ReplayKit Framework - Is it possible to only ask for permission once?

阅读更多关于 ReplayKit Framework - Is it possible to only ask for permission once?

问题 For Apple's new ReplayKit Framework in iOS 9 you have to get permission to access microphone and record screen. It seems like on when I run my test application in xcode on on every start up it re-asks for permission when I already granted permissions in a previous session. Is there a way to ask permission once (when a user starts up the app for the first time) and not have to ask again on every new session? Thanks ]1 回答1: Unfortunately, this permission shows up every single time you start

上一篇： ThreadLocal系列（二）-InheritableThreadLocal的使用及原理解析一、基本使用首先，TTL是用来解决ITL解决不了的问题而诞生的，所以TTL一定是支持父线程的本地变量传递给子线程这种基本操作的，ITL也可以做到，但是前面有讲过，ITL在线程池的模式下，就没办法再正确传递了，所以TTL做出的改进就是即便是在线程池模式下，也可以很好的将父线程本地变量传递下去，先来看个例子： // 需要注意的是，使用TTL的时候，要想传递的值不出问题，线程池必须得用TTL加一层代理（下面会讲这样做的目的） private static ExecutorService executorService = TtlExecutors.getTtlExecutorService(Executors.newFixedThreadPool(2)); private static ThreadLocal tl = new TransmittableThreadLocal<>(); //这里采用TTL的实现 public static void main(String[] args) { new Thread(() -> { String mainThreadName = "main_01"; tl.set(1); executorService.execute(() -> {

彻底理解RxJS里面的Observable 、Observer 、Subject

阅读更多关于彻底理解RxJS里面的Observable 、Observer 、Subject

最近闲来无事，常常重读Angular官方文档，颇能发现些有趣的地方。让我想起海澜之家的广告词：每次都有新体验。关于RXJS的基础概念， observable 和 observer ，我们好多次搞得头晕眼花。其实，看下面这简简单单的一行代码就懂了它们的关系： observable.subscribe(observer); observable 是数据源头，是生产者，是待订阅者，通过subscribe方法可以被订阅，而 observer 是消费者，是数据使用者，是订阅者。 observer其实是一个有三个回调函数的对象，每个回调函数对应一种 Observable 发送的通知类型（ next ， error ， complete ）。回调函数不必每次都提供三个。如果我们只提供了一个回调函数作为参数，subscribe会将我们提供的函数参数作为next的回调处理函数。 observable. subscribe() 是一个Subscription对象。 Subscription 就是表示Observable 的执行，可以被清理。这个对象最常用的方法就是unsubscribe方法。同时，它还有 add方法可以使我们取消多个订阅。我有一个比喻可以很好的理解这种订阅关系：现在有一家牛奶生产商，它们家的牛奶质优价廉，鲜美醉人。它在电视上发布广告，所有人都可以打它们的电话订奶。这个时候

How can I record and replay macros in Eclipse 3.5?

阅读更多关于 How can I record and replay macros in Eclipse 3.5?

问题 Which tool would you recommend for macro recording and replaying ? Is there a language as well ? I frequently switch between Eclipse and Emacs(actually Xemacs) for editing tasks. It would be nice if I didn't have to do as frequently. That would happen if a macro language/recorder were available in eclipse. It's available in Netbeans, so how come that is not a priority for eclipse ? 回答1: There is no current macro language on Eclipse: Practical Macro is not compatible with current 3.5 or 3.6

问题 I made a small game in Actionscript 3.0 and flash. When the player wins the game or is 'game over' the player should have a option to replay the game. So my question is: Is there a way to replay the whole movie with Actionscript? I know, i could reset the timeline back to 0, and re-instantiate all the classes, movieclips, var's ect... but i was wondering if anyone knows a easier solution. 回答1: You can remove the swfObject and add it again. Look here. This is the swfObject reference. 回答2:

Caching network calls using RxJava for some duration

阅读更多关于 Caching network calls using RxJava for some duration

问题 I am making a network using Retorfit + RxJava2 and I want to cache the response for 30 seconds. Any calls made after 30 seconds interval should get the latest results from server. I tried doing this using Replay operator but it still makes a network call every time I call subscribe. I am not an expert in RxJava so maybe my understanding of using Replay for caching like that is wrong. public Observable<Name> getName() { return retrofitBuilder.getName() .subscribeOn(Schedulers.io()) .replay(30,
