ios8

问题 Looking through all the solutions given to similar questions, I have been trying to get the statusBar to show/hide with a tap gesture. I have set View controller-based status bar appearance = NO in the plist. I have tried the following code in my DataViewController (page view controller) AND in the RootViewController : let app = UIApplication.sharedApplication() app.setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.Fade) and it doesn't work.

问题 I have a fullscreen HTML5 web app for iPads and have just installed IOS 8 to try it out and it all works perfectly until you power the iPad off and back on.

Anyone else noticed this or come up with a work around? 回答1: This seems to me resolved in the iOS8.1.1 update. 回答2: I noticed

问题 I am trying to react on silent push messages. I registered my app for the two background modes in my plist file. I am sending the following json to my app: { "aps": { "content-available": 1 }, "Bla": "Blub" } If my app is in foreground, everything works. As I am receiving the push I execute a function in my code. If my app is in background and plugged to my Mac or ac, everythings fine as well...
