How to tell how much text is displayed in a multiline label

Patrick MacDonald 5

If I have a multiline label and I programmatically fill it with characters, how can I tell when I put the last displayable character in the label? I can keep adding characters but they won't be visible. So how can I figure out when to stop adding characters. Or how can I compute how many characters will fit on the visible portion of the label?

Since the width of characters is varying in case of usual proportional fonts, it is difficult to compute the number of characters in advance without knowing the text. The fixed-with fonts can be used instead. Maybe there is a different solution depending on specific needs.

Which platforms do you want to implement it? Do you have set specific width, character size and lines for Label?

Currently I’m just developing for iOS. I’m using fixed width fonts. The label width varies depending on the device - the label in an iPad in landscape mode is much larger than an iPhone on portrait mode.

Firstly, we can do this by checking the platforms and device types. Please see Device information. After that, you can create a Label's handler and use UIView.IntrinsicContentSize Property to do it
