On El Capitan in Xcode 7 beta using Swift 2.0, I subclassed a NSView to use as a prototype view of NSCollectionView's item view, and override the updateTrackingAreas: method to do the mouse tracking. The NSCollectionView was inside a NSPopover. It seems that only the first 2 times the updateTrackingAreas:...

Newbie question follows... I am learning Objective C based OS X Cocoa app development. Most of the books and videos I have are for iOS, so I am converting some simple iOS code examples to OS X. When I create a new OS X "Cocoa Application" project, with the "use...

I am on Mac OS X Yosemite 10.10 and Python 2.7. If I type the following: du -g -d1 /Users 2> /dev/null in the command line, everything works perfectly. Now, my goal is to use that command in a python script. My idea was to use the following: import subprocess...

When running my code, I am getting a number of 1's printing to the console rather than 1,2,3,4,5.... Some help with why this is happening would be great, I'm having trouble figuring it out. The idea is to loop through the Calendar names until finding the 'Travel' calendar. func checkCalendarExists(){...

How can I add a angle (rotate) my CAGradientLayer? Without rotating my view (self.colorView). I just want to add a angle to the gradient I create my CAGradientLayer like below CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.colors = [NSArray arrayWithObjects:(id)[[NSColor blueColor] CGColor], (id)[self.gradColorTwo CGColor], nil]; gradient.frame = self.colorView.bounds; [self.colorView setLayer:gradient]; [self.colorView...

I'm not even sure if bash is the most proper way to achieve this but, I need to, programmatically, switch between opened applications on OS X. I'm thinking about doing a bash program to execute "cmd+tab". I'm unable to find this on a regular search, so, perhaps someone can point...

I'm trying to generate a static library and link it with an execution binary. This is a library function: #include <stdio.h> int hello() { return 10; } With these commands, I could get a static library. gcc -c io.c ar -crv libio.a io.o With lip -info, I checked it is...

I want to restrict character input on NSTextField, i.e. so that disallowed characters aren't even appearing. Most of what I found about this topic were solutions that only validate after text input finished or using NSFormatter which still allows the character to appear. So far I came up with this...

I've recently installed El Capitan on OSX, which comes with the new San Franciso font as system font. The apple presentation here https://developer.apple.com/videos/wwdc/2015/?id=804 (Bit of an overview here: http://codemotionapps.com/san-francisco-display-vs-text-compact-vs-normal-a-brief-review/) states that, by default, numbers are displayed proportionally. They do allow to switch to displaying them mono-spaced (at least in their...
