有什么方法可以将 UILabels 与不同的字体底部对齐吗？
我在自定义 UITableViewCell 的 contentView 中有一个 UILabels 数组。每个标签的字体大小通过排名来形成标签云。在设置单元格（行）的方法中，我迭代适合该行的单词对象，为每个 UILabel 设置框架，如下所示：
CGRect theFrame = CGRectMake(xPosAdjuster,
theWordRow.rowHeight - thisWord.lblHeight,
thisWord.lblWidth,
thisWord.lblHeight);
UILabel *myLabel = [[UILabel alloc] initWithFrame:theFrame];
这使标签的框架对齐（参见下图），但是不幸的是，标签的填充是字体大小的函数。
有没有办法删除 UILabel 上的填充（边框）和/或精确计算它以便我可以调整相应的帧的 y 位置？
谢谢
I have an array of UILabels inside the contentView of a custom UITableViewCell. The font of each label is sized by ranking to form a tag cloud. In the method that sets up the cell (row), I iterate through the word objects that will fit on that line, setting up the frame for each UILabel as follows:
CGRect theFrame = CGRectMake(xPosAdjuster,
theWordRow.rowHeight - thisWord.lblHeight,
thisWord.lblWidth,
thisWord.lblHeight);
UILabel *myLabel = [[UILabel alloc] initWithFrame:theFrame];
This gets the frames of the labels aligned (see image below), but, unfortunately, the labels have a padding that is a function of the font size.
Is there any way to remove the padding (border) on a UILabel and/or calculate it exactly so I can adjust the y pos of the frames accordingly?
Thanks

这是我排列标签的最终代码：
Here is my final code that lines up the labels:
您可能需要查看此页面。苹果文档上有信息，但这是我发现的第一个。
因此，您似乎必须根据
UIFont的下降部分进行一些计算。您可以轻松获取此值，它被定义为 UIFont 上的属性。You may want to take a look at this page. There is information on Apple's Docs, however this was the first I found.
So it looks like you'll have to do some calculation based on the descender of the
UIFont. You can easily get this value, it is defined as a property onUIFont.
