将ALAsset URL映像上载到服务器 [英] Upload ALAsset URL images to the server

问题描述

我正试图通过ALAssetsLibrary访问iPhone的相册照片图像，并将图像上传（发送）到我的服务器。我通过以下代码成功访问相册并获取每张图片的资产网址：

I am trying to access iPhone's photo album photo images through ALAssetsLibrary and upload(send) the images to my server. I am being successful accessing the photo album and get the asset URL of each images, via the following code:

    - (void)viewDidLoad
{
    [super viewDidLoad];


    void (^assetEnumerator)(struct ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop) {
        if(result != NULL) {
            NSLog(@"See Asset: %@", result);
            [assets addObject:result];
            // Here storing the asset's image URL's in NSMutable array urlStoreArr
            NSURL *url = [[result defaultRepresentation] url];
            [urlStoreArr addObject:url]; 
        }
    };

    void (^assetGroupEnumerator)(struct ALAssetsGroup *, BOOL *) =  ^(ALAssetsGroup *group, BOOL *stop) 
    {

        if(group != nil) {
            [group enumerateAssetsUsingBlock:assetEnumerator];
        }
        [self.activity stopAnimating];
        [self.activity setHidden:YES];
    };
    assets = [[NSMutableArray alloc] init];
    library = [[ALAssetsLibrary alloc] init];
    [library enumerateGroupsWithTypes:ALAssetsGroupAlbum
                           usingBlock:assetGroupEnumerator
                         failureBlock: ^(NSError *error) {
                             NSLog(@"Failure");
                         }];

    urlStoreArr = [[NSMutableArray alloc] init];
}

    -(void) UploadImagesToServer
{

for (int i=0; i<[urlStoreArr count]; i++)

{

       // To get the each image URL here...

        NSString *str = [urlStoreArr objectAtIndex:i];
        NSLog(@"str: %@",str);

        // Need to upload the images to my server..

    }


}

我想将从设备资产的URL上获取的图像上传到我的服务器。有人可以建议我如何使用这种情况编程将图像发送到服务器？

I want to upload the images which i got from the device asset's URL to my server. Could someone please advise how can i program it for sending the images to the server using this case?

谢谢！
