手柄LocalNotification点击

Question

在我的钛iOS应用程序中，我使用以下代码显示一个LocalMessage：

Ti.App.iOS.scheduleLocalNotification({
    alertBody:"New Notification!",
    userInfo: {id:1234}
});

但是，现在我无法了解如何在用户点击此通知时执行代码。我试过以下几种方法：

Ti.App.iOS.addEventListener("localnotificationaction",function(){
    //my code
});

但是代码不会以这种方式执行。我也试过监听“通知”-event，但没有成功。

这是如何正确完成的呢？

我认为你应该用：

// listen for a local notification event
Ti.App.iOS.addEventListener('notification',function(e)
{
    Ti.API.info("local notification received: "+JSON.stringify(e));
});

如docs中所指定的：http://docs.appcelerator.com/titanium/3.0/#!/api/Titanium.App.iOS-event-notification

看看这里的完整例子：https://jira.appcelerator.org/browse/TIMOB-18182 Maby你错过了一个步骤吗？

创建一个新项目并尝试如下：

index.js：

    var win = Ti.UI.createWindow({
        backgroundColor:'white'
    });
    win.open();
    var label = Ti.UI.createLabel({
        top: 20,
        height: 200,
        width: 200,
        text: "Background the app"
    });
    win.add(label);

    function isiOS4Plus()
    {
        // add iphone specific tests
        if (Titanium.Platform.name == 'iPhone OS')
        {
            var version = Titanium.Platform.version.split(".");
            var major = parseInt(version[0],10);

            // can only test this support on a 3.2+ device
            if (major >= 4)
            {
                return true;
            }
        }
        return false;
    }

    if (isiOS4Plus())
    {
        // register a background service. this JS will run when the app is backgrounded but screen is OFF!!!
        var service = Ti.App.iOS.registerBackgroundService({url:'bg.js'});

        Ti.API.info("registered background service = "+service);

        // listen for a local notification event
        Ti.App.iOS.addEventListener('notification',function(e)
        {
            Ti.API.info("local notification received: "+JSON.stringify(e));
        });

        // fired when an app resumes for suspension
        Ti.App.addEventListener('resume',function(e){
            Ti.API.info("app is resuming from the background");
        });
        Ti.App.addEventListener('resumed',function(e){
            Ti.API.info("app has resumed from the background");
        });

        //This event determines that the app it was just paused
        Ti.App.addEventListener('pause',function(e){
            Ti.API.info("app was paused from the foreground");
        });
    }

bg.js：

    var value = "Hello from Running BG service - bg.js";
    Ti.API.info(value);

    var notification = Ti.App.iOS.scheduleLocalNotification({
        alertBody:"App was put in background",
        alertAction:"Re-Launch!",
        userInfo:{"hello":"world"},
        date:new Date(new Date().getTime() + 3000) // 3 seconds after backgrounding
    });

    Ti.App.iOS.addEventListener('notification',function(){
        Ti.API.info('background event received = '+notification);
        //Ti.App.currentService.unregister();
    });

使用此应用程序在日志上输出：

[INFO] :   registered background service = [object TiAppiOSBackgroundService]
[INFO] :   app was paused from the foreground
[INFO] :   Hello from Running BG service - bg.js

-在我点击横幅之后

[INFO] :   app is resuming from the background
[INFO] :   local notification received: {"sound":null,"alertBody":"App was put in background","alertAction":"Re-Launch!","date":"2014-12-12T12:52:34.743Z","alertLaunchImage":null,"timezone":"America/Los_Angeles","badge":0,"userInfo":{"hello":"world"},"bubbles":true,"type":"notification","source":{},"cancelBubble":false}
[INFO] :   background event received = [object TiAppiOSLocalNotification]
[INFO] :   app has resumed from the background
