ios6

问题 This problem comes when I build an app targeting iOS 5 or 6, but run it on iOS 7. If I have a controller in a navigationController that is a part of a tabBarController, and I do the following: controller.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController:testController animated:YES]; A strange vertical positioning animation occurs. I would instead like the new controller (with the bottom bar hidden) to push or pop on the navigation controller pushing the tab bar out

问题 I am new to iOS . I was installing latest XCode with SDK 6.0 in it. I have been successfully testing my app developed using SDK 6.0 on simulator. Now i want to test it on real device without developer program account. To do that, i use Jailcoder . I have an iPhone 3GS , with AppSync 5.0+ installed. I have tried "Quick XCode Patch" and "Patch My Project" . However i still get signing error. It said, CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 6.0' Seems

问题 I just discovered some strange behaviour on iPad with the new iOS 6. I'm testing a web app for offline usage. The web app is no more than a static website with a cache manifest, so no special frameworks like sencha touch or tools like phnoegap are used. Just HTML, CSS and JavaScript and a cache.manifest. The App worked fine before: I could save the website to the home screen. When I opened it from there, all the data would be downloaded for caching. At the end of the download the pop-up would

问题 There is precious little documentation on AVAudioMix and MTAudioProcessingTap, which allow processing to be applied to the audio tracks (PCM access) of media assets in AVFoundation (on iOS). This article and a brief mention in a WWDC 2012 session is all I have found. I have got the setup described here working for local media files but it doesn't seem to work with remote files (namely HLS streaming URLs). The only indication that this is expected is the note at the end of this Technical Q&A:

问题 A question here: Xcode 4.5 corrupting XIBs? illustrates the problem and solution for xcode 4.5 creating nib files that can not run on ios5. Does anyone have a solution to prevent the auto layout checkbox from being defaulted to on? I'm worried that in the process of development, I will forget to unchecked that box. 回答1: There's a way, but it's kinda convoluted and, I might add, not recommended. You can open your template files located in: /Applications/Xcode.app/Contents/Developer/Platforms

问题 Update: Added bug 12408800 on Apple's site. I am copying some one or multiple UIImage to the UIPasteboard, and it's been working like gangbusters.. until my phone upgraded to iOS 6. Xcode 4.5 with iOS 5.1 - OK Xcode 4.4 with iOS 6.0 - Also OK (according to this post) Xcode 4.5 with iOS 6.0 - FAIL (also tested distributing via TestFlight, for what it's worth - still fails) Here's my code (super basic, etc): // add image to clipboard UIImage *image = [[UIImage imageNamed:@"testimage"]; [

问题 iOS6 ajax POST request caching is becoming a huge problem for our webApp. Most of our users have added the app to the home screen. Ever since the upgrade, most of the POST requests to the backend are not working and data is stale from over 6 days ago and counting. We are aware of two workarounds to resolve this, one is to change every POST request so that it's different by adding a timestamp or some random input to it, and the second is to disable caching on the webserver. Both workarounds
