嗨，我有一个非常基本的Titanium应用程序。有3个Web视图。当从一开始就有wifi时，所有三个Web视图都会正常加载。我检查了我的代码，只有在有互联网连接的情况下才会添加webview。如果没有，我添加标签说明连接到互联网和刷新按钮。当我单击刷新按钮时，添加Web视图会使应用程序崩溃。代码适用于iOS，而不是Android。使用SDK 3.2.3。代码如下：
refresh.addEventListener("click", function (e){
if(Ti.Network.online){
console.log(" here 1 -----------");
Navbar.remove(refresh);
console.log(" here 2 -----------");
self.remove(NoInternet_view);
console.log(" here 3 -----------");
self.add(shopWebView);
console.log(" here 4 -----------");
}
else{
alert("An internet connection is required");
}
});
日志到达打印输出＆＃34;这里3 ----------＆＃34;然后崩溃。

编辑：与地图页面关联的代码：
var removeRefresh = function removeRefresh() {
if(Ti.Network.getOnline()) {
console.log("issue 1-------");
self.remove(NoInternet_view);
console.log("issue 2-------");
self.add(map1);
console.log("issue 3-------");
Navbar.remove(refresh);
console.log("issue 4-------");
}
else alert("An internet connection is required");
};
refresh.addEventListener("click", removeRefresh);
答案 0 :(得分：1)
您正在匿名处理程序中销毁刷新（Ti.UI.Button）。
您可以尝试以下代码：
var removeRefresh = function removeRefresh() {
if(Ti.Network.getOnline()) {
Ti.API.info(" Checkpoint 1 -----------");
self.remove(NoInternet_view);
Ti.API.info(" Checkpoint 2 -----------");
self.add(shopWebView);
Ti.API.info(" Checkpoint 3 -----------");
Navbar.remove(refresh);
Ti.API.info(" Checkpoint 4 -----------");
}
else alert("An internet connection is required");
};
refresh.addEventListener("click", removeRefresh);
您必须确保存在NoInternet_view和shopWebView。
Titanium Studio Console将显示四条消息（Ti.API.info）
