Download an asynchronous multiple images in UITableViewView? - iphone

Question

How can i download an asynchronous multiple images in the UITableView using ASIHttpRequest or something useful?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
..........
// Creation
UIImageView *avatar;
UILabel *content;
// Tag the IBOutlets
avatar = (UIImageView*)[cell viewWithTag:14];
content = (UILabel*)[cell.contentView viewWithTag:4];
// Field
avatar.image = image
content.text = entryReviewtableView.content;
}

Answer 1

No need to introduce a dependency to a whole framework such as ASIHTTPRequest just to download one image, when you can do it a few easy lines of code using GCD:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData *imageDate = [NSData dataWithContentsOfURL:imageURL];
UIImage *image = [UIImage imageWithData:imageData];
dispatch_async(dispatch_get_main_queue(), ^{
avatar.image = image;
});
});
This is asynchronous and all the goodness. But in a few lines of code you can write, understand, bug-fix, extend and maintain yourself.

You can be use the asynchronous image view instead of the default image view. for reference you can visit tutorial Here.

Answer 3

UIImageView *imgV=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 1024, 748)];
ASIHTTPRequest *req=[ASIHTTPRequest requestWithURL:[NSURL URLWithString:[Array objectAtIndex:indexPath.row]]];
[req setUsername:[NSString stringWithFormat:#"%i",i]];
[req setUserInfo:[NSDictionary dictionaryWithObjectsAndKeys:imgV,#"imgV",nil]];
[req setDelegate:self];
[req startAsynchronous];
//[imgV setContentMode:UIViewContentModeScaleToFill];
[imgV setContentMode:UIViewContentModeScaleAspectFit];
//[imgV setClipsToBounds:YES];
[imgV setTag:kTagImageViewInScrollView];
[cell addSubview:imgV];
- (void)requestFinished:(ASIHTTPRequest )request {
[(UIImageView)[[request userInfo] valueForKey:#"imgV"] setImage:[UIImage imageWithData:[request responseData]]];
[(UIActivityIndicatorView*) [(UIScrollView*) [scr viewWithTag:([[request username] intValue]+1)] viewWithTag:kActTag] removeFromSuperview];
}
