大部分有一点其他平台开发基础的初学者看到XCode，第一感想是磨拳擦掌，看到Interface Builder之后，第一感想是跃跃欲试，而看到Objective-C的语法，第一感想就变成就望而却步了。好吧，我是在说我自己。 如果你和我一样，对苹果相关的开发：Mac OS X或是iPhone有兴趣，但是第一时间看到Objective-C就会头疼并伴有发烧症状的话，疗效比较好的快速治疗...

Interface Builder参与的内存管理问题:如果一个变量在类中被定义为了 IBOutlet 那么你无需对其进行实例化，xib载入器会对其初始化。如果一个变量在类中被定义为了 IBOutlet 那么你必须负责将其释放。xib载入器不会帮忙*切不要初始化两回，内存会溢出，而且对象锁定也会出错。--------------------------------------...
