我在代码中有以下错误?为什么?

线程 1:信号 SIGABRT

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

UITableViewCell *cell1 = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

if (cell1 == nil) {
    cell1 = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];


}

cell1.textLabel.text = [tableData objectAtIndex:indexPath.row];

// create the parent view that will hold header Label

UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(0,0,320,78)] autorelease];

// create image object
UIImage *myImage = [thumbnails objectAtIndex:indexPath.row];

[cell1 addSubview:customView];

// Set up the cell...

// create the imageView with the image in it
UIImageView *imageView = [[UIImageView alloc] initWithImage:myImage];

imageView.frame = CGRectMake(0,0,320,78);
[customView addSubview:imageView];

cell1.imageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
NSLog(@"Hello Last");
return cell1;
}

线路错误:

 UIImageView *imageView = [[UIImageView alloc] initWithImage:myImage];

该怎么办?

看起来您正在某处调用size字符串对象的(不存在的)方法。可能,你的意思length

您的逻辑似乎有问题,您以不同的方式引用同一事物,您正在NSArray通过以下两种方式检索缩略图中的对象:

// Here you assume there is an image in the thumbnails array
UIImage *myImage = [thumbnails objectAtIndex:indexPath.row];

// Here you assume there is a filename in the thumbnails array
cell1.imageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
