我能够将 json 文件解析为 tableview，但我不知道如何获取电影标题并将其作为标题传递给我的详细视图。下面是我的方法

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"movieCell";

    movieCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    id video = [self.model.videos objectAtIndex:indexPath.row];
    NSString *rl = [video objectForKey:@"release_date"];
    NSString *imageURL;
    if ([[video objectForKey:@"poster_path"] class] != [NSNull class])
        imageURL = [video objectForKey:@"poster_path"];
    else
        imageURL = @"icon.jpg";

    if (rl != (NSString *)[NSNull null]){
            NSString *dateStr = rl;
            // Convert string to date object
            NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
            [dateFormat setDateFormat:@"yyyy-MM-dd"];
            NSDate *date = [dateFormat dateFromString:dateStr];

            // Convert date object to desired output format
            [dateFormat setDateFormat:@"MM/YYYY"];
            NSString *released = @"Released: ";
            NSString *fullDate;
            dateStr = [dateFormat stringFromDate:date];
            fullDate = [NSString stringWithFormat:@"%@ %@", released, dateStr];
            cell.videoDescriptionLabel.text = fullDate;
    }
    else{
        cell.videoDescriptionLabel.text = @"N/A";
    }
    cell.videoTitleLabel.text = [video objectForKey:@"title"];      
    NSString* thumbnailURL = [NSString stringWithFormat:@"http://cf2.imgobject.com/t/p/w154%@",imageURL];
    [cell.videoThumbnail setImageWithURL:[NSURL URLWithString:thumbnailURL] placeholderImage:[UIImage imageNamed:@"icon"]];
    return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    DetailViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"boot"];
    [self.navigationController pushViewController:vc animated:YES];

}

假设你有一个像这样videoTitle在你的内部调用的属性DetailViewController

@property (nonatomic, strong) NSString *videoTitle;

然后你就这样做：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    DetailViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"boot"];
    vc.videoTitle = [[self.model.videos objectAtIndex:indexPath.row] objectForKey:@"title"];
    [self.navigationController pushViewController:vc animated:YES];
}

id video = [self.model.videos objectAtIndex:indexPath.row];
vc.title = [video objectForKey:@"title"];

顺便说一句，您不应该使用id上述类型video。
