Hi all,
I am developing an aplication where i need the information about image like size,date of creation,type(.jpg/png).I am picking image using UIImagePickerController. Is there any methods used to get this.

When you get access to an image from the UIImagePickerController you have none of that info. You don't have access to a file. The image data has been converted to an internal bitmap format that is neither PNG nor JPEG. All you have is raw pixel data. No EXIF info, nothing.

Hi thanx for replying
Is there any way to do this. Actually my application taking image using
UIImagePickerControllerSourceTypeSavedPhotosAlbum. Then i am clicking on any image and it is loaded on window in full size. On window i am using nav barand button .I want on button click it shows info on table view.

What part of "No EXIF info, nothing" was difficult to understand?

All you get are the image dimensions.

I understand that you're saying it's impossible, but how do I do it?

I like your attitude... Jailbroken devices are your only playing ground for that.

Hi
If i can not do this then i must stop working on this application.

can it possible that i just download image from iPhone hard drive and saved it on view in group and get information using file manager.

can you maybe reformulate your question? It is difficult to understand what you want.

Look into the NSFileManager documentation and see which file properties are available.
