ios中uitableview显示两列或多列数据

我们知道在ios6以后，系统多了个UICollectionView可以显示多列数据，就像android的gridview，那么在ios6以前，我们如何实现呢？这里，我们通过一个tableview来实现。

它的原理是这样的，总共有多少条数据，除以要显示的列数，用来定义cell的行数，然后在一行中初始化这行中有多少列数据。。。。。。。

写个简单点的DEMO。。。结构如下：



这里，我们先定义一个头文件，InfoConfig.h，在这个头文件里我们定义相关的宏。。。

#ifndef TestTableTwoRow_InfoConfig_h
#define TestTableTwoRow_InfoConfig_h

#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)

#define rowcellCount 2
#define RMarginX 0
#define RMarginY 0

#endif

然后我们定义一个数据模型SubCollectionsInfo类，这里只是封装了一些属性，提供set/get方法。。。。

@interface SubCollectionsInfo : NSObject
{

    
    NSString *_iconString;
    NSString *_niandaiString;
    NSString *_titleString;
    NSString *_contentString;
    NSString *_xmlFile;
    NSString *_idString;
    NSString *_nbidString;
    NSString *_timenmString;
    NSString *_stimeString;
    NSString *_etimeString;
    NSString *_zipFile;
    NSString *_md5String;

}

@property(nonatomic,copy) NSString *iconString;
@property(nonatomic,copy) NSString *niandaiString;
@property(nonatomic,copy) NSString *titleString;
@property(nonatomic,copy) NSString *xmlFile;
@property(nonatomic,copy) NSString *idString;
@property(nonatomic,copy) NSString *contentString;
@property(nonatomic,copy) NSString *nbidString;
@property(nonatomic,copy) NSString *timenmString;
@property(nonatomic,copy) NSString *stimeString;
@property(nonatomic,copy) NSString *etimeString;
@property(nonatomic,copy) NSString *zipFile;
@property(nonatomic,copy) NSString *md5String;

@property(nonatomic,assign) BOOL isselected;
@property(nonatomic,assign) BOOL isdownload;

@end

然后我们自定义一个tablecell继承于UITableViewCell，，，封装一个view,用来展示我们的界面

。。。。。具体可以看代码

最后，我们初始化一个tableview,加载相应的数据上去。。。

- (void)viewDidLoad
{
    [super viewDidLoad];
	
    
    if (iPhone5) {
        
        self.view.frame=CGRectMake(0,0, 320, 568);
        
    }else
    {
        
        self.view.frame=CGRectMake(0,0, 320, 480);
        
    }
    
    [self.view setBackgroundColor:[UIColor whiteColor]];
    
    
    self.navigationItem.title=@"大帝";
    
    [self initData];
    [self initUI];

    
}

-(void) initData
{

    dataArray=[[NSMutableArray alloc] init];
    
    for (int i=0; i<10; i++)
    {
        
        SubCollectionsInfo *info=[[SubCollectionsInfo alloc] init];
        
        info.niandaiString=@"王子大人";
        info.titleString=@"大帝";
        info.contentString=@"好人";
        info.iconString=@"celltouxiang.jpg";
        
        [dataArray addObject:info];
        
        [info release];
        
    }

}

-(void) initUI
{

    testTableView=[[UITableView alloc] init];
    [testTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width,self.view.frame.size.height)];
    testTableView.separatorStyle=UITableViewCellSeparatorStyleNone;
    [testTableView setBackgroundColor:[UIColor clearColor]];
    
    [self.view addSubview:testTableView];

    testTableView.dataSource=self;
    testTableView.delegate=self;

    
}

-(void)cellviewTaped:(UITapGestureRecognizer *)recognizer
{
	
    int tag=[recognizer view].tag-8000;
    
    NSLog(@"%d",tag);
    
   
    
}

#pragma tableview
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    
    
    return (dataArray.count-1)/rowcellCount+1;
    
    
}

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    
    static NSString *CellIdentifier1 = @"Cell1";
    
    
    SubCollectionsCell2 *cell =(SubCollectionsCell2 *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
    
    if (cell == nil)
    {
        
        cell = [[[SubCollectionsCell2 alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1] autorelease];
        
        cell.backgroundColor=[UIColor clearColor];
    }
    
    
    NSUInteger row=[indexPath row];
    
    
    SubCollectionsInfo *subInfo=nil;
    
    for (NSInteger i = 0; i < rowcellCount; i++)
    {
        
        //奇数
        if (row*rowcellCount+i>dataArray.count-1)
        {
            
            break;
            
            
        }
        
        subInfo=[dataArray objectAtIndex:row*rowcellCount + i];
        
        if (i==0)
        {
            
            [cell.cellView1.iconImageView setImage:[UIImage imageNamed:subInfo.iconString]];
            [cell.cellView1.niandaiLabel setText:subInfo.niandaiString];
            [cell.cellView1.titleLabel setText:subInfo.titleString];
            [cell.cellView1.contentLabel setText:subInfo.contentString];
            cell.cellView1.tag=8000+row*rowcellCount + i;
            
            UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(cellviewTaped:)];
            [ cell.cellView1 addGestureRecognizer:tapRecognizer];
            [tapRecognizer release];
            
        }
        else
        {
            
            [cell.cellView2.iconImageView setImage:[UIImage imageNamed:subInfo.iconString]];
            [cell.cellView2.niandaiLabel setText:subInfo.niandaiString];
            [cell.cellView2.titleLabel setText:subInfo.titleString];
            [cell.cellView2.contentLabel setText:subInfo.contentString];
            cell.cellView2.tag=8000+row*rowcellCount + i;
            
            UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(cellviewTaped:)];
            [ cell.cellView2 addGestureRecognizer:tapRecognizer];
            [tapRecognizer release];
            
            
        }
        
        
    }

    
    cell.selectionStyle = UITableViewCellSelectionStyleNone;
    
    
    return cell;
    
}

-(CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    
    //    UITableViewCell *cell=[self tableView: tableView cellForRowAtIndexPath: indexPath];
    //
    //
    //    return cell.frame.size.height;
    
    
    return 160;
    
    
}

- (void)dealloc
{
    
    [super dealloc];
    
    
    [testTableView release];
    
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

效果如下图：
