iOS14以后新增了广告标识【IDFA】的权限，获取方法有所改变，具体如下：

1>.获取：
if (@available(iOS 14.0,*)) {

    [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
        if (status == ATTrackingManagerAuthorizationStatusAuthorized) {
            NSString *idfa = [[ASIdentifierManager sharedManager].advertisingIdentifier UUIDString];
        }else {
            NSLog(@"请打开广告追踪");
        }
    }];
    
} else {
    
    if ([[ASIdentifierManager sharedManager]isAdvertisingTrackingEnabled]) {
        
        NSString *idfa = [[ASIdentifierManager sharedManager].advertisingIdentifier UUIDString];
    } else {
        NSLog(@"请打开广告追踪权限");
    }
}

2>.配置权限：
