一，效果图。
二，。project文件例如以下图所看到的：
三，DataModel.h
#import <Foundation/Foundation.h>
@interface DataModel : NSObject
{
NSArray *myData;
}
-(NSString *)getNameAtIndex:(int)index;
-(int)getRowCount;
@end
DataModel.m
//数据库文件
#import "DataModel.h"
@implementation DataModel
-(id)init
{
if (self=[super init]) {
myData=[[NSArray alloc]initWithObjects:@"first",@"second",@"three",@"four", nil];
}
return self;
}
//显示数组中数据
-(NSString *)getNameAtIndex:(int)index
{
return (NSString *)[myData objectAtIndex:index];
}
//显示行数
-(int)getRowCount
{
return (int)[myData count];
}
@end
四。ViewController.h
#import <UIKit/UIKit.h>
#import "DataModel.h"
@interface ViewController : UIViewController
<UITableViewDataSource,UITableViewDelegate>
{
UITableView *myTableView;
DataModel *model;
}
@end
ViewController.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//初始化数据
[self initData];
//初始化界面
[self addBackgroundView];
}
#pragma -mark -functions
//初始化数据
-(void)initData
{
model=[[DataModel alloc]init];
}
//初始化界面
-(void)addBackgroundView
{
myTableView=[[UITableView alloc]initWithFrame:CGRectMake(0, 100, 320, 300)];
myTableView.dataSource=self;
myTableView.delegate=self;
[self.view addSubview:myTableView];
}
#pragma -mark -UITableViewDelegate
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [model getRowCount];
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 40;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=@"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text=[NSString stringWithFormat:@"%@",[model getNameAtIndex:(int)indexPath.row]];
return cell;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
