openPhotoGallery and Titanium.Filesystem.getFile : Bug ?
Hey,
I try to select a picture with openPhotoGallery, and write with Titanium.Filesystem.getFile, after that i want to change the background of the windows…. It's work, but just the first time !
I check in / iphone simulator / user / …. / Documents /test.jpg at each change the image in the directory is good (!!), but not in the application (is always the first selected) ! As if he had a cache issue ….The background reload, but always with the same image (the first!).
When I reload the app, the image is the last selected (this confirm when I write with Filesystem it's work fine).
So…. It's very important for my app, please somebody can help me?
I use Titanium Developer 1.0 / SDK 1.0 and Iphone SDK : 3.1.3
Thank you

Before you write the test.jpg file, you should write a test to see if it 'exists' first, then delete it if it does.
Your code is probably not able to overwrite the first one.
hope this helps,

How do I delete test.jpg?
The second picture selected is saved in the cache of the application (see
/ iphone simulator / user / …. / Documents /test.jpg, after selecting the image, we can ensure that it's good)I had a reply on the old forum here :
http://support.appcelerator.net/discussions/support/2368-10-titaniumfilesystemgetfile-bugIf someone has an alternative to offer me ….
Thank you.
It's essential for my application, I can't finish because of this :( -
You can use this code for this.
var image = event,media; var filename = new Date().getTime() + "-app.jpg"; bgImage = Titanium.Filesystem.getFile(desigantionFile, filename); bgImage.write(image); -
Simply do a
bgImage.deleteFile();… at the end of your code…
