how to save UIImagePicker image with a specific name

Question

i capture image from iphone using UIPickerController, then how programatically to save it with specific name, and to call the image later (by using the name), is it any possibil

Answer 1

The following code snippet will save the image to a file:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *anImage = [info valueForKey:UIImagePickerControllerOriginalImage];
    NSData *imageData = UIImageJPEGRepresentation(anImage, 1.0);
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [paths objectAtIndex:0];
    NSString *tmpPathToFile = [[NSString alloc] initWithString:[NSString stringWithFormat:@"%@/specificImagedName.jpg", path]];

    if([imageData writeToFile:tmpPathToFile atomically:YES]){
          //Write was successful. 
    }
}

And then to recall the image from a file:

NSData *imageData = [NSData dataWithContentsOfFile:tmpPathToFile];
[UIImage imageWithData:imageData];

Finally, this post has a method available that you can incorporate into your project to resize the image.
