I am trying to run SampleFTPExportPlugIn which comes with Aperture SDK 2.1 . I had to configure the Base SDK and manually copy the PluginManager.Framework folder to / Library / Frameworks, as described here .
All compilations and Aperture 3.2.3 now offer the menu item File / Export / FTP.
When choosing the "FTP" export method and thus launching the plug-in code, Aperture crashes with EXC_BAD_ACCESS. Illegal memory is accessed in the initWithAPIManager of the SampleFTPExportPlugIn class when trying to get a link to ApertureExportManager :
_exportManager = [[_apiManager apiForProtocol:@protocol(ApertureExportManager)] retain];
This is the second line that starts after Aperture transfers control to the plug-in and appears to be the standard way to get the ApertureExportManager link in any Aperture plug-in (I have not found any alternative ways to achieve the same).
Here's the stacktrace:
Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: 0x000000000000000d, 0x0000000000000000 VM Regions Near 0: --> __TEXT 0000000100000000-0000000100798000 [ 7776K] rx/rwx SM=COW /Applications/Aperture.app/Contents/MacOS/Aperture Application Specific Information: objc_msgSend() selector name: class objc[3000]: garbage collection is OFF Performing @selector(a_exportPlugIn:) from sender NSMenuItem 0x111d2a540 Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x00007fff8711c090 objc_msgSend_vtable2 + 16 1 com.apple.CoreFoundation 0x00007fff8381e25f -[__NSCFString isEqualToString:] + 63 2 com.apple.PluginManager 0x0000000101211218 -[PROBundleHandler apiForProtocol:] + 109 3 com.apple.CoreFoundation 0x00007fff83852f4c __invoking___ + 140 4 com.apple.CoreFoundation 0x00007fff83852de4 -[NSInvocation invoke] + 132 5 com.apple.CoreFoundation 0x00007fff83852fb4 -[NSInvocation invokeWithTarget:] + 52 6 com.apple.CoreFoundation 0x00007fff8384dff4 ___forwarding___ + 756 7 com.apple.CoreFoundation 0x00007fff8384dc88 _CF_forwarding_prep_0 + 232 8 com.apple.SampleFTPExportPlugIn 0x000000012c0d5361 -[SampleFTPExportPlugIn initWithAPIManager:] + 209 9 com.apple.PluginManager 0x000000010120c6fa -[PROConcretePlugIn plugInInstance] + 212
I read all about Objective-C memory management, but can't figure it out. All other examples that I found on the Internet are implemented that way, so I assume that I have a compatibility problem, something is missing in my Aperture / Library installation. How can I narrow the problem?
EDIT:
The problem seems to be related to the passed in apiManager. Method Signature:
- (id)initWithAPIManager:(id<PROAPIAccessing>)apiManager
This parameter is then assigned to our internal link:
_apiManager = apiManager;
However, the actual class passed is equal to PROPlugInFirewall , as this output is repeated:
NSLog(@"_apiManager class is: %@", [[_apiManager class] description]);
Then calling respondsToSelector also fails, although this method is inherited from NSObject.
if ( [_apiManager respondsToSelector:@selector(apiForProtocol:)] ) { NSLog(@"responds"); }
_ApiManager itself describes itself as:
_apiManager is: <[*<PROBundleHandler: 0x14d79130> (PROAPIAccessing)*]>
Still stuck ...
EDIT:
So it looks like Aperture is passing a pointer pointing to nirvana ... However, I just installed another plugin from the Apple web page, with the installer and everything else. It also did not work out when called ...
