iOS network diagnostics sdk

Introduction

By ingegrating iOS network diagnostics sdk you can easily do ping/traceroute/mobile public network information/port scanning on IPhone.

Take a screenshot of the network diagnostic app developed with this sdk:

• Download UNetState in App Store
• Welcome star & fork

Environment

• iOS >= 9.0
• Xcode >= 7.0
• Setting Enable Bitcode to NO

Installation and use

Pod dependency

Add the following dependencies to your project's Podfile:

pod 'PhoneNetSDK'

Quick start

Import the SDK header file to the project:

#import <PhoneNetSDK/PhoneNetSDK.h>

In addition, you need to add -lc++,-ObjC,$(inherited) to the project's Build Setting->other link flags. As shown below:

ping

 [[PhoneNetManager shareInstance] netStartPing:@"www.baidu.com" packetCount:10 pingResultHandler:^(NSString * _Nullable pingres) {
       // your processing logic 
  }];

TCP ping

_tcpPing = [PNTcpPing start:hostDomain port:portNum.integerValue count:3 complete:^(NSMutableString *pingres) {
	// your processing logic
}];

UDP traceroute

The default traceroute command on the command line sends a UDP packet (referred to as udp traceroute):

 _udpTraceroute = [PNUdpTraceroute start:ip complete:^(NSMutableString *res) {
                    // your processinig logic
                }];

ICMP traceroute

In the terminal of mac, enter traceroute -I baidu.com to use the ICMP protocol to do traceroute. This function is provided in sdk:

 [[PhoneNetManager shareInstance] netStartTraceroute:@"www.baidu.com" tracerouteResultHandler:^(NSString * _Nullable tracertRes, NSString * _Nullable destIp) {
     // your processing logic                
  }];

nslookup

[[PhoneNetManager shareInstance] netLookupDomain:@"www.google.com" completeHandler:^(NSMutableArray<DomainLookUpRes *> * _Nullable lookupRes, PNError * _Nullable sdkError) {
	// your processing logic
}];

port scan

[[PhoneNetManager shareInstance] netPortScan:@"www.baidu.com" beginPort:8000 endPort:9000 completeHandler:^(NSString * _Nullable port, BOOL isOpen, PNError * _Nullable sdkError) {
	// your processing logic    
}];

LAN Scanning

If you want to do the LAN active ip scanning function, then you can quickly monitor every active ip with the SDK, and the SDK will return to you the scanning progress.

Specific steps are as follows:

1. Create an object and set the proxy PNetMLanScannerDelegate
2. Start the scan and process the active ip through its delegate method
3. Monitor scan progress (optional)

 PNetMLanScanner *lanScanner = [PNetMLanScanner shareInstance];
 lanScanner.delegate =  self;
 [lanScanner scan];

Ohter functions

• Setting SDK log level
• Get device public ip info

NetPinger-Example

Ios platform network diagnostic APP (using the SDK), support ping and domain name ping, traceroute (udp, icmp protocol), support tcp ping, port scan, nslookup and other functions.

Simply go to the directory where the Podfile file is located and install the SDK to run successfully.

macdeiMac:NetPinger ethan$ pod install

Project origin

In development, you often encounter problems with the interface (DNS resolution error, etc.), so you need to detect whether the mobile terminal to the server's network is not connected, so you need to interrupt ping on the mobile phone, but the free network detection tool on the market. Most have pop-up ads affecting the experience (eg: iNetTools), so it is necessary to develop a web drama detection app.

Implementation

All functions are implemented using the functions provided by the SDK. The pages and icons are mainly imitating the NetWork Utility on the MAC, and hope to provide a valuable reference for your application.
