ios怎么读取cookie

在 iOS 中读取 Cookie 的步骤如下:

1. 导入 `WebKit` 框架:

```swift

import WebKit

```

2. 获取 `WKWebView` 实例:

```swift

let webView = WKWebView()

```

3. 使用 `HTTPCookieStorage` 类从默认的 cookie 存储中获取 cookies:

```swift

let cookies = HTTPCookieStorage.shared.cookies(for: URL(string: "https://example.com")!)

```

4. 遍历 cookies 数组,获取需要的 cookie 信息:

```swift

for cookie in cookies ?? [] {

print("Name: \(cookie.name), Value: \(cookie.value)")

}

```

如果你需要在 WebView 加载完成后读取 cookie,可以使用 `WKNavigationDelegate` 协议的 `webView(_:didFinish:)` 方法:

```swift

class ViewController: UIViewController, WKNavigationDelegate {

let webView = WKWebView()

override func viewDidLoad() {

super.viewDidLoad()

webView.navigationDelegate = self

webView.load(URLRequest(url: URL(string: "https://example.com")!))

}

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {

let cookies = HTTPCookieStorage.shared.cookies(for: webView.url!)

for cookie in cookies ?? [] {

print("Name: \(cookie.name), Value: \(cookie.value)")

}

}

}

```

这样就可以在 WebView 加载完成后读取并处理 cookie 信息了。
