问题 If I create an App for the iPhone (OS 3) will it run without modification on an iPod Touch or will I need to create a separate binary? If it is the same runtime, does it just have stubs for the iPhone only features or do you have to check feature by feature using UIDevice to ensure the particular class/method is supported on the device to avoid a crash? Sorry for the elementary questions, can't find a simple explanation of this anywhere. Cheers Dave EDITED: Based on discussions below: How can

问题 I am looking for help in integrating Captuvo SL22 SDK within appcelerator. The Captuvo SDK comes with the Captuvo scanner/msr for ipod. I am trying to use Captuvo SDK in a custom module and call it in the main app. I am able to establish a connection with the Captuvo Device by using the following code in the custom module startup method: -(void) startup{ self.captuvo = [Captuvo sharedCaptuvoDevice]; [self.captuvo addCaptuvoDelegate:self]; [self.captuvo startDecoderHardware]; } -(void)

问题 I have registered 2 devices in App program portal. Only I have a Mac & device to download the App for testing. The other user does not have a Mac. But he has an iPhone. Is it possible for the other user to have the App downloaded for testing so we can discuss if we need any modifications before making the App live on App Store for public. 回答1: Use Ad Hoc distribution. 回答2: Follow the steps here to package the app for the tester. Publishing Applications for Testing Then the tester should

问题 The crash log returned when your app has an error on iOS is wonderful however it would be 100 times better if it contained the console output from when your app started as part of the log. Is there a way to automatically have that information in the crash log, or have a semi-automatic system that testers could use when sending in crash logs? 回答1: I think you might want to take a look at http://apphance.com. It's exactly what you are looking for - including capability of sending problem

问题 When I started on my current project, there was already an App in the App Store. This App was iPhone only. My first task was to test and build a version that also ran on an iPod Touch. About 3 weeks ago Apple removed the option on iTunes connect to set the device requirements. And sent an email out to all developers: "The App Store requires that you provide metadata about your application before submitting it. While most of this metadata is specified using the iPhone Developer Program Portal,

问题 I have released my first app on the iOS App Store a few days ago and told my friends to download it. However, they have told me that it is not compatible with the iPod Touch 2G running iOS 4.2.1. Why is this? And how do I fix this? I am using Xcode 4.2 with iOS SDK 5.0, but my deployment target is iOS 4.0, so it should work. On the iTunes page for my app, it says: Requirements: Compatible with iPhone 3GS, iPhone 4, iPhone 4S, iPod touch (3rd generation), iPod touch (4th generation) and iPad.

问题 I'm finishing off an app for iOS 3.0 and up to run on the iPhone and iPod Touch. It's working fine on iOS4.0 and up, but when I backtest it on a second generation iPod Touch running iOS 3.0 the launch image shows and I'm met with the following: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSKeyedUnarchiver initForReadingWithData:]: incomprehensible archive (0x4e, 0x49, 0x42, 0x41, 0x72, 0x63, 0x68, 0x69)' 2012-01-15 09:35:53.025 MyApp[3026:207]

问题 I am making an app that uses a lot of fairly big image files. I notice it crashes when they all get loaded on my iPhone 3G (128 mb ram), but not when I test it on a 3rd gen iPod (256 mb ram). So I assume there must be some percentage that is allowed for each app to use? My app has about 30 images at about 440k each loaded so 13.2mb. I didn't think that would be too much. They need to be swapped in and out pretty quickly, so releasing the ones not in use from memory doesn't seem like a good

问题 This question was migrated from Ask Different because it can be answered on Stack Overflow. Migrated 6 years ago . This question is out-dated. Mavericks is released and everything works fine with Xcode 5 and iOS 6 on an iPod 4th gen. I'm thinking about upgrading my OS X to Mavericks, but I still want to keep developing my iOS app. I read on the internet that Xcode 4.6.3 is not compatible with Mavericks (OS X 10.9). So, this would force me to use the new Xcode 5. However, Xcode 5 comes along

问题 Is there a way to find out the maximum number of simultaneous touches on an iOS device (iPhone, iPod Touch, iPad) ? I've read here and there that iPhone can handle 5 while the iPad can handle 11, but I haven't found an official way (through a function call, say) to confirm this. 回答1: By testing it! See here for videos and source: http://mattgemmell.com/2010/05/09/ipad-multi-touch There's no public API to request that information from the hardware. 回答2: iPhone can register 5 touch points on
