After user choose image from the iPhone library with UIImagePickerController
, I want to upload it to my server using ASIHTTPRequest
library.
I know that with ASIHTTPRequest
I can upload a file with the file's URl, but how do I get the image URL?
I know I can get the image UIImagePickerControllerReferenceURL
, that look like this:
"assets-library://asset/asset.JPG?id=F2829B2E-6C6B-4569-932E-7DB03FBF7763&ext=JPG"
is this the URL I need to use?
There are two ways
1:
You can upload the image using the imagePickerController delegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
//Upload your image
}
2:
You can save the picked image url and upload later using this
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSString *imageUrl = [NSString stringWithFormat:@"%@",[info valueForKey:UIImagePickerControllerReferenceURL]];
//Save the imageUrl
}
-(void)UploadTheImage:(NSString *)imageUrl{
NSURL *url = [[NSURL alloc] initWithString:imageUrl];
typedef void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *asset);
typedef void (^ALAssetsLibraryAccessFailureBlock)(NSError *error);
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset){
ALAssetRepresentation *rep = [myasset defaultRepresentation];
CGImageRef iref = [rep fullResolutionImage];
UIImage *myImage = nil;
if (ref) {
myImage = [UIImage imageWithCGImage:iref scale:[rep scale] orientation:(UIImageOrientation)[rep orientation]];
//upload the image
}
};
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror){
};
ALAssetsLibrary* assetslibrary = [[[ALAssetsLibrary alloc] init] autorelease];
[assetslibrary assetForURL:url resultBlock:result block failureBlock:failureblock];
}
Notes: Please make sure the scope of ALAssetsLibrary
object while using ARC.Better to use the ALAssetsLibrary
object as a singleton.
