Let me specific. I have three XIBs. From the first XIB i used pushViewController and got into the second. From the button click in second XIB i got into the third. The thing is, On the click of Cancel button in third ViewController I have to go the first XIB. How is this possible? I am stuck there. Help me please. I used the navigationController to push the viewControllers. I have already used the popToRootViewController: but it popped only to the second XIB.
use this
[self.navigationController popToRootViewController:YES];

I've got the following problem. I want to test my application with Espresso. Therefore I want to click a button which is part of the "Buttons" fragment, this fragment is located in a frame-layout in the MainActivity.
Ofcourse I can check if the frame-layout is displayed but I can not reach the layout of the fragment which is located into the frame-layout.
So my question is, how can I reach the layout of the fragment into the frame-layout, so I can click on a button into the fragment.
The result at the moment is a NoViewMatchException:
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id:...
Thanks in advance!
Edit: The exception shows the view hierarchy
These are the methods I'm calling:
onView(ViewMatchers.withId(R.id.buttons)).check(matches(isDisplayed()));
This is the frame-layout in the MainActivity for the buttons fragment:
onView(withText("LOCATIONS")).perform(click());
The locations buttons is in the Buttons fragment
withId on the button id in stead of withText doesn't make sense.
The question is not very clear. It does not matter which layout you are using. Espresso can locate the element on the view hierarchy. If your case, you're getting NoViewMatchException. That means the view (R.id.buttons) is not there when you're checking.
For debugging, you can add some wait (SystemClock.sleep(2000)) and check if it works.
If that works, you need to write the idling resource to wait for the buttons fragment to appear.
I have a dialog based application. I have one static text control and a button on this, both of which I have made invisible in the beginning. I want to show both the controls on reaching a certain condition. When I click this button, again I want to make both the controls invisible.
However, I am able to show and hide the control and also captured the button click event like this:
ON_BN_CLICKED(IDC_MY_BUTTON, &MyDlg::OnBnClickedMyButton)
and defined OnBnClickedMyButton().
But when I press the button, it is not pressed and the event is also not generated.
Any suggestions?
First check if the IDC_MY_BUTTON exists and is valid.
Remember to add DECLARE_MESSAGE_MAP() at the header file.
Also check at the BEGIN_MESSAGE_MAP(MyClass,MyParentClass) if the class
and the parent class you write are right.
I hope this helps.
I think the IDC_MY_BUTTON maybe is invalid or other control has the same ID.
Well, finally I have come to know that though the button was visible but on clicking it was not taking control, hence I used BringWindowToTop() to draw it on top. Now it is being clicked and OnBnClickedMyButton() is also being called.
But now the issue is that after calling BringWindowToTop() the button is not shown. It is shown only when I take the mouse pointer on it. Not able to understand what is the issue.
I have a problem that has been solved on iOS6, but still appears if I use the iOS 5.1 simulator.
I have a default page based application. I added a "Main menu" view controller, that has three buttons that activate the root view controller containing the pages via a push segue, all defined in the storyboard.
I then added a navigation controller and made it the initial view controller.
If I pas the menu via a button and flip a few pages I can click the back button and it goes back to the menu. Good.
But I don't want the nav bar, so I hide it, and on the root view controller that contains the page view controllers I add a button which performs this action:
[self.navigationController popToRootViewControllerAnimated:YES];
This button works perfect on iOS6, I can flip a few pages, press the button and I'm back in the menu.
With the iOS 5.1 simulator however (and on my 5.1 iPad), a page flip occurs! It's a page filp until I'm on the last page and then I go back to the menu.
I searched for over two hours now but could not find a solution, I hope someone can help me with this?
Note: setting animated to NO does not solve the problem.
I did find the answer to my question, this is my first iOS project which explains why I did not find it any sooner myself.
In the default page based application there are two lines in the viewDidLoad method:
// Add the page view controller's gesture recognizers to the book view controller's view so that the gestures are started more easily
self.view.gestureRecognizers = self.pageViewController.gestureRecognizers;
First, it's not really adding but assigning that happens here, second, when I put the second line in comment, everything works as expected.
So I'm glad it solves my problem, however it raises some questions:
The gestures are started as easy as they were, so why was this line needed in the first place, what does it supposedly fix?
Why does it work in iOS6? It should have had the same problem, no?
Is it correct that it is an assignment and not an addition?
Any answers to these three are still appreciated.

I have a Navigation Controller and a tableView with several Entries. If i select an Entry a new DetailViewController gets pushed. in the DetailViewController you can swipe right to push the DetailViewController of the next Entry of the tableView. Its working pretty well, but if people swipe about 10 times, they need to press the back button 10 times to get back to the tableView. So I'm looking for a nice way for people pressing back and coming to the tableView.
I thought about recreating the backbutton and use the popToRootViewControllerAnimated:
but is there another way i can solve my problem?
maybe something like deleting all views on the navigation stack and keep only the last one.
Instead of pushing a new DetailViewController you could just update the details with the details from the next/previous Entry from the tableview.
You would lose the swipe/push animation, but this could be worked around.
Another possibility is to use:
[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];
You'll need to work out what index the tableViewController is. If it's the root view controller then the index should be 0.
I'm using MonoTouch and my application setup looks something like this,
NavController
-TabBarController
-NavController
-View1
This works then I click on a tab and am directed to View1. The problem is that this was performed by the tabBarController and not the navigationController. So I get no Back button. Is there a way to capture a TabItemClicked event and manually use the NavigationController to push the View1 onto the stack? So I can get a back button.
I'm hiding the TabBar once I get to View1, so at the moment, there is no way back from View1.
Hope it may help you
