Hi everyone,
I have an application that I need to restart. An easy way to do this
could be:
[[NSWorkspace sharedWorkspace] launchApplication:executablePath];
[NSApp terminate:self];
The problem is that the above solution results in confusion in the
system dock; sometimes the original application does manage to quit
before the new instance, other times not. If it does NOT manage to
quit before the new one is launched, the dock ends up with two icons
for my application; one that indicates that the application is
launched, another one that's indicates that it's not launched. This is
NOT good.
I've seen other programs in need of a restart (e.g. the Sparkle
framework) using a separate helper application that simply checks
whether the original process has quit properly before re-launching it.
This sure does work, but it isn't a pretty solution.
Another solution could be something like:
system("nohup sh -c 'sleep 1; open -b com.company.identifier'");
exit(0);
This is (in my humble opinion) better, but still, not very elegant.
Wouldn't it be nice if we could have something like [NSApp relaunch],
[NSApp relaunchWithArguments:argArray] etc. to deal with stuff like
this? Or does such calls imply things that I'm overseeing right now?
Maybe there are similar methods already available in the system, that
accomplishes stuff like this?
Any ideas/suggestions on the above are more than welcome.
Thanks in advance.
Mattias
