Question

我在单元格中获取此类数据。如何设置单元格的文本和详细信息文本，以便两个文本都以可读格式显示。

-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
    }

    cell.textLabel.font=[UIFont fontWithName: @"Arial" size: 14.0 ];

    cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;

    [cell setBackgroundColor:[UIColor whiteColor]];

    UILabel *idLabel = (UILabel*)[cell.contentView viewWithTag:201];
    if(!idLabel)
    {
        idLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 50)];
        cell.textLabel.textColor = [UIColor blackColor];
        idLabel.tag = 201;
        [cell.contentView addSubview:idLabel];

    }
    idLabel.text = [arrayFiltered objectAtIndex:indexPath.row];

    cell.textLabel.text = [idArray objectAtIndex:indexPath.row];
    cell.textLabel.textColor = [UIColor grayColor];

    cell.detailTextLabel.text = [descArray objectAtIndex:indexPath.row];
    cell.detailTextLabel.textColor = [UIColor blueColor];
    cell.detailTextLabel.numberOfLines = 2;
    cell.detailTextLabel.adjustsFontSizeToFitWidth = YES;



    return cell;
}

我写的代码在上面。请帮帮我。

我们有3个或更多选项来实现这一点。我会逐步解释您的过程我创建tableView并挂钩。

ViewController.h

#import <UIKit/UIKit.h>
@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
@property (strong, nonatomic) IBOutlet UITableView *tblView;
@end

ViewController.m

#import "ViewController.h"
#import "CustomCell.h"  // For CustomCell using,we have to import.
@interface ViewController ()
{
  NSMutableArray *idArray;
  NSMutableArray *descArray;
}

@end

@implementation ViewController

在viewDidLoad方法中，我将对象添加到id desc数组。

- (void)viewDidLoad 
{
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  idArray = [[NSMutableArray alloc]initWithObjects:@"INOX",@"Sathyam",@"PVR",@"IMAX",nil];
  descArray = [[NSMutableArray alloc]initWithObjects:@"INOX currently operates 107 multiplexes and 420 screens in 57 cities across India",@"SPI Cinemas is an Indian multiplex chain and film production company owned by the SPI Group, headquartered in Chennai.",@"The IMAX cinema process increases the image resolution by using larger film frame;",@"PVR Cinemas is the largest and the most premium film entertainment company in India.",nil];
}

下面的tableView数据源方法

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
   return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   return idArray.count;
}

现在我有3个选项来实现您的需求。但所有这些都是在cellForRowAtIndexPath方法中实现的。

第一个选项：UITableViewCellStyleDefault - 如果你使用它，你可以在下面的cellForRowAtIndexPath中实现代码

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  static NSString *strCell = @"cell";
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:strCell];
  if(cell==nil)
  {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strCell];
  }

  UILabel *idLabel = [[UILabel alloc]init];
  idLabel.frame = CGRectMake(15, 13, 168, 24);
  idLabel.tag = indexPath.row;
  idLabel.numberOfLines = 1;
  idLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:18];
  idLabel.textAlignment = NSTextAlignmentLeft;
  idLabel.textColor = [UIColor blackColor];
  idLabel.text = [NSString stringWithFormat:@"%@",[idArray objectAtIndex:indexPath.row]];
  [cell.contentView addSubview:idLabel];

  UILabel *descLabel = [[UILabel alloc]init];
  descLabel.frame = CGRectMake(15, 47, 348, 34);
  descLabel.tag = indexPath.row;
  descLabel.numberOfLines = 2;
  descLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:12];
  descLabel.textAlignment = NSTextAlignmentLeft;
  descLabel.textColor = [UIColor blueColor];
  descLabel.text = [NSString stringWithFormat:@"%@",[descArray objectAtIndex:indexPath.row]];
  [cell.contentView addSubview:descLabel];

  return cell;
}

第二个选项：UITableViewCellStyleSubtitle - 如果你使用它，你可以在cellForRowAtIndexPath中实现代码，如下所示

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  static NSString *strCell = @"cell";
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:strCell];
  if(cell==nil)
  {
     cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:strCell];
  }

  cell.textLabel.text = [NSString stringWithFormat:@"%@",[idArray objectAtIndex:indexPath.row]];
  cell.textLabel.tag = indexPath.row;
  cell.textLabel.numberOfLines = 1;
  cell.textLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:18];
  cell.textLabel.textAlignment = NSTextAlignmentLeft;
  cell.textLabel.textColor = [UIColor blackColor];

  cell.detailTextLabel.text = [NSString stringWithFormat:@"%@",[descArray objectAtIndex:indexPath.row]];
  cell.detailTextLabel.tag = indexPath.row;
  cell.detailTextLabel.numberOfLines = 2;
  cell.detailTextLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:12];
  cell.detailTextLabel.textAlignment = NSTextAlignmentLeft;
  cell.detailTextLabel.textColor = [UIColor blueColor];

  return cell;
}

第三种选择：自定义单元格 - 如果使用自定义单元格，则必须先导入CustomCell.h。之后，您必须在cellForRowAtIndexPath方法中执行以下操作

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
   CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:@"cell"];
   NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
   if(cell == nil){
     cell = nib[0];
   }
   cell.idLabel.text = [NSString stringWithFormat:@"%@",[idArray objectAtIndex:indexPath.row]];
   cell.idLabel.tag = indexPath.row;
   cell.idLabel.numberOfLines = 1;
   cell.idLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:18];
   cell.idLabel.textAlignment = NSTextAlignmentLeft;
   cell.idLabel.textColor = [UIColor blackColor];

   cell.descLabel.text = [NSString stringWithFormat:@"%@",[descArray objectAtIndex:indexPath.row]];
   cell.descLabel.tag = indexPath.row;
   cell.descLabel.numberOfLines = 2;
   cell.descLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:12];
   cell.descLabel.textAlignment = NSTextAlignmentLeft;
   cell.descLabel.textColor = [UIColor blueColor];

   return cell;
 }

我附上了自定义单元格的屏幕截图。它显示了我在那里所做的事情。

SNAPCHAT 1：idLabel

SNAPCHAT 2：descLabel

您可以使用heightForRowAtIndexPath方法设置行高。它是UITableViewDelegate方法

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
  return 90;
}

注意：通常我设置标签的标签是idLabel.tag = indexPath.row.Acording 根据您的要求在此处设置标记。

我为你创建并制作了示例应用程序。我已经成功完成了。

Answer 2

使用单元格textLable和detailTextLable显示您的数据，如下面的代码 -

cell.textLabel.text=@"your text";


cell.detailTextLabel.text=@"your text";

Answer 3

idLabel会覆盖textlabel的位置。如果你想把id放在文本之前，你可以将字符串和文本标签放在一起。其他使用不要使用textlabel和detail textlabel，创建自己的所有三个标签并使用Frame值正确对齐。

Answer 4

检查单元格的高度，并根据单元格文本和标签行数进行计算。并移动你的字体，背景颜色，单元格内的标签的换行设置== nil。

编辑：要调整三个标签，您需要自定义单元格或如果您可以将其与文本标签连接。这一切都取决于您的要求。
