ios 禁止自动锁屏

如果不希望iOS设备自动锁屏，可以使用以下方式来保持屏幕一直开着。
代码 加在application didFinishLanchingWithOptions
[[UIApplication sharedApplication] setIdleTimerDisabled: YES];
或者
[UIApplication sharedApplication].idleTimerDisabled = YES;
 
[[UIApplication sharedApplication] setIdleTimerDisabled: YES];
或者

[UIApplication sharedApplication].idleTimerDisabled = YES;
