objective c - iOS Multitask App Switcher Custom Image -

-

im developing ios app , behave paypal when user double taps home button.

for dont know paypal app displays custom image when app displayed on multitask switcher doesnt when notification arrives or when user pulls notifications bar.

my issue comes when implementing this, im using event applicationwillresignactive display custom image (as applicationenteredbackground not called this). method called on events on dont want app display image (such notifications, calls, pulling top bar, etc).

is there way of setting image when home button double tapped? thank you!

from see, paypal doesn't cover viewport custom image – when double tap home button, remains rendered until else – on applicationdidenterbackground:. after switching home screen or application, paypal preview becomes covered.

on other hand, mobile banking application when applicationwillresignactive: triggered.

these afaik 2 approaches can achieve.
