the framework.

Updating the native WebEngage SDK within the Unity wrapper

Replace the framework file at Assets/Plugins/iOS/WebEngage.framework with the latest WebEngage framework. Unzip the downloaded zip file to get the framework.

2. Initialization

Step 1: Add the following values in /Assets/Editor/WebEngagePostProcessBuild.cs file.

...

public class WebEngagePostProcessBuild
{
   [PostProcessBuild]
   public static void EditXcodePlist(BuildTarget buildTarget, string pathToBuiltProject)
   {
       if (buildTarget == BuildTarget.iOS)
       {
       	// Add your WebEngage license code
       	string WEBENGAGE_LICENSE_CODE = "YOUR-WEBENGAGE-LICENSE-CODE";

       	// Set debug log level
           string logLevel = "VERBOSE";
       	...
       }
   }
}

Make sure you replace YOUR_WEBENGAGE_LICENSE_CODE with your WebEngage license code. As shown below, naviagte to the Account Setup section to find your license code.

Step 2: Initialize the WebEngage SDK in your AppDelegate.m class.

#import <WebEngage/WebEngage.h>
...

-(BOOL)application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) options
{
    [[WebEngage sharedInstance] application:application didFinishLaunchingWithOptions:options];
    
    ...
}

If you are not already implementing AppDelegate.m in your Unity app, then create a new file at /Assets/Plugins/iOS/OverrideAppDelegate.m and copy the content below in that file.

#import "UnityAppController.h"
#import <WebEngage/WebEngage.h>


@interface OverrideAppDelegate : UnityAppController
@end


IMPL_APP_CONTROLLER_SUBCLASS(OverrideAppDelegate)

@implementation OverrideAppDelegate

-(BOOL)application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) options
{
    [[WebEngage sharedInstance] application:application didFinishLaunchingWithOptions:options];
    
    return [super application:application didFinishLaunchingWithOptions:options];
}

@end

3. Additional steps

Add script to remove Unwanted Architectures

Do this if not already done: Select App Target and go to Build Phase and add a Run Script step to your build steps, set it to use /bin/sh and enter the following script:

#!/bin/bash
APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
    FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
    FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
    echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

    EXTRACTED_ARCHS=()

    for ARCH in $ARCHS
    do
        echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
        lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
        EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
    done

    echo "Merging extracted architectures: ${ARCHS}"
    lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
    rm "${EXTRACTED_ARCHS[@]}"

    echo "Replacing original executable with thinned version"
    rm "$FRAMEWORK_EXECUTABLE_PATH"
    mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done

This script is for removing unsupported architectures while exporting the build OR submitting the app to the app store.
