Question

我需要捕捉动态单元格中的开关的修改。该应用程序具有动态单元格，可列出找到的所有BLE设备。

BLE设备应该能够通过开关打开/关闭。

现在是问题，我无法通过Outlet或Action捕获开关。

如何从动态单元格中捕获更改。

问题的UI看起来像这样： UI with dynamic cell

我找到了可以抓住水龙头的地方，但在那里我无法使用我的方法，因为在类类型UITableViewCell CoreBluetooth不受支持，我无法填写CoreBluetooth方法的属性。

import UIKit


class remoteCellTableViewCell: UITableViewCell{

    //MARK: Properties
    @IBOutlet weak var remoteCellLabel: UILabel!
    @IBOutlet weak var remoteCellImageView: UIImageView!
    @IBOutlet weak var remoteCellSwitch: UISwitch!
    @IBOutlet weak var remoteCellPower: UIProgressView!

    override func awakeFromNib() {
        super.awakeFromNib()

    }

    //HERE I CAN CATCH THE SWITCH TAP BUT I CAN'T USE CoreBluetooh IN THIS CLASS
    @IBAction func onOff(sender: AnyObject) {


        //OBJECT FROM THE CLASS FOR CONNECT AND SEND TO THE PERIPHERAL
        var connection: ViewController = ViewController()

        connection.viewDidLoad()


        //CANT FILLOUT THE ATTRIBUTES BECAUSE OF MISSING COREBLUETOOTH SUPPORT
    //-->        
        connection.centralManagerDidUpdateState(<#T##central: CBCentralManager##CBCentralManager#>)
        connection.centralManager(<#T##central: CBCentralManager##CBCentralManager#>, didDiscoverPeripheral: <#T##CBPeripheral#>, advertisementData: <#T##[String : AnyObject]#>, RSSI: <#T##NSNumber#>)
        connection.centralManager(<#T##central: CBCentralManager##CBCentralManager#>, didConnectPeripheral: <#T##CBPeripheral#>)
        connection.centralManager(<#T##central: CBCentralManager##CBCentralManager#>, didDiscoverPeripheral: <#T##CBPeripheral#>, advertisementData: <#T##[String : AnyObject]#>, RSSI: <#T##NSNumber#>)
        connection.centralManager(<#T##central: CBCentralManager##CBCentralManager#>, didConnectPeripheral: <#T##CBPeripheral#>)
        connection.peripheral(<#T##peripheral: CBPeripheral##CBPeripheral#>, didDiscoverServices: <#T##NSError?#>)
        connection.peripheral(<#T##peripheral: CBPeripheral##CBPeripheral#>, didDiscoverCharacteristicsForService: <#T##CBService#>, error: <#T##NSError?#>)
        connection.peripheral(<#T##peripheral: CBPeripheral##CBPeripheral#>, didUpdateValueForCharacteristic: <#T##CBCharacteristic#>, error: <#T##NSError?#>)
        connection.peripheral(<#T##peripheral: CBPeripheral##CBPeripheral#>, didWriteValueForDescriptor: <#T##CBDescriptor#>, error: <#T##NSError?#>)

    //->
    }
    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

    }

使用标签获取开关状态。这是我用于获取按钮单击操作的代码。喜欢这个

在 cellForRowAtIndexPath 中为该按钮指定标记。

cell.absentButton.tag = indexPath.row

在按钮操作中获取按钮行

if let button = sender as? UIButton {
  if button.selected {
    // set selected
    let row = sender.tag
 }
}

通过此，您可以获得更改的开关。
