如何设置iPhone所需的最低操作系统

Question

I have to check whether my app is compatible with iOS 4.0 or not.

I have tried looking out for certain forums but all I can see is to change the iOS deployment target. I have done doing so also but still my app is running fine. I have changed my deployment target to 3.0 but still it works fine. Since I have used Gesture recognition which was introduced later. It must crash my app (but still it is working fine).

So I want to know Is there any other way out to check my compatability.

Or is it the problem because I am running it on Simulator rather than on device(my device has iOS version 4.2).

Any comments or answers are really appreciated.

Answer 1

If you have an iPhone that is certified for distribution you can just run it on your device and test your firmware versions from there. Hope that helps...

Answer 2

是的，这就是您的应用程序不通过ios版本4.2的模拟器运行而导致崩溃的原因。因为现在您的ios版本在模拟器上进行了更新，因此您可以通过它测试手势识别。您是正确的。
