有谁做过获得手机电量的例子吗？安卓的弄出来了 IOS的谁帮忙提供下谢谢

IOS的获取电量代码如下：

• • (int)getCurrentBatteryLevel
    {
    if ([UIApplication sharedApplication].applicationState == UIApplicationStateActive||[UIApplication sharedApplication].applicationState==UIApplicationStateInactive) {
    void *result = nil;
    object_getInstanceVariable([UIApplication sharedApplication], "_statusBar", &result);
    id status = result;
    for (id aview in [status subviews]) {
    for (id bview in [aview subviews]) {
    int batteryLevel = 0;
    if ([NSStringFromClass([bview class]) caseInsensitiveCompare:@"UIStatusBarBatteryItemView"] == NSOrderedSame&&[[[UIDevice currentDevice] systemVersion] floatValue] >= 6.0)
    {
    object_getInstanceVariable(bview, "_capacity", &result);
    batteryLevel = (int)result;
    NSLog(@"电池电量:%d",batteryLevel);
    if (batteryLevel > 0 && batteryLevel <= 100) {
    return batteryLevel;

            } else {  
                return 0;  
            }  
        }  

    }
    }

  return 0;
  }
