Question

我试图在touchmove事件发生时在Titanium iPhone应用程序中获取globalPoint，我使用以下代码获取globalPoint

var x = parseInt(e.globalPoint.x, 10);

它工作正常，直到我将Titanium 3.0.2 GA更新为3.1.0 GA，更新后我运行我遇到错误的应用程序

'undefined'不是对象（评估'eglobalPoint.x'）

我正在使用此代码来刷窗口

var animateLeft = Ti.UI.createAnimation({
    left : 250,
    curve : Ti.UI.ANIMATION_CURVE_EASE_OUT,
    duration : 150
});

var animateRight = Ti.UI.createAnimation({
    left : 0,
    curve : Ti.UI.ANIMATION_CURVE_EASE_OUT,
    duration : 150
});

var touchStartX = 0;
var touchStarted = false;

$.innerwin.addEventListener('touchstart', function(e) {
    touchStartX = parseInt(e.x, 10);
});

$.innerwin.addEventListener('touchend', function(e) {
    touchStarted = false;
    if ($.win.left >= 150) {
        $.win.animate(animateLeft);
        hasSlided = true;
    } else {
        $.win.animate(animateRight);
        hasSlided = false;
    }
});

$.innerwin.addEventListener('touchmove', function(e) {
    var x = parseInt(e.globalPoint.x, 10);
    var newLeft = x - touchStartX;
    if (touchStarted) {
        if (newLeft <= 250 && newLeft >= 0) {
            $.win.left = newLeft;
        }
    }
    if (newLeft > 30) {
        touchStarted = true;
    }
});

$.button.addEventListener('singletap', function(e) {
    $.toggleSlider();
});

var hasSlided = false;
exports.toggleSlider = function() {
    if (!hasSlided) {
        $.win.animate(animateLeft);
        hasSlided = true;
    } else {
        $.win.animate(animateRight);
        hasSlided = false;
    }
}

This has been deprecated:

相反，你需要这样做（在这个非常人为的例子中），并使用convertPointToView方法：

var baseview = Ti.UI.createView({width : Ti.UI.FILL, height : Ti.UI.FILL});
var view = Ti.UI.createView({ width : 20, height : 20 });
view.addEventListener('touchmove', function(e) {
    var globalPoint = convertPointToView({x : e.x, y : e.y}, baseview);
});
