小编Ant*_*ack的帖子

我正在使用此代码沿着曲线移动UIImage:

    // paint curve for sun
    let path = UIBezierPath()

    let imageSunName = "small_sun.png"
    let imageSun = UIImage(named: imageSunName)
    let imageView = UIImageView(image: imageSun!)

    imageView.frame = CGRect(x: xStart, y: yStart, width: 24, height: 24)
    self.view.addSubview(imageView)

    path.moveToPoint(CGPoint(x: xStart,y: yStart))

    path.addQuadCurveToPoint(CGPoint(x: xEnd, y: yEnd), controlPoint: CGPoint(x: xMiddleTop, y: yMiddleTop))

    let animation = CAKeyframeAnimation(keyPath: "position")
    animation.path = path.CGPath

    animation.repeatCount = 0
    animation.duration = 5.0

    imageView.layer.addAnimation(animation, forKey: "animate position along path")

尽管如此,还有两个问题:

• 我想仅沿路径部分移动图像(根据当前时间对日出/日落) - 如何做到这一点？
• 动画停止后,图像跳转到原点位置 - 我该怎样避免这种情况？

干杯

我正在使用ios-charts库.

我想将我的逆变器值分组,以便每年都是一组.不幸的是,每年每月的价值数量可能会有所不同.

我的数据json看起来像这样:

我尝试了以下方法:

var months = Array<String>()
var years = Array<String>()
var dataEntries: [BarChartDataEntry] = []
var dataSets: [BarChartDataSet] = []
var overallSum = 0.0
var year = 2010 //monthlyValues[0].year
var count = 0
var chartDataSet: BarChartDataSet?

for i in 0..<monthlyValues.count {
  // if year is different, create new barchartdataset
  if monthlyValues[i].year != year {
    years.append("\(monthlyValues[i].year)")
    chartDataSet = BarChartDataSet(yVals: dataEntries, label: "\(year)")
    chartDataSet!.colors = [UIColor.whiteColor()]
    dataSets.append(chartDataSet!)
    year = monthlyValues[i].year
    dataEntries = []
    //months = []
    count …

由于SAPUI5/OpenUI5中的图标集非常有限,我想在sap.ui.core.Icon中显示glyphicons和/或font-awesome图标.

怎么能实现这一目标？

我使用require.js加载我的模块,通常工作正常.不过,我确实有两个额外的问题:

1)如果你有一个类似帮助类的模块并为现有原型定义了其他方法(例如String.isNullOrEmpty),你会如何包含它们？您希望避免使用对模块的引用.

2)使用jQuery还需要改变什么.我知道需要jQuery,但是我还需要传递$吗？

谢谢!

我正在玩Knockout.js并创建了这个简单的例子:http://jsfiddle.net/JcTxT/30/

<div id="term_grp" data-role="fieldcontain"><a>Semester:</a>

<fieldset id="term_fields" data-role="controlgroup" data-type="horizontal">
    <input type="radio" name="term" id="ss" value="ss" data-bind="checked: term" />
    <label for="ss">Sommersemester</label>
    <input type="radio" name="term" id="ws" value="ws" data-bind="checked: term" />
    <label for="ws">Wintersemester</label>
</fieldset>
Term is <span data-bind="text: pommes"></span>

var aResult = {
    term: ko.observable("ss"),
    pommes: "TEST"
};

$(document).on('pagebeforeshow', '#mainPage', function () {
    ko.applyBindings(aResult);
});

我期望检查一个单选按钮(值为"ss"的那个)但事实并非如此.有谁知道,为什么？

干杯

我正在使用sap.m.Table来显示我的条目.用户可以删除列表项,在这种情况下,我想滚动到已删除列表项下方或上方的列表项,更新绑定.我通过调用indexOfItem来获取已删除列表项的位置,但是如何滚动到我不知道的位置.

任何的想法？

谢谢

我在我的混合(Cordova WebView)方法中使用OpenUI5.当下载最新的OpenUI5版本时,我最终得到了大量的文件,我不知道哪些是我的目的所必需的.似乎没有预编译文件包含移动/混合/任何方法所需的所有内容.

你们怎么解决这个问题？

谢谢,新年快乐!
