如何使用多线程在UITableView中显示json图像数组？

#import "ViewController.h"
#import <JSONKit/JSONKit.h>

@interface ViewController ()

@property (nonatomic, strong) NSMutableArray *images;
@property (nonatomic, strong) IBOutlet UITableView *tableView;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  // Load JSON data
  NSString *jsonString = @"{\"images\": [{\"url\": \"https://example.com/image1.jpg\"},{\"url\": \"https://example.com/image2.jpg\"},{\"url\": \"https://example.com/image3.jpg\"}]}";
  NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
  NSError *error;
  self.images = [NSMutableArray array];
  [self.images addObjectsFromArray:[NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error]];

  // Create thread
  dispatch_queue_t queue = dispatch_queue_create("com.example.jsonParsingQueue", nil);
  dispatch_async(queue, ^{
    // Parse JSON data
    for (NSInteger i = 0; i < self.images.count; i++) {
      NSDictionary *imageDict = [self.images objectAtIndex:i];
      NSString *imageUrl = [imageDict objectForKey:@"url"];
      [self.images addObject:@{@"url": imageUrl, @"index": @(i)}];
    }

    // Update UITableView
    [self.tableView reloadData];
  });
}

@end
