Re Singleton Help ...

I had a very similar situation using a singleton and found that I needed to remove it from the notification centre before the app died - or landed up with an odd side effect (main menu items in xCode would no longer respond to the mouse ). I fixed it by getting the app delegate to respond

Re: Need localization-proof method of transporting dates

Strange error message when trying to print

When I try to print a document ( to PDF ) the app can sometimes hang - and I get a long message which looks like debug printout from the OS in the debug console. The last section of the message seems to contain the crux of the problem : - Sun Apr 26 12:42:51 peter-hudsons-macbook-pro.lo

Attributed strings - and bounding rects

Thanks to both of you for helpful code. I’m still not out of the wood yet though. Insofar as I can now determine the size of the rect to hold the attributed string, I can’t write it to the cell correctly. This is what i do :- // aString is a preprepared attributed string // Determine the he

Yes, you've got the page I thought may be helpful. I hadn't really suggested it as a considered solution to your problem. I just thought I'd mention it in case you hadn't come across it. Peter > On 9 Mar 2017, at 23:43, Daryle Walker wrote: > > >> On Mar

Weird pointer change...

macOS 10.12.3 Xcode 8.3 I have a very strange problem I have never come across before. I open I file in my application, do a few typical operations in it - and then shut the file. I then open another file - and do a few typical operations in it. The app then grinds to a halt with an illega

Debugging strange memory ( ? ) problem

Hi all I have a strange memory problem. My app is a typical document based app. I have one method which checks on the indexes of selected rows in a table view frequently. After this method has been called ( without a problem ) many times, the app grinds to a halt - and points the finger at t

xCode troubles

Hi All xCode has just decided ( for the 20th time this week ) that I don’t deserve any UI tools in Interface Builder - as in the panel on the right hand side of the main window. I have tried everything I can think of to try to get them back - like restarting xCode, opening different files etc.
