UITableView 单元格的图像

Question

我的一个应用程序具有图像属性作为 UITableView 中单元格的背景，在测试时，一切都很好，图像和单元格高度与代码中测试的完全一样，但是当它上传时，我尝试下载它通过 iphone 、 ipad 几次，细胞被拉伸，测试时应用的措施完全不同，图像根本不清晰，应用程序包含 2 种尺寸的图像（另一个是视网膜尺寸 @2x）我不知道这是怎么回事或什么我失踪了，我正在使用 XCode 4.2， 请指教，

感谢您的快速回复， 好吧，它的应用内购买包含许多相册，这些相册每个都位于带有图像的uitable view单元格中，下载时，图像会更改并且uitableview会自动刷新，首先将所有图像设置在数组中（ viewDidLoad)

'

UIImage *awwal = [UIImage imageNamed:@"album-01.png"];
    UIImage *teni = [UIImage imageNamed:@"album-02.png"];
    UIImage *telet = [UIImage imageNamed:@"album-03.png"];
    UIImage *rabee = [UIImage imageNamed:@"album-04.png"];
    UIImage *akhir = [UIImage imageNamed:@"album-05.png"];
    UIImage *ba3do = [UIImage imageNamed:@"album-zaman.png"];
    UIImage *aatiha = [UIImage imageNamed:@"album-tarab.png"];
    UIImage *j3ala = [UIImage imageNamed:@"album-monawaa.png"];

    NSMutableArray *images = [[NSMutableArray alloc] initWithObjects: awwal, teni, telet, rabee, akhir, ba3do, aatiha, j3ala, nil];
 self.AlbumsImages = images;
    [images release];'

这就是加载 tableView 的地方

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"CellIdentifier";
   // NSLog(@"%@",AlbumsImages);
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }
     NSUInteger row = [indexPath row];
    NSArray *myPathList = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    NSString *myPath = [myPathList objectAtIndex:0];
    NSString* storagePath = [myPath stringByAppendingPathComponent:@"purchasedAlbums.plist"];
    NSArray* valueList = [[NSArray alloc] initWithContentsOfFile:storagePath];

    UIImage *change1 = [UIImage imageNamed:@"playalbum-06.png"];
    UIImage *change2 = [UIImage imageNamed:@"playalbum-07.png"];
    UIImage *change3 = [UIImage imageNamed:@"playalbum-08.png"];
    UIImage *change4 = [UIImage imageNamed:@"playalbum-09.png"];
    UIImage *change5 = [UIImage imageNamed:@"playalbum-11.png"];
    UIImage *change6 = [UIImage imageNamed:@"playalbum-12.png"];
    UIImage *change7 = [UIImage imageNamed:@"playalbum-10.png"];
    UIImage *change8 = [UIImage imageNamed:@"playalbum-13.png"];

    int i;
    for (i = 0; i <= [AlbumsImages count]; i++) {


    if ([[valueList objectAtIndex:i+1] intValue]) {
        if (i == 0) {
            [AlbumsImages replaceObjectAtIndex:0 withObject:change1];
        }
        if (i == 1) {
            [AlbumsImages replaceObjectAtIndex:1 withObject:change2];
        }
        if (i == 2) {
            [AlbumsImages replaceObjectAtIndex:2 withObject:change3];
        }
        if (i == 3) {
            [AlbumsImages replaceObjectAtIndex:3 withObject:change4];
        }
        if (i == 4) {
            [AlbumsImages replaceObjectAtIndex:4 withObject:change5];
        }
        if (i == 5) {
            [AlbumsImages replaceObjectAtIndex:5 withObject:change6];
        }
        if (i == 6) {
            [AlbumsImages replaceObjectAtIndex:6 withObject:change7];
        }
        if (i == 7) {
            [AlbumsImages replaceObjectAtIndex:7 withObject:change8];
        }

    }
}
        //cell.textLabel.text = [AlbumsView objectAtIndex:row];
    cell.imageView.image = [AlbumsImages objectAtIndex:row];
    cell.tag=row+1;
    return cell;
}

其中change1,2,3.....是下载相册时替换的图片。

只使用名称，而不是扩展名。

UIImage *change1 = [UIImage imageNamed:@"playalbum-06"];
