Question

我在屏幕上创建了两个选项。

使用以下方法从相机捕获图像：UIImagePickerControllerSourceTypeCamera
从UIImagePickerControllerSourceTypeSavedPhotosAlbum。

但是当我拍摄图像时，图像没有存储在设备中？

我的代码是：

-(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{

    NSLog(@"From didDismissWithButtonIndex - Selected Option: %@", [actionSheet buttonTitleAtIndex:buttonIndex]);

    NSString*image=[actionSheet buttonTitleAtIndex:buttonIndex];

    if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Camera"]) {

        if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
        {
            UIAlertView* alert = [[UIAlertView alloc] initWithTitle:nil message:@"Device Camera Is Not Working" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert show];
            return;
        }
        else{

            UIImagePickerController *picker = [[UIImagePickerController alloc] init];
            picker.delegate = self;
            picker.allowsEditing = YES;
            picker.sourceType = UIImagePickerControllerSourceTypeCamera;



            [self presentViewController:picker animated:YES completion:NULL];

        }
    }

    else if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Gallery"])
    {
        UIImagePickerController *pickerView = [[UIImagePickerController alloc] init];
        pickerView.allowsEditing = YES;
        pickerView.delegate = self;
        [pickerView setSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];

        //[pickerView setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
        [self presentViewController:pickerView animated:YES completion:nil];

    }
}

//=====================================Image picker ===============================================


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{

    UIImage* orginalImage = [info objectForKey:UIImagePickerControllerOriginalImage];

    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:isRowIndex inSection:isSectionIndex] ;

    UITableViewCell *cell = [jobstable cellForRowAtIndexPath:indexPath];

    UIImageView *tableIMAGE=(UIImageView *)[cell.contentView viewWithTag:19];

    tableIMAGE.image=orginalImage;

    imageStris = [UIImageJPEGRepresentation(tableIMAGE.image,1)base64Encoding];

    answersARRAY[indexPath.row] = [NSString stringWithFormat:@"-1,%@,%@",answersARRAY[indexPath.row],imageStris];

    [self visubull];

    [self dismissViewControllerAnimated:YES completion:nil];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

    [picker dismissViewControllerAnimated:YES completion:NULL];

}

Answer 1

这是因为你没有对图像做任何事情。您将它作为b64字符串分配给一个数组，就是这样。您必须手动将其保存到相机胶卷：

UIImageWriteToSavedPhotosAlbum(tableIMAGE.image, nil, nil, nil);

Answer 2

只需将此行放入 UIImageWriteToSavedPhotosAlbum(orginalImage,nil, nil, nil); 即可存储图片

捕捉图像时，必须手动存储。

希望这会对你有所帮助

Answer 3

你必须像这样

在didFinishPickingMediaWithInfo中保存图像相机胶卷

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage   *image =  [info objectForKey:UIImagePickerControllerOriginalImage];
if(picker.sourceType==UIImagePickerControllerSourceTypeCamera)
                            {

                                [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
                                    [PHAssetChangeRequest creationRequestForAssetFromImage:image];
                                } completionHandler:nil];
                            }
}

捕获的图像未保存在设备中
