【问题描述】：

我正在开发一个使用 CoreBluetooth 框架的应用程序 ios 应用程序，我正在尝试从“didDiscoverPheripheral”方法的 CBPeripheral 对象中获取手机的名称并将其添加到数组中，以便可以在 tableView 上显示它。我的意思是“电话名称”类似于“Dan 的 iPhone”。 稍后我想按下 tableView 上的行，以便连接到该设备。

我试过了：

 - (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral    *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI 

NSLog(@"Discovered %@ at %@", peripheral.name, RSSI);

if (_discoveredPeripheral != peripheral) 
    // Save a local copy of the peripheral, so CoreBluetooth doesn't get rid of it
    _discoveredPeripheral = peripheral;

    // And connect
    NSLog(@"Connecting to peripheral %@", peripheral);
   // here i want to add the name of the device to an array

有什么想法吗？？

【问题讨论】：

NSLog(@"设备名称: %@", [[UIDevice currentDevice] name]);

运行这段代码会发生什么？

【参考方案1】：

你为什么不在你发现之后添加外围设备，而不是在你的蓝牙类中创建另一个方法并调用它来从 TableView 连接到选定的设备：

 - (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral    *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI 

     NSLog(@"Discovered %@ at %@", peripheral.name, RSSI);
      // add found devices to class variable NSMutableArray<CBPeripheral> *foundPeripherals
     // do not forget to initialize it
     [self.foundPeripherals addObject:peripheral];



// create a connect method where you pass the device selected identifier
- (void) connect:(NSString*)uuidString 
    CBPeripheral* peripheral;
    for (peripheral in self.foundPeripherals)
        if(peripheral.state == CBPeripheralStateDisconnected)
            // this will invoke didConnectPeripheral once connection 
            // set successfully
            [self connectPeripheral:peripheral];
        
    


// store the connected peripheral
- (void) centralManager:(CBCentralManager *)central didConnectPeripheral:     (CBPeripheral *)peripheral

    NSLog(@"Attempted connection to peripheral %@ succeed.", [peripheral name]);
    // store the connected device info in class property
    self.peripheral = peripheral;
