/********** 华丽分割线 ************/
俊哥语录：
这个类只要输入你的导航条实际高度，可以返回给你在各种适配情况下，导航条的frame和除导航条外的区域的frame
同样支持从IOS5到IOS7，隐藏和显示状态栏的情况，以及IPhone4和IPhone5的屏幕尺寸，以及支持IPhone和iPad两种设备
我写这个是为了在用XIB创建ViewController的情况下，用原来的BaseViewController不方便
BaseViewController在纯代码的开发过程中比较好用
我为了通用，加了- (void)setBarHeight:(CGFloat)barHeight;这个方法
用来设置你自定义的导航条高度，后面的计算都是基于这个高度的
另外两个方法看方法名字可以知道是干嘛的了
不用实例化，直接用两个类方法
后面跟你的导航条高度
注意，这个高度是不计算状态栏的
基本上可以通用任何情况
为了适配问题我死了不少脑细胞啊

使用的例子：
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationBarView.frame = [AdaptiveServer getBaseNavigationBarFrameWithNavigationBarHeight:44];
self.detailBackgroundView.frame = [AdaptiveServer getBaseBackgroundViewFrameWithNavigationBarHeight:44];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
[self.view addGestureRecognizer:tap];
}
