ios 開發 ping

在win 或 mac系統的終端下都有方便的ping命令來檢測網絡的連通性！

在iOS上可使用蘋果封裝好的工具來開發ping鏈接測試

SimplePing 下載

1. 主要接口

//初始化一個地址
- (instancetype)initWithHostName:(NSString *)hostName NS_DESIGNATED_INITIALIZER;

//開始ping
- (void)start;

//發送ping數據
- (void)sendPingWithData:(nullable NSData *)data;

//中止
- (void)stop;

2. 主要回調

@optional


//ping 開始
- (void)simplePing:(SimplePing *)pinger didStartWithAddress:(NSData *)address;


//ping 失敗
- (void)simplePing:(SimplePing *)pinger didFailWithError:(NSError *)error;

//成功發送一份ping數據
- (void)simplePing:(SimplePing *)pinger didSendPacket:(NSData *)packet sequenceNumber:(uint16_t)sequenceNumber;

//發送ping數據失敗
- (void)simplePing:(SimplePing *)pinger didFailToSendPacket:(NSData *)packet sequenceNumber:(uint16_t)sequenceNumber error:(NSError *)error;


//收到ping響應數據
- (void)simplePing:(SimplePing *)pinger didReceivePingResponsePacket:(NSData *)packet sequenceNumber:(uint16_t)sequenceNumber;


//收到未知響應數據
- (void)simplePing:(SimplePing *)pinger didReceiveUnexpectedPacket:(NSData *)packet;

3. 測試程序SimplePing app

    

4. 示例中還有一個測試用的mactool,編譯生成可執行文件，在終端下執行
