When I kill an app it crashes, what to do?

Question

Whenever I load my application to my iPhone it works just fine, but when I kill it(double tap the home button and kill it) and launch it again it freezes and crashes. I am quite new to programming so what should I do? Do I have to do something in the appdelegate file or what?

Answer 1

if you manually killed your APP on your iphone while you are debugging using xcode ,

your APP will receive a signal(maybe SIGKILL , not sure) ,

as you are in debug mode , xcode can show you that, it's normal & don't have to do anything

if your APP is running in normal mode, then you killed it , your APP will just exit & relaunch again next you run it
