iOS 设置屏幕常亮，延长休眠时间

1.打开常亮

[ [ UIApplication sharedApplication] setIdleTimerDisabled:YES] ;

2.关闭长亮

[ [ UIApplication sharedApplication] setIdleTimerDisabled:NO] ;

//****************************************************************************************

cocos2dx项目，在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {}中添加下面代码：

//设置窗口亮度大小 范围是0.1 -1.0[[UIScreen mainScreen] setBrightness:0.5];//设置屏幕常亮[UIApplication sharedApplication].idleTimerDisabled = YES;

OC// 设置屏幕常亮，默认是NO[UIApplicationsharedApplication].idleTimerDisabled =YES;// 设置窗口亮度大小，范围是0.1 - 1.0[UIScreenmainScreen] setBrightness:0.5];swfit UIApplication.shared.idleTimerDisabled =true

//设置屏幕常亮[UIApplication sharedApplication].idleTimerDisabled = YES;//取消设置屏幕常亮[UIApplication sharedApplication].idleTimerDisabled = NO;//设置屏幕常亮[[UIApplication sharedApplication] setIdleTimerDisabled:YES];//取消设置屏幕常亮[[UIApplication sharedApplication] setIdleTimerDisabled:NO];
