ios - 如何将JSON放入NSMutableArray

Question

嗨，我是iOS开发的新手，目前在开发计划 Activity 时遇到问题

请让我知道如何添加JSON数据而不是硬编码数组。我只需要将json中的customer_name，customer_id替换为该硬编码数据

这是我的日程表按钮单击事件:

- (IBAction)schedule:(id)sender {

    FFCalendarViewController *rootController = [FFCalendarViewController new];
    [rootController setArrayWithEvents:[self arrayWithEvents]];


      [self.navigationController pushViewController:rootController animated:YES];


}

这是我的硬编码数组:

- (NSMutableArray *)arrayWithEvents {

    FFEvent *event1 = [FFEvent new];
    [event1 setStringCustomerName: @"Customer A"];
    [event1 setNumCustomerID:@1];
    [event1 setDateDay:[NSDate dateWithYear:[NSDate componentsOfCurrentDate].year month:[NSDate componentsOfCurrentDate].month day:[NSDate componentsOfCurrentDate].day]];
    [event1 setDateTimeBegin:[NSDate dateWithHour:10 min:00]];
    [event1 setDateTimeEnd:[NSDate dateWithHour:15 min:13]];


    FFEvent *event2 = [FFEvent new];
    [event2 setStringCustomerName: @"Customer B"];
    [event2 setNumCustomerID:@2];
    [event2 setDateDay:[NSDate dateWithYear:[NSDate componentsOfCurrentDate].year month:[NSDate componentsOfCurrentDate].month day:[NSDate componentsOfCurrentDate].day]];
    [event2 setDateTimeBegin:[NSDate dateWithHour:9 min:15]];
    [event2 setDateTimeEnd:[NSDate dateWithHour:12 min:138]];

   return [NSMutableArray arrayWithArray:@[event1, event2]]; 

}

这是我的json输出，我想替换为硬编码数组:

[  
   {  
      "customer_id":"802",
      "customer_name":"Tela"

   },
   {  
      "customer_id":"803",
      "customer_name":"Bena"
   }
]

这是我的序列化JSON代码:

NSData *myData = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];

NSMutableArray  *testFeeds = [NSJSONSerialization JSONObjectWithData: myData options:NSJSONReadingMutableContainers error:nil];

     NSMutableArray   *rec = [[NSMutableArray alloc] init];

        [rec addObjectsFromArray:testFeeds];

请帮助我解决此问题。

使用以下代码序列化json

NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e];

现在 jsonArray包含 json文件的可变数据。因此，您可以在此数组中直接更改或更新值。

编辑

NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e];

NSMutableArray   *rec = [[NSMutableArray alloc] init];

for (int i = 0; i< jsonArray.count; i++) {
    FFEvent *event1 = [FFEvent new];
    [event1 setStringCustomerName:jsonArray[i][@"customer_name"]];
    [event1 setNumCustomerID:[jsonArray[i][@"customer_id"] integerValue]];
    [event1 setDateDay:[NSDate dateWithYear:[NSDate componentsOfCurrentDate].year month:[NSDate componentsOfCurrentDate].month day:[NSDate componentsOfCurrentDate].day]];
    [event1 setDateTimeBegin:[NSDate dateWithHour:10 min:00]];
    [event1 setDateTimeEnd:[NSDate dateWithHour:15 min:13]];

    [rec addObject:event1];
}
