Qmind 0.0.10
Over the last two weeks I found some time to work on my small Cocoa project Qmind, a mind-mapping app for OS X:
Finally, arrow keys can be used to change the selection. And icons can be inserted. However, the deletion of icons will come in version 0.0.10 + X, where X > 0.

Node.js Static HTTP Server
Since http://qvacua.com consists of only static files, the following node.js static HTTP server comes in handy
HOST = null; // null => localhost
PORT = 8000;
HTTP_STATUS_OK = 200;
HTTP_STATUS_NOT_FOUND = 404;
var http = require("http"),
url = require("url"),
path = require("path"),
fs = require("fs");

Mocking Class Method in Objective-C
Once in a while, when testing your Objective-C code, you want or have to mock a class method. Or you want to replace the implementation of a class method. The following code replaces the implementation of originalClassMethod of SomeClass with the implementation of mockClassMethod of MockClass:
Method mockMethod = class_getInstanceMethod([MockClass class], @selector(mockClassMethod));

Continuous Integration for Cocoa Reloaded
First do the following:
Open the “Manage Schemes…” dialog and check “Shared” for schemes you want to have available for Jenkins. Xcode generates “xcshareddata” folder inside the xcodeproj file.
Open “Build Settings” for the test target and set “Bundle Loader” and “Test Host” to blank by deleting them.

New Objective-C Boxing Rocks!
The new boxing feature of the Objective-C runtime rocks! In tests, for instance, I don’t have to write
assertThatBool([obj someBoolReturningMethod], equalToBool(YES));
but I can write the following
assertThat(@([obj someBoolReturningMethod]), is(@(YES)));
Note that I’m using OCHamcrest or my fork which can handle NSSize, NSRange, NSRect and NSPoint. My fork is probably broken for...

Outdated: See Continuous Integration for Cocoa Reloaded
Some time ago, I wrote about how to use Jenkins for Cocoa/iPhone projects. Back then, I used GHUnit which can produce JUnit test results XML files. Recently, I found OCUnit2JUnit which converts OCUnit results to JUnit result XML format. Thus, no more GHUnit. Do the following
xcodebuild -target NAME_OF_TARGET -configuration Debug clean test...

How to Use Subprojects with Xcode and Jenkins
Assume, you have an Xcode project Parent and another project Child, which is registered as a subproject of Parent. Let’s further assume that Child is registered as a Git submodule of Parent. Imagine that you want to use Jenkins for continuous integration for the project Parent. Do the following:
Make sure that xcuserdata folder in Parent.xcodeproj is included in the Git repository.

Ein beachtenswerter Fund der CRP-Studie fand in den deutschen Medien erstaunlicherweise jedoch gar keinen Nachhall – die Deutsche Telekom ist, hinter der Bayer AG, der größte deutsche finanzielle Unterstützer der Republikaner. Dies ist besonders pikant, sind die Republikaner doch aus europäischer Sichtweise vor allem wegen ihrer teils reaktionären, an die...

Auto Save and Versions
Auto Save and Versions seem only to work in conjunction with the NSFileWrapper-using read/write method of NSDocument, ie
– readFromFileWrapper:ofType:error:
– fileWrapperOfType:error:
If you use only
– readFromURL:ofType:error:
– dataOfType:error:
then you get a warning that the file cannot be autosaved after having done the following:
Restore a version of the document

Argument Captor for Objective-C
For my small projects Qmind and Qdesktop I needed a Objective-C counterpart of Mockito’s ArgumentCaptor. As far as I can see, OCHamcrest or OCMockito do not offer this functionality. Thus, I wrote an OCHamcrest matcher which does the job: ArgumentCaptor.zip
Example:
ArgumentCaptor *captor = argCaptor();
[someMock someMessage:someArgument];
[verify(someMock) someMessage:captor];

Qvacua is online!
The only Mac app you can download there is Qdesktop. Version 0.0, so, don’t expect too much. It lets you set an arbitrary web page as the desktop background of the main screen. Multi-screen support is to come. You can also use the file://... URLs to load offline web pages (or animated GIFs!). To interact with the web page, select “Toggle Background” from the...

Old and New Display Panel of Munich Subway
Old:
New:
The new version shows more useful information, for example how long you have to wait for the next, next^2 and next^3 train. However, visually, I prefer the old one. Beautiful fonts, the shape being warmer, more appealing for my taste. The new version is too plain and cold. It kind of reminds me of Windows or the infamous BSOD.

AppCode, OCUnit, GHUnit, CI and All That
Outdated: See Continuous Integration for Cocoa Reloaded
I am using AppCode for not-so-daily Cocoa coding sessions. Therefore, I want to use its nice OCUnit integration—similar to the JUnit integration of IntelliJ. At the same time, I do not want to give up the CI integration of GHUnit. To combine both, I did the following.
Set up your GHUnit target denoted by ghunit.

Analyzing Objective-C Code Using Jenkins

Using Jenkins, you can automatically execute Clang’s static analyzer each time you commit to your local Git repository.
First, download the binary files, unpack them somewhere and install the Clang Scan-Build Plugin in Jenkins. Then, create a new free-style job with the following
