Question

我的应用程序是基于标签栏的应用程序。我必须提供一个选项，用户可以在个人资料编辑屏幕中更改他的个人资料图片。为此，当用户点击编辑栏按钮时，我从个人资料界面推送个人资料编辑屏幕

UITabBarViewController --> UINavigationController -->ProfileView (UIViewController) --Push--> ProfileEditView(static UITableViewController)

我使用以下代码

呈现UIImagePickerController

 UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
 imagePicker.delegate = self;
 imagePicker.allowsEditing = YES;
 // imagePicker.modalPresentationStyle = UIModalPresentationOverCurrentContext; (when i use this TabBar hiding cancel and chose buttons)
 imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
 [self presentViewController:imagePicker animated:YES completion:nil];

和委托方法

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    profileImage = info[UIImagePickerControllerEditedImage];
    [_choseProfilePicButton setBackgroundImage:profileImage forState:UIControlStateNormal]; 

    if ([picker isKindOfClass:[UIImagePickerController class]])
    {
        [picker dismissViewControllerAnimated:YES completion:nil];
    }
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [picker dismissViewControllerAnimated:YES completion:nil];
}

当我尝试选择图像并点击选择图像当前视图返回到配置文件屏幕（配置文件屏幕 - 推送 - ＆gt;配置文件编辑视图 - ＆gt;呈现imagePicker控制器 - ＆gt;选择图像 - ＆gt ;回到配置文件屏幕）。选择父视图后，而不是图像选择器控制器。需要关闭图像选择器控制器并选择图像后保持在同一屏幕。请帮我这个如何摆脱这....

谢谢，

我处于一个非常相似的情况，通过将图像选择器的modalPresentationStyle设置为＆＃34; OverCurrentContext＆＃34;来解决问题：

func photoButtonPressed(sender: AnyObject) {
    let picker = UIImagePickerController()
    picker.delegate = self
    picker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    picker.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
    presentViewController(picker, animated: true, completion: nil)
}

1.创建一个baseViewController。

2.设置框架并将baseController添加到根视图控制器视图。

3.从baseViewController中显示你的imagePickerController。

4.成功获取图像后，从superview中删除baseViewController的视图。

self.baseViewController = [[UIViewController alloc] init];

[APP_DELEGATE.rootViewController.view addSubview:self.baseViewController.view];

[self.baseViewController.view autoPinEdgesToSuperviewEdgesWithInsets:UIEdgeInsetsFromString(@"0,0,0,0")];
//You can also set frame ,I have used purelayout so the above step

[self.baseViewController presentViewController: self.myPicker.imagePickerController animated:YES completion:^ {}];


//Last step after picking up image
[self.baseViewController.view removeFromSuperview];

UIImagePickerController在图像选择中消除父视图
