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

Question

是否可以让用户决定iOS的绑定(bind)请求？

• 选择 1:放弃
• 选择 2:连接/绑定(bind)

绑定(bind)请求截图:

我尝试使用 centralManagerDidUpdateState，但如果我打开蓝牙，它只会通过 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;
        }
}

我还尝试使用“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);
}

但是在点击“Abort”或“Connect/Bond”后，这两种方法都不会被调用!在尝试连接到设备时至少只调用“didConnectPeripheral”——但这发生在弹出窗口出现之前!

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 Apple 为何做出此决定，因为从安全角度来看，应用程序了解链接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关于特征的东西。
