问题
I have a dynamic multi line UILabel and need to know the end of the text (X Coordinate) of the visible text (not the Label) so I can show something after the text. Is this possible?
thank you

You'll be able to have more control over the text layout with the CoreText framework. Checkout the documentation:
There are also some nice open source things that already do a lot of the hard work for you, like: https://github.com/Cocoanetics/DTCoreText

As far as I know , the best solution for this is to use a UIWebView instead of a UILabel. You just have to format the HTML for it to load and then add whatever you want to add after.
Example:
[webView loadHTMLString:[NSString stringWithFormat:@"<html><body><font face=\"arial\" size=\"2\">%@</font><font face=\"arial\" size=\"1\"> %@</font></body></html>",text1 , text2] baseURL:nil];
If you want to keep trying with UILabel / UITextView /any UIView for that matter , I only know of a way to figure out the height properly : [myView sizeToFit]; And then get it's frame.
Hope this helps.
Regards,
George
