I keep needing to find this out, so I thought I’d post it here so I can refer to it. This is the geometry of the UILabels for each of the UITableViewCellStyles:

UITableViewCellStyleValue2
textLabel: 10.000000 : 14.000000 : 68.000000 : 16.000000
detailTextLabel: 83.000000 : 12.000000 : 207.000000 : 0.000000
