我有一个实现UISearchBarDelegate的UITableVIewController,视图嵌入在导航控制器中.

    class FacilityTableViewController: UITableViewController, UISearchResultsUpdating, UISearchBarDelegate, AmenityFilterDelegate {

        // MARK: - Public Variables

        var targetFacilities = [Int]()
        var searchController: UISearchController = UISearchController(searchResultsController: nil)

        // MARK: - Private Variables

        private var viewModel: FacilityTableViewModel!
        private let parkGreenColor = UIColor(red: 73/255, green: 136/255, blue: 84/255, alpha: 1)
        private var showEmptyMessage = false

        // MARK: - View Lifecycle

        /**
        Setup view after loading
        */
        override func viewDidLoad() {
            super.viewDidLoad()

            trackScreenView("Facility Table View")

            if targetFacilities.isEmpty {
                viewModel = FacilityTableViewModel()
            } else {
                viewModel = FacilityTableViewModel(facilityIds: …

我有一个Cocoa Touch Framework,我开发用于我的iOS应用程序和iOS 8上的WatchKit应用程序.我对iOS 8没有任何问题,但是当我将项目移动到iOS 9并更新WatchKit应用程序本机运行时我得到以下错误:

ParkFinderKit was rejected as an implicit dependency for 'ParkFinderKit.framework' because it doesn't contain platform 'watchsimulator' in its SUPPORTED_PLATFORMS 'iphonesimulator, iphoneos'

我尝试手动将watchossimulator和watchos添加到支持的平台列表中:

但是这会产生另一个错误:

ParkFinderKit was rejected as an implicit dependency for 'ParkFinderKit.framework' because its SDK is platform 'com.apple.platform.iphonesimulator' and it needs to match platform 'com.apple.platform.watchsimulator'

关于如何解决我的问题的任何想法？

我试图使用Json.NET从Web服务解析JSON，该Web服务以以下格式返回数据：

{
    "0": {
        "ID": 193,
        "Title": "Title 193",
        "Description": "Description 193",
        "Order": 5,
        "Hyperlink": "http://someurl.com"
    },
    "1": {
        "ID": 228,
        "Title": "Title 228",
        "Description": "Description 228",
        "Order": 4,
        "Hyperlink": "http://someurl.com"
    },
    "2": {
        "ID": 234,
        "Title": "Title 234",
        "Description": "Description 234",
        "Order": 3,
        "Hyperlink": "http://someurl.com"
    }
}

我使用json2sharp从JSON生成一个类：

public class __invalid_type__0
{
    public int ID { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public int Order { …
