3. 在Xcode中实现Objective-C代码

在Unity生成的Xcode项目中，添加一个Objective-C文件来实现请求跟踪权限的功能：

• 在Xcode中，创建一个新的Objective-C文件，例如TrackingAuthorization.m。

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

void RequestTrackingAuthorization() {
    if (@available(iOS 14, *)) {
        [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
            // 处理授权状态
            switch (status) {
                case ATTrackingManagerAuthorizationStatusAuthorized:
                    NSLog(@"Tracking authorized");
                    break;
                case ATTrackingManagerAuthorizationStatusDenied:
                    NSLog(@"Tracking denied");
                    break;
                case ATTrackingManagerAuthorizationStatusNotDetermined:
                    NSLog(@"Tracking not determined");
                    break;
                case ATTrackingManagerAuthorizationStatusRestricted:
                    NSLog(@"Tracking restricted");
                    break;
            }
        }];
    }
}

调用请求权限的方法

在Unity中创建一个脚本来请求跟踪权限：

public class TrackingPermission : MonoBehaviour
{
    [DllImport("__Internal")]
    private static extern void RequestTrackingAuthorization();

    public void RequestPermission()
    {
        #if UNITY_IOS
        RequestTrackingAuthorization();
        #endif
    }
}

在Unity中调用RequestPermission方法来请求跟踪权限：

public class Example : MonoBehaviour
{
    void Start()
    {
        TrackingPermission trackingPermission = new TrackingPermission();
        trackingPermission.RequestPermission();
    }
}
