UILabels
セルの contentView プロパティを使用してテーブル ビュー セルに表示されないという問題があります。セルにUIImageUILabels
を追加する前に表示されていました。セルにテキストを追加したいと思い、 cell.contenView を使用して、必要な場所に UILAbels を配置できるようにしました。
これを手伝ってくれてありがとう。
ここに私のコードがあります:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * cellReuseIdentifier = @"cellReuseIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellReuseIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellReuseIdentifier];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 2, 320, 30)];
titleLabel.tag = 234234;
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor whiteColor];
[titleLabel setFont:[UIFont fontWithName:@"DIN" size:24]];
titleLabel.layer.shadowColor = [[UIColor whiteColor] CGColor];
titleLabel.layer.shadowOpacity = 0.7;
titleLabel.layer.shouldRasterize=YES;
[cell.contentView addSubview:titleLabel];
UILabel *detailLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 160, cell.bounds.size.width, 30)];
detailLabel.tag = 345345;
detailLabel.backgroundColor = [UIColor clearColor];
detailLabel.textColor = [UIColor whiteColor];
[detailLabel setFont:[UIFont fontWithName:@"DIN" size:18]];
detailLabel.layer.shadowColor = [[UIColor whiteColor] CGColor];
detailLabel.layer.shadowOpacity = 0.7;
detailLabel.layer.shouldRasterize=YES;
[cell.contentView addSubview:detailLabel];
}
UILabel *titleLabel = (UILabel *)[cell viewWithTag:234234];
titleLabel.text = (NSString *)[[publicDataArray objectAtIndex:indexPath.row] objectForKey:@"title"];
UILabel *detailLabel = (UILabel *)[cell viewWithTag:345345];
detailLabel.text = (NSString *)[[publicDataArray objectAtIndex:indexPath.row] objectForKey:@"description"];
NSString *imageUrlString = [NSString stringWithFormat:@"%@", [[publicDataArray objectAtIndex:indexPath.row] objectForKey:@"image"]];
UIImage *cachedImage = [self.imageCache objectForKey:imageUrlString];
if (cachedImage)
{
cell.imageView.image = cachedImage;
}
else
{
cell.imageView.image = [UIImage imageNamed:@"rest.jpg"]; // initialize the image with blank image as a placeholder
// download in the image in the background
[self.imageDownloadingQueue addOperationWithBlock:^{
NSURL *imageUrl = [NSURL URLWithString:imageUrlString];
NSData *imageData = [NSData dataWithContentsOfURL:imageUrl];
UIImage *image = nil;
if (imageData)
image = [UIImage imageWithData:imageData];
if (image)
{
[self.imageCache setObject:image forKey:imageUrlString]; // add the image to your cache
// finally, update the user interface in the main queue
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
// make sure the cell is still visible
UITableViewCell *updateCell = [tableView cellForRowAtIndexPath:indexPath];
if (updateCell)
cell.imageView.image = image;
}];
}
}];
}
return cell;
}
cell.textLabel.text = [[publicDataArray objectAtIndex:indexPath.row] objectForKey:@"title"];
また、 contentView を使用する代わりに追加 すると、セル テキストが右側に表示されます。
