Question

我正在使用JSONModel开发一个ios应用程序，但我的RootTabeViewController没有显示我使用过JSONModel的任何数据。你可以在github上看到我的项目：

https://github.com/ShahriatHossain/myprojectios

，这是我的JSON数据格式：

[
{
    "businessID": 1,
    "name": "Favorite BC"
},
{
    "businessID": 2,
    "name": "Related to me"
},
{
    "businessID": 3,
    "name": "Reported by me"
},
{
    "businessID": 4,
    "name": "Ready for approval"
},
{
    "businessID": 5,
    "name": "Approved BC"
}

这是我的BusinessModel.h代码

#import "JSONModel.h"

@protocol BusinessModel @end

@interface BusinessModel : JSONModel

@property (assign, nonatomic) int businessID;
@property (strong, nonatomic) NSString* name;

@end

，这是我的BusinessManager.h代码

#import "JSONModel.h"
#import "BusinessModel.h"

@interface BusinessManager : JSONModel
@property (strong, nonatomic) NSArray<BusinessModel>* businesses;
@end

，这是我的RootTableViewController.m代码

#import "RootTableViewController.h"
#import "SecondTableViewController.h"

#import "JSONModelLib.h"
#import "BusinessManager.h"
#import "HUD.h"

@interface RootTableViewController (){
    BusinessManager* _businessFeeds;
}
@end

@implementation RootTableViewController


- (void)viewDidLoad {
    [super viewDidLoad];

    //businesses = [NSArray arrayWithObjects:@"Favorite BC",@"Related to me",@"Reported by me", @"Ready for approval",@"Approved BC", nil];

    //show loader view
    [HUD showUIBlockingIndicatorWithText:@"Fetching JSON"];

    //fetch the feed
    _businessFeeds = [[BusinessManager alloc] initFromURLWithString:@"http://localhost:8888/json/business.json"
                                         completion:^(JSONModel *model, JSONModelError *err) {
             //hide the loader view
             HUD hideUIBlockingIndicator];

             //json fetched
             NSLog(@"loans: %@", _businessFeeds.businesses);
            [self.tableView reloadData];

             }];

}

    // Configure the cell...
    if(cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }
    cell.textLabel.text = [NSString stringWithFormat:@"%@", business.name];
    return cell;

#pragma mark - Navigation

    if([segue.identifier isEqualToString:@"arrayDetail"])
    {

        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];

        BusinessModel* business = _businessFeeds.businesses[indexPath.row];


        SecondTableViewController *destViewController = segue.destinationViewController;

        destViewController.businessName = [NSString stringWithFormat:@"%@", business.name];

        destViewController.title = destViewController.businessName;

    }
}


@end

我在代码中做错了什么我不知道。我是ios app开发的新手。

有人能帮助我吗？

我在这里做错了是错误的json格式，这里是正确的：

{＆＃34;商家＆＃34;：[ { ＆＃34; businessID＆＃34;：1，＆＃34;姓名＆＃34;：＆＃34;最喜欢的BC＆＃34; }， { ＆＃34; businessID＆＃34;：2，＆＃34;姓名＆＃34;：＆＃34;与我相关＆＃34; }， { ＆＃34; businessID＆＃34;：3，＆＃34;姓名＆＃34;：＆＃34;由我报告＆＃34; }， { ＆＃34; businessID＆＃34;：4，＆＃34;名称＆＃34;：＆＃34;准备好批准＆＃34; }， { ＆＃34; businessID＆＃34;：5，＆＃34;姓名＆＃34;：＆＃34;批准BC＆＃34; } ]}

我的应用正在加载json数据。

使用JSONModel时，TableViewController上没有显示Json数据
