是否可以在 UITableViewCell 中添加 UITableView [英] Is it possible to add UITableView within a UITableViewCell

问题描述

听到的只是我想实现的想法，

Hear is just the idea what i am thinking to implement this,

我想实现像页面一样的书，为此我想将 UITableView 和旋转 90 度及其单元格旋转 90 度，现在我想继承 UITableViewCell，现在在这个 tableview 单元格中可以添加 UITableview 所以该用户可以垂直滚动以查看内容，用户也可以水平滚动以转到旋转 tableview 的下一个单元格.我只是在想，有没有更好的方法来实现这一点.

I want to implement book like pages, for this i want to take UITableView and rotated-90 degree and its cell by 90 degree, and now i want to subclass UITableViewCell, now within this tableview cell it is possible to add UITableview so that user can scroll vertically to see the contents and user can also scroll horizontally to go to next cell of rotated tableview. It is just i am thinking, is there any better way to implement this.

推荐答案

是的，我在 UITableView 单元格中添加了 UITableVIew.. :)

yes it is possible, I added the UITableVIew within the UITableView cell .. :)

无需在 xib 文件中添加 tableview 单元格 - 只需将 UITableviewCell 子类化并使用下面的代码，将以编程方式创建单元格.

no need to add tableview cell in xib file - just subclass the UITableviewCell and use the code below, a cell will be created programatically.

//in your main TableView 

#import "ViewController.h"
#import "CustomCell.h"
@interface ViewController ()<UITableViewDataSource , UITableViewDelegate>

@end

@implementation ViewController

- (void)viewDidLoad
 {
   [super viewDidLoad];
   // Do any additional setup after loading the view, typically from a nib.
 }

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

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


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

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
  return 3;
 }

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
   CustomCell *cell = [self.aTV dequeueReusableCellWithIdentifier:@"Cell"];
   if(cell == nil)
   {
     cell = [[[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"]autorelease];
   }

  cell.dataAraay = [NSMutableArray arrayWithObjects:@"subMenu->1",@"subMenu->2",@"subMenu->3",@"subMenu->4",@"subMenu->5", nil];
return  cell;
}

 -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   return 150;
}


//in your custom tableview cell 
//  .m file
#import "CustomCell.h"

@implementation CustomCell 
@synthesize dataAraay; //array to hold submenu data

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
 {
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
    // Initialization code
   self.frame = CGRectMake(0, 0, 300, 50);
   UITableView *subMenuTableView = [[UITableView alloc]initWithFrame:CGRectZero style:UITableViewStylePlain]; //create tableview a

  subMenuTableView.tag = 100;
  subMenuTableView.delegate = self;
  subMenuTableView.dataSource = self;
  [self addSubview:subMenuTableView]; // add it cell
  [subMenuTableView release]; // for without ARC
  }
return self;
}

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

  // Configure the view for the selected state
 }

 -(void)layoutSubviews
 {
   [super layoutSubviews];
   UITableView *subMenuTableView =(UITableView *) [self viewWithTag:100];
   subMenuTableView.frame = CGRectMake(0.2, 0.3, self.bounds.size.width-5,    self.bounds.size.height-5);//set the frames for tableview

}

  //manage datasource and  delegate for submenu tableview
 -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
  {
     return 1;
  }

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

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellID"];
    if(cell == nil)
    {
       cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cellID"]autorelease];
   }
  cell.textLabel.text = [self.dataAraay objectAtIndex:indexPath.row];

  return cell;

}

@end

Swift 版本创建一个单视图项目在storyboard中添加tableview并设置它的datasource和delegate

Swift version Create a single view project add tableview inside storyboard and set up its datasource and delegate

将下面的代码粘贴到 ViewController.swift

  import UIKit

  class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {

  override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a nib.
  }

  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }

  func numberOfSectionsInTableView(tableView: UITableView) -> Int {
      return 3;
  }

  func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
      return 1;
  }

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
      var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as?  CustomCell
      if cell == nil {
         cell = CustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
      }
      cell?.dataArr = ["subMenu->1","subMenu->2","subMenu->3","subMenu->4","subMenu->5"]
      return cell! 
   }

   func  tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
       return 150.0
   }
}

创建一个新文件CustomCell.swift，它是UITableViewCell 的子类，do not select with xib 这个文件没有.xib 文件 table 和它的 cell 将在 objective-c code 中以编程方式创建.

create a new file CustomCell.swift which is the subclass of UITableViewCell and do not select with xib this file is without .xib file table and its cell will be created programatically as in objective-c code.

将下面的代码粘贴到 CustomCell.swift

  import UIKit

  class CustomCell: UITableViewCell,UITableViewDataSource,UITableViewDelegate {

  var dataArr:[String] = []
  var subMenuTable:UITableView?
  override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
      super.init(style: style , reuseIdentifier: reuseIdentifier)
      setUpTable()
  }

  required init(coder aDecoder: NSCoder) {
      fatalError("init(coder:) has not been implemented")
      setUpTable()
  }

  override func awakeFromNib() {
      super.awakeFromNib()
      // Initialization code
      setUpTable()
  }

  func setUpTable(){
      subMenuTable = UITableView(frame: CGRectZero, style:UITableViewStyle.Plain)
      subMenuTable?.delegate = self
      subMenuTable?.dataSource = self
      self.addSubview(subMenuTable!)
  }

  override func layoutSubviews() {
      super.layoutSubviews()
      subMenuTable?.frame = CGRectMake(0.2, 0.3, self.bounds.size.width-5, self.bounds.size.height-5)
  }

  override func setSelected(selected: Bool, animated: Bool) {
      super.setSelected(selected, animated: animated)
      // Configure the view for the selected state
  }

  func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
      return dataArr.count
  }

  func numberOfSectionsInTableView(tableView: UITableView) -> Int {
      return 1
  }

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cellID")

    if cell == nil {
        cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cellID")
    }

    cell?.textLabel?.text = dataArr[indexPath.row]

    return cell!
  }
}
