iPhone固件 [英] iPhone firmware

问题描述

我使用iPhone OS 2.2开发了一个iPhone应用程序.它在模拟器中可以正常工作.当我使用iTunes(ipa文件)在iPhone中安装该应用程序时，该应用程序无法正常工作.

I developed one iPhone application using iPhone OS 2.2. It works fine in the emulator. When I install the application in my iPhone using iTunes (ipa file), it isn't working.

一件事:我的iPhone固件是3.0，是问题吗?

One thing that : my iPhone firmware is 3.0, is it the problem?

iPhone OS 3.0(在实际硬件上)是否可以运行在iPhone OS 2.2上开发的应用程序?

Does iPhone OS 3.0 (on real hardware) work the application that are developed on iPhone OS 2.2 ?

推荐答案

否，您不需要从Apple iphone开发人员网站下载iPhone 3.0软件开发人员工具包(SDK).此页面上有下载链接. http://developer.apple.com/iphone/

no you will need to download the iPhone 3.0 software developers kit (SDK), from the apple iphone developers site. There is a link to download on this page. http://developer.apple.com/iphone/

我相信您还需要注册开发人员程序才能在模拟器之外实际运行您的应用程序.我认为个人注册费用为$ 100

I believe you also need to sign up to the developers program to actually run your application outside of the simulator. I think the cost to signup for an individual is $100
