Core Data migration failure between NSPersistenceFrameworkVersions 251 and 358

阅读更多关于 Core Data migration failure between NSPersistenceFrameworkVersions 251 and 358

I have what appears to be a bug with Core Data in OS X 10.7.1. My data store (NSSQLiteStoreType) is not being automatically migrated correctly. As a side note the exact same Core Data models are used by an iOS version of the app. -> Here is what appears to be happening. Up until the latest release everything has been working fine -- I have 14 revisions of the model -- model 13 has been shipping for quite some time without incident. Recently I updated my app and added a new model so I am at 14 (this is the version now used in the shipping apps). The iOS version works just fine when migrating

OSX - Service does not show the localized Menu Title string

阅读更多关于 OSX - Service does not show the localized Menu Title string

I have a Cocoa application. This hooks up into OSX Service Menu. I have created three ServicesMenu.strings for en.lproj , zh-Hans.lproj and hi-IN.lproj for localizing the Service Menu Title. The problem is OSX does seem to be using the localized text at all. Info.plist (relevant portion) <key>NSServices</key> <array> <dict> <key>NSKeyEquivalent</key> <key>NSMenuItem</key> <dict> <key>default</key> <string>CreateHere</string> </dict> <key>NSMessage</key> <string>createHere</string> <key>NSPortName</key> <string>CreateHereFilesService</string> <key>NSRequiredContext</key> <dict> <key

问题 Some C++ application compiled and run seamlessly in OS X Snow Leopard, but I changed recently to OS X Lion, and here, although there is no compilation error, when I try to run it I get the error "Illegal instruction: 4", I have no clue, what could be the reason?

问题 I'm currently working with the XMPP Library for Objective-C, and I'm using the "Desktop" example code. It logs in fine; however, when I open a new chat, or someone sends me a message, it crashes.

What is the best way to setup Django on os X 10.7 Lion?

阅读更多关于 What is the best way to setup Django on os X 10.7 Lion?

I am setting up Python and Django on os X 10.7 from a virgin install and Xcode 4.3. I tried using the default install of Python: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ I normally use a Python based package manager called easy_install. Easy_install seems to not be able to find the compiler. EDIT: When I tried to install MySQL-python I got this error: $ sudo easy_install MySQL-python Password: Searching for MySQL-python Reading http://pypi.python.org/simple/MySQL-python/ Reading http://sourceforge.net/projects/mysql-python/ Reading http://sourceforge.net/projects/mysql

Lion 10.7.3: Apple is not currently accepting applications built with this version of the OS

阅读更多关于 Lion 10.7.3: Apple is not currently accepting applications built with this version of the OS

问题 I was running Xcode 4.2 on Lion 10.7.2 and I have a few applications that needed updating to the Lion sandbox, so I can resubmit them to the Mac App Store (Mac, not iOS). Somewhere along the way I had a popup to update to combo update 10.7.3 and after that everything went wrong. Verifying and submitting apps was fine if the archive was compiled in 10.7.2 but if it was compiled after the 10.7.3 update it can no longer verify the app. That is right, under 10.7.3 I can still verify apps if they

How to setup Xfig onto a Mac machine? [closed]

阅读更多关于 How to setup Xfig onto a Mac machine? [closed]

The user manual said that I need to Get the source of xfig (xfig.3.2.5-alpha3.full.tar.gz) and gunzip and untar the file: Either do: gunzip -c xfig.3.2.5-alpha3.full.tar.gz | tar xvf - or gunzip xfig.3.2.5-alpha3.full.tar.gz tar xvf xfig.3.2.5-alpha3.full.tar It also said that There is a version of xfig ported to run on the MacIntosh under the Darwin port of XFree86. But I didn't find how to setup the XFree86 and even the xfig since I am very new to either Mac OS or UNIX. The easiest way is probably to use a package manager like Macports , Fink , Homebrew etc. For macports the steps are
