Question

我正在尝试使用Thymeleaf从模板内的语言文件中迭代分裂的字符串。但它不起作用。

模板样本：

import UIKit
import SpriteKit
import iAd
import GoogleMobileAds

class GameViewController: UIViewController, ADBannerViewDelegate {

var SH = UIScreen.mainScreen().bounds.height
let transition = SKTransition.fadeWithDuration(1)
var UIiAd: ADBannerView = ADBannerView()
var googleBannerView: GADBannerView!

override func viewWillAppear(animated: Bool) {
    /*  var BV = UIiAd.bounds.height
    UIiAd.delegate = self
    UIiAd.frame = CGRectMake(0, SH + BV, 0, 0)
    self.view.addSubview(UIiAd) */

    UIiAd.setTranslatesAutoresizingMaskIntoConstraints(false)
    UIiAd.delegate = self
    self.view.addSubview(UIiAd)
    let viewsDictionary = ["bannerView":UIiAd]
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[bannerView]|", options: .allZeros, metrics: nil, views: viewsDictionary))
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[bannerView]|", options: .allZeros, metrics: nil, views: viewsDictionary))

}

override func viewWillDisappear(animated: Bool) {
    UIiAd.delegate = nil
    UIiAd.removeFromSuperview()
}

func bannerViewDidLoadAd(banner: ADBannerView!) {

    var BV = UIiAd.bounds.height
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.alpha = 1 // Fade in the animation
    UIView.commitAnimations()

    println("iAd work")
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1)
    UIiAd.alpha = 0
    UIView.commitAnimations()

    googleBannerView = GADBannerView(adSize: kGADAdSizeSmartBannerLandscape)
    googleBannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
    googleBannerView.rootViewController = self
    var request: GADRequest = GADRequest()
    googleBannerView.loadRequest(request)

    googleBannerView.frame = CGRectMake(0, view.bounds.height - googleBannerView.frame.size.height, googleBannerView.frame.size.width, googleBannerView.frame.size.height)

    self.view.addSubview(googleBannerView!)

    println("iAd fail")
}

func showBannerAd() {
    UIiAd.hidden = false
    var BV = UIiAd.bounds.height

    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.frame = CGRectMake(0, SH - BV, 2048, 0) // End position of the animation
    UIView.commitAnimations()

}

func hideBannerAd() {
    UIiAd.hidden = true
    var BV = UIiAd.bounds.height

    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1) // Time it takes the animation to complete
    UIiAd.frame = CGRectMake(0, SH + BV, 0, 0) // End position of the animation
    UIView.commitAnimations()
}

override func viewDidLoad() {
    super.viewDidLoad()
    self.UIiAd.hidden = true
    self.UIiAd.alpha = 0

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "hideBannerAd", name: "hideadsID", object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "showBannerAd", name: "showadsID", object: nil)

    let scene = GameScene(size: CGSize(width: 2048, height: 1356))
    let skView = self.view as! SKView
    skView.showsFPS = true
    skView.showsNodeCount = true
    skView.ignoresSiblingOrder = true
    scene.scaleMode = SKSceneScaleMode.AspectFill
    skView.presentScene(scene)
}

func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {

    println("Clicked")
    //  let skView: SKView = self.view as! SKView
    //  skView.scene!.paused = true
    return true
}
/*    func bannerViewActionDidFinish(banner: ADBannerView!) {
let skView: SKView = self.view as! SKView
skView.scene!.paused = false
} */

override func prefersStatusBarHidden() -> Bool {
    return true
}

语言文件<div class="row" th:with="SPlatform=#{platforms}"> <div class="input-field col s4" th:each="platform : ${#strings.arraySplit(SPlatform, ',')}"> <input type="checkbox" class="filled-in" th:id="platforms"> <label th:for="platforms" th:text=""></label> </div> </div>中#{platforms}的值为

messages_en.properties

但最后我得到了这个错误：

platforms=Platform1,Platform2,Platform3

Answer 1

问题可能是

th:text=""

在你的标签内。

Thymeleaf希望表达式显示一些文字。

Thymeleaf模板中的迭代不起作用
