iphone - UiViewController Loading/Unloading -

-

I have a rootview controller, and many view controllers are pressed in the same way as i.e 

  - (IBAction) newWorkoutButton {[auto current model view controller: new workout view controller animated: yes]; }

When a user presses the back button, the current view controller backs the previous view controller i.e. 

  - (IBAction) back button {[self buffer model View controller permission: yes]; }

The problem is, I want to see the View Controller for UPS when pressing the backbutton. They do not take off at the moment because when I go back from them, they are still in the last position.

Regards, Stephen

You can set up the root view controller in the delegate The child's view is unloaded on the child's scene and scene, remove it from supervision. The second and the easiest option is to put it again by pushing the subviews and adding it as a child (put it in the index of the sub-array which was added to the final version of that child)

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).
