site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com Hi, In my plugin code, I’m leveraging the code in https://lists.apple.com/archives/Installer-dev/2008/Nov/msg00017.html <https://lists.apple.com/archives/Installer-dev/2008/Nov/msg00017.html> to get the path to my installer pkg. This has been working for me for the past few years on all the Mac OSes that have been released, but it’s not working for me on Catalina. I tried this on the latest Catalina beta release (currently beta 5), but the NSWindow window, and thus its delegate, turns out to be null, which then causes my installer to crash with [NSURL initFileURLWithPath:]: nil string parameter when my code calls initFileURLWithPath. As a test, I copied Apple's Installer application (/System/Library/CoreServices/Installer.app) from my Mojave machine to my Catalina machine and launched my installer on Catalina using that, and the crash doesn't happen. The NSWindow and its delegate are not null. Was there a change to the Catalina Installer.app that requires me to update my code? Here’s the code from https://lists.apple.com/archives/Installer-dev/2008/Nov/msg00017.html <https://lists.apple.com/archives/Installer-dev/2008/Nov/msg00017.html> that my code is based off of: #import <Cocoa/Cocoa.h> #import <InstallerPlugins/InstallerPlugins.h> @interface HowToMakeAnAppleEngineerScream : InstallerPane { } @end #import "HowToMakeAnAppleEngineerScream.h" @interface PageController : NSObject { } - (id)distribution; @end @interface IFDocument : NSObject { } - (id)path; @end @implementation HowToMakeAnAppleEngineerScream - (NSString *)title { return [[NSBundle bundleForClass:[self class]] localizedStringForKey:@"PaneTitle" value:nil table:nil]; } - (void) didEnterPane:(InstallerSectionDirection) inDirection { NSWindow * tWindow; PageController * tPageController; tWindow=[NSApp keyWindow]; // This should be improved IMHO tPageController=(PageController *) [tWindow delegate]; if (tPageController!=nil) { NSLog(@"This is the package path: %@",[[tPageController distribution] path]); } } Any help would be greatly appreciated. Thanks in advance. -Lora _______________________________________________ Do not post admin requests to the list. They will be ignored.
