iOS 推送问题

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    if (application.applicationState == UIApplicationStateActive) {
        [self gotoUrl:userInfo];
    }else{
        [self showPushArticle:userInfo];
    }
    completionHandler(UIBackgroundFetchResultNewData);
}

showPushArticle 函数

- (void)showPushArticle:(NSDictionary *)userInfo
{
    if (userInfo == NULL) {
        return;
    }
    
    NSDictionary *article = [userInfo objectForKey:@"ext"];
    if(article)
    {
        NSString *url  = [article objectForKey:@"l"];
        
        if(![url hasPrefix:@"https://"]){
            return;
        }
        
        PTWebViewController *viewcontroller = [[PTWebViewController alloc] init];
        viewcontroller.webURL = url;
        [viewcontroller setNavigationTitle:@"推送新闻"];
        [self.drawerController.centerNavigationController pushViewController:viewcontroller animated:YES];
    }
}

push 的 json 格式是:

{"aps":{"alert":"title","badge":1,"sound": "default"},"ext":{"l":"https://example.com"}}

不知道哪位遇到过同样的问题，麻烦指教一下

你先确定第二种情况(App Store 版本)，App 是没在后台运行的，还是在后台运行的？
如果没后台运行的，你需要从- application: didFinishLaunchingWithOptions: 中取出推送的内容
```
NSDictionary * remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
```

另：
if(![url hasPrefix:@"https://"]){
建议改成
if(![url hasPrefix:@"http"]){
这样 url 是 http 也可以调起 WebView 控制器

application: didFinishLaunchingWithOptions:中也是写了的，代码如下：
```
NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (userInfo) {
[self showPushArticle:userInfo];
}
```
无论 app 在后台运行还是在前台都不会跳转，但是接收没有问题

确定两种版本都是通过 api 或者网页发送的数据么

@showme1121 肯定是一样的，都是使用同样的数据
