Question

我目前正在开展一个项目，我必须将图像保存到照片库，并为每个捕获的图像指定一个名称。我知道如何保存图像，但是如何为保存在库中的图像指定名称？

我的代码：

-(void)imagePickerController:(UIImagePickerController *) picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{   
    [picker dismissModalViewControllerAnimated:YES];
    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
     imgglobal =imageView.image;    


    //for saving image in photo library
    UIGraphicsBeginImageContext(self.imageView.bounds.size);


    [self.imageView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage =   UIGraphicsGetImageFromCurrentImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);
    UIGraphicsEndImageContext();
    UIImage *image1=imageView.image;
    [self imageSavedToPhotosAlbum:image1 didFinishSavingWithError:nil contextInfo:nil];          
} 

- (void)imageSavedToPhotosAlbum:(UIImage *)image  didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { 
        NSString *message;
        NSString *title;
        if (!error) {
            title = NSLocalizedString(@"SaveSuccessTitle", @"");
            message = NSLocalizedString(@"SaveSuccessMessage", @"");
        } else {
            title = NSLocalizedString(@"SaveFailedTitle", @"");
            message = [error description];
        }
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                              message:message
                                              delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"OK", @"")
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
}

照片库中的照片不包含任何名称。而且您也无法在照片库中创建文件夹。如果您确实需要照片的名称，请将其放在~/Documents内并实施您自己的选择器。

如何为照片库中保存的照片指定名称？
