Question

I want to obtain the referenceURL to the image that I saved into camera roll using UIImageWriteToSavedPhotosAlbum(). iOS 4.1 or above can do it easily by using AssetLibrary.

ALAssetsLibraryWriteImageCompletionBlock completionBlock = ^(NSURL* url, NSError* error) {
    if (error == nil) {
        savedURL = url;
    }
};    
UIImage * originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
NSMutableDictionary * metadata = (NSMutableDictionary *)[info objectForKey:UIImagePickerControllerMediaMetadata];  
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeImageToSavedPhotosAlbum:originalImage.CGImage
                             metadata:metadata
                      completionBlock:completionBlock];

但是,在早期的Si-Si,为摄像图书馆保存图像的唯一途径是UIImageWrite ToSavedPhotosAlbum(Saved)。我认为,一种方式是利用ALAssets来审视挽救的形象。小组等。这对我来说不是聪明的,它只会帮助4国集团。

Thank you in advance,

用于书写而是:

[library writeImageToSavedPhotosAlbum:[originalImage CGImage] orientation:(ALAssetOrientation)[originalImage imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){  
    if (error) {  
        NSLog(@"error");  // oops, error !
    } else {  
        NSLog(@"url %@", assetURL);  // assetURL is the url you looking for 
    }  
}];
