推荐答案

在ios UITableView中，您只能有一个列/单元格。如果您想要更多属性，则需要在同一单元格中通过子计算UITableViewCell来创建自定义表格视图单元格。在界面构建器中，您可以自定义布局。指南： http://adeem.me/blog/2009/05/30/iphone-sdk-tutorial-part-6-creating-custom-uitableviewcell-using-interface-builder-uitableview/

In ios UITableView you can only have one column/cell. If you want more propertyes, in a same cell you need to create a custom table view cell by subcalssing UITableViewCell. In interface builder you can customize the layout. TUTORIAL: http://adeem.me/blog/2009/05/30/iphone-sdk-tutorial-part-6-creating-custom-uitableviewcell-using-interface-builder-uitableview/

您的问题的具体示例：

.h文件：

 #import <UIKit/UIKit.h>


@interface MyCell : UITableViewCell {
    UIButton * column1;
    UIButton * column2;

    UILabel* column1_label1;
    UILabel* column1_label2;

    UILabel* column2_label1;
    UILabel* column2_label2;
}

@property (nonatomic,retain) UIButton * column1;
@property (nonatomic,retain) UIButton * column2;

@property (nonatomic,retain) UILabel* column1_label1;
@property (nonatomic,retain) UILabel* column1_label2;

@property (nonatomic,retain) UILabel* column2_label1;
@property (nonatomic,retain) UILabel* column2_label2;

@end

.m文件：

#import "MyCell.h"


@implementation MyCell

@synthesize column1,column1_label1,column1_label2,column2,column2_label1,column2_label2;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier

        column1.tag = 1;
        column1.autoresizingMask = 292;

        column1.backgroundColor = [UIColor redColor];
        column1.frame = CGRectMake(0, 0, self.contentView.bounds.size.width/2,  self.contentView.bounds.size.height);


        column1_label1 = [[UILabel alloc] initWithFrame: CGRectMake(column1.bounds.size.width*1/5,

UITableViewController中的用法： / p>

the usage in UITableViewController:

   - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    return 40;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    MyCell * mycell2 = ((MyCell*)cell);
    if (cell == nil) {
        cell = [[[MyCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

        [mycell2.column1 addTarget:self action:@selector(column1Selected:) forControlEvents:UIControlEventTouchUpInside];
        [mycell2.column2 addTarget:self action:@selector(column1Selected:) forControlEvents:UIControlEventTouchUpInside];        
    }

    // Configure the cell...

    mycell2.column1_label1.text = @"column1_label1";
    mycell2.column1_label2.text = @"column1_label2";
    mycell2.column1.tag = indexPath.row*2;
    mycell2.column2_label1.text = @"column2_label1";
    mycell2.column2_label2.text = @"column2_label2";
    mycell2.column2.tag = indexPath.row*2 +1;
    return cell;
}

- (void) column1Selected: (id) sender
{

    UIAlertView *alert = [[ UIAlertView alloc]                          
                          initWithTitle: @" Alert"                          
                          message: [NSString stringWithFormat: @"button %d",((UIButton *) sender).tag]
                          delegate: nil                          
                          cancelButtonTitle: @" OK"                          
                          otherButtonTitles: nil];    
    [alert show] ;
    [alert release];
}
