ios - iOS: Control access to camera roll new appear

Question

in my app I use ALAssetsLibrary to load access at photos in camera roll; The first time I start my app I see the classic message, if I want give the permission to access at the photo library or not.

But I want to test this situation in each case (allow and not allowed) but I'm not able show again this message; I tried to delete app, change number version, change bundle identifier, but nothing!

Every time I run my app it not show me this message and I have ever the permission to access in the library image; I want to test what happen if I select NO.

(I know that I can change this option in general settings, but in this case I control all in viewdidappear) I want to know what happen If I select no with that message, then is it possible show again that alert? thanks

Answer 1

好的，我想我明白了你的问题。在您的模拟器中，只需转到设置-->隐私-->照片-->您的应用程序。

每次只需关闭该开关，您就会收到该消息的提示..！

一旦用户允许或禁止您访问应用程序，该消息将永远不会再次显示，iOS 会保存此权限以不再打扰用户。

对于 iOS 模拟器，您可以重新设置以再次获取消息。
