问题 I'm using TestFlight to get beta users to test my iPhone app. I've never done this before and so I'm a bit concerned with the process. I've been following these steps to create my .ipa, but after step 3 I see lots of question marks in the organiser window (next to the name of my app to be specific). Should I be concerned. It seemed as if everything else worked. 回答1: Is your bundle display name set in the project info.plist file? Check that all values in info.plist are set correctly. 回答2: You

问题 Im using the Microsoft Graph to get calendar event with application permission. It works perfectly. Now Im trying to set up a subscription to listen to event changes however the normal v1.0 do not suport this. However beta, at least in the description, say it works. From the page: https://graph.microsoft.io/en-us/docs/api-reference/beta/api/subscription_post_subscriptions "Note: the /beta endpoint allows Application permissions as a preview feature for most resources." So I tried this with

问题 I am trying to perform cont. speech recognition using AVCapture on iOS 10 beta. I have setup captureOutput(...) to continuously get CMSampleBuffers . I put these buffers directly into SFSpeechAudioBufferRecognitionRequest which I set up previously like this: ... do some setup SFSpeechRecognizer.requestAuthorization { authStatus in if authStatus == SFSpeechRecognizerAuthorizationStatus.authorized { self.m_recognizer = SFSpeechRecognizer() self.m_recognRequest =

问题 Starting with the 5 minute quick start I've been playing around the angular2 beta and have run across a problem that has me stumped. Here is a dumbed down version that shows the problem I have.

问题 Using xcode 8 beta 6. Type override func prepare and I see this .. But I am looking for prepare(for segue: UIStoryboardSegue, sender: AnyObject?) Is this a bug?

问题 I am trying to plot the beta-gumbel distribution using R(software) by the following, The genreal idea is that, in the pdf of beta distribution, instead of plugging in x, we use the cdf of gumbel instead. But I couldn't get the right plot. x <- seq(-3, 3, length=100) Fx = pgumbel(x,loc=0,scale=1) y = dbeta(Fx,shape1=0.5,shape2=0.5) plot(x, y, type="l", lty=2, xlab="x value", ylab="Density",ylim=c(0,1)) 回答1: I don't believe you when you say that you didn't use any add-on packages: pgumbel() is

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Why is glReadPixels() failing in this code in iOS 6.0? I currently have an App in Appstore that uses the Cocos2D framework. For collision detection I am using glReadPixels. The screen only has white and black pixels and detecting a black pixel means collision. Everything works fine up to iOS 5.1.1 but in iOS6 Beta (all of them) glReadPixels stopped working. Now the RGB values returned by glReadPixels are always

问题 So you need a public URL with meta tags to represent an object in the OpenGraph, and one of the required meta tags is a URL property. When the action gets published, it links to this URL property. Let's say I'm on http://mysite.com/A .

Is there any way to link to a different URL (mysite.com/B) from a given OpenGraph object URL
