设备音量（Camera volume）

调整设备的声音大小（Adjust the sound volume of the device）

获取设备音量（Get device volume）

从app缓存中拿到 KHJDeviceManager 类的对象：（Get objects of class KHJDeviceManager from the app cache:）

KHJBaseDevice *dDevice = [[KHJAllBaseManager sharedBaseManager] searchForkey:Uid];
if (dDevice) {
  // volume:取值范围在[0, 100]，即 0 - 100%（volume: The value range is [0, 100], that is 0-100%）
    [dDevice.mDeviceManager getDeviceVolume:^(int volume) {

    }];
}

或者（or）

KHJDeviceManager *manager = [[KHJDeviceManager alloc] init];
[manager createKHJCameraBase:Uid];
if (manager) {
  // volume:取值范围在[0, 100]，即 0 - 100%（volume: The value range is [0, 100], that is 0-100%）
  [manager getDeviceVolume:^(int volume) {

    }];
}

设置设备音量（Set device volume）

从app缓存中拿到 KHJDeviceManager 类的对象：（Get objects of class KHJDeviceManager from the app cache:）

KHJBaseDevice *dDevice = [[KHJAllBaseManager sharedBaseManager] searchForkey:Uid];
if (dDevice) {
    // volume:取值范围在[0, 100]，即 0 - 100%（volume: The value range is [0, 100], that is 0-100%）
    [dDevice.mDeviceManager setDeviceVolume:volume returnBlock:^(BOOL success) {

    }];
}

或者（or）

KHJDeviceManager *manager = [[KHJDeviceManager alloc] init];
[manager createKHJCameraBase:Uid];
if (manager) {
  // volume:取值范围在[0, 100]，即 0 - 100%（volume: The value range is [0, 100], that is 0-100%）
  [manager setDeviceVolume:volume returnBlock:^(BOOL success) {

    }];
