GetProcessPID
was marked deprecated in OSX 10.9 along with the note:
Use the processIdentifier property of the appropriate NSRunningApplication object.
The problem is the constructing class methods for NSRunningApplication
do not have a way to get a NSRunningApplication
by a ProcessSerialNum
, only by PID or bundle name.
Bundle name is too ambiguous (there could be multiple instances) and I don't have the PID (it's what I want).
In OSX 10.9, is there a way to get the PID when you have a PSN?
Observe the NSWorkspaceDidLaunchApplicationNotification
notification.
In the callback, get the process serial number as follows:
NSDictionary* dictionary = [notification userInfo];
NSNumber* psnLow = [dictionary valueForKey: @"NSApplicationProcessSerialNumberLow"];
NSNumber* psnHigh = [dictionary valueForKey: @"NSApplicationProcessSerialNumberHigh"];
ProcessSerialNumber psn;
psn.highLongOfPSN = [psnHigh intValue];
psn.lowLongOfPSN = [psnLow intValue];
NSRunningApplication *newApplication = [dictionary valueForKey:NSWorkspaceApplicationKey];
If you use the method runningApplicationsWithBundleIdentifier
of the class NSRunningApplication
, you will get an NSArray of NSRunningApplication.
You may then read these objects' properties (bundle URL, localized name…) to identify the object you are interested in, at last get its PID.
