UITableViewCell 附件视图不显示

Question

Im totally unsure why my accessory view is not working. I simply want some text to appear to the right of the UITableViewCell (as well as the left), but only the text on the left is displaying.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

  UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"SwitchCell"];

  if (cell==nil){
      cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"SwitchCell"] autorelease];
      UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(5, 0, 60, 30)];

      cell.textLabel.text = @"left text";
      label.text = @"right text";

      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

      cell.accessoryView = label;
      [label release];

  }
  return cell;
}

Any ideas? Thanks.

Answer 1

cell.accessoryView = label;

You are setting your accessoryView to be a label so you're not going to see any disclosure indicator. If you want title and detail text in your cell then init it with UITableViewCellStyleValue2 like this...

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:@"cellType"] autorelease];

...and then set the title and detail like this...

cell.textLabel.text = @"Title";
cell.detailTextLabel.text = @"Description";

To get an idea of the different built in table styles check the following image...

You can adjust the textLabel and detailTextLabel to suit your taste.

Answer 2

Why this? You can't have both.

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

Answer 3

-(id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier

was depreciated in iOS 3.0

Instead use:

-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier

Pass in either UITableViewCellStyleValue1 or UITableViewCellStyleValue2 and set the textLabel and detailTextLabel properties as you need.

Answer 4

UITableViewCellStyleValue2 gives me a weird style. I think the most commonly requested style is UITableViewCellStyleValue1 (at least for my case).

Answer 5

Also remember: accessoryType property is ignored if you have custom accessoryView. So, this line of code is excess.
