可以使用以下代码行打开/关闭蓝牙,但是由于它访问Apple的私有框架,因此您的App可能会在App中被拒绝商店推送
it is possible to switch on/off the Bluetooth by using the below lines of code , but since it access private frameworks of Apple, your App may reject in App store push
- (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:1.0f] ;
#endif
return YES ;
}
#if TARGET_IPHONE_SIMULATOR
#else
- (void)toggle:(id)btCont
{
BOOL currentState = [btCont enabled] ;
[btCont setEnabled:!currentState] ;
[btCont setPowered:!currentState] ;
}
#endif
