1. Home and Device Management

1.1. Home management

After the user logs in successfully, needs to use TuyaSmartHomeManager to request the information of the home list, and then initialize one of the TuyaSmartHome to obtain the details of the home and manage and control the devices in the home. Reference document Home management.

1.2. Device management

All functions related to device management correspond to the TuyaSmartDevice class, which needs to be initialized with the device id. Incorrect device id may cause initialization to fail and return nil. Reference document Device management.

Always obtain the device list through the home, and get the device id from the device list of the home to initialize the TuyaSmartDevice object to avoid the situation where the home data is not synchronized and TuyaSmartDevice initialization fails.

1.3. Camera device

After obtaining the device list, you can determine whether it is a smart camera device based on the type of device. If it is a smart camera device, you can create a camera object based on the information in TuyaSmartDeviceModel.

1.3.1. Determine if it is a smart camera

You can determine the type of device according to the category property ofTuyaSmartDeviceModel. The category of the smart camera is sp.

Example

ObjC

[[TuyaSmartHomeManager new] getHomeListWithSuccess:^(NSArray<TuyaSmartHomeModel *> *homes) {
        [homes enumerateObjectsUsingBlock:^(TuyaSmartHomeModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                TuyaSmartHome *home = [TuyaSmartHome homeWithHomeId:obj.homeId];
                [home getHomeDetailWithSuccess:^(TuyaSmartHomeModel *homeModel) {
                        [home.deviceList enumerateObjectsUsingBlock:^(TuyaSmartDeviceModel * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                    if ([obj.category isEqualToString:@"sp"]) {
                        NSLog(@"%@ is a smart camera", obj.name);
                    }
        }];
        } failure:^(NSError *error) {

        }];
    }];
} failure:^(NSError *error) {

}];

Swift

let homeManager = TuyaSmartHomeManager()
homeManager.getHomeList(success: { homeList in
    homeList?.forEach({ homeModel in
        let home = TuyaSmartHome(homeId: homeModel.homeId)
        home?.getDetailWithSuccess({ _ in
            home?.deviceList.forEach({ deviceModel in
                if deviceModel.category == "sp" {
                    print(deviceModel.name!, "is a smart camera")
                }
            })
        }, failure: { error in

        })
    })
}) { error in

}

Note that the sample code here is only to show the simplest process of filtering out the camera device. In actual development, the device should be displayed and managed according to the logic of UI interaction.

1.3.2. Camera configuration information

After filtering out the smart camera devices, you can get the camera configuration information according to the device id, that is, the devId attribute ofTuyaSmartDeviceModel.

Configuration information needs to be obtained through Tuya open api.

Declaration

Parameters

You need to use the TuyaSmartRequest class to request the Tuya open api, refer to the document Common Interface.

1.3.3. Camera instance

The SDK provides factory methods for creating camera configuration objects and camera control objects.

Class and Protocol

According to the data returned by the interface, use the TuyaSmartCameraFactory to create aTuyaSmartCameraConfig object as a parameter for creating a camera object. TuyaSmartCameraFactory related interfaces are as follows:

Declaration

Create camera configuration object.

+ (TuyaSmartCameraConfig *)ipcConfigWithUid: (NSString *) uid localKey: (NSString *) localKey configData: (NSDictionary *) data;

Parameters

Return

Declaration

Create a camera instance object.

+ (id<TuyaSmartCameraType>)cameraWithP2PType:(id)type config:(TuyaSmartCameraConfig *)ipcConfig delegate:(id<TuyaSmartCameraDelegate>)delegate;

Parameters

Return

1.3.4. P2p type

The Tuya smart camera SDK supports three p2p channel implementation. The SDK initializes different camera specific implementation objects according to the p2p type.

ObjC

id p2pType = [deviceModel.skills objectForKey:@"p2pType"];

Swift

let p2pType = deviceModel.skills["p2pType"]

Example

ObjC

id p2pType = [deviceModel.skills objectForKey:@"p2pType"];
[[TuyaSmartRequest new] requestWithApiName:@"tuya.m.ipc.config.get" postData:@{@"devId": deviceModel.devId} version:@"2.0" success:^(id result) {
    TuyaSmartCameraConfig *config = [TuyaSmartCameraFactory ipcConfigWithUid:[TuyaSmartUser sharedInstance].uid localKey:deviceModel.localKey configData:result];
    id<TuyaSmartCameraType> camera = [TuyaSmartCameraFactory cameraWithP2PType:p2pType config:config delegate:self];
} failure:^(NSError *error) {

}];

Swift

let p2pType = deviceModel.skills["p2pType"]
TuyaSmartRequest().request(withApiName: "tuya.m.ipc.config.get", postData: ["devId" : deviceModel.devId], version: "2.0", success: { result in
    let config = TuyaSmartCameraFactory.ipcConfig(withUid: TuyaSmartUser.sharedInstance().uid, localKey: deviceModel.localKey, configData: result as? [AnyHashable : Any])
    let camera = TuyaSmartCameraFactory.camera(withP2PType: p2pType!, config: config!, delegate: self)
}) { error in

}

Note that in the above code, the self passed in the delegate parameter needs to implement the TuyaSmartCameraDelegate protocol.
