钛将照片添加到特定的画廊

Question

So I have the following which works real nice as is:

 button.addEventListener("click", function(e){
    Titanium.Media.showCamera({
        success:function(e){
            if(e.mediaType === Titanium.Media.MEDIA_TYPE_PHOTO){
                var imageView = Titanium.UI.createImageView({
                    image: e.media,
                    width: 'auto',
                    height: 'auto',
                    top: 50,
                    zIndex: 1
                });
                win.add(imageView);
            } else {
                alert("Only Photos aloud");
            }
        },
        error:function(e){
            alert("There was an error");
        },
        cancel:function(e){
            alert("The event was cancelled");
        },
        allowEditing: true,
        saveToPhotoGallery: true,
        mediaTypes:[Titanium.Media.MEDIA_TYPE_PHOTO,Titanium.Media.MEDIA_TYPE_VIDEO],
        videoQuality:Titanium.Media.QUALITY_HIGH
    }); 
});

saveToPhotoGallery just adds the taken photo to the default gallery in the iOS Photos App. I need to add the photo to a specific folder in the iOS Photos App though. Has anyone an idea how I could do this from with Titanium ? I have been searching the intewebs but have not found anything on how to add a taken photo to a specific folder.

Thank for the help guys

Answer 1

But, let me specify that the file can be save in the Application Directory only in IOS but in android you can save it in the externalStorage. You can have look at the documentation through the below link :

https://docs.appcelerator.com/platform/latest/#!/guide/Filesystem_Access_and_Storage

You can easily save the file to your folder using the following code :

if (OS_ANDROID) {
    var f12 = Titanium.Filesystem.getFile(Titanium.Filesystem.externalStorageDirectory);
} else {
    var f12 = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory);
}

var galleryImg = e.media;
var fileToSave = null;
var fileName = 'IMG' + todayDate + "HB" + Ti.App.Properties.getInt('imgCounter') + '.jpg';
if (OS_ANDROID) {
    fileToSave = Titanium.Filesystem.getFile(f12.resolve(), fileName);
} else {
    fileToSave = Titanium.Filesystem.getFile(f12.resolve(), fileName);
}
fileToSave.write(galleryImg);

If you want to create a subDirectory then use the following code :

var dir = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory,'mysubdir');
dir.createDirectory(); // this creates the directory

EDIT

You Could do it this way :

// get the TiBlob 
var blob = img_view.toImage();

// try to save the image the image
Ti.Media.saveToPhotoGallery(blob,{
    success: function(e){
        if (callback == undefined) {
           alert('Saved image to gallery');
        } else {
           callback();
        }
    },
    error: function(e){
        alert("Error saving the image");
    }
});

Good Luck, Cheers
