推荐答案
您需要确保您的 AppDelegate.m
添加到目标设置中的编译源下.
You will need to make sure that your AppDelegate.m
is added under Compile Sources in your target settings.
为此,单击项目(Xcode 窗口的左上角)-> 单击Build Phases 选项卡-> Compile Sources 然后检查是否AppDelegate.m
实际上已添加到列表中.如果没有,请单击 + 按钮 -> 键入 AppDelegate.m
-> 选择然后添加.应该可以.
To do this, click on the project (left upper on your Xcode window) -> Click on Build Phases tab -> Compile Sources and then check to see whether AppDelegate.m
is actually added to the list. If not, click + button -> Type AppDelegate.m
-> Select and then Add it. That should do.
