iOS 17.2系统获取IDFA时不弹窗问题

问题：

最近公司接入三方广告归因SDK，要求使用IDFA

代码：

1. info.plist文件添加跟踪权限请求描述文字

<key>NSUserTrackingUsageDescription</key>
<string>此标识符将用于向您推荐个性化广告。</string>

2. 导入框架

#import <AppTrackingTransparency/AppTrackingTransparency.h>
#import <AdSupport/ASIdentifierManager.h>

3. 获取广告标识

- (void)applicationDidBecomeActive:(UIApplication *)application {
    if (@available(iOS 14, *)) {
            // iOS14及以上版本需要先请求权限
            [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
                // 获取到权限后，依然使用老方法获取idfa
                if (status == ATTrackingManagerAuthorizationStatusAuthorized) {
                    NSString *idfa = [[ASIdentifierManager sharedManager].advertisingIdentifier UUIDString];
