Hi,

you can consider the pdf page like a normal view and add objects with standard development methods.

Hii, thanks for the reply.

I tried that, but when i need to add button where the page starts.

Please look at the attachment below.

I need to add the button at position 2.
But using above approach, button is set at posiiton 1.

Hi,

to get the correct position you should calculate it with something like:

Code:

//Get the vPage 
PDFVPage *vvpage = [m_view vGetPage:m_cur_page];
    //Get the page position
    int x = [vvpage GetVX:[m_view vGetX]];
    int y = [vvpage GetVY:[m_view vGetY]];
    //Get the correct position using scale
    float logicx = x/m_scale;
    float logicy = y/m_scale;
    //Use contentOffset to get the view position on the scrollView
    CGRect exampleRect = CGRectMake(logicx + self.contentOffset.x, logicy + self.contentOffset.y, 50, 50);

Thanks, that was some good advise.

But i need a solution where we can add button on PDFVPage itself, not on the view it is contained in.

Hi,
PDFVPage is a NSObject and not contains a view, but draw the page content on a canvas using CG methods.
If you want to add objects on a page, you should use annotations or add subviews on the scrollview with the sample code of the previous post.
