我正在尝试通过 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。我正在通过以下代码成功访问相册并获取每个图像的资产 URL：
- (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 获得的图像上传到我的服务器。有人可以建议我如何编程以使用这种情况将图像发送到服务器？
谢谢！
