good use of ASIHTTP ?

[logan]

this is my code.it 's good or not because i try to get somes pictures from URL in background (asynchronous)?

if (![self queue]) {
			[self setQueue:[[[NSOperationQueue alloc] init] autorelease]];
		}
		
NSURL *url = [NSURL URLWithString:@"http://*******.php"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:@selector(requestDone:)];
[request setDidFailSelector:@selector(requestWentWrong:)];
[[self queue] addOperation:request]; //queue is an NSOperationQueue
	}
	

- (void)requestDone:(ASIHTTPRequest *)request{
    NSString *response = [request responseString];
     self.online = [response JSONValue];
    for(int i=0;i<[online count];i++)
            		{           			        			
            			NSDictionary *dict=[online objectAtIndex:i];
                  			
        NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
            			
            			
        NSString* pict =  [documentsPath stringByAppendingFormat:@"/%@_%@",[dict objectForKey:@"1"],[dict objectForKey:@"6"]]; 
            			
            			
        NSString* pseudoTof = [NSString stringWithFormat:@"%@_",[dict objectForKey:@"1"]];
            			
            			
        BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:pict];
            			
            			
        if (fileExists)	{
            				
            			
            			}else {
            										
            				
        if([pict rangeOfString:pseudoTof].location != NSNotFound) 
            					
            				{								
            					
        NSFileManager *fileManager = [NSFileManager defaultManager];
            					
        [fileManager removeItemAtPath:pict error:NULL];
            											
            				}
            				
            				
        else {
            									
            
            													
            				
  NSString *string=[dict objectForKey:@"5"];
            							
  	
        NSURL *finalURL = [NSURL URLWithString:[string stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
            				
            				
        NSURL *url=[NSURL URLWithString:string];
            				
            				
            				
        UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL: finalURL]];
            				
            				
            				
            				
        NSData *data2 = [NSData dataWithData:UIImageJPEGRepresentation(image, 0.5)];//1.0f = 100% quality
            				
            				
        [data2 writeToFile:pict atomically:YES];
            									
            				
            			}
            			
            			
            		}				
            				
        [salonTbView reloadData];
            			
            				
            		
            	}
            	
            	- (void)requestWentWrong:(ASIHTTPRequest *)request

That was a really, really quick thread bump.

What was your question, anyway?

hi

just want to know if it will be slow on the iphone.

so first i have to download pictures and put them in tableview like that

  
    // Configure the cell...
	
	dico = [self.pseudoOnline objectAtIndex:indexPath.row];
	cell.text =  [dico objectForKey:@"1"];
	cell.detailTextLabel.text = [dico objectForKey:@"2"];
	
	NSString* documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
	NSString* pict =  [documentsPath stringByAppendingFormat:@"/%@_%@",[dico objectForKey:@"1"],[dico objectForKey:@"6"]];
	
	
	
	BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:pict];
	
	cell.image = [UIImage imageWithContentsOfFile:pict];
	
	return cell;
