我希望能够有特定的代码块，例如#ifdef SOME_VARIABLE如果项目是在特定用户的计算机上构建的，则变量的值将在项目的构建时填充。
那可能吗？
我有一个UIViewController,ViewControllerA它是一个RootViewController类的模态视图控制器.
ViewControllerA然后呈现另一个模态控制器类,ModalViewControllerB我想知道是否调用ViewControllerA's
- (void)viewWillDisappear:(BOOL)animated
是由于ModalViewControllerB出现在屏幕上或因为ViewControllerA被解雇.
是否有内置的iOS方式来解决这个问题？
我正在尝试从命令行运行单元测试,但是当它们在Xcode 4.6中运行完全正常时它们会失败.我无法弄清楚失败的原因是什么:
这是我正在使用的命令:
xcodebuild -sdk iphonesimulator -project myproject.xcodeproj
-scheme 'MyProjectApplicationTests'
-configuration Debug clean build
RUN_UNIT_TEST_WITH_IOS_SIM=YES TEST_AFTER_BUILD=YES TEST_HOST=''
我在测试中没有使用NSURL或'initFileURLWithPath'.这是错误:
