Xcode 4.5 Storyboard 'Exit'

由 混江龙づ霸主 提交于 2020-01-27 08:53:26
问题 I have just installed Xcode 4.5 for iOS6 support, and I have seen a new icon called 'Exit' in my Storyboard, listed under my view controllers along with 'First Responder' etc. A little green icon labeled 'Exit'. I can find anything on it nor work out how it can be used. Anyone know anything about it, how it works, what its for? 回答1: This is called an " Unwind Segue ". Unfortunately there's no documentation for this so far except a brief mention on XCode 4.5 new features list that states:

Disable scrolling when changing focus form elements ipad web app

由 不想你离开。 提交于 2020-01-26 09:42:18
问题 I have a web app. I'm trying to disable/prevent the scrolling that occurs when you focus on different form inputs (i.e. the scrolling that occurs as you advance through input elements in a form). I've already disabled scrolling with this: <script type="text/javascript"> $(document).ready(function() { document.ontouchmove = function(e){ e.preventDefault(); } }); </script> To add a little more info - I have a few "slides" that my page consists of. Each are 768x1024 and they are "stacked" on the

Is there a better way to do this? 回答1: There is a better way in OS5. Forget about

Adding UIViewController.view to another view causes orientation problems

由 浪子不回头ぞ 提交于 2020-01-25 08:31:05
问题 Short version: I'm alloc/init/retaining a new UIViewController in one UIViewControllers viewDidLoad method, adding the new View to self.view. This usually works, but it seems to mess up orientation change handling of my iPad app. Longer version : I'm building a fairly complex iPad application, involving a lot of views and viewcontrollers. After running into some difficulties adjusting to the device orientation, I made a simple XCode project to figure out what the problem is. Firstly, I have

bootstrap error ios simulator

由 泪湿孤枕 提交于 2020-01-25 03:59:33
问题 I tried to launch my project, but i got this error while compiling it on the simulator.WorkOut is the name of my project. Couldn't register com.AE557593PG.WorkOut with the bootstrap server. Error: unknown error code. 回答1: Try making sure the app isn't running on the simulator already. Worst case scenario, quit and restart both Simulator and Xcode. That's always fixed this for me. 来源： https://stackoverflow.com/questions/4316760/bootstrap-error-ios-simulator

SQLite problem “unable to open the database file”

由 旧城冷巷雨未停 提交于 2020-01-25 02:19:10
问题 I come to you after a lot of hours googling and reading other discussions about SQLite on StackOverflow, but I definitely can't find any explanation to my problem, so here it is : The context : I'm developping an application for iPad wich has to deal with some "large" amounts of data, in several occasions. In one of them, I must import points coordinates from a .kml file (Google's xml for geographical data) into my database, in order to reuse them later with a MKMapView and load them faster

CLLocation Manager not updated when App is in Guided Access mode

问题 I kept Guided Access for iPad app. When the app is launched it asks for user's current location using CLLocationManager .This is working under Normal mode and updates user current location. But under Guided Access, popup ("Allow to access your location") is not shown and authorizationStatus is always kCLAuthorizationStatusNotDetermined and doesn't update current location of user . Couldn't understand what could be the problem.Searched a lot but couldn't find it. ViewController.m : - (void
