I'am developing a newsstand application and i want to read the content of the pdf while its downloading. Currently the user has to wait until the pdf downloads to read it. In some newsstand apps i have seen the users can read while the pdf pages are downloading.
I just want to know from where do i start. It would be great if anyone could guid me on this.
I solved my problem by keeping my large pdf as splited pdf files. Then download the pdf to the iphone and combined the pdf files i downloaded.
So until the next pdf downloads user can read the downloaded pdf.Once the other pdf is downloaded the new part is combined to the first pdf to create a new pdf. Thanks.
