アプリのバージョンを取得する

iOS

Swift

let version: String! = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String

let build: String! = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") as! String

Objective-C

NSString *version = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

NSString *build = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

Android

Java

public static int getVersionCode(Context context){
    PackageManager pm = context.getPackageManager();
    int versionCode = 0;
    try{
        PackageInfo packageInfo = pm.getPackageInfo(context.getPackageName(), 0);
        versionCode = packageInfo.versionCode;
    }catch(PackageManager.NameNotFoundException e){
        e.printStackTrace();
    }
    return versionCode;
}

public static String getVersionName(Context context) {
    PackageManager pm = context.getPackageManager();
    String versionName = "";
    try {
        PackageInfo packageInfo = pm.getPackageInfo(context.getPackageName(), 0);
        versionName = packageInfo.versionName;
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
    return versionName;
}

もしくは

int versionCode = BuildConfig.VERSION_CODE;
String versionName = BuildConfig.VERSION_NAME;

Kotlin

fun getVersionCode(context: Context): Int {
    val pm = context.packageManager
    var versionCode = 0
    try {
        val packageInfo = pm.getPackageInfo(context.packageName, 0)
        versionCode = packageInfo.versionCode
    } catch (e: PackageManager.NameNotFoundException) {
        e.printStackTrace()
    }
    return versionCode
}

fun getVersionName(context: Context): String {
    val pm = context.packageManager
    var versionName = ""
    try {
        val packageInfo = pm.getPackageInfo(context.packageName, 0)
        versionName = packageInfo.versionName
    } catch (e: PackageManager.NameNotFoundException) {
        e.printStackTrace()
    }
    return versionName
}

もしくは

val versionCode : Int = BuildConfig.VERSION_CODE
val versionName : String = BuildConfig.VERSION_NAME

Androidにて、BuildConfigでの取得方法を追記しました。
