First :
setInvalidate method not found !

i search "setInvalidate" but we can't find it in xcode project!
seccond i use on this method :
-(void)OnSingleTapped:(float)x :(float)y
{

[pdf_view vClearSel];
[m_searchBar resignFirstResponder];

if(m_Thumbview.hidden)
{
m_Thumbview.hidden = NO;
[self.pageNumLabel setHidden:false];
}
else
{
m_Thumbview.hidden =YES;
[self.pageNumLabel setHidden:true];
}
}

sorry, i forgot method name in UIView class.
it like this:
[pdf_view vClearSel];
[PDFView setNeedsDisplay]

means redraw UIView

It might be a null pointer of variable pdf_view.
You would like to add -(void) vClearSel method to PDFView.h interface
and use it.

Code:

// PDFView.m
- (void)vClearSel
{
	[m_view vClearSel];
}

// RDPDFViewController.m
-(void)OnSingleTapped:(float)x :(float)y
{
	[m_view vClearSel];
        [m_view setNeedsDisplay];

	/** **/
}
