推荐答案

您可以使用以下代码（我刚刚通过检查内容找到了这个我的iPad上的 / var / mobile / Library / Preferences / 目录：

You can use the following code (I just found this out by examining the contents of the /var/mobile/Library/Preferences/ directory on my iPad):

NSDictionary *pref = [[NSUserDefaults standardUserDefaults] persistentDomainForName:@"com.apple.timed"];
BOOL autotime = [[pref objectForKey:@"TMAutomaticTimeEnabled"] boolValue];
NSLog(@"Automatic time is %@", autotime ? @"enabled" : @"disabled");

这些密钥没有文档，你可能不应该在AppStore应用程序中使用它们。但是，您可以在内部应用程序或软件中安全地将它们用于越狱设备。

These keys are undocumented and you should probably not use them in an AppStore app. You can, however, safely use them in in-house apps or softwares for jailbroken devices.
