tableview scrollview

Question

我想製作一個UITableView，它有很多列，所以整個單元格不能顯示所有數據，第一列顯示標題，這一行不能平滑移動，但其他行可以平滑移動。 我嘗試添加UITableView到UIScrollView，但失敗

有沒有什麼辦法可以達到這個要求？

您需要自定義TableViewCell才能正確實現此目的。

編輯： 一個簡單的例子：在實現代碼如下

#import <UIKit/UIKit.h> 

@interface MultiColumnTableViewCell : UITableViewCell 
{ 
    UIButton *leftButton; 
    UIButton *middleButton; 
    UIButton *rightButton; 
} 

@property (nonatomic,retain) UIButton *leftButton; 
@property (nonatomic,retain) UIButton *middleButton; 
@property (nonatomic,retain) UIButton *rightButton; 

@end 


#import "MultiColumnTableViewCell.h" 

    @implementation MultiColumnTableViewCell 

    @synthesize leftButton; 
    @synthesize middleButton; 
    @synthesize rightButton; 

    - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier 
    { 
     self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; 
     if (self) { 
      // Initialization code 
      leftButton = [[UIButton alloc] init]; 
      [leftButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
      leftButton.titleLabel.textAlignment = UITextAlignmentCenter; 
      leftButton.titleLabel.font = [UIFont systemFontOfSize:15.0]; 
      leftButton.titleLabel.numberOfLines = 2; 

      middleButton = [[UIButton alloc] init]; 
      [middleButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
      middleButton.titleLabel.textAlignment = UITextAlignmentCenter; 
      middleButton.titleLabel.font = [UIFont systemFontOfSize:15.0]; 
      middleButton.titleLabel.numberOfLines = 2; 

      rightButton = [[UIButton alloc] init]; 
      [rightButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
      rightButton.titleLabel.textAlignment = UITextAlignmentCenter; 
      rightButton.titleLabel.font = [UIFont systemFontOfSize:15.0]; 
      rightButton.titleLabel.numberOfLines = 2; 
     } 
     return self; 
    } 

    - (void)setSelected:(BOOL)selected animated:(BOOL)animated 
    { 
     [super setSelected:selected animated:animated]; 

     // Configure the view for the selected state 
    } 

    @end 

快速用法：

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

    MultiColumnTableViewCell *cell = (MultiColumnTableViewCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[MultiColumnTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
    } 

    // Set up the cell... 
    float tableviewWidth = self.myTableView.frame.size.width/3; 
    int irow = indexPath.row; 

    NSString *cellValue = myString; 

    cell.leftButton.frame = CGRectMake(0, 0, tableviewWidth, 64.0); 
    cell.leftButton.tag = someTag; 
    [cell.leftButton setTitle:cellValue forState:UIControlStateNormal]; 
    [cell.leftButton addTarget:self action:@selector(someAction:) forControlEvents:UIControlEventTouchUpInside]; 
    [cell addSubview:cell.leftButton]; 

    cellValue = someOtherString; 
    cell.middleButton.frame = CGRectMake(tableviewWidth, 0, tableviewWidth, 64.0); 
    cell.middleButton.tag = someOtherTag; 
    [cell.middleButton setTitle:cellValue forState:UIControlStateNormal]; 
    [cell.middleButton addTarget:self action:@selector(someOtherAction:) forControlEvents:UIControlEventTouchUpInside]; 
    [cell addSubview:cell.middleButton]; 

    cellValue = yetAnotherString 
    cell.rightButton.frame = CGRectMake(tableviewWidth*2, 0, tableviewWidth, 64.0); 
    cell.rightButton.tag = yetAnotherTag; 
    [cell.rightButton setTitle:cellValue forState:UIControlStateNormal]; 
    [cell.rightButton addTarget:self action:@selector(yetAnotherAction:) forControlEvents:UIControlEventTouchUpInside]; 
    [cell addSubview:cell.rightButton]; 

    return cell; 
}
