有安卓的同学会 iOS 的吗求帮忙把下面的代码翻译成 iOS 的版本

iOS 项目用的第三方 socket 库 GCDAsyncSocket

import java.net.DatagramPacket; import java.net.DatagramSocket; import java.net.InetAddess;

public class teststr { public static void main(String[] args) { wakeup(); } public static void wakeup(){ String mac = "00:30:64:69:F8:A7"; //mac 地址 // String mac = "00:02:a0:01:26:84"; try {

 int port = 9; byte[] macByte = new byte[6]; String[] ips = mac.split("\\:|\\-"); for (int i = 0; i < 6; i++) { macByte[i] = (byte) Integer.parseInt(ips[i], 16); } // 用来存储网络唤醒数据包 byte[] bys = new byte[6 + 16 * macByte.length]; for (int i = 0; i < 6; i++) { bys[i] = (byte) 0xff; } for (int i = 6; i < bys.length; i += macByte.length) { System.arraycopy(macByte, 0, bys, i, macByte.length); } // 将字符形式的 IP 地址转换成标准的 IP 地址 InetAddress address = InetAddress.getByName("192.168.100.255");

// InetAddress address = InetAddress.getByName("255.255.255.255"); // 生成标准的数据报 DatagramPacket pack = new DatagramPacket(bys, bys.length, address, port); // 创建标准套接字，用来发送数据报 DatagramSocket socket = new DatagramSocket(); // 发送魔法包 socket.send(pack); socket.close(); } catch (Exception e) { e.printStackTrace(); } catch (Throwable e) { e.printStackTrace(); } } }

用 GPT 啊

#import <Foundation/Foundation.h>
#import "GCDAsyncUdpSocket.h"

@interface TestStr : NSObject
+ (void)wakeup;
@end

@implementation TestStr

+ (void)wakeup {
NSString *mac = @"00:30:64:69:F8:A7"; // mac 地址

int port = 9;
NSArray *macCompOnents= [mac componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@":-"]];
NSMutableData *macData = [NSMutableData data];

for (NSString *component in macComponents) {
unsigned char byte;
[[NSScanner scannerWithString:component] scanHexInt:(unsigned int *)&byte];
[macData appendBytes:&byte length:1];
}

// 用来存储网络唤醒数据包
NSMutableData *wakeupData = [NSMutableData dataWithLength:6 + 16 * macData.length];
memset([wakeupData mutableBytes], 0xff, 6);

for (int i = 6; i < wakeupData.length; i += macData.length) {
[macData getBytes:[wakeupData mutableBytes] + i length:macData.length];
}

// 创建 UDP 套接字
GCDAsyncUdpSocket *udpSocket = [[GCDAsyncUdpSocket alloc] initWithDelegate:nil delegateQueue:dispatch_get_main_queue()];

// 将字符形式的 IP 地址转换成标准的 IP 地址
NSData *addressData = [@"192.168.100.255" dataUsingEncoding:NSUTF8StringEncoding];
// NSData *addressData = [@"255.255.255.255" dataUsingEncoding:NSUTF8StringEncoding];

// 发送魔法包
[udpSocket sendData:wakeupData toHost:[GCDAsyncUdpSocket hostFromAddress:addressData] port:port withTimeout:-1 tag:0];

[udpSocket close];
}

@end

int main(int argc, const char * argv[]) {
@autoreleasepool {
[TestStr wakeup];
}
return 0;
}

以下是将给定的 Java 代码转换为 iOS 使用 GCDAsyncSocket 库的 Swift 代码：
import Foundation
import CocoaAsyncSocket

func wakeup() {
let mac = "00:30:64:69:F8:A7"
// let mac = "00:02:a0:01:26:84"

let port: UInt16 = 9
let ips = mac.split(separator: ":").map { String($0) }
var macBytes = [UInt8]()

for ip in ips {
if let byte = UInt8(ip, radix: 16) {
macBytes.append(byte)
}
}

var bys = [UInt8](repeating: 0xff, count: 6 + 16 * macBytes.count)

for i in 6..<bys.count where i % macBytes.count == 0 {
bys.replaceSubrange(i..<i+macBytes.count, with: macBytes)
}

guard let address = InetAddress("192.168.100.255") else {
print("Invalid IP address")
return
}

let socket = GCDAsyncUdpSocket(delegate: nil, delegateQueue: DispatchQueue.main)

do {
let pack = GCDAsyncUdpSendPacket(data: Data(bys), address: address.host, port: port, timeout: -1)
try socket?.send(pack, withTimeout: -1)
} catch let error {
print("Error: \(error.localizedDescription)")
}

socket?.close()
}

// You can call wakeup() function from where you need to wake up the device.
请注意，此代码使用了 CocoaAsyncSocket 库，你需要确保在你的 iOS 项目中添加了该库。

