<h2>1. 概述<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#_1-%E6%A6%82%E8%BF%B0"></a></h2>
<p>从iOS 14.5开始，只有在获得用户明确许可的前提下，应用才可以访问用户的IDFA数据并向用户投放定向广告。在应用程序调用 <a href="https://developer.apple.com/documentation/apptrackingtransparency?language=objc"><strong>App Tracking Transparency</strong></a> 框架向最终用户提出应用程序跟踪授权请求之前，IDFA将不可用。如果某个应用未提出此请求，则读取到的IDFA将返回全为0的字符串。</p>
<h2>2. 获取广告标识IDFA<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#_2-%E8%8E%B7%E5%8F%96%E5%B9%BF%E5%91%8A%E6%A0%87%E8%AF%86idfa"></a></h2>
<h3>2.1 前提<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#_2-1-%E5%89%8D%E6%8F%90"></a></h3>
<p>开发工具需要升级到Xcode12及以上</p>
<h3>2.2 申请IDFA权限<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#_2-2-%E7%94%B3%E8%AF%B7idfa%E6%9D%83%E9%99%90"></a></h3>
<p>为了申请IDFA权限，需要info.plist里添加NSUserTrackingUsageDescription键，内容为自定义的字符串，说明为什么要获取IDFA，可根据应用本身的需求决定是否对此字符串做国际化处理。</p>
<p>xml</p>
<pre><code>//注意⚠️
//如果加上了这个，必须执行第2步，弹出IDFA权限申请，否则无法通过Appstore审核。
&lt;key&gt;NSUserTrackingUsageDescription&lt;/key&gt;
&lt;string&gt;该标识符将用于向您投放个性化广告。&lt;/string&gt;</code></pre>
<p>在应用启动后，弹出IDFA权限申请，这个弹框只会出现一次，后续如果要变更IDFA权限，需要在手机的系统设置【隐私】-【跟踪】里调整。</p>
<p>objective-c</p>
<pre><code>if (@available(iOS 14.5, *)) {
[ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
}];</code></pre>
<p>> ⚠️ 注意： 在iOS 15.0中，如果是在启动方法中调用授权，是不会弹出授权提示框的。</p>
<p>objective-c</p>
<pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions</code></pre>
<h4>解决方案<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#%E8%A7%A3%E5%86%B3%E6%96%B9%E6%A1%88"></a></h4>
<p>1、可以在这两个方法中注册 UIApplicationDidBecomeActiveNotification 通知</p>
<p>objective-c</p>
<pre><code>[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didBecomeActive) name:UIApplicationDidBecomeActiveNotification object:nil];</code></pre>
<p>然后在接受到通知后进行授权操作</p>
<p>objective-c</p>
<pre><code>- (void)didBecomeActive
{
if (@available(iOS 14.5, *))
{
[ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
}];
}
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationDidBecomeActiveNotification object:nil];
}</code></pre>
<p>2、如果你的app 不支持 Application Scene 也可以在 AppDelegate 中的 applicationDidBecomeActive 回调中进行处理</p>
<p>objective-c</p>
<pre><code>- (void)applicationDidBecomeActive:(UIApplication *)application
{
if (@available(iOS 14.5, *))
{
if([ATTrackingManager trackingAuthorizationStatus] == ATTrackingManagerAuthorizationStatusNotDetermined)
{
[ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
}];
}
}
}</code></pre>
<h2>3. 启用SKAdNetwork跟踪转化<a href="https://doc.sigmob.com/ToBid%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97/SDK%E9%9B%86%E6%88%90%E8%AF%B4%E6%98%8E/iOS/iOS14%E6%94%AF%E6%8C%81%E8%AF%B4%E6%98%8E/#_3-%E5%90%AF%E7%94%A8skadnetwork%E8%B7%9F%E8%B8%AA%E8%BD%AC%E5%8C%96"></a></h2>
<p>支持了Apple官方的 <a href="https://developer.apple.com/documentation/storekit/skadnetwork"><strong>SKAdNetwork</strong></a> 框架的三方渠道，会在获取不到IDFA的时候，正常获取转化。为了实现这个功能，需要在info.plist添加对应的SKAdNetworkItems。</p>
<p>> ⚠️ 按Apple要求，所有的SKAdNetworkIdentifier必须小写。 ⚠️ 建议对SKAdNetworkIdentifier做去重处理。</p>
