ios - Swift - MultipeerConnectivity 类型不符合协议(protocol)

Question

我正在尝试 this tutorial代码有问题:

class MPCManager: NSObject, MCSessionDelegate, MCNearbyServiceBrowserDelegate, MCNearbyServiceAdvertiserDelegate {

我遇到了一个错误:

Type 'MPCManager' does not comform to protocol 'MCSessionDelegate'

Type 'MPCManager' does not comform to protocol 'MCNearbyServiceBrowserDelegate'

Type 'MPCManager' does not comform to protocol 'MCNearbyServiceAdvertiserDelegate'

但是我下载了示例文件却没有出现同样的错误。我错过了哪一部分？

Answer 1

如果你想遵守这些协议(protocol)，你需要实现 MCSessionDelegate 和 MCNearbyServiceBrowserDelegate 和 MCNearbyServiceAdvertiserDelegate 所有必需的委托(delegate)方法。
