iphone - phonegap、iphone 和最大的坏处idleTimerDisabled

Question

阅读了很多关于如何防止 iphone 在运行我的应用程序时进入休眠状态的内容，我现在非常不高兴，因为没有任何效果..

here我读到了每 30 秒设置一个计时器的想法，将idleTimerDisabled 设置为 NO，然后设置为 YES，但我的 objC 还不是那么好。谁能告诉我如何(以及在​​哪里)？

谢谢!

编辑:这是我尝试过的代码:

- (void)applicationDidFinishLaunching:(UIApplication *)application
{   
    [ super applicationDidFinishLaunching:application ];
    //application.idleTimerDisabled = NO;
    //application.idleTimerDisabled = YES;
    //[[UIApplication sharedApplication] setIdleTimerDisabled:YES];
    [UIApplication sharedApplication].idleTimerDisabled = NO;
    [UIApplication sharedApplication].idleTimerDisabled = YES;


}

edit2:之后我尝试开始一个循环:

-(void)_timerLoop
{
    // add this function up the top.  it's what will happen when the
    // timer goes off:
    NSLog(@"Your timer went off!!!");
}


/**
 * This is main kick off after the app inits, the views and Settings are setup here.
 */
- (void)applicationDidFinishLaunching:(UIApplication *)application
{   
    [ super applicationDidFinishLaunching:application ];
    //application.idleTimerDisabled = NO;
    //application.idleTimerDisabled = YES;
    //[[UIApplication sharedApplication] setIdleTimerDisabled:YES];
    //[UIApplication sharedApplication].idleTimerDisabled = NO;
    //[UIApplication sharedApplication].idleTimerDisabled = YES;
    [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(_timerLoop) userInfo:nil repeats:YES];


}

edit3:你真的不能改变意外的反对票吗？对 stackoverflow 系统来说将是一个很好的 chnage 请求!

关于您有关使用计时器的问题:

以下是如何让计时器在 30 秒后响起(仅一次):

-(void)_jump
{
// add this function up the top.  it's what will happen when the
// timer goes off:
NSLog(@"Your timer went off!!!");
}
...
// here's how to create the timer, which will go off in 30 seconds
[NSTimer scheduledTimerWithTimeInterval:30.0
   target:self selector:@selector(_jump) userInfo:nil repeats:NO]

如果您想要两个不同的计时器，在 30 秒和 60 秒之后，只需以相同的方式制作两个即可。如果您需要有关计时器的更多帮助，请告诉我!

这再简单不过了。只需添加这一行:

application.idleTimerDisabled = YES;

在“application didFinishLaunchingWithOptions”例程中。

您将在应用委托(delegate) .m 源代码文件中找到该例程。

请务必将其添加到“return YES;”之前声明 - 一个常见的错误!所以，就像这样:

-(BOOL)application:(UIApplication *)application
            didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
    // blah blah ...

    application.idleTimerDisabled = YES;
    return YES;
    }
