Xcode NSRunningApplication Terminate

Question

Hey Everyone,

I have this code:

NSWorkspace *sharedWorkspace = [NSWorkspace sharedWorkspace];
NSString *appPath = [sharedWorkspace fullPathForApplication:appName];
NSString *identifier = [[NSBundle bundleWithPath:appPath] bundleIdentifier];
NSArray *selectedApps =
    [NSRunningApplication runningApplicationsWithBundleIdentifier:identifier];
// quit all
[selectedApps makeObjectsPerformSelector:@selector(terminate)];

which is suppose to close any application running from just the name which is: appName (NSString).

When I debug the app and type in the application name into the NSTextField pointing towards appName, it closes my application instead of the other application I want it to terminate. I replied this question on another post but no one is responding so I thought maybe I can get a response if I start a new post... thanks. (THIS IS NOT A DUPLICATE, its just that people don't respond when I reply bakc...)

Thanks.,

Kevin

Answer 1

Check the Bundle Identifier of your app in the Info.plist of your project and make sure it's unique.

Also, you should determine the value of selectedApps that you're actually passing as an argument. To do this either log it:

NSLog(@"selectedApps: %@", selectedApps);

or (and this is suggested in the comments by Jon Hess), create a breakpoint. You can do this a few ways:

• Place the cursor on the current line and press Cmd-\
• Left click on the line number in the gutter (this link shows an enabled breakpoint)

Once you've set the breakpoint, choose Run->Debug. This will execute your program in the debugger (gdb). Do whatever you normally do to get to the point of failure. However, this time instead of terminating anything, it will stop at the line you specified. at this point you can examine your variables. You can print objective-c instances by issuing a 'po' (print object) command. Thus, you might end up with something like:

(gdb)po appPath
    // gdb will print this
(gdb)po identifier
    // gdb will print this
(gdb)po selectedApps
    // gdb will print this

And you're not entering your app's own name, right?
