ios - dismissModalViewControllerAnimated : does not dismiss the modal view

Question

捕获图像后，回调发生，但出现错误，因为它没有关闭相机 View 。我的代码非常简单，我唯一的疑问是我使用的是选项卡栏 Controller 并将 imagePicker 推送到其中一个选项卡中，这只是一个想法。

- (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];
}

Answer 1

你需要关闭 UIImagePickerController，而不是 self:

[picker dismissModalViewControllerAnimated:YES];
