我对 swift & Xcode 还很陌生，我在 XCode 中使用了一个基本的“选项卡式”应用程序模板，我正在尝试实现 MBCalendarKit 以在第一个选项卡视图上显示日历。我正在为 MBCalendar 套件使用 Cocoapods。Basic 选项卡式应用程序从以下文件开始：
MBCalendarKit 的作者解释说：
“您可以显示 CKCalendarView 的实例。如果您想手动管理视图层次结构或更好地控制日历视图，请使用它。” ：
/*
Here's how you'd show a CKCalendarView from within a view controller.
It's just four easy steps.
*/
// 0. In either case, import CalendarKit:
#import "CalendarKit/CalendarKit.h"
// 1. Instantiate a CKCalendarView
CKCalendarView *calendar = [CKCalendarView new];
// 2. Optionally, set up the datasource and delegates
[calendar setDelegate:self];
[calendar setDataSource:self];
// 3. Present the calendar
[[self view] addSubview:calendar];
而且我还遵循了一些提供的示例代码，尽管其中大部分是在objective-c中。目前在运行程序时，在第一个选项卡视图上，我只是得到一个黑屏。如何解决此问题以显示日历本身？我还查看了 stackoverflow 上的其他 CalendarKit 帖子，但似乎没有一个可以解决像这样具体的问题。
我的 FirstViewController.swift （与作者提供的基本相同）：
import UIKit
import MBCalendarKit
class FirstViewController: CKCalendarViewController, CKCalendarViewDataSource {
var data : NSMutableDictionary
required init(coder aDecoder: NSCoder) {
data = NSMutableDictionary()
super.init(coder: aDecoder)
}
override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
self.data = NSMutableDictionary()
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
// Step 0 : Wire up the data source and delegate
self.delegate = self
self.dataSource = self
// Step 1 : Define some test events
let title : NSString = NSLocalizedString("Some random event", comment: "")
let date : NSDate = NSDate(day: 20, month: 12, year: 2015)
let event : CKCalendarEvent = CKCalendarEvent(title: title as String, andDate: date, andInfo: nil)
// Step 2 : Add the events to the cache array
self.data[date] = [event]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//
// MARK: - CKCalendarDataSource
//
func calendarView(calendarView: CKCalendarView!, eventsForDate date: NSDate!) -> [AnyObject]! {
return self.data.objectForKey(date) as! [AnyObject]!
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
和 AppDelegate.swift：
import UIKit
import MBCalendarKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
var viewController: CKCalendarViewController = FirstViewController(nibName: nil, bundle: nil)
self.window!.rootViewController = viewController
self.window!.makeKeyAndVisible()
return true
}
func applicationWillResignActive(application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
func applicationDidEnterBackground(application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(application: UIApplication) {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
此外，在 AppDelegate 文件中创建 FirstViewController() 时，我有点不确定 nibName 和 bundle 参数。如果有人可以解释这一点，因为我试图在 Apple 的参考文档中查找它，但它仍然不清楚，而且我知道我对两者都通过 nil 的事实可能是我的问题？如果有人有使用 CalendarKit 的经验或者可以帮助我，那就太好了，
干杯
