我的窗口关闭代码

SubCategoryWindow.addEventListener('android:back', _androidBack);
function _androidBack(e) {
    bottomAdvertisementInterval = null;
    categoryId = null;
    SubCategoryWindow.removeEventListener('android:back', _androidBack);
    SubCategoryWindow.hide();
    SubCategoryWindow = null;
    LoadingIndicator = null;
    itemId = null;
    ImageCacheModule = null;
    fbShareBlob = null;
}

Answer 1

iOS 设备上没有返回按钮，也没有这样的事件监听器。在此处阅读更多详细信息：http://docs.appcelerator.com/titanium/latest/#!/api/Titanium.UI.Window-event-androidback

如果您要部署跨平台应用程序，您应该实现 branching code。

如果在更正代码后崩溃仍然存在，请发布有问题的源代码以帮助您解决崩溃问题。
