I want to know why this crash happens.

I set a GCD timer, when my app is in the background, and when time comes, it will crash like this:

Exception Type:  EXC_CRASH (SIGKILL)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Exception Note:  EXC_CORPSE_NOTIFY
Termination Reason: Namespace SPRINGBOARD, Code 0x8badf00d
Triggered by Thread:  0

Filtered syslog:

And what is your question? – Andreas Jan 16 '17 at 13:08
@Andreas I want to know why it happen. – CoderZyc Feb 18 '17 at 10:13
Don't have access to Xcode atm, but interesting behavior. Maybe this sheds some light on it: http://stackoverflow.com/questions/773442/what-does-8badf00d-mean – Andreas Feb 20 '17 at 00:31
Perhaps the timer keeps your app alive until the watchdog kills it? – Andreas Feb 20 '17 at 00:33
@Andreas Is there anyway to keep app alive even it's in the background for a very long time? – CoderZyc Mar 13 '17 at 12:00
There are official use cases that allow it. No other way. – Andreas Mar 13 '17 at 12:53
did you solve the issue @CoderZyc. – vijju Jan 18 '18 at 04:03
