UILabel中的自动收缩仅适用于宽度吗？

Question

I have some ASCII syntax diagrams which must not have line breaks in the middle.

These don't have to be editable so I thought the best way is to use an UILabel with auto shrink option. But this option shrinks the text also if the content doesn't fit the height of the labels frame rectangle.

I just want to shrink only if the content doesn't fit the width. It would be absolutely fine to scroll vertically through the text.

What is the best way to do this with UILabel or any other UI element?

Answer 1

使用UITextView，将“ editable”属性设置为false。

Answer 2

So let me rephrase your question. I guess what you want is a UILabel which can show multiple lines, but the longest line need to fit into the width of UILabel. If this is what you want, well the imagination is weird to me...

But anyway, I feel there's a conflict in your settings. First, allowing multiple lines implies you set "Lines" attribute (number of lines) as 0, which allows unlimited lines. But then Autoshrink will play no effect. I'm afraid it is not possible to be done by just setting the storyboard and instead, you need to write some code.

I guess people have raised related questions earlier, by which they want to dynamically change the font size when the text become too long. I guess you want to take a look about this:

The last issue is you also want the scrolling effect (this is why I feel the outlooking will be weird.) But in short, to achieve this you need 1) dynamically change the UILabel height, most likely using the same technique as explained in the reference thread, and 2) wrap the UILabel in a scroll view. Maybe this can achieve what you want.
