用於 MQTT 和 adafruit objc 的 iphone 應用程序無法正常工作

[英]iphone app for MQTT and adafruit objc not working

問題描述

我在 ESP8266-01 上構建了一個 MQTT 客戶端，它收集傳感器數據並將其發布到我在 Adafruit.com 上的帳戶儀表板。 我還在 ESP8266-12e 上構建了一個，它訂閱了我的 Adafruit 帳戶，並在其中一個儀表板值存在某些條件時打開一個 pin。 我正在嘗試使用此處的教程（ https://stablekernel.com/article/esp8266-programming-building-a-iot-weather-station-episode-3/#comments-area ）創建一個將訂閱的 iPhone 應用程序到 Adafruit 儀表板並顯示各種值，並在點擊按鈕時發布一個值。 我已經使用 Pods 安裝了框架並復制/修改了代碼，但是當我啟動應用程序時，它不會更新值，也不會在點擊按鈕時發布值。
這是我的 iPhone 應用程序代碼：

#import "ViewController.h"
#import <MQTTClient/MQTTClient.h>
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UILabel *batteryValueLabel;
@property (strong, nonatomic) IBOutlet UILabel *tempValueLabel;
@property (weak, nonatomic) IBOutlet UILabel *levelValueLabel;
@property (weak, nonatomic) IBOutlet UILabel *tripValueLabel;
@property (weak, nonatomic) IBOutlet UILabel *dateValueLabel;
@property(nonatomic, strong, readwrite) NSArray *certificates;
@property(nonatomic, weak) IBOutlet UIButton *Fill;


-(IBAction)Turnon:(id)sender;
@end
NSString *trip = @"0";
int trigger =1;
MQTTSession *session;
@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    MQTTCFSocketTransport *transport = [[MQTTCFSocketTransport alloc] init];
    transport.host = @"io.adafruit.com";
    transport.port = 1883;
    transport.certificates = [NSArray arrayWithObjects:@"xxxxxx",@"axxxxxxxxxxxxxxxxxxxx", nil];
    session = [[MQTTSession alloc] init];
    session.transport = transport;
    session.delegate = self;
    [session connectAndWaitTimeout:30];
    [session subscribeToTopic:@"feeds/date" atLevel:1 subscribeHandler:^(NSError *error, NSArray *gQoss){
//These never get called
        if (error) {
            NSLog(@"Subscription failed %@", error.localizedDescription);
        } else {
            NSLog(@"Subscription sucessfull! Granted Qos: %@", gQoss);
        }
    }];
}
- (void)newMessage:(MQTTSession *)session
              data:(NSData *)data
           onTopic:(NSString *)topic
               qos:(MQTTQosLevel)qos
          retained:(BOOL)retained
               mid:(unsigned int)mid {
    NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
//These don't get called
    NSLog(@"%@", topic);
    NSLog(@"%@", dataString);
    if ([topic isEqualToString:@"feeds/date"]){
        self.dateValueLabel.text = dataString;}
}
-(IBAction)Turnon:(id)sender;{
    if(trigger ==1){
        trip = @"0";
        trigger = 2;
    }
    else if(trigger==2){
        trip = @"100";
        trigger = 1;
    }
    NSData* data = [trip dataUsingEncoding:NSUTF8StringEncoding];
    [session publishData:data onTopic:@"feeds/trip" retain:NO qos:1 publishHandler:nil];
    NSLog(@"%@", trip);
    NSLog(@"%d",trigger);
}
@end

這是我打開應用程序並嘗試訂閱時的日志：

如果我發布了太多代碼，我很抱歉，但我希望每個人都能獲得他們需要的盡可能多的信息。 如果有人做過這樣的事情，請幫忙。

1 個解決方案

所以我通過添加連接：

session = [[MQTTSession alloc] init];
    session.userName = @"xxxxxxxxx";
    session.password = @"xxxxxxxxxxxxxxxxxxxxxxxxxxx";
    session.transport = transport;
    session.delegate = self;
    [session connectWithConnectHandler:^(NSError *error) {
        if(!error){
    [session subscribeToTopic:@"feeds/temperature" atLevel:1 subscribeHandler:^(NSError *error, NSArray *gQoss){
        if (error) {
            NSLog(@"Subscription failed %@", error.localizedDescription);
        } else {
            NSLog(@"Subscription sucessfull! Granted Qos: %@", gQoss);
        }
    }];
            }
        else {NSLog(@"[connectWithConnectHandler]Error Connect %@", error.localizedDescription);}
    }];

到我的代碼。

但是我沒有從 Adafruit 那里得到一個錯誤

MQTT 錯誤：被拒絕，不是有效的主題格式

有沒有其他人有這個問題。 我想我會發布另一個關於這個問題的問題。 我希望應該減少代碼。
