iOS如何以编程方式读取设备的屏幕自动锁定超时时间？

Question

I'm creating a method to send debug info to the support team for one of my apps. I have method calls like these:

 NSString* appVersion = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];
 NSString* build = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];;
 NSString* iOSVersion = [[UIDevice currentDevice] systemVersion];;

An additional requirement is to understand how our internal timeout interacts with the device's screen auto lock timer. To do so we need to compare our internal timeout with the ipad screen lock timer.

Is there a way to get the device's auto-lock time that is defined in device settings? See screen below for the number I'm trying to read

Answer 1

This isn't possible. Following link has some work around for this. Basically you can get the idle time in your app till the screen goes off which should be the same as device' auto-lock time.

Answer 2

目前，它是不可能得到了在设备设置中定义的设备的自动锁定时间。

Answer 3

Currently not possible, you can measure it yourself by calling and timing the following two functions

- (void)applicationWillResignActive:(UIApplication *)application

- (void)applicationDidBecomeActive:(UIApplication *)application
