iOS开发如何获取同一AppGroup下所有关联应用的bundleID列表

苹果没有提供公开API可以直接查询指定App Group ID关联的所有应用Bundle ID，原查询关联Bundle ID的实现思路无法实现，可使用以下替代方案满足卸载判定需求。

方案逻辑：

• 所有接入通用库、使用同一App Group的App，每次启动/进入前台时，自动向App Group共享的UserDefaults中写入自身Bundle ID对应的最新活跃时间戳
• 需判定应用是否卸载时，读取共享UserDefaults中存储的所有Bundle ID活跃记录，时间戳超过设定阈值的即可判定为已卸载（应用被卸载后无法再更新时间戳）

Swift 实现代码 #

// 上报当前App最新活跃状态，建议在App启动/进入前台时调用
func updateAppActiveStatus(appGroupID: String) {
    guard let sharedDefaults = UserDefaults(suiteName: appGroupID),
          let currentBundleID = Bundle.main.bundleIdentifier else { return }
    sharedDefaults.set(Date().timeIntervalSince1970, forKey: "active_\(currentBundleID)")
    sharedDefaults.synchronize()
}

// 获取所有存活的关联App Bundle ID列表，阈值默认7天可自定义
func getActiveAssociatedBundleIDs(appGroupID: String, expireThreshold: TimeInterval = 7*24*3600) -> [String] {
    guard let sharedDefaults = UserDefaults(suiteName: appGroupID) else { return [] }
    let allKeys = sharedDefaults.dictionaryRepresentation().keys
    var activeBundleIDs = [String]()
    let currentTimestamp = Date().timeIntervalSince1970
    for key in allKeys {
        guard key.hasPrefix("active_"),
              let activeTimestamp = sharedDefaults.object(forKey: key) as? Double,
              currentTimestamp - activeTimestamp <= expireThreshold else { continue }
        activeBundleIDs.append(String(key.dropFirst(7)))
    }
    return activeBundleIDs
}

Objective-C 实现代码 #

// 上报当前App最新活跃状态，建议在App启动/进入前台时调用
- (void)updateAppActiveStatusWithAppGroupID:(NSString *)appGroupID {
    NSUserDefaults *sharedDefaults = [[NSUserDefaults alloc] initWithSuiteName:appGroupID];
    NSString *currentBundleID = [NSBundle mainBundle].bundleIdentifier;
    if (!sharedDefaults || !currentBundleID) return;
    [sharedDefaults setDouble:[NSDate.date timeIntervalSince1970] forKey:[NSString stringWithFormat:@"active_%@", currentBundleID]];
    [sharedDefaults synchronize];
}

// 获取所有存活的关联App Bundle ID列表，阈值默认7天可自定义
- (NSArray<NSString *> *)getActiveAssociatedBundleIDsWithAppGroupID:(NSString *)appGroupID expireThreshold:(NSTimeInterval)expireThreshold {
    if (expireThreshold <= 0) {
        expireThreshold = 7 * 24 * 3600;
    }
    NSUserDefaults *sharedDefaults = [[NSUserDefaults alloc] initWithSuiteName:appGroupID];
    if (!sharedDefaults) return @[];
    NSMutableArray *activeBundleIDs = [NSMutableArray array];
    NSTimeInterval currentTimestamp = [NSDate.date timeIntervalSince1970];
    for (NSString *key in sharedDefaults.dictionaryRepresentation.allKeys) {
        if (![key hasPrefix:@"active_"]) continue;
        NSTimeInterval activeTimestamp = [sharedDefaults doubleForKey:key];
        if (currentTimestamp - activeTimestamp <= expireThreshold) {
            [activeBundleIDs addObject:[key substringFromIndex:7]];
        }
    }
    return activeBundleIDs.copy;
}

• 全程不需要在info.plist中新增任何配置，仅依赖已配置的App Group权限即可运行
• 可根据业务需求调整阈值，需要更高精度的卸载判定可将阈值设置为1天，同时在App每次进入前台时都调用上报活跃状态的接口
• 应用被卸载后重装会重新写入对应活跃记录，不会出现误判
