dismissModalViewControllerAnimated：不關閉模式視圖

Question

捕獲圖像後，發生回調但發生錯誤，因爲它沒有關閉相機視圖。我的代碼非常簡單，我唯一的疑問是我使用了一個標籤欄控制器，並在其中一個選項卡中推送了imagePicker，只是一個想法。

- (IBAction)imageButtonPressed:(id)sender { 
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; 
    imagePicker.delegate = self; 
    imagePicker.allowsEditing = YES; 
    [self presentModalViewController:imagePicker animated:YES]; 
} 



- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    [self dismissModalViewControllerAnimated:YES]; 
    self.portaitImage.image = [info objectForKey:UIImagePickerControllerOriginalImage]; 
}

您需要解僱的UIImagePickerController，不self：

[picker dismissModalViewControllerAnimated:YES];
