PDF Annotation Highlighter and Pen Tool not working

[yhelfronda]

Hi,

I'm currently using your library on my existing project but I have an issue when using the highlighter and pen. If your using just one finger it doesn't work but when I tried 2 fingers it worked. I don't know what causes this issue. But when I try to use it on new project one finger worked when using pen and highlighter

Here's CG_CONTEXT_SHOW_BACKTRACE:

I have this feeling you may not be understanding how the toolbar UI seems to be built - if you use the default tools, touching the "Pen" expands it to allow you to choose between Pen and Highlighter. You have to pick one of those, then it will work.

There is a separate issue that while signing, two-finger touches will both zoom the page and start drawing a new annotation from the first finger (less good). But, that's a separate thing.
