self = [super initWithFrame:frame];
if (self)
{
m_doc = NULL;
m_view = nil;
m_scale = [[UIScreen mainScreen] scale];
m_w = frame.size.width;
m_h = frame.size.height;

then go to m_view = [[PDFView alloc] initWithFrame:CGRectMake(0, 0, rect.size.width, rect.size.height-20-hi)];
& delete -20-hi but it's not work for first [it need to rotate the screen]

Did you adjust the frame in singleTap action?

no
i change the frame in

-(int)PDFOpen:(NSString *)path : (NSString *)pwd
{

///
m_view = [[PDFView alloc] initWithFrame:CGRectMake(0, 0, rect.size.width, rect.size.height)]; // delete your value !
it's work but need a rotate to apply


}

Is this view add to superview?

[self.view addSubview:m_view];

you can try to move the entire view when you hide/show the navBar, something like:

CGRect tempFrame = self.view.frame;
tempFrame.origin.y -= self.navigationController.navigationBar.frame.size.height;
[self.view setFrame:tempFrame];

on single tap event
