Iphone 相机，钛金属加速器

Question

我正在使用 Titanium Appcelerator 创建一个 iPhone 应用程序。对于其中一个选项卡，我想包括一个相机。当我点击相机图像时，我希望应用：

• 打开相机拍照
• 询问用户是否想再拍一张照片
• 然后再打开摄像头就可以了
• （循环）
• 将图像（本地保存）放入数组中
• 返回按钮！

我似乎在任何地方都找不到相机功能。

Answer 1

此链接提供了一个简短的示例，但建议查看厨房水槽演示应用程序，厨房水槽几乎包含所有示例。

var win = Titanium.UI.createWindow({
    title:"Using the Camera and Video",
    backgroundColor:"#FFFFFF"
});

var button = Titanium.UI.createButton({
    title:"Use camera",
    width:180,
    height:48,
    bottom: 12,
    zIndex:2
});

button.addEventListener("click", function(e){
    //Open the photo gallery
    Titanium.Media.showCamera({
        //function to call upon successful load of the gallery
        success:function(e){
            if(e.mediaType === Titanium.Media.MEDIA_TYPE_PHOTO){
                //e.media represents the photo or video
                var imageView = Titanium.UI.createImageView({
                    image:e.media,
                    width:320,
                    height:480,
                    top:12,
                    zIndex:1
                });
                win.add(imageView);
            }else if(e.mediaType === Titanium.Media.MEDIA_TYPE_VIDEO){

                var w = Titanium.UI.createWindow({

                });

                w.add(videoPlayer);

                videoPlayer.addEventListener("complete", function(e){
                    w.remove(videoPlayer);
                    videoPlayer = null;
                    w.close();
                });

                w.open({modal:true});
            }

        },
        error:function(e){
            alert("There was an error");
        },
        cancel:function(e){
            alert("The event was cancelled");
        },
        //Allow editing of media before success

        videoQuality:Titanium.Media.QUALITY_HIGH
        /*other possible values for this property are
         * Titanium.Media.QUALITY_MEDIUM
         * Titanium.Media.QUALITY_LOW

    });
});

Titanium.App.addEventListener('camera_button', function(){
    Titanium.Media.takePicture();
});

win.add(button);

win.open();
