使用Swifty JSONparsing数组

这是我的JSONparsing（示例）： [ { "id": 1, "name": "Team name", "shower": { "id": 1, "status": 1, "startLocation": { "id": 1, "name": "abc 16" } } }, { "id": 2, "name": "Team name", "shower": { "id": 2, "status": 1, "startLocation": { "id": 1, "name": "efg 16" } } } ] 粘贴这个json查看器来轻松查看。 正如你所看到的，这是一个数组（团队）。 我需要让每个球队都做些什么。 经过多次尝试，我尝试使用SwiftyJSON ，因为我认为它会更容易。 但是，它没有为我工作。 这是我试过的： let […]

如何检查json对象的数组中的多个键相同的值？

我正在使用Swift3在日历上工作。 我知道可以为不同的键设置相同的值。 我有这个名为Dictionary of JSON objects的NSArray ： if parsedData["status"] as! Int == 200 { if let Streams = parsedData["data"] as! [AnyObject]? { for Stream in Streams { print(Stream) } Stream result: { "-" = 4; 1 = X; 10 = H; 11 = X; 12 = X; 13 = X; 14 = X; 15 = […]

RestKit – 与本地JSON文件同步数据库

我提供了一个示例JSON文件（用于testing目的，我没有提前访问Web服务）。 在加载文件和转换为NSDictionary ，我怎样才能使用该字典和同步我的数据库？ 我读过的所有教程和示例都使用了Web服务 我已经创build了所有对象的映射并应用它们的关系。 一个例子： + (RKEntityMapping *) mapTableInManagedObjectStore:(RKManagedObjectStore *)managedObjectStore { RKEntityMapping *tableMapping = [RKEntityMapping mappingForEntityForName:@"Table" inManagedObjectStore:managedObjectStore]; tableMapping.identificationAttributes = @[@"tableID"]; [tableMapping addAttributeMappingsFromDictionary:@{ @"ID":@"tableID", @"TableNumber":@"tableNumber", @"NumberOfChairs":@"numberOfChairs"}]; return tableMapping; }
