iPhone, How do I rotate an UIImageView around a point using Core Animation and CATransform3D? -

-

This is what I want to do: 

  (1) (2) | / | / | / | I want to transfer a UIImageView equivalent to the point (2) around the position (2) to the position of a clock pin (width: 9px, height 73px) (/) / (3)  
 My DegreeToRadians defined the macro as follows: Received:  
  #define degreesToRadian (x) (M_PI * (x) / 180.0)  
 
 / * kmPointer is UIImageView * / 
   NSValue * value = zero; CABasicAnimation * Animation = Zero; CATransform3D conversion; Km Pointer.lier.techpoints = cp pointmake (0, 0); [Kmpointer. Remove LayerAll Animation]; Animation = [with CABasic Animation Animation: @ "Transform"]; Transform = catariform 3dmacrotation (degree trouadian (30), 0.0 f, 0.0 f, 1.0 f); Value = [NSVLite valueWithCatransform3D: Transform]; [Animation Setup: Value]; Transform = cateriform 3dmacrotation (0.0 F, 0.0F, 0.0F, 1.0F); Value = [NSVLite valueWithCatransform3D: Transform]; [Animation setfavalvalue: value]; [Animation setautoorswords: no]; [Animation set duration: 1.0f]; [Change animation set count: 1]; [KmPointer.layer addAnimation: animation fork: blue];

How can I turn the pointer around a star marked with (3)?

Apple docs shows anchor point image for OSX This looks for iOS:

Then try setting your anchor point to 0.0, 1.0.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
