UITableViewCell样式中使用的默认字体设置是什么？

Question

任何人都有苹果在UITableViewCells，UILabel等中使用的默认字体设置列表？同样，UITableViewCell中textLabel的定位信息都是分组的，并且非常棒。

您是否熟悉调试器？它知道所有。要访问布局，请在gdb中尝试以下内容。

我设置的断点在- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath显示单元右侧前

被称为（注：有一个背景图像在我的细胞）

(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 =打印对象 p =打印，但您必须将值转换为您知道的类型

无资产访问cell.frame - 使用objective-c方法[cell frame]

我创建了一个UITableViewCell的子类来获取这些值。我的继承人代码：

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); 

输出：
