Unity Mobile Input Plugin for iOS and Android (Unity UI compatible) You can use default InputField UI component on iOS and Android without additional field above keyboard

It's deep refactor and bug fix of UnityNativeEdit (https://github.com/kmbang/UnityNativeEdit)

1. Native input field and keyboard on iOS and Android
2. Hiding additional mobile input box (Android)
3. Show "Done", "Clear" buttons (iOS)
4. Return button type: Default, Next, Done, Search, Send
5. Custom fonts support

1. Copy the files into your existing unity project asset folder
2. Make empty Gameobject and attach Plugins to your new GameObject
3. Attach MobileInputField script to your Unity UI InputField object
4. For more options set ContentType to Custom to your InputField object
5. For Android make sure your AndroidManifest.xml has the following setting

<activity android:name="com.unity3d.player.UnityPlayerNativeActivity" android:label="@string/app_name">
            ...
            <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
            ...
</activity>

6. To prevent screen slide up on Android when keyboard show, add this option to your AndroidManifest.xml

<activity ...  android:windowSoftInputMode="adjustNothing">
            ...
</activity>

1. Copy font TTF to StreamingAssets folder
2. Input font name in property instead "default"
3. You are cool

Open Demo scene and build, to try how it works
