App Trace功能实战：一键拉起、快速安装与免提写邀请码的应用实践

// DeepLink路由分发器
class TraceRouter : AppRouter() {
    override fun handle(uri: Uri) {
        when(uri.path) {
            "/trace/campaign" -> {

                Analytics.log("deep_link_launch", mapOf("type" to "campaign"))
            }
            "/trace/invite" -> {
                // 处理邀请逻辑
            }
        }
    }

// SceneDelegate处理Universal Links
func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,

    let router = TraceRouter()
    if router.canHandle(url: url) {
        router.handle(url: url)
    }
}

// 安装引导页关键逻辑
const tryLaunchApp = () => {
    // 尝试Scheme唤起
    window.location.href = 'ourapp://launch';
    
    // 超时检测（动态调整超时时间）
    const timeout = getDevicePerformanceTimeout(); 
    setTimeout(() => {
        if (!isAppForeground()) {
            // 智能跳转应用商店
            const storeUrl = getStoreUrlByOS();
            redirectWithFallback(storeUrl);
        }
    }, timeout);
};

// 设备性能自适应
function getDevicePerformanceTimeout() {
    const ram = navigator.deviceMemory || 2;
    return ram > 3 ? 800 : 1500; // 高端设备缩短等待
}
