GlovePod是一款开源项目，允许用户在不脱下手套的情况下控制手机音乐播放。通过双击锁屏上的主页按钮显示媒体播放器，用户可以使用音量加减键切换歌曲，长按电源键来播放或暂停音乐。

国外牛人的开源工程，其说明如下

You can control music without taking off your gloves!

To use, double-tap home in the lock screen to show the media player.
Then, you can switch to the next/previous track by pressing the increase/decrease volume button.
Additionally, you can play/stop a tune by holding the power button

其中有一些很有用的函数

static BOOL isLocked()
{
return [[objc_getClass("SBAwayController") sharedAwayController] isLocked];
}

static BOOL isDimmed()
{
return [[objc_getClass("SBAwayController") sharedAwayController] isDimmed];
}

static BOOL isVisible()
{
return [[objc_getClass("SBAwayController") sharedAwayController] isShowingMediaControls];
}

static BOOL isPlaying()
{
return [[objc_getClass("SBMediaController") sharedInstance] isPlaying];
}

static BOOL isCalling()
{
return [[objc_getClass("SBTelephonyManager") sharedTelephonyManager] inCall];
}

static BOOL isPowerButtonEnabled()
{
return ((isLocked() && !isCalling()) &&
((LSiPodVisiblePowerButtonEnabled && isVisible()) ||
(LSScreenOnPowerButtonEnabled && !isDimmed() && !isVisible()) ||
(LSScreenOffPowerButtonEnabled && isDimmed())));
}

static BOOL useDefaultVolumeAction(BOOL enabled)
{
return (!isLocked() || (isLocked() && !isPlaying()) || !enabled);
}

static void $SpringBoard$invokeGPPowerButton(SpringBoard *self, SEL sel)
{
invocationGPPowerButtonTimerDidFire = YES;
[[objc_getClass("SBMediaController") sharedInstance] togglePlayPause];
}

static void startInvocationGPPowerButtonTimer()
{

SpringBoard *springBoard = (SpringBoard *)[objc_getClass("SpringBoard") sharedApplication];
invocationGPPowerButtonTimer = [[NSTimer scheduledTimerWithTimeInterval:0.7f
target:springBoard selector:@selector(invokeGPPowerButton) userInfo:nil repeats:NO] retain];
}

static void cancelInvocationGPPowerButtonTimer()
{
[invocationGPPowerButtonTimer invalidate];
[invocationGPPowerButtonTimer release];
invocationGPPowerButtonTimer = nil;
}
