UIImageView到UITableViewCell

Question

I get images for JSON.like this:-

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{

    NSMutableArray *al=[NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
    for (NSDictionary *diction in al)
    {
        NSString *geting =[diction valueForKey:@"dealimage"];
        NSLog(@"dealimage is %@",geting);

        NSData *getdata=[[NSData alloc]initWithData:[NSData dataFromBase64String:geting]];
        NSLog(@"good day %@",getdata);
        dataimages=[UIImage imageWithData:getdata];
        NSLog(@"dataimages %@",dataimages);

        [imagesarray addObject:dataimages];

     }
    NSLog(@"images array is array%@",imagesarray);
     NSLog(@"dataimages 8images %@",dataimages);
}

When i print images array it show like this:-

images array is array(
    "<UIImage: 0x7539b70>",
    "<UIImage: 0x7176e00>",
    "<UIImage: 0x7182960>",
    "<UIImage: 0x7185d40>",
    "<UIImage: 0x7541d00>",
    "<UIImage: 0x7186e30>",
    "<UIImage: 0x7186ff0>",
    "<UIImage: 0x7187410>"
)

What I tried is NSString to pass to NSData via Base64String and then NSData pass to UIImage and then UIImage pass to the NSMutablearray(imagearray).Now i pass the this array to UITableViewCell like is:-

cell.imageView.image = [imagesarray objectAtIndex:indexPath.row];

But images are not display in UITableViewCell So Please give me any idea about my problem . Thanks in Advanced

Answer 1

The way of loading image in to Table-view from Json is wrong. Better to load array with imageURL and load its Image from URL in to the CellForRowAtIndex : method

For example:

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{

    NSMutableArray *al=[NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
    for (NSDictionary *diction in al)
    {
        NSString *geting =[diction valueForKey:@"dealimage"];
        NSLog(@"dealimage is %@",geting);
        [imagesarray addObject:geting]; // here adding image URL in side the Array

     }  

  [self.tableview reloadData];
}

and CellForAtIndex:

  cell.imageView.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[imagesarray objectAtIndex:indexPath.row]]]];

And for better smooth parformance use asynchronous image loading with help of SDWebImage or many other library that load you image from url with catch and performance faster.

Answer 2

 NSLog(@"images array is array%@",imagesarray);

 yourTableView.dataSource = self;//or your object

 [yourTableView reloadData];

will make table view to refresh the data.

if you didn't set the dataSource then table view will not look for table data to show.
