Ios 我可以设置 WKWebView 使用的 cookie 吗

Edit for iOS 11+ only

使用WKHTTPCookieStore:

let cookie = HTTPCookie(properties: [
    .domain: "example.com",
    .path: "/",
    .name: "MyCookieName",
    .value: "MyCookieValue",
    .secure: "TRUE",
    .expires: NSDate(timeIntervalSinceNow: 31556926)
])! 

webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)

由于您要将它们从HTTPCookeStorage拉过来，因此可以执行以下操作:

let cookies = HTTPCookieStorage.shared.cookies ?? []
for cookie in cookies {
    webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)
}

Old answer for iOS 10 and below

如果您需要在初始加载请求上设置cookie，可以在NSMutableURLRequest上设置它们.因为Cookie只是一个特殊格式化的请求头，所以可以这样实现:

WKWebView * webView = /*set up your webView*/
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/index.html"]];
[request addValue:@"TeskCookieKey1=TeskCookieValue1;TeskCookieKey2=TeskCookieValue2;" forHTTPHeaderField:@"Cookie"];
// use stringWithFormat: in the above line to inject your values programmatically
[webView loadRequest:request];

如果需要页面上的后续AJAX请求设置cookie，只需在文档开始时使用WKUserScript通过javascript编程设置值即可实现，如下所示:

WKUserContentController* userContentController = WKUserContentController.new;
WKUserScript * cookieScript = [[WKUserScript alloc] 
    initWithSource: @"document.cookie = 'TeskCookieKey1=TeskCookieValue1';document.cookie = 'TeskCookieKey2=TeskCookieValue2';"
    injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
// again, use stringWithFormat: in the above line to inject your values programmatically
[userContentController addUserScript:cookieScript];
WKWebViewConfiguration* webViewConfig = WKWebViewConfiguration.new;
webViewConfig.userContentController = userContentController;
WKWebView * webView = [[WKWebView alloc] initWithFrame:CGRectMake(/*set your values*/) configuration:webViewConfig];

将这两种技术结合起来，应该可以为您提供足够的工具，将cookie值从本机应用程序区转移到Web视图区.如果你需要更高级的cookie，你可以在cookie javascript API on Mozilla's page上找到更多信息.

是的，苹果不支持the niceties of UIWebView个中的很多个，这真是太糟糕了.我不确定他们是否会支持他们，但希望他们很快就能做到这一点.希望这能有所帮助！
