Question

我正在使用带有自定义单元格的分组UITableview。我的tableview包含两个部分。我需要更改第0部分中的两行textfield框架。如何可能？请帮助我。通过我的代码

customcell.m

-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code

        self.textfiled1 = [[UITextField alloc]init];
        self.textfiled1.returnKeyType = UIReturnKeyNext;
        textfiled1.clearButtonMode = UITextFieldViewModeWhileEditing;

        [self.contentView addSubview:self.textfiled1];

    }
    return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];
}
-(void)layoutSubviews{

    [super layoutSubviews];
    self.textfiled1.frame = CGRectMake(50, 3, 250,40);
}

#pragma Tableview Delegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath
{
    if(indexPath.section == 0)
    {
        static NSString *CellIdentifier = @"Cell";
        customcell*cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

        if (cell == nil) {
            cell = [[customcell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
            cell.selectionStyle = UITableViewCellSeparatorStyleNone;
        }
        cell.textfiled1.delegate = self;
        if (indexPath.row==0) {

            cell.textfiled1.frame = CGRectMake(50,3,180,40);//Change textfield frame

            cell.separatorInset = UIEdgeInsetsMake(0, 50, 0, 100);

        }
        else if(indexPath.row==1)
        {
            cell.textfiled1.frame = CGRectMake(50,3,180,40);//Change textfield frame

        }
        else if(indexPath.row==2)
        {

            cell.textfiled1.keyboardType = UIKeyboardTypePhonePad;

        }
        else if(indexPath.row==3)
        {

        }
        return cell;
    }
    else if(indexPath.section == 1)
    {
        static NSString *CellIdentifier1 = @"Cell1";
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];

        if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1];
        }
        cell.textLabel.text = @“Section1";
        return cell;
    }

}

Answer 1

而不是这样做一个属性，以便你可以设置指定的帧，你想听到代码，在控制器中你需要为每个单元格设置框架，看看下面的代码

 //CustomCell.h file

 @interface CustomCell : UITableViewCell
 @property(nonatomic,assign) CGRect  TextFieldFrame;//put this to change the frame
 @property (nonatomic,retain)UITextField *textfiled1;
 @end

 //in CustomCell.m file
 #import "CustomCell.h"

 @implementation CustomCell
 @synthesize  TextFieldFrame;//sysnthesise
 @synthesize textfiled1;

 - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
 {
   self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
   if (self) {
            self.textfiled1 = [[UITextField alloc]init];
            self.textfiled1.backgroundColor = [UIColor greenColor];
            self.textfiled1.returnKeyType = UIReturnKeyNext;
            textfiled1.clearButtonMode = UITextFieldViewModeWhileEditing;
            [self.contentView addSubview:self.textfiled1];
      }
     return self;
 }


 -(void)layoutSubviews{

   [super layoutSubviews];
    self.textfiled1.frame = CGRectMake(self.bounds.origin.x + self.TextFieldFrame.origin.x, self.bounds.origin.y + self.TextFieldFrame.origin.y, self.TextFieldFrame.size.width, self.TextFieldFrame.size.height);
   //  self.textfiled1.frame = CGRectMake(50, 3, 250,40);//hear u are setting the contant frame thats wy frames are not changed
    }

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

     // Configure the view for the selected state
    }


  //in ViewController.m file
 #import "ViewController.h"
 #import "CustomCell.h"

 @interface ViewController ()<UITableViewDataSource,UITableViewDelegate>

 @end

 @implementation ViewController


  - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
 {
    return 2;
 }

  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
      return 2;
 }


  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
     if(indexPath.section == 0)
    {
      static NSString *CellIdentifier = @"Cell";
      CustomCell*cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

        if (cell == nil) {
        cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSeparatorStyleNone;
       }
       cell.textfiled1.delegate = self;
       if (indexPath.row==0) {

       cell.TextFieldFrame = CGRectMake(50,3,180,40);//Change textfield frame, u can set the frame for each cell hear

        cell.separatorInset = UIEdgeInsetsMake(0, 50, 0, 100);

       }
      else if(indexPath.row==1)
       {
          cell.TextFieldFrame = CGRectMake(50,3,180,40);//Change textfield frame, heare also

       }
       return cell;
  }
  else if (indexPath.section == 1)
  {
     static NSString *CellIdentifier = @"Cell_2";
     CustomCell*cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

     if (cell == nil) {
        cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSeparatorStyleNone;
       }
      cell.textfiled1.delegate = self;
      if(indexPath.row==0)
     {

         cell.textfiled1.keyboardType = UIKeyboardTypePhonePad;
        cell.TextFieldFrame = CGRectMake(80, 3, 180, 40); //for other cells default frame u need to set it heare

     }
      else if(indexPath.row==1)
     {
         cell.textfiled1.keyboardType = UIKeyboardTypePhonePad;
         cell.TextFieldFrame = CGRectMake(80, 3, 180, 40);

     }
     return cell;

 }
  else
      return nil;

}

  - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
  return 50;
}

创建自定义表视图单元初始值设定项并传递indexpath。所以现在在tableview单元格中，你知道行，根据行号进行更改

在iOS7中更改自定义UITableviewCell上的UITextfield宽度
