Hi, am new to iPhone and i have been given a task to show all the images from the gallery of the iPhone to the current view so that the user can select an image and view it and here's the second part of my problem i am having a share button and its functionality is that the selected image by the user on the touch of the share button must be shared on facebook.
Please help me regarding this,
To select image from photo library use UIImagePickerController, here's an example: http://www.zimbio.com/iPhone/articles/1109/Picking+Images+iPhone+SDK+UIImagePickerController
To integrate facebook in your app, you'll use facebook ios sdk: http://github.com/facebook/facebook-ios-sdk
Edit 1:
Ok, here's the link for uiimagepickercontrollerdelegate whose method you'll use to get the image, it's really not that hard: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerControllerDelegate_Protocol/UIImagePickerControllerDelegate/UIImagePickerControllerDelegate.html%23//apple_ref/doc/uid/TP40007069
Here's the demo for facebook connect: link text
