Is it possible to show the 'first-instance' window on 'second-instance' event?
The case I am trying to achieve is to show the first instance's window whenever the user tries to open a second instance of the electron app.

I am using NYAlertViewController to display dialogs in my iOS-App. It can happen that I just opened a dialog when a background process tries to trigger another dialog. If this happens, the second dialog is not shown. I would like to close all other dialogs before opening a new one. How could I do this?
The Dialogs are shown with presentViewControllerAnimatedCompletion.
Maybe I can dismiss all ViewControllers that are instances of NYAlertViewController?
Any thoughts on that? Thanks!
I am creating a app where i can set the reminder based on Location and date.Apple has already given the UI if you are using Reminder which has both option.Can any one help me out that how can i open that Create event screen.
Unless done explicitly, is the only time a UIManagedDocument closed when the app is "quit"? By quit I mean when the user double taps the home button and holds onto the apps and closes them out.
I ask because right now I have my app in a tabBarController and I'm using the tabBarController to handle all the UIManagedDocuments since every other view controller has access to it via self.tabBarController. Right now my tabBarController will check if the UImanagedDocuments exist, are in a closed state, or are in an open state and deals with it accordingly to yield an open document ready to use. I'm doing this in viewWillAppear. I noticed that viewWillAppear for a tabBarController is only called once in the lifetime of the app before it is "quit". So I'm wondering if I need my other view controllers to check if the UIManagedDocuments they use are open before they use them or can I assume they will remain open until the app is "quit" if I don't explicitly close them anywhere in my code?
I have not seen this behavior where the UIManagedDocument closes when the application loses focus. I do believe you have to close the document explicitly if you want it closed. But to know for sure you can sign up for the UIDocumentStateChangedNotification and see exactly when it goes into a closed state.
I am developing an application where I want to show a popup screen at a regular frequency selected by the user, even if my application is closed.
I am able to show a popup screen in regular intervals when my application is in the foreground. But I am not able to show a popup screen when my application is in the background.
I tried UIApplication.requestBackground() method, which invokes Application.deactivate() method, and on that method I am calling a timer. But it is not giving me any output, not even exceptions.
You want to use UiApplication.pushGlobalScreen() to get a popup to appear when your app is in the background.
I have a simple iOS app that I am developing that needs to be "restarted" or "reset" after a user performs a certain touch action and a "reset" button appears. The workflow of the app goes something like this:
User holds a certain area of the screen
User lets go of the screen and quickly touches another area
The time it took for them to let go and touch the next area is displayed in a UILabel.
A reset button appears in which the user presses to try again.
Steps 1-3 work perfectly, but currently the only way I have to "reset" the app is to exit with the home button, open the multi-tasking menu and manually close it and re-open it.
I know this has to be able to be done as I 've seen it in many apps. I just can't find much help with the developer docs on it.
Thanks!
You can kill the app with a call to abort(). There's no way to start it after you killed it, though.
Perhaps you can schedule a local notification before killing the app that prompts the user to open it again.
You should probably just create a method that resets all of your variables and then calls the methods that begin steps 1-3. To have the button appear, make a UIButton IBOutlet to attach to the reset button, and then hide it in viewWillAppear like this:
[myButton setHidden:true];
To then show the button later, use the same button but set the value to false instead of true.
You could try removing your view controller from the application window and releasing it then instantiating a new instance of that view controller and adding the new instance to the window as the root view controller.
Since I'm assuming your view controller is where most of your "setup" code for your app is occurring this should effectively reset the app without having to write a lot of extra code. In addition, having the ability to instantiate a new instance of your view controller class is kinda the point of having it to begin with.
You can sleep your application for specified time interval.
+ (void)sleepForTimeInterval:(NSTimeInterval)ti
or
+ (void)sleepUntilDate:(NSDate *)aDate
Methods is works for you
