Highlight text annotation on selection

Hi,
I need to highlight the note annotation with a black border on annot select.
I am not able to find the code to do that.
Please help me in identifying the code.

Hi,

the annot rect is set when onSingleTap of PDFView class is called.
Then you can take a look at drawAnnot method to draw the black rectangle to highlight the annotation.

If i am trying to call the drawAnnot method by passing context as UIGraphicsGetcurrentContext() then context is nil.
Please give me possible solution for this?

Can you please better explain the steps of your custom implementation?
It's possible that you are calling drawAnnot method when the page is not loaded?
