カメラで撮った画像をカメラロールに簡単に保存できます。ただし、これがカメラロールから選択された場合、複製が作成されるため、画像を保存したくありません。
次のことを選択してカメラロールに保存するにはどうすればよいですか?
編集1:rmaddyが言ったように、私は次のことができます。picker.sourceTypeがUIImagePickerControllerSourceTypeCameraと等しい場合にのみ、カメラロールに保存します。
ただし、そうすると、選択した画像の情報、主にファイル名を取得できなくなります。
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
[self.myImageView setImage: image];
[self.myImageView setContentMode:UIViewContentModeScaleAspectFit];
ALAssetsLibrary *al=[[ALAssetsLibrary alloc] init];
// ------> Saving to Camera Roll <------------
[al writeImageToSavedPhotosAlbum:[image CGImage] metadata:nil completionBlock:^(NSURL *assetURL,NSError *error) {
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myAsset) {
ALAssetRepresentation *rep = [myAsset defaultRepresentation];
NSString *fileName = [rep filename];
ImageInfo *imgInfo = [[ImageInfo alloc] initWithEventId:0 name:fileName image:UIImageJPEGRepresentation(image, 1.0)];
imgInfo.isDirty = YES;
[self.imagesArray addObject:imgInfo];
[self dismissViewControllerAnimated:YES completion:nil];
NSLog(@"Image from Camera %@ added to imageArray",fileName);
};
ALAssetsLibrary *assetsLibrary = [[ALAssetsLibrary alloc]init];
[assetsLibrary assetForURL:assetURL
resultBlock:resultblock
failureBlock:nil];
}];
}
else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie])
{
// Code here to support video if enabled
}

このMODで解決:(コードの重複が少しあることはわかっていますが、後で改善しようとします)
if (newMedia){
ALAssetsLibrary *al=[[ALAssetsLibrary alloc] init];
[al writeImageToSavedPhotosAlbum:[image CGImage] metadata:nil completionBlock:^(NSURL *assetURL,NSError *error)
{
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myAsset)
{
ALAssetRepresentation *rep = [myAsset defaultRepresentation];
//NSString *fileName = [rep filename];
NSString *imgUrl = [[rep url] absoluteString];
ImageInfo *imgInfo = [[ImageInfo alloc] initWithEventId:0 imgUrl:imgUrl image:UIImageJPEGRepresentation(image, 1.0)];
imgInfo.isDirty = YES;
[self.imagesArray addObject:imgInfo];
[self dismissViewControllerAnimated:YES completion:nil];
NSLog(@"Image from Camera %@ added to imageArray",imgUrl);
};
ALAssetsLibrary *assetsLibrary = [[ALAssetsLibrary alloc]init];
[assetsLibrary assetForURL:assetURL
resultBlock:resultblock
failureBlock:nil];
}];
} else {
NSString* imgUrl = UIImagePickerControllerReferenceURL;
ImageInfo *imgInfo = [[ImageInfo alloc] initWithEventId:0 imgUrl:imgUrl image:UIImageJPEGRepresentation(image, 1.0)];
imgInfo.isDirty = YES;
[self.imagesArray addObject:imgInfo];
NSLog(@"Image from Camera Roll %@ added to imageArray",imgUrl);
[self dismissViewControllerAnimated:YES completion:nil];
}
