Async Image Loading Performance - ios

Question

I am loading images in UITableViewCell receiving from url using below code, everything is working fine but the image load very slow in UITableViewCell and if i think as a user, it is not acceptable.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [checkData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSInteger i =indexPath.row;
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
UIImageView propertyImage = (UIImageView *)[cell viewWithTag:10];
NSString *test = [[checkData objectAtIndex:i]valueForKey:#"image"];
CGRect frame=propertyImage.bounds;
AsyncImageView asyImage=[[AsyncImageView alloc] initWithFrame:frame];
[asyImage setImage:[UIImage imageNamed:#"loading.png"]];
self.urlForTesting=[NSURL URLWithString:test];
[asyImage loadImageFromURL:self.urlForTesting];
asyImage.imageURL =self.urlForTesting;
asyImage.contentMode = UIViewContentModeScaleToFill;
asyImage.layer.masksToBounds=YES;
[propertyImage addSubview:asyImage];
return cell;
}

Use AFNetworking Class & add additional two file to download from github "UIImageView+AFNetworking" and import in your project. then after add this code from "cellForRowAtIndexPath"
// Fetch Image from URL
NSURL *url = [NSURL URLWithString:[[checkData objectAtIndex:i]valueForKey:#"image"]];
[objWinner.actWinner startAnimating];
[objWinner.actWinner setHidden:NO];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[objWinner.imgwinner setImageWithURLRequest:req placeholderImage:nil success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
[objWinner.actWinner stopAnimating]; // this is Activityindicator
[objWinner.actWinner setHidden:YES];
objWinner.imgwinner.image = image;
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
}];
