我使用Xcode7来调试App。
看起来step into行为就像step over,无法跳转到子过程的执行?每次只是跳转到源代码中的下一行。
如果我在 UIKit 方法中进行调试(我没有源代码),它会跳转到下一条指令。
最近我在使用Xcode(7.0)的beta版时遇到了一个问题.我无法听到通过此代码播放的声音:(它是来自Main.storyboard的ViewController,有一个连接的按钮buttonTouchUpInside())

我有CococaPods的问题.它们似乎是用Swift 2.0或一些新的Xcode功能编译的,因此不起作用:)因为我使用几乎几乎被遗弃且几乎不能维护的pod--我需要一些时间从它们迁移,或者它们迁移到它们Swift 2.0.如何强制Xcode 7以旧方式编译它们?:)

我正在努力学习C++,尤其是.指针及其算术.我正在使用XCode编译和运行我的程序.
下面我有两组代码,试图创建一个整数的3D数组.第一个代码编译并运行没有错误,但第二个代码编译没有错误,但在运行时生成EXC_BAD_ACCESS.
Bus Error: 10当我尝试使用g ++编译并从终端运行时,第二个代码生成.
任何人都可以告诉我为什么第二组代码没有成功运行虽然对我来说它看起来非常相似?
代码1:编译+运行成功
