问题描述
我正在使用CBPeripheralManager在iPhone和设备之间建立BLE连接.
I'm making BLE connection between iPhone and device with CBPeripheralManager.
如果Central尝试与外围设备配对，则会弹出蓝牙配对alertController，用户可以选择要使用的蓝牙配对.他们中的大多数人都会按下连接按钮.
If Central tried to pair with peripheral, Bluetooth pairing alertController pops up and user can choice which one there're going to use. Most of them will push a connect button.
但是有什么方法可以知道用户何时按下取消按钮吗?
But is there a way to know when user push a cancel button?
Delegate API会很好，但我找不到它.
Delegate API would be good but I couldn't find it.
推荐答案
我不确定，但是 didFailToConnectPeripheral 方法是处理您的案件的好地方.
I'm not sure, but maybe didFailToConnectPeripheral method of CBCentralManagerDelegate is a good place to handle your case.
这篇关于在CBPeripheralManager中，如何知道用户在尝试配对时是否按下了“取消"按钮的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
