app中加入h5，app端登錄，跳轉(zhuǎn)H5的時(shí)候?qū)⒌卿浶畔鹘oh5，這里的登錄信息可以是token值，或者用戶id看h5的需求，這里傳遞token值給h5

1、在傳遞token值之前首先需要清理一下cookie

 NSURL *url = [NSURL URLWithString:self.urlString];
    
    if (url) {//清除所有cookie
        NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:url];
        for (int i = 0; i < [cookies count]; i++) {
            NSHTTPCookie *cookie = (NSHTTPCookie *)[cookies objectAtIndex:i];
            [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
        }
    }
    

2、在加載html的時(shí)候?qū)oken通過cookie傳過去

 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
 NSMutableDictionary *properties = [NSMutableDictionary dictionary];
    [properties setValue:@"c24ae8jzfhgafghjkzfhjk00" forKey:NSHTTPCookieValue];
    [properties setValue:@"login_token" forKey:NSHTTPCookieName];
    [properties setValue:url.host forKey:NSHTTPCookieDomain];
    [properties setValue:@"/" forKey:NSHTTPCookiePath];
    NSHTTPCookie *cookie1 = [[NSHTTPCookie alloc] initWithProperties:properties];
    [properties setValue:@"fhlasjhdljkas" forKey:NSHTTPCookieValue];
    [properties setValue:@"JSESSIONID" forKey:NSHTTPCookieName];
    NSHTTPCookie *cookie2 = [[NSHTTPCookie alloc] initWithProperties:properties];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie1];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie2];
    [webVie loadRequest:request];

3、很多html不僅僅需要適配iOS ，這時(shí)候就需要傳遞一個(gè)標(biāo)示，讓html判斷后進(jìn)行適配，這里可以設(shè)置userAgent

 // 設(shè)置userAgent
    NSString *customUserAgent = @"ios_jfmore_1.0.0";
    [[NSUserDefaults standardUserDefaults] registerDefaults:@{@"UserAgent":customUserAgent}];
    NSMutableURLRequest *request = [NSMutableURLR

然后H5可以拿到的信息如下

4、這樣h5就可以拿到登錄態(tài)，進(jìn)行登錄同步，當(dāng)然如果沒有登錄的時(shí)候點(diǎn)擊了h5，可以讓h5給一個(gè)事件，這里采用攔截H5的方式吊起原生登錄，登錄完成跳轉(zhuǎn)h5，如下

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
    
        NSURL *url = [request URL];
        CLog(@"-----%@",url);
        if ([[url scheme] isEqualToString:@"native"]) {
            CLog(@"[url scheme] %@",[url scheme]);
            if ([[url host] isEqualToString:@"user"]) {
                CLog(@"[url host] %@",[url host]);
                // 登錄操作
                NSDictionary *params = [self getParams:[url query]];
                CLog(@"[url query] %@",[url query]);
                [self login:params];
                return NO;
            }
                if ([[url host] isEqualToString:@"device"]) { // 返回原生界面
                    [self Pop];
                    return NO;
                }
        }
        return YES;
}

// 將請(qǐng)求體的內(nèi)容轉(zhuǎn)換為字段
- (NSDictionary *)getParams:(NSString *)query {
    NSArray *paramArray = [query componentsSeparatedByString:@"&"];
    NSMutableDictionary *paramDic = [[NSMutableDictionary alloc] init];
    for (NSString *aParam in paramArray) {
        NSArray *keyValues = [aParam componentsSeparatedByString:@"="];
        [paramDic setObject:keyValues[1] forKey:keyValues[0]];
    }
    CLog(@"----%@",paramDic);
    return paramDic;
}
- (void)login:(NSDictionary *)dict
{
// 吊起原生登錄
    JFUserLoginViewController *userLogin = [[JFUserLoginViewController alloc]init];
    [self presentToVc:userLogin];
    
// 登錄成功后將用戶信息傳遞給H5
    userLogin.loginCompleteBlcok = ^(){
        JSValue *jsValue = [self.jsContext evaluateScript:@"onLoginSuccess"];
//        JFUserInfoModel *user = [self getUserInfo];
        JSValue *result = [jsValue callWithArguments:@[@{@"userId":[JF_DEFAULTS objectForKey:@"userId"],@"token":[JF_DEFAULTS objectForKey:@"token"]}]];
        id  object=[result toObject];
        if(object!=nil){
            CLog(@"+++++++");
        }
    };
}

5、下面介紹直接調(diào)用H5的方法
5.1 無參數(shù)調(diào)用H5方法
在控制器添加一個(gè)按鈕

    UIButton * btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn1.frame = CGRectMake(0, [UIScreen mainScreen].bounds.size.height/2, 200, 50);
    btn1.backgroundColor = [UIColor blackColor];
    [btn1 setTitle:@"OC調(diào)用Js無參數(shù)" forState:UIControlStateNormal];
    [btn1 addTarget:self action:@selector(function1) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn1];

下面是js代碼，包括需要調(diào)用的方法

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<!--腳本-->
<script type="text/javascript">
    
    function JSCallOc1(){
        test1();
    }
function JSCallOc2(){
    test2('少停','iOS');
}
function aaa(){
    alert("OC調(diào)用了無參數(shù)的js方法");
}
function bbb(name,num){
    alert(name+num);
}

    </script>
<body>

然后用原生button的方法調(diào)用js的aaa()方法

#pragma OC調(diào)用JS方法
-(void)function1{
    [webview stringByEvaluatingJavaScriptFromString:@"aaa()"];
}

下面用原生button調(diào)用js方法并傳參數(shù)
先創(chuàng)建原生按鈕

-(void)function2{
    NSString * name = @"我是我";
    NSInteger num = 520;
    NSString *str = [NSString stringWithFormat:@"bbb('%@','%ld');",name,num];
    [webview stringByEvaluatingJavaScriptFromString:str];
@"bbb('%@','%ld')方法為

}
