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"
