如何在iOS中以编程方式在UITableViewCells中添加图像

问题描述

我需要以编程方式在UITableViewCells中添加不同的图像.我怎样才能做到这一点.我正在尝试一些代码.但是图像未显示在UITableViewCells中.这是我的下面的代码.

I need to add different images in UITableViewCells programmatically. How can I do that. I am trying some code. But the images are not displayed in UITableViewCells.This is my code below.

-(void)viewDidLoad
{
    arrImages=[[NSMutableArray alloc]initWithObjects:@"image.png",@"image2.png",@"image3.png",@"image4.png",@"image5.png",@"image6.png",@"image7.png",@"image8.png" nil];
}

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

    static NSString *identifier=@"cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    if (cell == nil) 

    {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"identifier"];

    }

    imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 48, 48)];

    cell.imageView.image = [UIImage imageNamed:[arrImages objectAtIndex:indexPath.row]];

    return cell;
}

推荐答案

在.h文件中创建NSArray的属性

Create a property of NSArray in your .h file

@property NSArray *imgArray;

在您的.m文件中合成

@synthesize imgArray;

将其写在您的viewDidLoad

write this in your viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];


    // Initialize images...
    imgArray = [NSArray arrayWithObjects:@"yourFirstImageName.png", @"yourSecondImageName.png", @"yourThirdImageName.png",....., @"yourSeventhImageName.png", nil];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) 
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];


        UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 48, 48)]; // your cell's height should be greater than 48 for this.
        imgView.tag = 1;
        [cell.contentView addSubview:imgView];
        imgView = nil;

        UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(x, y, width, height)];

        lbl.backgroundColor = [UIColor clearColor];
        [lbl setTag:2];
        [cell.contentView addSubview:lbl];
        lblDisch = nil;
    }

    UIImageView *_imgView = (UIImageView *)[cell.contentView viewWithTag:1];
    _imgView.image = [UIImage imageNamed:[imgArray objectAtIndex:indexPath.row]];

    UILabel *_lbl = (UILabel *)[cell.contentView viewWithTag:2];
    _lbl.text =  [arrFont objectAtIndex:indexPath.row]; // arrFont is your array
    return cell;
}
