再会WKWebView

有关WKWebView处理cookie问题，又多次测试，发现并不需要在 初识WKWebView那么麻烦，有更简便的方法，实例代码如下：

WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
    WKUserContentController* userContentController = WKUserContentController.new;
    WKUserScript * cookieScript = [[WKUserScript alloc]
                                   initWithSource:[self obainSettingCookieJs]
                                   injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
    [userContentController addUserScript:cookieScript];
   userContentController;

- (NSString *)obainSettingCookieJs{
    NSString *JSFuncString =
    @"function setCookie(name,value,expires)\
    {\
    var oDate=new Date();\
    oDate.setTime(oDate.getTime()+(expires*24*3600*1000));\
    document.cookie=name+'='+value+';expires='+oDate+';path=/';\
    }\
    function getCookie(name)\
    {\
    var arr = document.cookie.match(new RegExp('(^| )'+name+'=([^;]*)(;|$)'));\
    if(arr != null) {return unescape(arr[2]); } else { return null;}\
    }\
    function delCookie(name)\
    {\
    var exp = new Date();\
    exp.setTime(exp.getTime() - 1);\
    var cval=getCookie(name);\
    if(cval!=null) document.cookie= name + '='+cval+';expires='+exp.toGMTString();\
    }";
    
    //拼凑js字符串
    //取出 JSESSIONID  uid token
    //    [SettingBaseTool deleteDatasByKey:jessionString];
    //     [SettingBaseTool deleteDatasByKey:uidString];
    //     [SettingBaseTool deleteDatasByKey:tokenString];
    NSMutableString *JSCookieString = JSFuncString.mutableCopy;
    //把cookie所有值传过去
    NSMutableArray *allCookiesArray = [SettingBaseTool queryAllCookies];
    for (NSString *cookiesString in allCookiesArray) {
        NSArray *cookiesArray = [cookiesString componentsSeparatedByString:kCookieConnectString];
        if ([cookiesArray isNotEmpty]&&(cookiesArray.count == 2)) {
            NSString *keyString = cookiesArray[0];
            NSString *valueString = cookiesArray[1];
            if ([valueString isNotEmpty]) {
                NSString *excuteJSString = [NSString stringWithFormat:@"setCookie('%@', '%@', 15);", keyString, valueString];
                [JSCookieString appendString:excuteJSString];
            }
        }
        
        
        
    }
    return JSCookieString;
}

注意点：
1，通过WKUserScript
2，设置cookie格式
