xcode - Core Data Exporting all tables

I have an app that creates individual events and stores them in core data. What I need to do it load one individually and then export it by email. The code below works except it exports every event where I need it to just export the index path selected one. The code does load the appropriate record because the NSLog (@"My record is: %@", currentItem); does display only the settings for that event but when the data is exported to email all events are sent. I need the selected event with the event name to export. Any thoughts?NSInteger index = ex...Read more

XCode: Preprocessor macros from host target not being found in unit tests

In my target setup I have preprocessor macros that set some URLs I use in the my app. I have some integration tests to test server API integrations we've done.

xcode - Finder Style NSSplitVIew - Resize only right panel on Window Resize

However if i expand the form it changes the size of both the Left & Right Views. I want it to default to changing only the Right view. So the user can increase the Left View if she wants but when they resize the form it only resizes the Right View....Read more
