objective-c - iOS如何实现关闭自动锁屏

Question

[UIApplication sharedApplication].idleTimerDisabled = YES，设置后屏幕依旧会在一段时间后锁屏，怎么回事？

Answer 1

Put settings idleTimerDisabled的代码放到AppDelegate里的applicationDidBecomeActivein

- (void)applicationDidEnterBackground:(UIApplication *)application {
    [[UIApplication sharedApplication] setIdleTimerDisabled:NO];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [[UIApplication sharedApplication] setIdleTimerDisabled:YES];
}

Answer 2

Logically speaking, after you set idleTimerDisabled to YES, the screen should not be automatically locked in the current app. Where did you set it up? Can you give me a more detailed code?
