    6.2 系统主界面iPad开发从入门到精通本章实例的的源码保存在“:daima6Bus”,默认的系统主界面是线路查询视图,在线路查询视图CBus_LineView.xib顶部设置了一个查询表单,在下方列表显示系统内的公交线路。线路查询视图的UI界面如图6-1所示。

    6.2.1 线路查询视图实现文件CBus_LineViewController.h的代码如下所示。

    #import <UIKit/UIKit.h> @interface CBus_LineViewController : UIViewController <UITableViewDelegate, UITableViewDataSource,UISearchDisplayDelegate, UISearchBarDelegate>{   UITableView    *busLineTableView;   NSMutableArray  *filteredListContent; } @property(nonatomic, retain) IBOutlet UITableView   *busLineTableView; @property(nonatomic, retain) NSMutableArray *filteredListContent; @end 文件CBus_LineViewController.m是文件CBus_LineViewController.h的实现,功能是载入设置的视图界面,显示一个搜索表单,并在表单下方列表显示30条公交线路信息,并且可以根据用户输入的搜索关键字来显示搜索结果。文件CBus_LineViewController.m的具体实现代码如下所示。 #import "CBus_LineViewController.h" #import "CBus_LineDetailViewController.h" #import "CDataContainer.h" @implementation CBus_LineViewController @synthesize busLineTableView,filteredListContent;
