iPhone开发工具之将XIB文件转换为Objective-C源程序
nib2objc是一个小巧的转换工具，可以将XIB文件自动转换为Objective-C的源代码文件。
通常，考虑到程序的效率时，才将XIB直接转换为源代码文件。但是这样一来，通过Interface Builder设定的实例变量与行为方法的接续也没有了，需要从新手写。但是，该工具的源代码是公开的，稍加修饰，就能完成大部分工作。
使用的时候，首先下载的工程代码并用XCode编译一下，会生成一个命令行程序文件 nib2objc。然后如下所示执行转换：
- $ nib2objc WebView.xib > WebView.m
像是上面view转换后会输出以下代码:
- UIBarButtonItem *view39 = [[UIBarButtonItem alloc]
- initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
- view39.frame = CGRectMake(0.0, 0.0, 0.0, 0.0);
