删除NSURLSession iOS中的所有cookie

Question

我如何从NSHTTPCookieStorage.sharedHTTPCookieStorage中删除所有的cookie？我知道的唯一方法是删除单个指定的cookie，但是cookie是由NSURLSession幕后处理的。(利用Swift编程)

Answer 1

let cookieStore = NSHTTPCookieStorage.sharedHTTPCookieStorage()
for cookie in cookieStore.cookies ?? [] {
    cookieStore.deleteCookie(cookie)
}

Answer 2

这获得了与其他答案相同的结果，但使用了一行代码：

HTTPCookieStorage.shared.cookies?.forEach(HTTPCookieStorage.shared.deleteCookie)

Answer 3

同样，对于3.0+，xCode 8.0+

let cookieStore = HTTPCookieStorage.shared
for cookie in cookieStore.cookies ?? [] {
    cookieStore.deleteCookie(cookie)
}
