問題描述
ASIHTTPRequest 緩存我的數據。我不想要任何類型的緩存 (ASIHTTPRequest caches my data. I don't want any kind of cache)
I have a big app. It initially assumed 20 MB RAM.
I want for example to download a 14 MB opera. After a few minutes I downloaded an opera. My application RAM increase from 20 to 34 MB. This is big problem because if I want to download 200 MB file my app will be killed.(14+200). I tried several times and I got "did received memory warning" and then app was killed.
ASIHTTPRequest caches my data. I don't know why. I even removed all code from request: didReceiveData:. But It didn't helped me.
IMPORTANT: I created a new empty project and added this code. In this project everything works well. ASIHTTPRequest don't cache any data. May be I need to change XCode settings?
-(void) downloadOpera
{
self.currentPath = @"http://get-tsw-1.opera.com/pub/opera/mac/1164/Opera_11.64_Setup_Intel.dmg";
self.ASIRequest = [[[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:currentPath]] autorelease];
ASIRequest.delegate = self;
ASIRequest.shouldContinueWhenAppEntersBackground = YES;
[ASIRequest setCachePolicy:ASIDoNotWriteToCacheCachePolicy];
[ASIRequest startAsynchronous];
}
- (void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data {}
- (void)requestFailed:(ASIHTTPRequest *)request {}
- (void)requestFinished:(ASIHTTPRequest *)request {NSLog(@"download finished");}
