任何人都可以看到为什么世界上没有调用SelectRowAtIndexPath会被调用？我delegate在代码和故事板中都进行了三重检查.
class AddCard: UIViewController,UIPopoverPresentationControllerDelegate, UITableViewDataSource, UITableViewDelegate {
@IBOutlet weak var cardView: UIView!
@IBOutlet weak var tableView: UITableView!
let tableItems = ["Background Color","Background Image","Font Style","Font Color"]
let cellID = "cell"
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func setBackgroundColor (_ color: UIColor) {
cardView.backgroundColor = color
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: …我想连接 ble 外设。但我的代码没有调用 didConect 函数
这是我的代码：
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
let device = (advertisementData as NSDictionary)
.object(forKey: CBAdvertisementDataLocalNameKey)
as? NSString
if device?.contains(BEAN_NAME) == true {
print("Did discover peripheral", peripheral)
self.bluetoothManager.stopScan()
self._peripheral = peripheral
self._peripheral.delegate = self
central.connect(peripheral, options: nil)
}
}
func centralManager( central: CBCentralManager, didConnect peripheral: CBPeripheral) { //cant call this
print("connected to \(BEAN_NAME)")
peripheral.discoverServices(nil)
}
日志：
BLE service is powered on
Did discover peripheral <CBPeripheral: 0x1740eef00, identifier …
