Google 发布商合作规范最近有更新，针对出于广告相关目的而向 Google 传送用户精确位置数据的发布商，在通知和用户意见征求方面提出了新的要求。
如果该政策适用于您，以下代码段演示了您向用户告知此类数据共享的一种方式：
Swift
func presentConsentOverlayFromViewController(_ rootViewController: UIViewController) {
if (rootViewController == nil) {
return;
}
DispatchQueue.main.async {
let alert = UIAlertController(title: "Location data",
message: """
We may use your location, and share it with third parties,
for the purposes of personalized advertising, analytics,
and attribution.

""",
preferredStyle: .alert)
let alertAction = UIAlertAction(title: "OK",
style: .default,
handler: { _ in
// TODO: replace the below log statement with code that specifies how
// you want to handle the user's acknowledgement.
print("Got consent.")
}
)
alert.addAction(alertAction)
rootViewController.present(alert, animated: true, completion: nil)
}
}
// To use the above function assuming you are in a view controller:
presentConsentOverlayFromViewController(self)
Objective-C
- (void)presentConsentOverlayFromViewController:(UIViewController *)rootViewController {
if (rootViewController == nil) {
return;
}
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertController *alert = [UIAlertController
alertControllerWithTitle:@"Location data"
message: @"We may use your location, and share it with third parties,"
@"for the purposes of personalized advertising, analytics, and attribution."
@"To learn more, visit our privacy policy at https://myapp.com/privacy."
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *ok = [UIAlertAction
actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action) {
[alert dismissViewControllerAnimated:YES completion:^{
// TODO: replace the below log statement with code that specifies
// how you want to handle the user's acknowledgement.
NSLog(@"Got consent.");
}];
}];
[alert addAction:ok];
[rootViewController presentViewController:alert animated:YES completion:nil];
});
}
// To use the previous function assuming you are in a view controller:
[self presentConsentOverlayFromViewController:self];
