我的表格中有两列:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSUInteger const kLeftLabel =100;
static NSUInteger const kRightLabel=101;
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
CGRect leftF = CGRectMake(10, 5, 100, 30);
CGRect rightF = CGRectMake(120, 5, 100, 30);
left = [[[UILabel alloc] initWithFrame:leftF] autorelease];
left.tag = kLeftLabel; // assumming #define kLeftLabel 100
[cell.contentView addSubview:left];
right = [[[UILabel alloc] initWithFrame:rightF] autorelease];
right.tag = kRightLabel;
[cell.contentView addSubview:right];
}
else{
left= (UILabel*)[cell.contentView viewWithTag:kLeftLabel];
right = (UILabel*)[cell.contentView viewWithTag:kRightLabel];
}
profileDB *Obj = [appDelegate.profileArray objectAtIndex:indexPath.row];
left.text = Obj.profileName;
right.text = Obj.id;
return cell;
}
我想只为选定的单元格读取右列的文本。
这可能吗?
答案 0 :(得分:3)
首先,您必须找出所选的单元格。
- (void) tableView:(UITableView*)tableview didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
UITableViewCell *cell = [tableview cellForRowAtIndexPath:indexPath];
for(UILabel *lbl in [cell.contentView subviews])
{
if(([lbl isKindOfClass:[UILabel class]]) && ([lbl tag] == 101))
{
NSString *str = lbl.textLabel.text;
}
}
}
如果您在单元格上添加了子视图,则可以使用其标记
来指定特定标签的文本
