ios - 在 iPhone 中创建自定义图片库

Question

我已经使用下面的代码从图库或直接使用相机中挑选照片

- (void)actionSheet:(UIActionSheet *)actionSheet 
         clickedButtonAtIndex:(NSInteger)buttonIndex {

    UIImagePickerController *imagePickerController = 
      [[UIImagePickerController alloc]init];

    imagePickerController.delegate = self;
    if (buttonIndex == 0) {
        photoButtonNum=0;
        [self presentViewController:imagePickerController 
                           animated:YES 
                         completion:nil];
        imagePickerController.sourceType =  
          UIImagePickerControllerSourceTypePhotoLibrary;
    } else if (buttonIndex == 1) {
        photoButtonNum=1;
        [self presentViewController:imagePickerController 
                           animated:YES 
                         completion:nil];
        imagePickerController.sourceType =  
          UIImagePickerControllerSourceTypeCamera;
    }
}

我正在寻找创建我自己的应用程序的自定义目录(文件夹)以将挑选的照片保存在 iPhone 中。我需要你的帮助

1. 为我自己的应用创建自定义目录
2. 想要将选择的照片保存在该自定义目录中。

我是 iPhone 开发的新手，期待您的宝贵帮助。提前致谢。

本站有助于您创建和保存Photo in your Directory

你也可以使用下面的代码。

- (void)imagePickerController:(UIImagePickerController *)picker 
          didFinishPickingMediaWithInfo:(NSDictionary *)info {
     UIImage *pickedImage = 
       [info objectForKey:UIImagePickerControllerOriginalImage];
     NSData *imageData = UIImagePNGRepresentation(pickedImage);

     NSString *documentsDirectory = 
       [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
                                            NSUserDomainMask, 
                                            YES) lastObject];
     NSString *path = [documentsDirectory 
       stringByAppendingPathComponent:@"imageName.png"];

    NSError * error = nil;
    [imageData writeToFile:storePath options:NSDataWritingAtomic error:&error];

    if (error != nil) {
      NSLog(@"Error: %@", error);
      return;
    }
}
