ios - Titanium scrollableView

Question

我在 Titanium 中开发应用程序。具有可 ScrollView 的代码。它在 Android 中工作但在 IOS 中不工作，并且不显示错误消息。代码:

exports.imagescroller = function(images, imgWidth, imgHeight){

var imageCollection = images;
var window = Ti.UI.createWindow({
    backgroundColor:'transparent',

});
if(imgWidth == null) {
    imgWidth = "100%";  
}

if(imgHeight == null) {
    imgHeight = "100%";
}

var scrollGallery = Ti.UI.createScrollableView({
    layout:'horizontal',
    showHorizontalScrollIndicator:true,
    showVerticalScrollIndicator:true,
});
var viewCollection = [];

for (var i = 0; i < imageCollection.length; i++) {
  var innerView = Ti.UI.createView({
    layout:'horizontal',
  });
  var item = Ti.UI.createImageView({
        width : imgWidth,
        height: imgHeight,
        imageID:i,
        defaultImage: imageCollection[0]
  });
  if (i < 3) {
    item.image = imageCollection[i];
  }

  innerView.add(item);
  viewCollection.push(innerView);
}

scrollGallery.addEventListener('scroll', function(e){
    if (scrollGallery.currentPage < (imageCollection.length-1)) {
        var nxt = scrollGallery.currentPage+1;
        scrollGallery.views[nxt].children[0].image = imageCollection[nxt];
    }
});
scrollGallery.views = viewCollection;

window.add(scrollGallery);
return window;

};

我在窗口中使用这个:

var Scroller = require("imagescroller");

window = Scroller.imagescroller(allData['images']);

请帮帮我!谢谢!

尝试使用更跨平台的scrollend事件:

scrollGallery.addEventListener('scrollend', function(e){
    .......
});

也可以尝试为您的 ScrollableView 指定明确的宽度和高度，以排除这种可能性:

var scrollGallery = Ti.UI.createScrollableView({
    layout:'horizontal',
    showHorizontalScrollIndicator:true,
    showVerticalScrollIndicator:true,
    width : "100%"
    height : "100%"
});
