Dear Peter, thank you for your quick and very specific help. I must
have been blind or happy to have made Growl work so easily (the
registration ticket method) and didn't consider digging to the .h
files (out of respect to the developers' work perhaps, or just not
being "nosy" in nature).
As I said, I am an in-experienced programmer... So for anyone checking
this in the future, here is the new/proper (and much simpler!)
approach to the problem:
+(void)initialize
{
// Growl is NOT installed
if ([GrowlApplicationBridge isGrowlInstalled] == NO)
{
NSAlert *warnCalendar = [NSAlert alertWithMessageText:
[[NSRunningApplication currentApplication] localizedName]
defaultButton: @"Exit" alternateButton: nil otherButton: nil:
informativeTextWithFormat: @""];
[warnCalendar setAlertStyle:NSCriticalAlertStyle];
[warnCalendar setInformativeText: @"Growl framework was not
found
on
your system! Please install Growl frist from www.growl.info!"];
// Display warning then terminate application
[warnCalendar runModal];
[NSApp terminate:self];
}
// Growl is apparently installed
else if ([GrowlApplicationBridge isGrowlInstalled] == YES)
{
NSLog(@"System reports that Growl is installed.");
}
}
At least, in my old code, I learned how to check for files :-)
Peter, one last question, please. What should come first, in Xcode app
execution sequence? The check whether Growl was loaded by the
application, or calling Growl's own function to check for system
installation?
Is (void)initialize a good place to do the check, or do you suggest
(void)awakeFromNib instead?
I cannot see it clearly... if Growl was not loaded by the application
(as per [growlBundle load] code sample in the developers
documentation) can it still execute [GrowlApplicationBridge
isGrowlInstalled] ?
Many thanks.
