iphone - iphone OS lower than 4 ==> Testing iAd?

Question

I implemented iad to my app (sdk 4), i set the target to be able to run OS 3 and higher now i need to test and make sure that devices with OS 4 lower won't crash because of iAd. Is there a way to go back to iphone OS 3.2 to test this. Where can i download it, apple has removed it from their website.

Answer 1

当您安装 sdk 4 时，sdk 3.2 应该仍然存在，因为那是单独的 iPad OS，在代码编辑器的左上角只需选择下拉菜单并选择 3.2（设备或模拟器）
