允許使用的UIImagePickerController直至取消按鈕拍攝照片點擊

Question

我實現拍照功能，我需要讓用戶拍照許多他們喜歡和存儲。我能夠做到這一點，但一次只能有一張照片！用戶必須再次點擊拍照按鈕才能打開相機並拍攝照片。我試圖在保存照片後不關閉UIImagePickerController，但它不起作用！請參閱我的以下代碼。有人能告訴我如何讓用戶繼續拍照，直到他們點擊UIImagePickerController上的取消按鈕。謝謝。

- (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]; 
}
