If there is a special limit, we need to visit a specific URL first and deposit a cookie

Nsurl * Cookiehost = [Nsurl urlwithstring:@"http://mmmmmm/login/Login.jsp"]; Nshttpcookie* Cookie =[Nshttpcookie cookiewithproperties: [nsdictionary Dictionarywithobjectsandkeys: [Cookiehost Host],nshttpcookiedomain, [Cookiehost Path],nshttpcookiepa Th,@"Cookie_name", Nshttpcookiename,@"Cookie_value", Nshttpcookievalue,nil]]; [[Nshttpcookiestorage Sharedhttpcookiestorage] setcookie:cookie];

Exit login in order to, without other interference, to clear the cookie

Nshttpcookiestorage * MyCookie = [Nshttpcookiestorage sharedhttpcookiestorage];      for inch [MyCookie cookies])    {[        [nshttpcookiestorage sharedhttpcookiestorage] deletecookie:cookie];    }             * Path = nshomedirectory ();     * FilePath = [path stringbyappendingpathcomponent:@ "/library/cookies/cookies.binarycookies " ];     * Manager = [Nsfilemanager Defaultmanager];    [Manager Removeitematpath:filepath Error:nil];

Initiate a request, with a cookie to request, disguised as a specific user-agent,referer, etc.

Nsurl * url = [Nsurl urlwithstring:@"http://mmmmm/login/Login.jsp"]; Nsmutableurlrequest* Request =[Nsmutableurlrequest Requestwithurl:url]; Nsarray* Cookies =[[Nshttpcookiestorage sharedhttpcookiestorage] cookies]; Nsdictionary* headers =[Nshttpcookie requestheaderfieldswithcookies:cookies]; [Request SetValue:@"mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) applewebkit/537.36 (khtml, like Gecko) chrome/54.0.2840.98 safari/537.36"Forhttpheaderfield:@"user-agent"]; [Request SetValue:@"http://mmmmmm"Forhttpheaderfield:@"Origin"]; [Request SetValue:@"http://mmmmm/login/Login.jsp"Forhttpheaderfield:@"Referer"]; [Request Sethttpmethod:@"GET"];    [Request Sethttpshouldhandlecookies:yes]; [Request Setallhttpheaderfields:headers];

If you want to access the URL in a specific network environment, you have to deal with the judgment, of course, in this case, only limited

NSString *ipstring = [self deviceipadress][@ "en1/ipv4"];     = ipstring? Ipstring: [Self deviceipadress][@ "en0/ipv4"];         if ([self canloadnetfrom:ipstring]) {        [Self.webview loadrequest:request];     Else {        [svprogresshud showerrorwithstatus:@ " Current network environment does not support login "];    }

Update: To switch between different account passwords, how to re-write the program? Here with Settings.bundle.

And just pick it up with your preference.

Nsuserdefaults *user = [Nsuserdefaults standarduserdefaults];     *accout = [user stringforkey:@ "name_preference"];     *PSD = [user stringforkey:@ "psd_preference"];
