After the video is streamed, the app goes to the background, stays for a while, and then comes back to the foreground. This might cause the app to crash. How do I deal with this problem?

1. Check whether the error message Terminated due to signal 13 is returned.
2. Add the following code block to main.m:

int main(int argc, char * argv[]) {
    @autoreleasepool {

            struct sigaction sa;
            sa.sa_handler = SIG_IGN;
            sigemptyset(&sa.sa_mask);
            sa.sa_flags = 0;

            if (sigaction(SIGPIPE, &sa, NULL) < 0) {
                perror("cannot ignore SIGPIPE");
                return-1;
            }

            returnUIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}
