What does autoresize = RM+BM mean?
提问by brainray
I get this when using the Xcode debugging console with this line:
使用带有以下行的 Xcode 调试控制台时，我得到了这个：
po [[UIWindow keyWindow] recursiveDescription]
Then I get back lines with the recursive description like this
然后我得到像这样递归描述的行
<UILabel: 0xb0b8170; frame = (138 106; 200 15); text = 'Distance'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0xb0b8220>>
What does "autoresize = RM+BM" and is there a place I can lookup the meaning of the letters? I also saw something like this "autoresize = LM+W+RM+TM+H+BM".
“autoresize = RM+BM”是什么意思，有什么地方可以查到字母的意思吗？我还看到了类似这样的“自动调整大小 = LM+W+RM+TM+H+BM”。

autoresize indicates which bits have been set in the autoresizingMask:
autoresize 指示在 autoresizingMask 中设置了哪些位：
RM = UIAutoresizingFlexibleRightMargin
BM = UIAutoresizingFlexibleBottomMargin
The others follow a similar abbreviation syntax.
其他的遵循类似的缩写语法。
