我无法设置自定义表视图和动态行组

Question

我想像这个自定义的tableview一样实现。

有没有人可以教我如何实现这个tableview方法？

早上＆＃34; ，＆＃34;下午＆＃34;，＆＃34;晚上＆＃34;标签必须放左。

然后标签后面有许多不同的按钮。

如果一行有超过3个按钮。它会放下一行（行）（如下面的照片＆＃34;下午＆＃34;）。

我知道日期是使用标题标题。然后早上，下午，夜间使用了部分。

但我不知道如何实施＆＃34;早晨＆＃34;，＆＃34;下午＆＃34; ，＆＃34;晚上＆＃34;标签放左，然后按钮放右。 关键问题是我不能设置下午（早上或晚上）小组。

有没有人可以给我一些提示，或者一些教程如何动态设置（下午，早上或晚上）小组？

非常感谢!!!!! ＆lt;（_ _）＆gt;

对不起迟到的回答但如果按钮数超过3，则不需要使用不同的行，这将是tableview的复杂管理，相反，为什么不使用不同高度的唱行与所有按钮可以放在tableview单元格内的适当位置。

看下面的代码你可以在单独的项目中尝试它，因为自定义单元格不使用默认单元格“UITableViewCell”而是子类它，你可以轻松管理单元格内容（我建议）

在子类的.m文件中（我拿了一个日期字符串，数组包含按钮标题），这是你的时间

  #import <UIKit/UIKit.h>

  //you need to use the custom cell

  @interface CustomCell : UITableViewCell //subclass the UITableViewCell for complete customization

  @property (nonatomic, retain) NSString *titleString;//string for mrng or eve or nyt
  @property (nonatomic, retain) NSArray *buttons;//for your buttons 
  @end

<。>文件中的

 #import "CustomCell.h"

 @implementation CustomCell
 //synthesize them
 @synthesize titleString;
 @synthesize buttons;

 //custom setters method this will handle all the buttons initilizations
- (void)setButtons:(NSArray *)inButtons
{
   if(inButtons != buttons)
   {
     buttons = inButtons;
    // [buttons release]; //ARC give's error in this part so comment it
    // [inButtons retain];
     if(buttons)
    {
        [self createButtonForThecell];//call your helper to add the buttons to cell
    }
   }
}

 - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
 {
  self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
  if (self) {
    // Initialization code
    //put a label in the cell
    UILabel *titleLabel = [[UILabel alloc]init];
    titleLabel.tag = 1000;//to get it in the layout subviews
    [self addSubview:titleLabel];//add it to cell
  }
  return self;
}

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

 // Configure the view for the selected state
}

 - (void)createButtonForThecell
  {
   //at this movement u get the buttons array contains the string (buttons) to be placed in the cell
  int xValue,Yvalue;
  xValue = 63;
  Yvalue = 0;
  int i = 1;
  NSLog(@"buttons->%d",[self.buttons count]);
  for(int k = 0 ;k< [self.buttons count];k++)//loop throug the button
   {
     //you need 3 for each row starts after 90 from x-axis

      UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(xValue , 2 + Yvalue, 65, 35)];
      if(k == (3 * i) || (k % 3) == 2)
      {
          i = i + 1;
          Yvalue += (35 + 5);
          xValue = 63;
      }
      else
      {   
          xValue += (63 + 5);
      }
       [button addTarget:self action:@selector(whenEventButtonClicked) forControlEvents:UIControlEventTouchUpInside];
      [button setTitle:[self.buttons objectAtIndex:k] forState:UIControlStateNormal];
      [button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
      [button setTag:k];//setting the tag to index it will become use for the acces of which button tapped
      //finally add it to cell
      [self addSubview:button];

     }

  } 

 - (void)whenEventButtonClicked
 {
     //hear put a delegate to controller for further processing of the event
     NSLog(@"button clicked");
 }

 - (void)layoutSubviews
 {
    [super layoutSubviews];
    //in the this always set the frme
     UILabel *label = (UILabel *)[self viewWithTag:1000];
    if(label)
    {
       label.frame = CGRectMake(2, 3, 55, 35);//your label in the left side
       label.text = self.titleString;//set the string
      label.textColor = [UIColor greenColor];//set the color for your label
    } 
 }


@end

在控制器的.m文件中 我拿了一个包含如下词典的数组

  - (void)viewDidLoad
  {
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
    present = NO;
    listResultDataAry  = [[NSMutableArray alloc]init];
     NSMutableDictionary *tempDict = [[NSMutableDictionary alloc]init];
    [tempDict setObject:@"Mrng" forKey:@"Date"];
    [tempDict setObject:[[NSArray alloc]initWithObjects: @"Button1",@"Button2",@"Button3",@"button4",@"button5", nil] forKey:@"time"];
    [listResultDataAry addObject:tempDict];

     NSMutableDictionary *tempDict1 = [[NSMutableDictionary alloc]init];
    [tempDict1 setObject:@"Eveng" forKey:@"Date"];
    [tempDict1 setObject:[NSArray arrayWithObjects: @"Button1",@"Button2",@"Button3", nil] forKey:@"time"];
    [listResultDataAry addObject:tempDict1];

    NSMutableDictionary *tempDict2 = [[NSMutableDictionary alloc]init];
    [tempDict2 setObject:@"Nyt" forKey:@"Date"];
    [tempDict2 setObject:[[NSArray alloc]initWithObjects: @"Button1",@"Button2",@"Button3",@"Button4",@"button5",@"button6",@"button7",@"button 8", nil] forKey:@"time"];
    [listResultDataAry addObject:tempDict2];

  }

表视图中的

委托方法

   - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
   {
       return 1;//return how many sections are there
   }

  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
  {
     return [listResultDataAry count];//return  u hav for mrng,eveng,nyt for the more numbers u can resize the tableview cell
  }

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
     CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
     if(cell == nil)
     {
     cell = [[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
     }
     NSMutableDictionary *tempDict = [listResultDataAry objectAtIndex:indexPath.row];
     NSLog(@"IndexPath.row = %d",indexPath.row);

     cell.titleString = [tempDict objectForKey:@"Date"];//set the date for your label
      cell.buttons = [tempDict objectForKey:@"time"];


    return cell;
  }

  - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
 {
    //hear u need to cumpute the height for each cell
     NSMutableDictionary *tempDict = [listResultDataAry objectAtIndex:indexPath.row];
    NSArray *tempArray = [tempDict objectForKey:@"time"];
     CGFloat height =   [self computeHeight:tempArray];
    return height;

 }
 - (CGFloat)computeHeight:(NSArray *)array
 {
    CGFloat height = 40;              //0 1 2
   int i = 1;                                 //3 4 5
   for(int k = 0; k< [array count];k++)
   {
      if(k == (3 * i))
      {
         height = height + 40;
         i = i + 1;
     }
  }
  return height;
}

希望这有助于你......：）

    return [listResultDataAry count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:        (NSInteger)section{
    // 3 is morning , afternoon , night.  But I think it will dynamic caculate to         implement every label group.
    return 3;
}

   //Calculate height by your dataSource
   return PerLineHeight * ((BtnCount-1)/3+1)
}

{
    //Create a UILabel and set date by your dataSource
    return dateLabel;
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    //Create a UILabel and set date by your dataSource
    return dateLabel;
}
