Question

我的表格视图使用自定义类来创建单元格

MyCustomCell.h

#import <UIKit/UIKit.h>

@interface MyCustomCell : UITableViewCell

@end

MyCustomCell.m

#import "MyCustomCell.h"
#import <QuartzCore/QuartzCore.h>


@implementation MyCustomCell

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

    }
    return self;
}

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

    self.selectionStyle = UITableViewCellSelectionStyleBlue;

    // Configure the view for the selected state
}

- (void)layoutSubviews
{
    [super layoutSubviews];
    self.imageView.frame = CGRectMake(5,4,80,80);
    self.imageView.layer.masksToBounds = YES;
    self.imageView.layer.cornerRadius = 5.0f;
    self.imageView.contentMode = UIViewContentModeScaleAspectFill;
    float imgWidth =  self.imageView.image.size.width;
    if(imgWidth > 0)
    {
        self.textLabel.frame = CGRectMake(110,2,170,25);
        self.detailTextLabel.frame = CGRectMake(110,18,200,25);
        self.detailTextLabel.font = [UIFont boldSystemFontOfSize:12];
        self.detailTextLabel.alpha = 0.0;
        self.textLabel.font = [UIFont boldSystemFontOfSize:12];
        self.textLabel.textColor = [UIColor colorWithRed:.2314 green:.3490 blue:.5961 alpha:1.0];


    }
}

@end

并且像这样使用它：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";


    MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {


        cell = [[MyCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        //cell.accessoryType = UITableViewCellAccessoryCheckmark;



    }

    CGFloat screenHeight = [UIScreen mainScreen].bounds.size.height;

    if ([UIScreen mainScreen].scale == 2.f && screenHeight == 568.0f)
    {
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn setBackgroundImage:[UIImage imageNamed:@"select2x.png"] forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(SelectButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
    btn.frame = CGRectMake(110, 25, 63, 32);
        //btn.tag = indexPath.row;

        viewProfile = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        viewProfile.frame = CGRectMake(190, 25, 93, 32);
        //[viewProfile setTitle:@"View Profile" forState:UIControlStateNormal];
        [viewProfile setBackgroundImage:[UIImage imageNamed:@"viewProfile@2x.png"] forState:UIControlStateNormal];
        [viewProfile addTarget:self action:@selector(viewProfileTapped:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:viewProfile];

    [cell.contentView addSubview:btn];

    }

    else
    {

        UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        [btn setBackgroundImage:[UIImage imageNamed:@"select.png"] forState:UIControlStateNormal];
        [btn addTarget:self action:@selector(SelectButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
        btn.frame = CGRectMake(110, 25, 63, 32);
        //btn.tag = indexPath.row;

        viewProfile = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        viewProfile.frame = CGRectMake(190, 25, 93, 32);
        //[viewProfile setTitle:@"View Profile" forState:UIControlStateNormal];
        [viewProfile setBackgroundImage:[UIImage imageNamed:@"viewProfile.png"] forState:UIControlStateNormal];
        [viewProfile addTarget:self action:@selector(viewProfileTapped:) forControlEvents:UIControlEventTouchUpInside];
        [cell.contentView addSubview:viewProfile];

        [cell.contentView addSubview:btn];


       }

    return cell;

}

现在每个单元格都包含两个执行动作的按钮（我不会对单击按钮进行操作，但按钮按下），如上所示

现在我想要的是当用户点击特定单元格中的按钮（比如选择按钮）时，该特定单元格应该突出显示或着色或着色，当用户点击另一个单元格中的按钮时，该单元格应该突出显示使前一个单元格没有突出显示。我已经尝试将前一个和下一个索引路径存储在2个不同的变量中，但是无法对它们进行处理以实现我想要的。

- (void)SelectButtonTapped:(UIButton *)button
{


    UITableViewCell *cell = (UITableViewCell *)button.superview.superview;

    NSIndexPath *indexPath = [homeTable indexPathForCell:cell];

    // UITableViewCell *cell1 = [homeTable cellForRowAtIndexPath:indexPath];

    //currentSelection = indexPath.row;

    //MyCustomCell *cell1 = (MyCustomCell *)[homeTable cellForRowAtIndexPath:indexPath];

    [[homeTable delegate]tableView:homeTable didSelectRowAtIndexPath:indexPath];

     //MyCustomCell *cell1 = (MyCustomCell *)[homeTable cellForRowAtIndexPath:indexPath];

    /*if(currentSelection == 0)
    {
         [cell1 setSelected:YES animated:YES];
        currentSelection++;
    }
    else
    {
         [cell1 setSelected:YES  animated:YES];

    }*/
   // NSIndexPath *indexPath1 = [homeTable indexPathForCell:cell];

    NSLog(@"current===>%d",currentSelection);



    //[cell1 setSelected:NO animated:YES];

    //if(currentSelection == indexPath)




    //UIButton *clickButton = (UIButton *)sender;
    // NSIndexPath *indexPathHighlight = [NSIndexPath indexPathForRow:button.tag inSection:0];

    //button.tag = indexPathHighlight.row;





    //UITableViewCell *newCell = [homeTable cellForRowAtIndexPath:indexPathHighlight];


    //if(newCell.selected == NO)
    //{
    //[newCell setSelected:YES animated:YES];
     //   [newCell setBackgroundColor:[UIColor lightGrayColor]];
    //}
    //else
   // {
        //[newCell setSelected:NO animated:YES];
        //[newCell setBackgroundColor:[UIColor colorWithRed:232.0f/255.0f green:237.0f/255.0f blue:240.0f/255.0f alpha:1.0f]];
    //}
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    MyCustomCell *cell1 = (MyCustomCell *)[homeTable cellForRowAtIndexPath:indexPath];

    cell1.selectionStyle= UITableViewCellSelectionStyleBlue;

}

你可以看看我凌乱的按钮动作方法。我尝试了很多选择但没有成功。请帮忙。

Answer 1

取消注释该行：

btn.tag = indexPath.row+1000;

还将单元格选择样式更改为

[cell setSelectionStyle:UITableViewCellSelectionStyleBlue];

创建时。

在SelectButtonTapped方法中：

- (void)SelectButtonTapped:(UIButton *)button
{
  int buttonIndex = button.tag;

  for (int row = 0; row<numberOfRows; row++)
  {
    NSIndexPath indexPathHighlight = [NSIndexPath indexPathForRow:row inSection:0];

    UITableViewCell *newCell = [yourTable cellForRowAtIndexPath:indexPathHighlight];

    if (row == buttonIndex - 1000)
    {
        [newCell setSelected:YES animated:YES];
    }
    else
    {
        [newCell setSelected:NO animated:YES];
    }
  }
}

Answer 2

让我们认为您的表只有一个部分，而按钮的标记是相应单元格的行号。

在按钮操作

中

int rownumber = button.tag;
//print the rownumber and see if you are getting the correct value
UITableViewCell *cell = [tablename cellForRowAtIndexPath:[NSIndexPath     
indexPathForRow:rownumber inSection:0]];

[cell setHighlighted:YES];

Answer 3

试试这个 -

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    MyCustomCell *cell1 = (MyCustomCell *)[homeTable cellForRowAtIndexPath:indexPath];
    cell1.selectionStyle= UITableViewCellSelectionStyleBlue;
}
