有没有办法在iOS中以编程方式打开和关闭蓝牙和/或wifi？ [英] Is there a way to toggle bluetooth and/or wifi on and off programmatically in iOS?

问题描述

我正在寻找一种在iOS 4.x设备（iPhone和iPad）上打开和关闭状态之间切换蓝牙和wifi的简单方法。

I am looking for an easy way to toggle both bluetooth and wifi between on and off states on iOS 4.x devices (iPhone and iPad).

我是我在不同的位置和使用场景之间移动时不断切换这些功能，现在需要多次点击并访问Settings App。我希望创建一个简单的应用程序，它存在于Springboard上，我可以点击它，它会关闭wifi，如果它打开，反之亦然，然后立即退出。与用于切换蓝牙状态的应用程序类似。

I am constantly toggling these functions as I move between different locations and usage scenarios, and right now it takes multiple taps and visits to the Settings App. I am looking to create a simple App, that lives on Springboard, that I can just tap and it will turn off the wifi if it's on, and vice versa, then immediately quit. Similarly with an App for toggling bluetooth’s state.

我有开发人员SDK，并且对Xcode和iOS开发很满意，所以很高兴能够编写所需的代码来创建应用程序。我只是不知道哪个私有或非私有API具有简单切换这些设施状态所需的功能。

I have the developer SDK, and am comfortable in Xcode and with iOS development, so am happy to write the required code to create the App. I am just at a loss as to which API, private or not, has the required functionality to simply toggle the state of these facilities.

因为这是非常个人化的痒，我无意尝试销售应用程序或在应用程序商店中获取它，因此符合关于API使用的应用程序指南是没有问题的。我不想做的是越狱设备，因为我想保留核心软件。

Because this is scratching a very personal itch, I have no intent to try and sell the App or get it up on the App store, so conforming with App guidelines on API usage is a non-issue. What I don’t want to do is jailbreak the devices, as I want to keep the core software as shipped.

任何人都可以指点我的一些示例代码或更多信息实现这一目标，因为我的Google-fu让我失望，如果信息出现在4.x设备上，我就找不到它。

Can anyone point me at some sample code or more info on achieving this goal, as my Google-fu is letting me down, and if the information is out there for 4.x devices I just can’t find it.

推荐答案

感谢Matt Farrugia（Twitter上的@mattfarrugia）我正在寻找的答案是：

Thanks to Matt Farrugia (@mattfarrugia on Twitter) the answer I was looking for was:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

#if TARGET_IPHONE_SIMULATOR
    exit( EXIT_SUCCESS ) ;
#else
    /* this works in iOS 4.2.3 */
    Class BluetoothManager = objc_getClass( "BluetoothManager" ) ;
    id btCont = [BluetoothManager sharedInstance] ;
    [self performSelector:@selector(toggle:) withObject:btCont afterDelay:0.1f] ;
#endif
    return YES ;
}

#if TARGET_IPHONE_SIMULATOR
#else
- (void)toggle:(id)btCont
{
    BOOL currentState = [btCont enabled] ;
    [btCont setEnabled:!currentState] ;
    [btCont setPowered:!currentState] ;
    exit( EXIT_SUCCESS ) ;
}
#endif

您还需要链接Gamekit框架，只需将此代码添加到新的Xcode项目并在设备上运行。这样做会创建一个应用程序，可以打开和关闭蓝牙。

You need to link against the Gamekit framework as well, but simply add in this code to a new Xcode project and run on the device. Doing so creates a 1-tap App that toggles Bluetooth on and off.
