找出用户要求绑定 BLe 设备的决定 (Objective-C, iOS 10)

Question

是否可以让 iOS 的绑定请求的用户决定？

选择 1：放弃
选择 2：Connect/Bond

绑定请求截图：

我尝试使用 centralManagerDidUpdateState，但如果我打开蓝牙，它只会用 CBManagerStatePoweredOn 调用一次。

#pragma mark - CBCentralManagerDelegate
- (void)centralManagerDidUpdateState:(CBCentralManager *)central {

    info(@"centralManagerDidUpdateState");

        switch(central.state){

            case CBManagerStateUnauthorized:
                info(@"unauthorized");
                break;

            case CBManagerStatePoweredOff:
                info(@"poweredOff");
                break;

            case CBManagerStatePoweredOn:
                info(@"poweredOn");
                break;

            case CBManagerStateResetting:
                info(@"resetting");
                break;

            case CBManagerStateUnknown:
                info(@"unknown");
                break;

            case CBManagerStateUnsupported:
                info(@"unsupported");
                break;
        }
}

我也试过用"didConnectPeripheral"和"didFailToConnectPeripheral":

- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral {
    [peripheral setDelegate:self];
    [self _cancelConnectionRequests];
    [peripheral discoverServices:nil];

    BleDevice* bleDevice = [knownDevices findDevice:[peripheral.identifier UUIDString]];
    devicePaired(bleDevice.deviceId, bleDevice.primaryServiceUuid);
}

- (void)centralManager:(CBCentralManager *)central didFailToConnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error {
    [peripheral setDelegate:self];
    [self _cancelConnectionRequests];
    [peripheral discoverServices:nil];

    BleDevice* bleDevice = [knownDevices findDevice:[peripheral.identifier UUIDString]];
    deviceNotPaired(bleDevice.deviceId, bleDevice.primaryServiceUuid);
}

但是点击"Abort"或"Connect/Bond"后两种方法都没有被调用！在尝试连接到设备时至少只调用 "didConnectPeripheral" - 但这是在弹出窗口出现之前发生的！

还有其他想法吗？

Note: I have no problems with scanning, connecting or bonding with a BLe device - I only want to know if the user accepted the bonding-request from his iPhone!

Answer 1

不，这不可能。我不知道苹果为什么做出这个决定，因为从安全的角度来看，应用程序知道 link 是否已正确加密和验证可能很重要。

如果你可以控制外围设备的固件，你可以让它在配对事件发生时发送一些特性。
