I have found the reason of slow loading. because I want to make my APP is fluent. so I used the asynchronous processing. but it has extended the loading time. I don't understand why! We only load the PDF on the main thread? And I found load PDF with the main thread in the demo. Why don't we use multithreading and can you tell me how to modify?

Hi,

a process started in in an asynchronous thread, is a low priority process, so the download process could take much time.
You should try to call only the download process on main thread.

I want to know do you have a way to solve this problem, asynchronous and fast.

you can do all the operations in background, but, to avoid delays, the PDFOpenStream method and the UI activities should be called on main thread.
Something like:

Code:

[self performBlockOnMainThread:^{
        [m_pdf PDFOpenStream:httpStream :@""];    
        m_pdf.hidesBottomBarWhenPushed = YES;
        [self.navigationController pushViewController:m_pdf animated:YES];
}];
