accessory - 从 HMService 和/或 HMAccessory 对象实例中检索公司名称

Question

我正在使用Home Kit Accessory 模拟器，我想从HMService的实例中检索配件的公司名称。但是，当我添加断点时，我看不到任何与公司名称相关的字段（我在 HMService 和HMAccessory中都进行了搜索）。

有什么建议吗？

Answer 1

您可以从HMServiceTypeAccessoryInformation 服务中获取制造商的名称，服务包含特征数组，其中有HMCharacteristicTypeManufacturer特征。

您可以使用它来显示公司名称。

- (HMCharacteristic *)characteristicForAccessory:(HMAccessory *)accessoryValue{

HMAccessory *thisAccessory = accessoryValue;
HMService *service;
for (HMService *thisService in thisAccessory.services) {
    if([thisService.serviceType isEqualToString:HMServiceTypeAccessoryInformation])    {
        service = thisService;
    }
}
HMCharacteristic *characteristic;
if (service)   {
    for (HMCharacteristic *charact in service.characteristics) {
        if ([charact.characteristicType isEqualToString:HMCharacteristicTypeManufacturer]) {
            characteristic = charact;
        }
    }
}

return characteristic;

}

使用 Characteristic 对象的 value 属性来获取制造商的名称。

看看 Raeid Saqur 的RSHomeKit框架：

您可以通过调用 service.accessory 来获取配件。然后使用：

+ (NSString *)getManufacturerNameForHMAccessory:(HMAccessory *)accessory;

+ (NSString *)getManufacturerNameForHMAccessory:(HMAccessory *)accessory {
    if (!accessory) {
        return nil;
    }
    HMCharacteristic *manufacturer = [HomeKitUtility getCharacteristicWithUUID:HMCharacteristicTypeManufacturer forAccessory:accessory];

if (manufacturer && manufacturer.value) {
    return (NSString *)manufacturer.value;
}
    return nil;
}
