允许使用的UIImagePickerController直至取消按钮拍摄照片点击

Question

我实现拍照功能，我需要让用户拍照许多他们喜欢和存储。我能够做到这一点，但一次只能有一张照片！用户必须再次点击拍照按钮才能打开相机并拍摄照片。我试图在保存照片后不关闭UIImagePickerController，但它不起作用！请参阅我的以下代码。有人能告诉我如何让用户继续拍照，直到他们点击UIImagePickerController上的取消按钮。谢谢。

- (IBAction)takePhoto:(id)sender 
{ 

    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) 
    { 
     UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
     imagePicker.delegate = self; 
     imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
     imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]; 
     [self presentModalViewController:imagePicker animated:YES]; 
    } 
} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) 
    { 
     UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; 
     NSData *imageData = UIImageJPEGRepresentation(image, 1); 
     [imageData writeToFile:[delegate filePath:imageName] atomically:YES]; 
    } 

    [picker dismissModalViewControllerAnimated:YES]; --> If I remove this then Camera stays open but Photo click button gets disabled! If I don't remove this it dismiss the camera. 

} 

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 
{ 
    [picker dismissModalViewControllerAnimated:YES]; 
}
