I've forked this open source PDF reader code from vfr/Reader and merged it with KurtCode/PDFKitten, from which I developed my app to support Simplified-Chinese text Searching.

Supports:

• Simplified-Chinese Text Searching.

Not Every PDF is guaranteed. Not Tested on IPhone.

• vfr/Reader
• KurtCode/PDFKitten
