iOS帮助:如何使用相机拍照并将其保存在iPhone上？

Question

我是iPhone发展新手.我需要创建一个应用程序,用户可以拍照,然后将其保存在iPhone上,我还必须使用SQLite数据库存储图像,然后显示它.

任何人都可以帮我提供示例代码和程序说明吗？

编辑:我做了一个使用UIImageView拍照的按钮,但我不确定它是否有效,因为我没有iPhone:

if ([UIImagePickerController isSourceTypeAvailable:
     UIImagePickerControllerSourceTypeCamera])
{
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    imagePicker.sourceType = 
    UIImagePickerControllerSourceTypeCamera;
    imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
    imagePicker.allowsEditing = NO;
    [self presentModalViewController:imagePicker animated:YES];
    imagePicker = nil;
    newMedia = YES;
}

上面的代码使用前置摄像头

您可以使用UIImagePickerController类来拍照...您可以使用以下方法捕获图像并存储它.

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

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    //put code for store image
 }
