URL Scheme

URL Scheme是app跳转使用的

 

一般使用情景

App之间跳转
网页跳转App


优点
设计简单、方便


缺点
Schema 无法判断是否安装 App,如果要判断需要JS来判断(判断是否超时)
Schema 被很多 App 禁止

效果

  这里写个自定义的URL Scheme、放在备忘录里面

AppDelegate 关键代码

// 热启动 冷启动 调用
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
    // 因为使用了观察者，冷启动的时候，需要等初始化完成
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.50 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        NSString *hostUrl = url.host;
        NSDictionary *paras = [url getURLParameters];
        NSLog(@"AppDelegate scheme url = %@",hostUrl);
        NSLog(@"AppDelegate scheme 参数 = %@", paras);
        
        LinkModel *model = [LinkModel new];
        model.url = hostUrl;
        model.para = paras;
        [[NSNotificationCenter defaultCenter] postNotificationName:@"Scheme" object:model];
    });
    return YES;
}

 

SceneDelegate 关键代码

如果没有使用SceneDelegate，请忽略

// 冷启动调用
- (void)scheme:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions
{
    // 冷启动的时候，需要等初始化完成
    for (UIOpenURLContext *context in connectionOptions.URLContexts) {
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.50 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            NSString *url = context.URL.host;
            NSDictionary *paras = [context.URL getURLParameters];
            NSLog(@"SceneDelegate scheme url = %@",url);
            NSLog(@"SceneDelegate scheme 参数 = %@", paras);
            
            LinkModel *model = [LinkModel new];
            model.url = url;
            model.para = paras;
            [[NSNotificationCenter defaultCenter] postNotificationName:@"Scheme" object:model];
        });
    }
}




// 热启动调用
- (void)scene:(UIScene *)scene openURLContexts:(NSSet<UIOpenURLContext *> *)URLContexts
{
    NSString *url = URLContexts.allObjects.firstObject.URL.host;
    NSDictionary *paras = [URLContexts.allObjects.firstObject.URL getURLParameters];
    NSLog(@"SceneDelegate scheme url = %@",url);
    NSLog(@"SceneDelegate scheme 参数 = %@", paras);
    
    LinkModel *model = [LinkModel new];
    model.url = url;
    model.para = paras;
    [[NSNotificationCenter defaultCenter] postNotificationName:@"Scheme" object:model];
}

AppDelegate 关键代码

        // 因为使用了观察者，冷启动的时候，需要等初始化完成
        DispatchQueue.main.asyncAfter(deadline: .now()+0.5, execute:{
            let hostUrl = url.host

Universal Link

Universal Link是app跳转使用的

 

一般使用情景

App之间跳转
网页跳转App


优点
直接点击不会出现弹窗、跳转方便
自动判断App有没有安装、跳转到App Store


缺点
配置麻烦 需要SSL证书、测试需要等一段时间
网络不好的情况下、第一次下载成功打开情况下是无法跳转的。原因是Universal Link需要下载apple-app-site-association文件。网络不好会导致下载失败

 

 

效果

因为要上传文件给https的服务器、效果图就使用项目的图了

  这里写个测试的URL、放在备忘录里面

https://www.demo.com?id=1&name=123&age=18

 

Universal Link 实现

Universal Link配置

添加Universal Link

  编写url

  编写apple-app-site-association文件

// appID 格式是teamid.Bundle id
// paths 同意跳转的路径
{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "teamId.cn.hahn.study.studyOC",
                "paths": [ "*" ]
            }
        ]
    },
    "webcredentials": {
       "apps": [ "teamId.cn.hahn.study.studyOC" ]
    }
}

teamId查看

将apple-app-site-association文件上传该文件到你的域名所对应的根目录或者.well-known目录

苹果为了方便开发者，提供了一个网页来验证我们编写的这个apple-app-site-association是否合法有效，进入验证网址进行验证：

        NSDictionary *paras = [userActivity.webpageURL getURLParameters];

Deferred Deep Linking

Deferred Deep Linking是延迟深度链接、一般使用Universal Link 或 URL Scheme在没有下载的情况只能跳转到App Store。下载完成以后Universal Link 或 URL Scheme的参数是没有办法调用的，需要重新点击。

  Deferred Deep Linking是可以保存Universal Link 或 URL Scheme的参数的技术。一般是是使用第三方的，比如Appflyer等。这些集成大平台的SDK。

有一个取巧的方法，就是在web里面弄一个下载界面。web下载按钮弄一个复制保存参数。App读取粘贴板。
