当我选择它时,我想在表格视图中展开一个单元格。最初应该如下所示:
在扩展时,它应该提供更多这样的细节:
这就是我最初创建单元格的方式:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * MyIdentifier = @"MyIdentifier";
UITableViewCell * cell = [self.table dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:MyIdentifier] autorelease];
cell.textLabel.frame = CGRectMake(0, 0, cell.textLabel.frame.size.width,
cell.textLabel.frame.size.height);
}
id key = [[articles allKeys] objectAtIndex:indexPath.section];
cell.textLabel.text =@"TitleTitleTitle";
cell.detailTextLabel.text=@"DeatailDeatailDeatailDeatailDeatailDeatailDeatailDeatailDeatai";
return cell;
}
答案 0 :(得分:1)
我在github
发布了示例代码您的tabelView:cellForRowAtIndexPath:
看起来像这样。
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * MyIdentifier = @"MyIdentifier";
UITableViewCell * cell = [self.table dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:MyIdentifier] autorelease];
cell.textLabel.frame = CGRectMake(0, 0, cell.textLabel.frame.size.width,
cell.textLabel.frame.size.height);
}
id key = [[articles allKeys] objectAtIndex:indexPath.section];
cell.textLabel.text =@"TitleTitleTitle";
cell.detailTextLabel.text=@"DeatailDeatailDeatailDeatailDeatailDeatailDeatailDeatailDeatai";
//SEE MY NOTE BELOW
if([indexPath isEqual:selectedIndexPath]){
cell.textLabel.numberOfLines=0;
cell.detailTextLabel.numberOfLines=0;
CGSize constraintSize;
constraintSize.width = cell.textLabel.frame.size.width;
constraintSize.height = MAXFLOAT;
cell.textLabel.frame = [cell.textLabel.text sizeWithFont:cell.textLabel.font constrainedToSize:constraintSize];
constraintSize.width = cell.detailTextLabel.frame.size.width;
constraintSize.height = MAXFLOAT;
cell.detailTextLabel.frame = [cell.detailTextLabel.text sizeWithFont:cell.detailTextLabel.font constrainedToSize:constraintSize];
} else {
cell.textLabel.numberOfLines=1;
cell.detailTextLabel.numberOfLines=1;
}
return cell;
}

您还需要tableView:heightForRowAtIndexPath:
中动态单元格的高度,因此您应该将大小调整部分重构为辅助方法,将2个标签的大小和单元格的高度写入ivars,调用方法从tableView:heightForRowAtIndexPath:
开始,使用此处的单元格高度和tabelView:cellForRowAtIndexPath:
