NativeScript: max number of lines on a Label - nativescript

If I add textWrap="true" to a Label, text is wrapped over several lines, so far so good.
But I have a very long string and our design only have room for two lines.
How do I limit the Label to max two lines?
I'd prefer not to set a height, since that would leave an empty line for texts that could fit on one line?

Let's try this:
For Android:
myLabel.android.setMaxLines(2);
For iOS:
myLabel.ios.numberOfLines = 2

To add an ellipsis('... ') at the end to indicate that the text is cutoff, implement the directive at the below link. The above one doesn't have any,

Find the number of displayed lines, with folding in Ace

Within an Ace editor, it is easy to find the number of lines in the edited document with the following:
myEditor.session.getLength();
But languages like JSON or XML can be "folded." That is, children properties or elements can be collapsed so only one single line is displayed for the parent.
Is there a way to get the number of lines actually displayed? Something like the following:
myEditor.session.getVisibleLength();
Note: the ultimate goal is to have an editor that adapts its height on the page to the content it displays (if lines are collapsed, then it should shrink, and if collapsed lines are expanded again, it should increase its height.)
UPDATE: After a user's response, I use the following. This is not the answer to the specific question I asked above, but rather the perfect answer to what I was trying to achieve overall:
const myEditor = ace.edit(elem, {minLines: 5, maxLines: 50});
To automatically change the height of the editor use maxLines option, but don't set it to a very large value as performance depends on the number of displayed lines.

How to make two rows of words as big as one word in InDesign?

Im not sure how to express it so I posted a picture in link below.
It should look like this
Just enter the text on 3 lines like so:
MORE
AT
THE HALL
Then adjust the point sizes, leading, kearning, etc. to create the aesthetic you want.
In this case line 1 and 3 could have full justification.
You can use scaling of the text(as shown in the character panel in attached snapshot) because changing font size also moves the baseline and causes the text to shift downward.
These attributes are also exposed via scripting.

ZPL Center text vertically

Is there a way in ZPL to center text vertically?
I know I can use ^FO0,0^ASN,50^FB200,3,0,C,0^FD TEXT ^FS. But how can I make that print on the 2nd line if it's short enough?
There isn't a vertical centering feature, but you can fake it, if you know in advance that your string is short enough to fit on the middle line.
Your ^FB defines a field block that is three lines. So your best option is to determine if your string fits on one line... and if it does, insert a "\&" before your string.
^FO0,0^ASN,50^FB200,3,0,C,0^FD\&TEXT^FS

Xcode how to Autoshrink a UITextView?

I have a Text View box and I want that rectangle to stay the same size while the text inside autoshrinks to fit the box. The reason I need this is because the text is pulled from a plist and the strings are all different lengths. Labels have an Autoshrink feature which is exactly what I want, but I can't figure out a way even through code to get a Text View to do the same thing. Please help!
UILabels can have more than one line of text. You just need to set the following:
label.lineBreakMode = UILineBreakModeWordWrap;
label.numberOfLines = 0; // 0 = unlimited number of lines, set to another number to have that as maximum
I'm not entirely sure if this works, but you can then combine this with label.adjustsFontSizeToFitWidth = YES; to have a multi-line label that autoshrinks text.

Position of Text in a TextBox

Hi I have a textbox containing some text. I am looking to replicate the red spelling mistake squiggle type behaviour.
Using WinAPI I can
draw the squiggle between 2 points.
find out the height and width of
the word to be "squiggled".
What is the api call (or perhaps the methodology if it is more than a single api call) to find the position of that word in the text box so that I can position the sqiggle undeneath it.
Also, what are the messages I need to trap to ensure that the squiggle is redrawn. I'm currently only using WM_PAINT, which obviously isn't good enough.
EDIT (3 Sept 2012):
FYI, Here's where I got to so far. Needs a lot of refining but shows basic principles

What might work is using an auto-sized label. Make sure the fonts in the label and textbox are identical.
Detect the number of rows that are before the sentence containing the misspelled word.
Fill the label caption with the number linefeeds (vbcrlf) you got from question 1.
Append the words from the misspelled line (up to the misspelled word) to the labels caption.
The label size should now be identical with the beginning of the misspelled word.
Example text:
This is my first line.
And my second line.
And over here i have my mispeled word.
Label caption output should be (ignore the dots, they are empty lines):
.
.
And over here i have my
The labels height and width should match the position in the textbox, unless you have scrollbars. If the textbox has borders then you should add a fixed value to the height and width to get an exact match.
