ios8

问题 Since iOS 8 was released the default device type for simulator became iPhone 6. And even if I manually change the device type using Hardware > Device menu, on the next launch (using rake simulator ) the simulator will revert to iPhone 6. I wonder if there is any rake options, or some other settings to force the device type. PS. I know that there are ways to force a non-retina iPhone and a way to launch the iPad simulator instead of the iPhone one, but I'm interested in selecting between 5/6/6

问题 My app was building fine in Xcode 6 Beta 4. I updated to Beta 5 today and ran into 2 errors: The file “Storyboard_iPad-SBPartialInfo.plist” couldn’t be opened because there is no such file. Command /Applications/Xcode6-Beta5.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/ibtool failed with exit code 255 What is that SBPartialInfo.plist? I could not search for it via spotlight. My Storyboard files are storyboard_iphone and storyboard_ipad 回答1: I was also

问题 I've just updated to Xcode 6/iOS 8 SDK and my location service simulation in simulator started not working. It was fine before I updated (I'm currently unable to test on real device). Now, when I select a location for simulation, nothing happens. Delegate's -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations method is not called. I've restarted Xcode, cleaned the build folder, nothing changed. Why can this happen? 回答1: Since IOS 8 you need to ask for

问题 Now XCode 6 with iOS 8 SDK is out, we can talk about stuff. I tried to use custom activities with UIActivityViewController on iOS 7, everything worked fine. But on iOS 8, when custom activities are shown, there is "more" button sitting next to them and clicking on this button show exactly the same custom activities. Did anyone find a workaround to remove this button? I couldn't find any solution yet. 回答1: There is nothing to workaround. The "More..." button lets the user reorder the icons.

问题 I am looking for a proper way to handle a invalid argument during a initialization. I am unsure how to do it using Swift as the init has't a return type. How can I tell whoever is trying to initialize this class that you are doing something wrong? init (timeInterval: Int) { if timeInterval > 0 self.timeInterval = timeInterval else //???? (return false?) } Thank you! 回答1: Use a failable initializer . Such an initializer looks very similar to a regular designated initializer, but has a '?'

问题 @IBAction func operate(sender: UIButton) { if let operation = sender.currentTitle { if let result = brain.performOperation(operation) { displayValue = result } else { displayValue = 0.0 } } } I am new to coding so pardon my coding format and other inconsistencies. I have been trying out the iOS 8 intro to swift programming taught by Stanford university and I have ran into a problem with the modified calculator. I get three errors. The first one is a swift compiler warning - at if let result =

问题 My app crashes on some iPhone 5S device (only some) with the error: Fatal Exception: NSInternalInconsistencyException Unexpected error: Error Domain=NSCocoaErrorDomain Code=4097 "The operation couldn’t be completed.

问题 Here is my storyboard I'm using autolayout, and NOT using size classes. When I ran it on iPhone 5s, it works fine.(both portrait and landscape) But when I ran it on iPhone 6 plus (portrait), it's not aligning properly. on iPhone 6 plus (landscape), it's worse. I know I can use -widgetMarginInsetsForProposedMarginInsets: to set the margin, but in that case I will need to customize the margin for every device. That would be horrible :( So is there a way to align the subview to the title less

问题 When a UISearchController's search bar becomes active, it hides the view's navigation bar. I'd like to have the search bar active below the navigation bar. In iOS 7 there was a good way to do this for UISearchDisplayController here: https://stackoverflow.com/a/12529945/3799720 But now in iOS 8 with UISearchController I can't figure out how to do this. 回答1: This might have something to do with the UISearchController hidesNavigationBarDuringPresentation property. 回答2: yourSearchController
