Answer 1

 NSMutableArray *imagearray=[NSMutableArray new];  // this is your tableArray

    NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:receivedData options: kNilOptions error:nil];   // your json response started with Dictionary

    NSArray *imagekey=[[jsonDict objectForKey:@"results"]objectForKey:@"results"];

    for (NSDictionary *tmp in imagekey)
    {
        NSDictionary *tmpimagekey=[NSMutableDictionary new];

         [tmpimagekey setValue:[tmp objectForKey:@"image"] forKey:@"image"];

        [imagearray addObject:tmpimagekey];

    }
    [yourtableName reloadData];

您的cell方法

中的

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

// here cell process

NSData * imageData = [[NSData alloc] initWithContentsOfURL：[NSURL URLWithString：[NSString stringWithFormat：@“herpassyourURL /％@”，[[imagearray objectAtIndex：indexPath.row] objectForKey：@“image”]]]]; UIImage * image = [[UIImage alloc] initWithData：imageData];

[yourbuttonName setImage:[UIImage imageNamed:image] forState:UIControlStateNormal];

[yourbuttonName addTarget:self action:@selector(imagebuttonclicked) forControlEvents:UIControlEventTouchUpInside];

[cell.contentView addSubview:yourbuttonName];


       return cell;
}

-(void)imagebuttonclicked
{
// do ur stuff
}
