这种情况非常随机，有时是打开第一个窗口，有时是9个或更多。
从Titanium 3.1升级到3.2后，我发现了这个错误，其中NavigationGroup被NavigationWindow取代。
以下其中一个堆栈跟踪显示：

打开新窗口时执行的功能：
var openingView = false;
Alloy.Globals.open = function(name, args) {
var view;
args = args || {};
if (typeof name === 'string') {
view = Alloy.createController(name, args).getView();
} else if (name.getView) {
view = name.getView();
name = view.id;
}
if (openingView === false) {
openingView = true;
view.addEventListener('focus', function viewFocus(event) {
openingView = false;
view.removeEventListener('focus', viewFocus);
});
if (view) {
if (view.loading) {
view.addEventListener('loaded', function onLoaded() {
Alloy.Globals.nav.openWindow(view);
view.removeEventListener('loaded', onLoaded);
});
} else {
Alloy.Globals.nav.openWindow(view);
}
}
}
};
答案 0 :(得分：0)
很难说没有看到导致崩溃的JS代码，但似乎你试图在数组外部或者在null中访问和对象： - [__ NSArrayM objectAtIndex：]：索引4超出边界[0 .. 1]
尝试在发现崩溃的地方发布代码。
