I am currently making a game for the iphone using cocos2d.

The game runs perfectly until I try to restart the program. If I exit, end the app (double click on the home button and then delete the game icon from the currently running apps bar), and then relaunch, it gives an error. If I exit and relaunch without ending the program, it resumes where it left off. I have yet to test this on an actual iphone, only the simulator. It does not crash the first time the app starts. can anyone help?

this is the line that the program crashed on : (it’s from main.m)

int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");

with the following error: Thread 1: program received signal: “SIGKILL”

here’s the output:

    I’ve found in Xcode 4, for any app, if you are running with breakpoints allowed (debug mode), and then go to home screen, and close the app (double click home button etc), and then try to start it from home screen (all without stopping the current xcode debug session), it freaks out (even after you hit continue in the debugger from the SIGKILL for you closing your app). I wouldn’t worry about it for now if it resumes fine and starts the first time fine.

    This also appears to happen if you are debugging on a device (plugged in using Xcode), but if you unplug the device and try to replicate the issue as a stand alone, it works fine.

    I haven’t submitted it to apple, but please feel free to. 🙂
