What are the default font settings used in the UITableViewCell styles?

Question

Anyone have a listing of the default font settings Apple uses in the UITableViewCells, UILabel etc? Also the positioning information for the textLabel in the UITableViewCell both grouped and plain would be fantastic.

Answer 1

Are you familiar with the debugger? It knows all. To get access to the layout, try the following in gdb.

I set the breakpoint in - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath which is called right before the cell is displayed

(note: there's a background image in my cell)

(gdb) po cell
<UITableViewCell: 0x59e9920; frame = (0 66; 320 44); text = '396 Studio'; autoresize = W; layer = <CALayer: 0x59e9a00>>

(gdb) po [cell subviews]
<__NSArrayM 0x4eaf730>(
 <UIImageView: 0x59ea660; frame = (0 0; 320 100); opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x59ea690>>,
 <UITableViewCellContentView: 0x59e9eb0; frame = (9 0; 302 44); layer = <CALayer: 0x59ea070>>
)

(gdb) po [[[cell subviews] objectAtIndex:1] subviews]
<__NSArrayM 0x4eaf700>(
 <UILabel: 0x59e9170; frame = (0 0; 0 0); text = '396 Studio'; clipsToBounds = YES; userInteractionEnabled = NO; layer = <CALayer: 0x59e91e0>>,
 <UITableViewLabel: 0x59e65c0; frame = (0 0; 0 0); text = 'Houston'; clipsToBounds = YES; userInteractionEnabled = NO; layer = <CALayer: 0x59e6690>>
)


(gdb) po [0x59e9170 font]
<UICFFont: 0x5e12610> font-family: "Helvetica"; font-weight: bold; font-style: normal; font-size: 0px


(gdb) p (CGRect)[cell frame]
$1 = {
  origin = {
    x = 0, 
    y = 66
  }, 
  size = {
    width = 320, 
    height = 44
  }
}

po = print object p = print, but you have to cast the value to the type you know it is

no property access cell.frame - use objective-c methods [cell frame]

I subclassed a UITableViewCell to get these values. Heres my code:

  dlog(@"%@",self.detailTextLabel.font);
  dlog(@"%@",self.detailTextLabel.bounds);
  dlog(@"%f",self.detailTextLabel.frame.size.height);
  dlog(@"%f",self.detailTextLabel.frame.size.width);
  dlog(@"%f",self.detailTextLabel.frame.origin.x);
  dlog(@"%f",self.detailTextLabel.frame.origin.y);
  dlog(@"%@",self.detailTextLabel.textColor);

output:
