UIWebView實作自動登陸（存儲、讀取Cookie）

1.在AppDelegate中鍵入這幾句代碼

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    NSURL *cookieHost = [NSURLURLWithString:@"http://appweb.cosfund.com"];
    NSDictionary *propertiesDict = [NSDictionarydictionaryWithObjectsAndKeys:[cookieHosthost],NSHTTPCookieDomain,[cookieHostpath],NSHTTPCookiePath,@"COOKIE_NAME",NSHTTPCookieName,@"COOKIE_VALUE",NSHTTPCookieValue,nil];
    NSHTTPCookie *cookie = [NSHTTPCookiecookieWithProperties:propertiesDict];
    [[NSHTTPCookieStoragesharedHTTPCookieStorage] setCookie:cookie];

    return YES;
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    
    [[NSHTTPCookieStoragesharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];
}
           

2.UIWebView加載的适合設定HTTPHeader

- (void)uiConfig
{
    NSURL *url = [NSURLURLWithString:@"http://appweb.cosfund.com/lcrank/index2.html?phone=15601667246"];
    NSMutableURLRequest *request = [NSMutableURLRequestrequestWithURL:url];
    NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    NSDictionary *headers = [NSHTTPCookierequestHeaderFieldsWithCookies:cookies];
    [request setHTTPMethod:@"POST"];
    [request setHTTPShouldHandleCookies:YES];
    [request setAllHTTPHeaderFields:headers];
    [self.webViewloadRequest:request];
}
           

3.退出登陸時删除Cookie

- (void)LoggedOutBtnClick:(UIButton *)button
{
    //清空Cookie
    NSHTTPCookieStorage *myCookie = [NSHTTPCookieStoragesharedHTTPCookieStorage];
    for (NSHTTPCookie *cookiein [myCookie cookies])
    {
        [[NSHTTPCookieStoragesharedHTTPCookieStorage] deleteCookie:cookie];
    }
    //删除沙盒自動生成的Cookies.binarycookies檔案
    NSString *path = NSHomeDirectory();
    NSString *filePath = [pathstringByAppendingPathComponent:@"/Library/Cookies/Cookies.binarycookies"];
    NSFileManager *manager = [NSFileManagerdefaultManager];
    [manager removeItemAtPath:filePath error:nil];
}
