hi, all
In my application, I want to download a file from internet. so I use
NSURLDownload to do it. and using NSRunLoop to wait until finish the
downloading action. for example 2 seconds. codes as the following
[downloadFile setDestination:downloadPath allowOverwrite:YES];
[[NSRunLoop currentRunLoop] runUntilDate:[NSDate
dateWithTimeIntervalSinceNow: 2 ]];
it works correctly.
But I think it is too long time for the users who will use my
application. and I can change 2 seconds to 0.5 seconds, but how to do
if my server file is too large to download in 0.5 seconds.
and if I use
[[NSRunLoop currentRunLoop] run];
and use NSURLDownload delegate method, the following, to stop the
loop, it can not work well.
- (void)downloadDidFinish:(NSURLDownload *)download
{
//....
NSApplication *app = [NSApplication sharedApplication];
[app stop:self];
}
using the stop method, It looks like to stop my whole application.
I have the problem for many days. I found the sample ImageClient in
apple web site.
http://developer.apple.com/samplecode/Cocoa/idxNetworking-date.html
It uses CFNetwork, but it also looks use several seconds to wait until
the download finish. I want to finish the download automatically when
the download finished.
anyone can help me?
thank you
