ios – 如何将图像从相机保存到iPhone库中的特定文件夹？

概述嘿,我是iPhone新手,我最近一直试图制作应用程序.基本上,我想要做的是如果用户将从相机捕获任何图像,那么它应该保存在设备库中.我知道如何在照片库中保存照片,这对我有用,但我无法将所有捕获的图像保存到设备库中的特定文件夹(如新专辑)中.我希望用户能够拍摄多张照片,然后将该特定文件夹中的照片复制到图库中. 这是我的代码： - (void)imagePickerController:(UIImage 嘿,我是iPhone新手,我最近一直试图制作应用程序.基本上,我想要做的是如果用户将从相机捕获任何图像,那么它应该保存在设备库中.我知道如何在照片库中保存照片,这对我有用,但我无法将所有捕获的图像保存到设备库中的特定文件夹(如新专辑)中.我希望用户能够拍摄多张照片,然后将该特定文件夹中的照片复制到图库中.

这是我的代码：

- (voID)imagePickerController:(UIImagePickerController *)picker dIDFinishPickingMediawithInfo:(NSDictionary *)info {    Nsstring *mediaType = [info valueForKey:UIImagePickerControllerMediaType];    if([mediaType isEqualToString:(Nsstring*)kUTTypeImage]) {        UIImage *photoTaken = [info objectForKey:@"UIImagePickerControllerOriginalimage"];        self.imageVIEw.image = photoTaken;        //Save Photo to library only if it wasnt already saved i.e. its just been taken        if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {            UIImageWritetoSavedPhotosAlbum(photoTaken,self,@selector(image:dIDFinishSavingWithError:contextInfo:),nil);        }    }    [picker dismissVIEwControllerAnimated:YES completion:NulL];}- (voID)image:(UIImage *)image dIDFinishSavingWithError:(NSError *)error contextInfo:(voID *)contextInfo {    UIAlertVIEw *alert;    if (error) {        alert = [[UIAlertVIEw alloc] initWithTitle:@"Error!"                                           message:[error localizedDescription]                                          delegate:nil                                 cancelbuttonTitle:@"OK"                                 otherbuttonTitles:nil];        [alert show];    }}

我试过这样做下面的代码,但我不知道它在哪里将图像保存到我的iPhone设备中的App资源：

Nsstring *documentsDirectory = [NSSearchPathForDirectorIEsInDomains(NSdocumentDirectory,NSUserDomainMask,YES) objectAtIndex:0];    Nsstring *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"EMS_FolDER"];    Nsstring *folderPath = [documentsDirectory stringByAppendingPathComponent:@"files"];

谢谢您的帮助！

解决方法 您可以使用AssetsLibrary,这将解决您的问题.

- (IBAction)takePhoto{    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;    imagePickerController.editing = YES;    imagePickerController.delegate = (ID)self;    [self presentModalVIEwController:imagePickerController animated:YES];}- (voID)imagePickerController:(UIImagePickerController *)picker dIDFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo{    [self.library saveImage:image toAlbum:@"touch Code Magazine" withCompletionBlock:^(NSError *error) {        if (error!=nil) {            NSLog(@"Big error: %@",[error description]);        }    }];    [picker dismissModalVIEwControllerAnimated:NO];}

这已在这里解释,一个很好的教程..
