你需要使用这样的东西

- (IBAction)selectPhotos
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.delegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

- (void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingImage:(UIImage *)image
                  editingInfo:(NSDictionary *)editingInfo
{
    imageView.image = image;
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];
}


- (IBAction)saveImage:(id)sender {
    if(imageView.image) {
        [self showProgressIndicator:@"Saving"];
        UIImageWriteToSavedPhotosAlbum(imageView.image, self, @selector(finishUIImageWriteToSavedPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
    }
}
