ios - Objective C TableView 清晰 Json 解析

Question

我有手动数据的工作项目，但我想在我的项目中添加 json 解析。我认为我需要帮助。 (必须是实时解析，如果可能的话，新的item添加时会自动释放)

我的 TableView 代码

- (void)scrollToLastTableViewCell {
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.uniqueCodes.count - 1
                                                inSection:0];
    [self.tableView scrollToRowAtIndexPath:indexPath
                          atScrollPosition:UITableViewScrollPositionTop
                                  animated:YES];
}



    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
    {
        return 15;
    }

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *cellid=@"CustomCell";
        CustomTableViewCell *cell=(CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellid];;


        if(cell==nil)
        {
            cell=[[CustomTableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellid];

        }
        cell.nameLabel.text=[NSString stringWithFormat:@"This is cell no %d of this table",indexPath.row+1];
        cell.cellButton1.tag=101+indexPath.row;
        cell.cellButton2.tag=201+indexPath.row;
        cell.cellButton3.tag=202+indexPath.row;
        cell.cellButton4.tag=203+indexPath.row;
        cell.cellButton5.tag=204+indexPath.row;
        cell.SwipableUIView.tag=301+indexPath.row;
     [cell setSelectionStyle:UITableViewCellSelectionStyleNone];


        return cell;
    }

CustomTableViewCell.h

@interface CustomTableViewCell : UITableViewCell

@property (weak, nonatomic) IBOutlet UILabel *nameLabel;
@property (weak, nonatomic) IBOutlet UIView *SwipableUIView;
@property (weak, nonatomic) IBOutlet UIButton *cellButton1;
@property (weak, nonatomic) IBOutlet UIButton *cellButton2;
@property (weak, nonatomic) IBOutlet UIButton *cellButton3;
@property (weak, nonatomic) IBOutlet UIButton *cellButton4;
@property (weak, nonatomic) IBOutlet UIButton *cellButton5;
@property (weak, nonatomic) IBOutlet UIButton *cellButton6;
@property (weak, nonatomic) IBOutlet UIButton *cellButton7;

@end

{

    "Items": [
        {
            "name": "My new name 1"
        },
        {
            "name": "My new name 2"
        },
        {
            "name": "My new name 3"
        }
    ]
}

谢谢你所做的一切。

您是否只是想从 JSON 中解析出唯一的代码，如下所示:

NSString *jsonString = /* Your JSON String Here */;
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *serializationError;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data
                                                     options:NSJSONReadingMutableContainers
                                                       error:&serializationError];
NSMutableArray *uniqueCodes = json[@"Items"];
