we are developing hybrid application on Worklight.
After the user launches the application on iOS, he will see the login screen, providing his credentials, he is inside our application.
Now, if the user clicked the home button for iOS before "logging out" from the app, the iOS will take a snapshot and store it inside the device cache.
By using IExplorer, I can see this screen cached, which in our situation a high critical issue.
How can I a override this screen with a white screen, in case the user clicked the home button of the iOS device it will be populated immediately, and the device will not snapshot the user main screen.?
Is there any thumbnail I can add to my nativeResource folder for iOS to solve this issue?
thank you.
I encourage you to look at the Worklight Knowledge Center. In most cases, you will find your answer.
To control the snapshot taken by the OS when moving to the background, you need to use the following API methods, depending on your needs:
WL.App.BackgroundHandler.setOnAppEnteringBackground and WL.App.BackgroundHandler.setOnAppEnteringForeground

I am developing a security application. I need to disable the multitasking snapshot from being taken by iOS. I have made a fix for this by adding a black screen over my application window, when application resigns active mode. This logic seems to work fine when I press home button. But when I lock the screen, the logic is not effective, since the snapshot is already taken before control comes to applicationWillResignActive method. I have verified this by downloading the container folder from devices tab. Is there any way to fix this?
Thanks in advance!
I have home screen quick actions for my iOS 9 app, but I don't need it to open the app. It actually schedule reminders and that's it. Is there a way to make the home screen quick action not to open the app?
Quick actions are designed to be used to quickly navigate to a section of your app, eg on the camera app there is selfie mode, box mode, panorama mode, timelapse mode etc. These are all sections of the app. To the best of my knowledge you cant have a quick action that just runs code without opening the app. Otherwise how will the user know that the code has worked and it has been executed?
This functionality would be cool but i believe it is impossible as of current. The closest you can get is make it so it opens the app to a ViewController that just says "Reminder Scheduled".
I am developing an iPad application & I want to keep use only my application in iPad. User is not able to make any changes with Home button too.
I have tried same thing with "Guided Access". But, it will stop push notification also.
I have tried it with iPhone configuration Utility. But, I am not able to find any
restriction for Home button.
So, anyone have any idea how can I implement it?
You can't disable the Home button from the sandbox.You have to use the physical accessories to stop the Home button action, after opening your application.
I have developed an iOS enterprise app for iPad. When it is launched it connects to a webservice, gets some data, and stores it in Core Data. Then the next screens use this data and do what is needed, like fill UITextFields, drop downs, show the user a UIAlertView, etc. Basically i use the data, manipulate it, and save it.
Consider this: I install the app now in morning, I use it immediately, and then I click the home button on iPad and leave it there for couple of hours. I then launch the app, and it shows a black screen before crashing and going back to iPad main menu.
Why is it crashing like that? Any ideas?
If you need more information please let me know.
You need to check your logs for errors.
Plug your device to your computer and open Xcode/Organizer/Devices/Device Logs
I recently upgraded my old iPhone app and the new state restore iOS 3/4 feature has introduced a problem. I don't know the name of this restore state feature - what is it called?
Here is my problem scenario:
I navigate into a detail screen on my app. I click a button to navigate to an address and it launches google maps as expected. Then I launch my app again. It briefly shows the last screen I was on, but immediately launches the google map again.
What I want is to simply restore the detail screen that I was last on.
Any hints?
thanks
It is called multitasking, and it is built in automatically when you build under iOS 4.0+. Without you posting any code, it is tough so say, but why don't you put a breakpoint at the line that redirects to Google Maps and see what is calling it. Then you can backtrack to see why it is being called on the reopening of the app.
