IoT Platform：Verifikasi dan sambungkan perangkat

Inisialisasi IoT Platform SDK untuk Java

Contoh kode:

#import <IotLinkKit/IotLinkKit.h>

    // Sebelum Anda menginisialisasi SDK, Anda harus membuat pendengar untuk memantau perubahan status koneksi persisten.
    [[LinkKitEntry sharedKit] registerChannelListener:self];

    //// Tentukan informasi sertifikat perangkat.
    self.productKey = self.textFieldProductKey.text ;
    self.deviceName = self.textFieldDeviceName.text ;
    self.deviceSecret = self.textFieldDeviceSecret.text;

    LinkkitChannelConfig * channelConfig = [[LinkkitChannelConfig alloc] init];
    channelConfig.productKey = self.productKey;
    channelConfig.deviceName = self.deviceName;
    channelConfig.deviceSecret = self.deviceSecret;
    channelConfig.cleanSession = (self.cleanSession == 1);
    //channelConfig.server = @"your custom server url";
    //channelConfig.port = 1883;
    LinkkitSetupParams * setupParams = [[LinkkitSetupParams alloc] init];
    setupParams.appVersion = self.appVersion;
    setupParams.channelConfig = channelConfig;
    [[LinkKitEntry sharedKit] setup:setupParams resultBlock:^(BOOL succeeded, NSError * _Nullable error) {
        LinkkitLogDebug(@"setup error : %@", error);
        dispatch_async(dispatch_get_main_queue(), ^{
            [self ims_showHUDWithMessage:[NSString stringWithFormat:@ "Inisialisasi :%@",
                                          succeeded ? @ "Berhasil" : @ "Gagal"]];
        });
    }];
            

Parameter

Deinisialisasi SDK

Sebelum men-deinisialisasi SDK, tutup koneksi MQTT persisten antara perangkat dan IoT Platform. Untuk men-deinisialisasi SDK, panggil operasi API berikut.

    [[LinkKitEntry sharedKit] destroy:^(BOOL succeeded, NSError * _Nullable error) {
        LinkkitLogDebug(@"kit destroy error : %@", error);
        dispatch_async(dispatch_get_main_queue(), ^{
            [self ims_showHUDWithMessage:[NSString stringWithFormat:@ "Deinisialisasi: %@",
                                          succeeded ? @ "Berhasil" : @ "Gagal"]];
        });
    }];
            

Saklar log

Aktifkan saklar keluaran log internal SDK:

#import <IMSLog/IMSLog.h>

NSString * const IMS_DEMO_TAG = @"LinkkitDemo";

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Tambahkan kode berikut untuk mengaktifkan fitur logging.
    [IMSLog setAllTagsLevel:IMSLogLevelAll];
    // Buat panel log dan tambahkan ke kerangka log.
    //[IMSLog addAssistant:[[IMSDashboardLogAssistant alloc] init]];
    // Aktifkan log agar ditampilkan di konsol.
    [IMSLog showInConsole:YES];
    // Tentukan tag log.
    [IMSLog registerTag:IMS_DEMO_TAG];

    return YES;
}
            

Buat pendengar untuk memantau perubahan status koneksi MQTT persisten.

Contoh kode:

- (void)onConnectStateChange:(nonnull NSString *)connectId state:(LinkkitChannelConnectState)state {
    NSString * connectTip = nil;
    if (state == LinkkitChannelStateConnected) {
        connectTip = @ "Terkoneksi";
    } else if (state == LinkkitChannelStateDisconnected) {
        connectTip = @ "Tidak terkoneksi";
    } else {
        connectTip = @ "Menghubungkan";
    }
    dispatch_async(dispatch_get_main_queue(), ^{
        self.labelConnectState.text = connectTip;
    });
}

- (void)onNotify:(nonnull NSString *)connectId topic:(nonnull NSString *)topic data:(id _Nullable)data {
    NSString * downData = [NSString stringWithFormat:@ "Data yang didorong diterima, topik :%@ \r\n", topic];
    downData = [downData stringByAppendingString:[NSString stringWithFormat:@ "\r \ndata :%@", data]];

    LinkkitLogDebug(@"kit recv  topik : %@", topic);

    dispatch_async(dispatch_get_main_queue(), ^{
        self.textViewDownData.text = downData;
    });
}

- (BOOL)shouldHandle:(nonnull NSString *)connectId 
               topic:(nonnull NSString *)topic {
    return YES;
}
