iOS中存储图片到相册中的两种方式

方式一：

UIImageWriteToSavedPhotosAlbum(self.imageV.image,self, @selector(image:didFinishSavingWithError:contextInfo:),nil);

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{

    

    if (error) {

        [SVProgressHUDshowErrorWithStatus:@"保存失败"];

    }else{

        

        [SVProgressHUDshowSuccessWithStatus:@"保存成功"];

    }

}

方式二：

NSError * error = nil;

    __blockNSString * assetID = nil;

    [[PHPhotoLibrarysharedPhotoLibrary] performChangesAndWait:^{

       assetID =  [PHAssetChangeRequestcreationRequestForAssetFromImage:self.imageV.image].placeholderForCreatedAsset.localIdentifier;

    } error:&error];
