how can i write a NSData file as Video in to Photolibrary/SavedPhotosAlbum?
i have a Video file as NSData.how can i write the NSData file as Video in to Photolibrary/SavedPhotosAlbum?
i done it with UIimage through the following code. i had a UiImage as myNsData(NSData)
UIImage *viewImage = [UIImage imageWithData:myNsData];
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
// Request to save the image to camera roll
[library writeImageToSavedPhotosAlbum:[viewImage CGImage] orientation:(ALAssetOrientation)[viewImage imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){
}
how can i do it the same functionality for Video.
i searched in NSData calss .
i found only two ways. they are
(void)writeVideoAtPathToSavedPhotosAlbum:(NSURL *)videoPathURL completionBlock:(ALAssetsLibraryWriteVideoCompletionBlock)completionBlock;
- (BOOL)videoAtPathIsCompatibleWithSavedPhotosAlbum:(NSURL *)videoPathURL;
two of them are using URL.actu开发者_C百科ally i didn't want to write the NSData file any where except in Photolibrary/SavedPhotosAlbum.
i need to write the NSData file directly in to the Photolibrary/SavedPhotosAlbum like i saved an image.How can do that?can any one Help me?
You need to create an AVAssetWriter with a video AVAssetWriterInput and add your data into the input.
When you create the AVAssetWriter, you need to specify an URL for the asset.
After you can use the ALAssetsLibrary (writeVideoAtPathToSavedPhotosAlbum:completionBlock:) to write the asset to the photo library, with the url of the asset created above.