这个是智谱的答案，跟 gpt 一样么？

iOS 项目使用的第三方 socket 库是`GCDAsyncSocket`。以下是您提供的 Java 代码的 iOS 版本，使用了`GCDAsyncSocket`库。请注意，您需要确保已经将`GCDAsyncSocket`库添加到您的 iOS 项目中。
```objective-c
#import <Foundation/Foundation.h>
#import <GCDAsyncSocket/GCDAsyncSocket.h>
@interface teststr : NSObject
@end
@implementation teststr
- (void)wakeup {
NSString *macAddress = @"00:30:64:69:F8:A7"; // mac 地址
// 省略了初始化代码...

int port = 9;
NSData *macData = [NSData dataWithBytes:macAddress.bytes length:macAddress.length];
NSMutableData *bys = [NSMutableData dataWithLength:6 + 16 * macData.length];
for (int i = 0; i < 6; i++) {
[bys setData:[NSData dataWithBytes:&0xff length:1] atIndex:i];
}
for (int i = 6; i < bys.length; i += macData.length) {
[bys insertData:macData atIndex:i];
}

// 将字符形式的 IP 地址转换成标准的 IP 地址
NSString *ipAddress = @"192.168.100.255";
NSData *addressData = [ipAddress dataUsingEncoding:NSUTF8StringEncoding];
NSData *address = [NSData dataWithBytes:addressData.bytes length:addressData.length];

GCDAsyncUdpSocket *socket = [[GCDAsyncUdpSocket alloc] initWithDelegate:self queue:dispatch_get_main_queue()];
[socket setDelegateQueue:dispatch_get_main_queue()];
[socket bindToAddress:address onPort:port error:nil];
[socket setReuseAddress:YES];
[socket setEnableBroadcast:YES];
[socket sendData:bys toHost:address onPort:port withTimeout:0 tag:0];
[socket close];
}
@end
```
在这个 iOS 版本中，我们使用了`GCDAsyncUdpSocket`来发送 UDP 数据报。请确保你的`GCDAsyncSocket`库已经正确集成到项目中，并且已经添加了所有必要的引用。此外，这段代码应该在主线程中运行，因为它涉及到 UI 操作。

```swift
import Foundation
import CocoaAsyncSocket

class WakeOnLan: NSObject, GCDAsyncUdpSocketDelegate {
var udpSocket: GCDAsyncUdpSocket!

override init() {
super.init()
udpSocket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
}

func wakeup(macStr: String, ipStr: String, port: UInt16) {
let macBytes = macStr.split(separator: ":").compactMap { UInt8($0, radix: 16) }
guard macBytes.count == 6 else { return }

var packet = Data(repeating: 0xFF, count: 6)
for _ in 0..<16 {
packet.append(contentsOf: macBytes)
}

do {
try udpSocket.enableBroadcast(true)
udpSocket.send(packet, toHost: ipStr, port: port, withTimeout: -1, tag: 0)
} catch {
print("发送数据包时出现了问题: \(error)")
}
}

// GCDAsyncUdpSocketDelegate methods
func udpSocket(_ sock: GCDAsyncUdpSocket, didSendDataWithTag tag: Int) {
print("数据包发送成功")
sock.close() // 发送完毕后关闭套接字
}

func udpSocket(_ sock: GCDAsyncUdpSocket, didNotSendDataWithTag tag: Int, dueToError error: Error?) {
if let error = error {
print("未能发送数据包, 错误: \(error)")
}
sock.close() // 如果发送失败，也关闭套接字
}

func udpSocketDidClose(_ sock: GCDAsyncUdpSocket, withError error: Error?) {
if let error = error {
print("UDP socket 已关闭, 错误: \(error)")
} else {
print("UDP socket 已正常关闭")
}
}
}

// 使用
let wol = WakeOnLan()
wol.wakeup(macStr: "00:30:64:69:F8:A7", ipStr: "192.168.100.255", port: 9)
```

看楼上代码感觉问题不大记得 podfile 里添加完库后记得 pod update 或者 install 不然拉不到库代码
