Libraries and frameworks are designated as Required by default, but you can change this designation to Optional.
Required libraries must be present on the host computer for the product to load.
Optional libraries do not have to be present for the product to load.
A Required framework will always be loaded into memory, but an Optional framework will be loaded only if needed.
The initial load of the application will be faster if a large library that is never needed is designated as Optional.

之前认为Apple 的iOS 设计的要比 Android 稳定,我错了吗?
下载的许多客户端程序/游戏程序,经常会Crash,是程序写的不好(内存泄漏?刚启动也会吗?)还是iOS本身的不稳定!!!
如果在Android手机中可以简单联接到ddms,就可以查看系统log,很容易看到程序为什么出错,在iPhone中如何得知呢?试试Organizer吧,分析一下Device logs,也许有用.
