使用工廠函式進行聚合繫結

xmlView 中：

<mvc:View
    controllerName="sap.ui.demo.wt.controller.App"
    xmlns="sap.m"
    xmlns:mvc="sap.ui.core.mvc"
    displayBlock="true">
    <App>
        <pages>
            <Page content="{path:'Tiles>/Tiles',factory:'.tileFactory'}">
                
            </Page>
        </pages>
    </App>
</mvc:View>

控制器：

sap.ui.define([
    "sap/ui/core/mvc/Controller",
    "sap/ui/model/json/JSONModel"
], function (Controller, JSONModel) {
    "use strict";

    return Controller.extend("sap.ui.demo.wt.controller.App", {

        onInit: function(){
            var oModel  = new JSONModel("./model/data.json");
            
            this.getView().setModel(oModel,"Tiles");
        },
        tileFactory: function(sId,oContext){
            var oUIControl = null;
            
            var type = oContext.getProperty("type");
            
            switch(type){
                case "STD":
                    var title = oContext.getProperty("Title");
                    oUIControl = new sap.m.StandardTile();
                    
                    oUIControl.setTitle(title);
                    break;
                case "NEWS":
                    var title = oContext.getProperty("Title");
                    var newsContent = new sap.m.NewsContent({contentText:title});
                    oUIControl = new sap.m.GenericTile();
                    oUIControl.addTileContent(new sap.m.TileContent({content:newsContent}));
                    break;
                case "IMG":
                    var src = oContext.getProperty("src");
                    var imgContent = new sap.m.ImageContent({src});
                    oUIControl = new sap.m.GenericTile();
                    oUIControl.addTileContent(new sap.m.TileContent({content:imgContent}));
                    break;
            }
            
            return oUIControl;
        
        }
    });

});
