我有一个可以在iPhone 3GS或4上部署的应用程序，它没有问题。但是，当我尝试将其部署在iPod Touch第3代和第4代时，它构建时没有任何错误，但除黑屏外没有任何显示。 这是我尝试安装应用程序时从设备获取的日志。

好的，我很容易解决这个问题。甚至我已经在pList中声明了我的nib文件，当我查看项目目标摘要时，不知何故只有iPad nib文件显示为主界面。所以我把它放在那里，现在它也在研究IPod。

看起来你正试图获得移动类型信息（大概是IMEI等），iPod Touch上也没有。
答案 2 :(得分：1)
我会寻找2个可能的原因：iOS版本，手机专用代码。
对于第一个选项，我尝试在不同版本上使用iphone模拟器（您可以在模拟器上更改它）。如果这看起来不像问题，那么尝试在代码中搜索可能使用手机特定内容的地方，例如尝试获取IMEI。
