Hi all,
I'm trying to create an simple application using Apple Events to
see if a specified application is running (iTunes in my case). A
thread from main.m will use the mainProcess method so the script
will run every second. The problem I'm having is that the
NSAppleEventDescriptor i'm using (result) isn't deallocated and the
every 100 secs it grows with 1Mb of memory. Can someone help me
please ... I've tried release, dealloc, autorelease and isn't
working. Please if you know give me some ideas how to solve this
problem in cocoa. Thanx guys.
This is the code I'm using:
-(void)isAppRunning
{
NSString* appleEventString = [NSString stringWithFormat:@"set
itunes_active to false\n with timeout of 1 second\n tell
application \"Finder\"\n if (get name of every process) contains
\"iTunes\" then set itunes_active to true\n end tell\n end timeout
\n return itunes_active"];
NSAppleScript *script = [[NSAppleScript alloc]
initWithSource:appleEventString];
NSDictionary *errorInfo;
NSAppleEventDescriptor* result;
result = [script executeAndReturnError:errorInfo];
NSLog(@"%@", [result stringValue]);
[result dealloc];
[script dealloc];
}
-(void)mainProcess:(id)anObject
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
while (1)
{
[self isAppRunning];
}
[pool release];
}
You shouldn't be calling dealloc yourself. That is up to Cocoa to
deal with. You should review the memory management guide several
times (from my experience it takes awhile to start to understand.
