Uploading image issue (UIImageJPEGRepresentation vs UIImagePNGRepresentation)

Question

I have stored a few pictures using Safari\'s \"Hold + Save Image\" option to my Photo Library in simulator. When I pick an image from the library, I have to convert it to JPEG o

Answer 1

Regarding your third point, you can determine the image type loaded from the library in your image picker delegate method as follows:

- (void)imagePickerController:(UIImagePickerController *)picker 
didFinishPickingMediaWithInfo:(NSDictionary *)info {

    // Get the image reference URL
    NSURL *referenceURL = [info objectForKey:UIImagePickerControllerReferenceURL];

    // The path extension contains the image type: JPG, PNG, GIF, etc.
    NSString *originalImageType = referenceURL.pathExtension; 

}
