Pdf Quality lost when zoomed
Mandar07 opened this issue · comments
Firstly, a great UIImage-PDF category. Makes it look so simple.
After integrating and running the app,
(I added a scrollView and a UIImageView added as its subview) , when I zoom into, the pdf quality is completely lost.
Any fix for this?
Thankx in advance
Hi. UIScrollView is simply zooming the rendered PDF bitmap. For PDF zooming the best solution is to use a CATiledLayer. Apple's demo code is here: https://developer.apple.com/library/ios/samplecode/zoomingpdfviewer/Listings/ReadMe_txt.html
