Changing the line spacing property of an NSParagraphStyle causes the cursor to lengthen

Question

I have a subclass UITableViewCell containing a UITextView. I added NSParagraphStyle as an attribute for a string in a subclass of NSTextStorage. In the following code, I increased the space between each row in a UITextView.

speed

let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.lineSpacing = 11 myCustomTextStorage.appendAttributedString(NSAttributedString(string: someText, attributes: [NSParagraphStyleAttributeName: paragraphStyle])) 

The height of the cursor extends to the height of the next line, as shown below. This only happens in lines to the last line.

I looked through several posts on this subject, including this post ; however, none of the proposed solutions seem to work for me.

I read the TextKit documentation but could not find a solution for this problem.

Is there a way to reduce the height of the cursor?

Answer 1

This works the same as on a Mac. It is intended to provide the user with visual feedback on which line they are on and at the height of that line. You have to think a lot before changing this, because you don’t like what it looks like.

However, the method in the SO message that you linked above is a general approach to setting the cursor (although the adjusted direct origin may need to be adjusted as well). What didn’t work with you? Better to start from now on.

This topic gives an answer related to this problem. just pasting here for future reference. iOS - UITextView lineSpacing makes cursor height not the same

"you can change the height of the cursor by subclassing the UITextView, then override the caretRectForPosition: position function. For example:

• (CGRect) caretRectForPosition: (UITextPosition *) position {CGRect originalRect = [super caretRectForPosition: position]; originalRect.size.height = 18.0; return originalRect; } "
