iphone - How can I center my image in horizontal orientation? -

-

I have an image view that is inside a UIScrollView so that I can pinch & amp; Zoom My portrait looks fine in portrait mode, but when I go horizontal orientation the image is not centered.

The UIScrollView is 320x460.

Here is my code: 

  - (zero) viewDidoadload {[Super Viewedload]; CGRact frame = CGRactam (0, 0, 320, 460); Self.imageView = [[[AsyncImageView alloc] initWithFrame: frame] Autoreshoe]; [Self.imageView loadImageFromURL: self.url]; ScrollView.contentSize = CGSizeMake (self.imageView.frame.size.width, self.imageView.frame.size.height); ScrollView.maximumZoomScale = 4.0; ScrollView.minimumZoomScale = 0.75; ScrollView.clipsToBounds = Yes; ScrollView.delegate = self; [ScrollView adsview: self.imageView]; }

and the UIScrollView delegate method 

  - (UIView *) viewForZoomingInScrollView: (UIScrollView *) scrollView {return imageView; }

How can I focus my image in horizontal orientation?

Try to autorimetry the scroll view: 

 < Code> scrollview.autoresizingMask = (UIViewAutoresizingFlexibleHyight | UIViewAutoresizingFlexibleWidth);

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).
