# 附录5.Lobi资料翻译

## 1.跳转参考图

![lobi redirect](/files/-LmIAf2CBwGzI6XmRfNO)

## 2.为了使【返回】按钮游戏有效，需要游戏有scheme，并且将Scheme作为参数传递过来。

## 3.Lobi App有没有安装的检测

请检测用户手机中有没有安装Lobi app

参照下面的【代码部分】

## 4.URL（参照上面1的参考图，需要实现①和②）

### ①游戏页面 URL Scheme

lobi://game\_community?gameId=<游戏页面ID>\&backScheme=<能启动游戏的scheme>

### ②游戏页面 Web URL

<https://web.lobi.co/game/><游戏页面ID>?backScheme=<能启动游戏的scheme>

## 【代码部分】

参考地址： <https://github.com/kayac/Lobi/wiki/Lobi-OfficialCommunity>

### 1.事前准备

* iOS9以后，为了启动Lobi App，需要在Info.plist的LSApplicationQueriesSchemes中添加lobi
* Android不需要额外操作

### 2.实例Demo

iOS部分

```
- (void)openOfficialCommunity
{
	// 请将<游戏页面ID>替换为Lobi团队给出的正确ID
	NSString *const officialCommunityUrlString       = @"https://web.lobi.co/special/community-lp/<游戏页面ID>";
	NSString *const officialCommunityUrlSchemeString = @"lobi://game_community?gameId=<游戏页面ID>";

	// Lobi初回起動時にゲームページヘ遷移するためにペーストボードを利用する。
 	UIPasteboard.generalPasteboard.string = @"{\"co.lobi.pasteboard.urlscheme\":\"lobi://game_community?gameId=<游戏页面ID>\"}";

 	NSURL *officialCommunityUrl       = [NSURL URLWithString:officialCommunityUrlString];
 	NSURL *officialCommunityUrlScheme = [NSURL URLWithString:officialCommunityUrlSchemeString];
     
 	if ([[UIApplication sharedApplication] canOpenURL:officialCommunityUrlScheme]) {
 		[[UIApplication sharedApplication] openURL:officialCommunityUrlScheme];
 	}
 	else {
 		[[UIApplication sharedApplication] openURL:officialCommunityUrl];
 	}
}

        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));

Unity Demo

```
// コミュニティ遷移用ブリッジ
public class CommunityBridge : object {
 
	private void OpenOfficialCommunity_android() {
		using (AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))

			try {
				launchIntent = packageManager.Call<AndroidJavaObject>("getLaunchIntentForPackage", "com.kayac.nakamap");
			} catch(System.Exception ex) {
				// nothing to do
			}
            
			if (launchIntent == null) {
				// Lobi is not installed
				Application.OpenURL("https://web.lobi.co/special/community-lp/<ゲームページID>");
			} else {
				// Lobi is installed
				launchIntent.Dispose();
				using (AndroidJavaObject gamePageIntent = new AndroidJavaObject("android.content.Intent"))
				using (AndroidJavaClass uri = new AndroidJavaClass("android.net.Uri")) {

					currentActivity.Call ("startActivity", gamePageIntent);
				}
			}
		}
	}
 
	public static void officialCommunityHandler() {
		#if UNITY_ANDROID && !UNITY_EDITOR
		OpenOfficialCommunity_android();
		#endif
		#if ((UNITY_IOS || UNITY_IPHONE) && ! UNITY_EDITOR)
		OpenOfficialCommunity_ios();

	}
 
	#if ((UNITY_IOS || UNITY_IPHONE) && ! UNITY_EDITOR)
	[DllImport("__Internal")]
	private static extern void OpenOfficialCommunity_ios();
	#endif
}
```

Unity iOS用的接口

```
void OpenOfficialCommunity_ios()
{
	// Lobiチームよりご案内した<ゲームページID>を設定してください。
	NSString *const officialCommunityUrlString       = @"https://web.lobi.co/special/community-lp/<ゲームページID>";
