问题 My team is developing a set of SDKs for barcode scanning, ID scanning and OCR. We use device's camera, specifically, AVCaptureSession , to obtain video frames on which we perform our processing. We're exploring new iOS 9 multitasking features Slide Over and Split View. Apple suggests opting out of these features for camera-centric apps, where using the entire screen for preview and capturing a moment quickly is a primary feature (reference). This is the approach the use in their sample app

问题 For iOS 7/8 when setting a text's parameters programmatically, it would display as expected when compiled/built to run on device. However, when testing my app for iOS9 in Xcode 7 all my views' frames are off or just plain not visible due to the text.font not recognizing the font. It's not a custom font per se, it's in Apple's library, and in fact, when you set a label via IB it displays properly, but when doing the same thing in code it simply displays the system font. Any ideas how to

问题 I'm trying to invite nearby players to a match, but the invite is either never sent or never received. GKMatchMaker startBrowsingForNearbyPlayersWithHandler works and returns nearby players that are on same wifi, but then I use findMatchForRequest and it returns a match without any players, and the players I try to invite never receive an invite notification. Here is my code. I start by authenticating the local player: GKLocalPlayer.localPlayer.authenticateHandler= ^(UIViewController

问题 I have created new version of CoreData model and migrated existing one to it.

问题 I'm developing an app in a new Xcode 8 and I noticed an obvious thing. Xcode generated me Core Data with the latest API references. So if I change deployment target to iOS 8 or 9, it conflicts and propose me to take in brackets: AVAILABLE my Core Data code. That means I have to write from scratch Core Data code from previous API. Does anybody have template for AppDelegate with both of them or maybe it's possible to make Xcode generate them? Thanks in advance! 回答1: Because no one should have

问题 I have noticed a that a uibutton is not showing in my app when run in iOS 9 (works fine in earlier OS versions). I know several have noticed a similar issue with storyboards (https://forums.developer.apple.com/thread/14003), though I am not using those and am instead building my view programmatically. There is no autolayout or autoresizingmask to worry about. UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(SUG_MARGIN, self.mainView.bounds.size
