Cocoa Samurai: Singletons: You're doing them wrong

http://cocoasamurai.blogspot.com/2011/04/singletons-your-doing-them-wrong.html

Thursday, April 07, 2011. Singletons: Youre doing them wrong. This post feels a bit odd, as generally I fully agree with Dave Dribin on how wrong singletons are and that you should avoid them if possible. However on Stack Overflow i've seen far too many people write bad code that is horrible for several reasons. Singletons are fairly easy to create. Here is a basic example. MyClass *)singleton { static MyClass *shared = nil; if(shared = nil) { shared = [ MyClass alloc] init]; } return shared; }. This is ...

Cocoa Samurai: January 2012

http://cocoasamurai.blogspot.com/2012_01_01_archive.html

Tuesday, January 31, 2012. Recently I was faced with a dilemma. I was writing code I needed, and then I triggered a Clang Static Analyzer issue. Here is the code a category on NSColor, see if you can figure out whats wrong with it from a Static Analyzer perspective. NSColor *nscolor = [self colorUsingColorSpaceName:NSCalibratedRGBColorSpace];. Nscolor getRed:&components[0] green:&components[1] blue:&components[2] alpha:&components[3] ;. CGColorRef cgColor = CGColorCreate(space, components);.

Cocoa Samurai: November 2010

http://cocoasamurai.blogspot.com/2010_11_01_archive.html

Wednesday, November 17, 2010. OmniWeb as a Cocoa Documentation Browser. The built in Xcode Documentation browser is okay, and the stuff Apple does to bring some bits of documentation lookup into the code in IDE is not bad. However, until the full documentation browser is it's own app, I don't think it'll ever reach its full potential. One day I saw Peter Hosey use OmniWeb and do a brief run through. Of what he did to browse documentation. What's New in Mac OS X 10.6 Notes. My Doc/Code Search Templates.

Cocoa Samurai: August 2010

Wednesday, August 11, 2010. Enumerating Lines Concurrently using a Block. I asked about enumerating over the lines of a string concurrently using a block. I couldn't see an API to deal with this issue directly. If you look through the Mac OS X 10.6 SDK you'll see this. Void)enumerateLinesUsingBlock:(void (NSString *line, BOOL *stop) block. That I should have thought of, but didn't seem obvious at the time till I saw the solution. I was also asked why I didn't do something like. StringArray enumateLinesU...

Cocoa Samurai: Global Keyboard Shortcuts with Carbon Events

http://cocoasamurai.blogspot.com/2009/03/global-keyboard-shortcuts-with-carbon.html

Thursday, March 26, 2009. Global Keyboard Shortcuts with Carbon Events. Not with Cocoa, in its current form it's literally impossible. Here's why Cocoa Events works as such, according to the Cocoa Event Handling Guide. It then goes on. Has a quick entry window which you can invoke from anywhere, applications like Quicksilver. Setting up a project. Now in AppController.m add #import Carbon/Carbon.h and implement -(void)awakeFromNib and you should have. Import AppController.h #import Carbon/Carbon.h. This ...

My little hideout on the net. The Unofficial Apple Weblog. Key-Value Observing Done Right. Again. May 21, 2010 04:36 PM Cocoa. I love using KVO for all sorts of things: side-effect, flagging UI as dirty, resetting caches, …. Writing the observeValueForKeyPath:ofObject:change:context: method has long since become tedious. So I created a TextExpander. Snippet to write it for me. Mike Ash wrote a interesting blog post. Andy Matuschak has proposed a very convenient API. Inspired by Mike's and Andy's writings...

Cocoa Tidbits: March 2009

http://mac-objective-c.blogspot.com/2009_03_01_archive.html

Sunday, 29 March 2009. In an attempt to create a video game, I came across the problem of creating a maze (see figure). Like in most games you need to go from point A to point B via a number of corridors. Now my problem was to find a good algorithm to create mazes, and after some research on the Internet I found several of them (see wikipedia. For an explanantion) . My first attempt was to use the simpelst algorithm , being the Depth-first search. The algorithm goes as follows :. Cell x: x ] ;. MazeCell ...

Cocoa Tidbits: October 2013

Tuesday, 15 October 2013. Mobile Ads do not work (for app developers). In my humble opinion mobile ads just doesn' work for App developers as a mean to generate revenue from their apps. You have an average CTR of 0.21% , but you only get one cent or two cent per click. Meaning that you need millions of viewers per month to get a decent revenue. In my own experience I had an app with AdMob ads, and indeed I got a daily CTR of 0.17/0.2/0.22; much in line with the average CTR found. View my complete profile.

Cocoa Tidbits: June 2012

Saturday, 16 June 2012. It has been ages. Since I published something. But now I'm back, I was too busy with setting up my own business, start developing for iOS 5 and iPad, etc. So it was a very hectic 1 year and a half. I have now 8 apps on the appstore (and 1 under review) and my experiences are mixed , the free ones are very well downloaded , the payed however. Anyway for those who want to know what my apps are here we go :. Same as above is a port from the iPhone version for iOS 5 and higher. Hardco...

Wednesday, 22 April 2009. NSDateFormatter in OSX 10.4.11. Today I found some strange behaviour in the NSDateFormatter :. If I execute the following code :. NSDateFormatter *timeFormatter = [ [NSDateFormatter alloc] init] autorelease];. NSDate *stringTime = [NSDate date];. NSString *formattedDateStringTime = [timeFormatter stringFromDate:stringTime];. TheTime setStringValue: formattedDateStringTime] ;. Then , instead of displaying the time, it shows me the date. If I add the following line on top :. I cop...

ikhoyo: Dynamic Tabs for the iPad

http://ikhoyo.blogspot.com/2011/05/dynamic-tabs-for-ipad.html

App development for the iPhone and iPad. Saturday, May 28, 2011. Dynamic Tabs for the iPad. Each of the detail views will be contained in a UINavigationController. Using some IB tricks, we can put each detail view in it's own xib. As you know if you've read any of my previous posts, I'm a big fan of Interface Builder, and I think you should leverage it wherever possible. In this case we'll be using it wire almost the entire UI, with very little external code needed. Directory and open the ikhoyo-public.

App development for the iPhone and iPad. Friday, July 1, 2011. Networking Library for iPhone and iPad. I've added a very useful and complete networking library to my open source GitHub repo. After you clone the repo. Open the ikhoyo-public workspace in the workspaces. Directory, and then look in the ikhoyo-net project. There is also some example code in the ikhoyo-top project. The sample retrieves some data from Socrata. The example gets some Socrata data and builds a database table using SQLite. Chupamo...
