问题描述

在我的应用程序中，我想使用sdk 4.3打开/关闭iPhone Bluetooth.i.我对Bluetooth Manager框架有一些了解，但在4.3 ..中没有任何用处吗?还是可以通过编程方式确定蓝牙是否处于打开/关闭状态?

推荐答案

- (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
