Question

我是新手，需要一些在模拟器上运行的iPhone App的帮助。该应用程序与Build＆amp; amp;运行或构建＆amp;运行 - 断点关闭，但在使用Build＆amp; amp;调试 - 断点。任何帮助或想法将不胜感激。 Lon

细节：没有断点设置，永远不会得到任何可见的模拟器结果，似乎在初始化阶段爆炸，然后才能产生任何输出。应用程序的来源是DrinkMixer的例子，Dan＆amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; Tracey Pilone。

发出此错误消息：

Attaching to process 970.

您是否尝试过使用Instruments和NSZombie检测： http://www.markj.net/iphone-memory-debug-nszombie/
