私はこの機能を持つビューコントローラを持っています：updateProgressComplete。しかし、私は、この関数がであるビューコントローラに値を追加することはできません他のコントローラからの関数への値の追加
私のビューコントローラを：私はこれが原因updateProgressCompleteで動作していないと思う
import UIKit
class StepsDetailViewController: UIViewController {
var pageIndex: Int! = 0
var titleText: String!
var stepData: String!
var pageControl: PageControl?
let screenSize: CGRect = UIScreen.mainScreen().bounds
@IBOutlet weak var dateLabel: UILabel!
@IBOutlet weak var stepsLabel: UILabel!
var g : ShapeView?
override func viewDidLoad(){
super.viewDidLoad()
self.dateLabel.text = self.titleText
self.stepsLabel.text = self.stepData
g = ShapeView(origin: CGPoint(x: UIScreen.mainScreen().bounds.width/2, y: UIScreen.mainScreen().bounds.height/2))
self.view.addSubview(g!)
}
func updateProgressComplete(newValue : CGFloat, view: StepsDetailViewController) {
self.dateLabel.text = "hello" <-- this doesn't work
}
}
は、別のクラスから来ている：
インポートUIKit
class PageControl: BasePageViewController, UIPageViewControllerDataSource {
var pageViewController: UIPageViewController!
var pageTitles: [[String]]!
var complete : CGFloat = 0.0;
var count = 0
override func viewDidLoad(){
super.viewDidLoad()
HealthKit().recentSteps() { steps, error in
self.pageTitles = steps;
self.count = self.pageTitles.count
self.count -= 1
self.pageViewController = self
self.pageViewController.dataSource = self
let startVC = self.viewControllerAtIndex(self.count) as StepsDetailViewController
let viewControllers = NSArray(object: startVC)
print(viewControllers)
dispatch_async(dispatch_get_main_queue(), {
self.pageViewController.setViewControllers(viewControllers as? [UIViewController], direction: .Forward, animated: true, completion: nil)
})
}
}
override func percentCompleteDidChange() {
if let percentComplete = self.percentComplete {
complete = percentComplete
let vc: StepsDetailViewController = self.storyboard?.instantiateViewControllerWithIdentifier("StepsDetailViewController") as! StepsDetailViewController
vc.updateProgressComplete(percentComplete, view: vc)
}
}
func viewControllerAtIndex(index: Int) -> StepsDetailViewController
{
if ((self.pageTitles.count == 0) || (index >= self.pageTitles.count)) {
return StepsDetailViewController()
}
let vc: StepsDetailViewController = self.storyboard?.instantiateViewControllerWithIdentifier("StepsDetailViewController") as! StepsDetailViewController
vc.titleText = self.pageTitles[index][0]
vc.stepData = self.pageTitles[index][1]
vc.pageIndex = index
return vc
}
// MARK: - Page View Controller Data Source
func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController?
{
let vc = viewController as! StepsDetailViewController
var index = vc.pageIndex as Int
if (index == 0 || index == NSNotFound)
{
return nil
}
index -= 1
return self.viewControllerAtIndex(index)
}
func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
let vc = viewController as! StepsDetailViewController
var index = vc.pageIndex as Int
if (index == NSNotFound){
return nil
}
index += 1
if (index == self.pageTitles.count)
{
return nil
}
return self.viewControllerAtIndex(index)
}
}
どうすればこの問題を解決できますか？私はそれが私がこれを使用する何かを持っていると思う：instantiateViewControllerWithIdentifier？ updateProgressCompleteの値は常に変更されるため、その関数を使用し、変数として渡さないようにします。
