appcelerator createwindow使整扇窗户变黑

Question

我正在使用钛来开发一个iOS应用程序。我有一个主窗口，我需要在上面打开一个模态窗口。我在模态窗口(附加代码)上设置了一个textArea和两个按钮，用于保存和取消。

问题是当我打开窗户的时候，整个窗户都变黑了。

我做错什么了？谢谢..。

addEvenButton.addEventListener('click', function() {
    var eventDesc = '';
    var t = Titanium.UI.create2DMatrix();
    t = t.scale(0);

    var noteWin = Titanium.UI.createWindow({
        backgroundColor : '#b4be00',
        borderWidth : 8,
        borderColor : '#999',
        height : 460,
        width : 325,
        borderRadius : 10,
        opacity : 0.92,
        modal: true,
        transform : t
    });

    // create first transform to go beyond normal size
    var t1 = Titanium.UI.create2DMatrix();
    t1 = t1.scale(1.1);
    var a = Titanium.UI.createAnimation();
    a.transform = t1;
    a.duration = 1000;

    // when this animation completes, scale to normal size
    a.addEventListener('complete', function() {
        var t2 = Titanium.UI.create2DMatrix();
        t2 = t2.scale(1.0);
        noteWin.animate({
            transform : t2,
            duration : 200
        });

    });
    var noteField = Titanium.UI.createTextArea({
        color : 'black',
        hintText : 'Enter text description here',
        suppressReturn:false,
        height : 200,
        top : 100,
        width : 250,
        keyboardType : Titanium.UI.KEYBOARD_NAMEPHONE_PAD,
        returnKeyType : Titanium.UI.RETURNKEY_DEFAULT,
        borderStyle : Titanium.UI.INPUT_BORDERSTYLE_ROUNDED
    });

    // create a button to close window
    var closeButton = Titanium.UI.createButton({
        title : 'Save text',
        height : 40,
        left : 40,
        top : 50,
        width : 100
    });

    // create a button to close window
    var cancelButton = Titanium.UI.createButton({
        title : 'Cancel',
        height : 40,
        left : 180,
        top : 50,
        width : 100
    });

    noteWin.add(noteField);
    noteWin.add(closeButton);
    noteWin.add(cancelButton);

    closeButton.addEventListener('click', function() {
        var t3 = Titanium.UI.create2DMatrix();
        t3 = t3.scale(0);
        noteWin.close({
            transform : t3,
            duration : 300
        });
        addEvent('Event', noteField.value);
    });

    cancelButton.addEventListener('click', function() {
        var t3 = Titanium.UI.create2DMatrix();
        t3 = t3.scale(0);
        noteWin.close({
            transform : t3,
            duration : 300
        });
    });

    noteWin.addEventListener('singletap', function(e) {
        noteField.blur();
    });
    noteWin.addEventListener('open', function(e) {
        noteField.focus();
    });

    noteWin.open(a);
});

尝试将"zIndex:1000"属性添加到模态窗口，以确保它不会被另一个模式窗口隐藏。
