Most likely. Just use the command line application `class-dump` to view the private headers. Note that your app will be rejected from the App Store for linking to private frameworks if you link at compile. It is easy enough to see that you are linking the private frameworks by running `otool` on your binary if linked at compile. 

These are the compilable headers generated by [class-dump-z][1], a iOS class dumper:

I need to use chmod to change all files recursivly to 664. I would like to skip the folders.
I was thinking of doing something like this

    ls -lR | grep ^-r | chmod 664

This doesn&#39;t work, I&#39;m assuming because I can&#39;t pipe into chmod
Anyone know of an easy way to do this?

Thanks

Can ASP.Net routing (not MVC) be used to serve static files?

Say I want to route

    http://domain.tld/static/picture.jpg

to

    http://domain.tld/a/b/c/picture.jpg

and I want to do it dynamically in the sense that the rewritten URL is computed on the fly. I cannot set up a static route once and for all.

Anyway, I can create a route like this:

    routes.Add(
      &quot;StaticRoute&quot;, new Route(&quot;static/{file}&quot;, new FileRouteHandler())
    );

In the `FileRouteHandler.ProcessRequest` method I can rewrite the path from `/static/picture.jpg` to `/a/b/c/picture.jpg`. I then want to create a handler for static files. ASP.NET uses the `StaticFileHandler` for this purpose. Unfortunately, this class is internal. I have tried to create the handler using reflection and it actually works:

    Assembly assembly = Assembly.GetAssembly(typeof(IHttpHandler));
    Type staticFileHandlerType = assembly.GetType(&quot;System.Web.StaticFileHandler&quot;);
    ConstructorInfo constructorInfo = staticFileHandlerType.GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, null, Type.EmptyTypes, null);
    return (IHttpHandler) constructorInfo.Invoke(null);

But using internal types doesn&#39;t seem to be the proper solution. Another option is to implement my own `StaticFileHandler`, but doing so properly (supporting HTTP stuff like ranges and etags) is non-trivial.

How should I approach routing of static files in ASP.NET?

What is the `-(void)viewDidUnload` is good for?

Could I not just relase everything in `-dealloc`? If the view did unload, wouldn&#39;t `-dealloc` be called anyway?


When should I release objects in -(void)viewDidUnload rather than in -dealloc?

this was the answer from the brad larson on this
[SO][1] question
	

If you add two breakpoints, you should be able to debug these exceptions. To do this, go to Run | Show | Breakpoints and create two global breakpoints (I do them globally because they are so useful in all my applications). The first should be named &quot;objc_exception_throw&quot; and its location should be &quot;libobjc.A.dylib&quot;. The second should be &quot;-[NSException raise]&quot; and its location should be &quot;CoreFoundation&quot;.

Now, if you start debugging your application with breakpoints enabled, it should break on the throw of these exceptions. You should then be able to see the chain of events that led to the exception within the debugger.

now in this answer i want to ask how do i add location mentioned???

Apple&#39;s iPhone apps such as Music and Contants use a search bar in a UITableView. When you scroll down so that the search bar moves down, the empty space above the scroll view&#39;s contents has a light gray background color (see screenshot).

![Screenshot of Contacts app showing light gray background][1]

(Notice that the search bar has a slightly darker edge line at its top. This is not there for the default UISearchBar, but subclassing should take care of that.)

I tried setting the background color of the UITableView, but that affects the rows as well. Does anyone know how to achieve this effect? Am I going to have to override implement drawRect: or is there a built in way?

I&#39;m familiar with using Google Maps Javascript API. Recently I started using MapKit framework for an iphone project, but I&#39;m having a hard time to figure out zooming and setting a region on map.
 
In Google Maps API I used to use integer zoom levels like 8, 9, 10 along with straightforward function setZoom(). The only equivalent method I can see in the MapKit framework is setRegion:animated. As I understand, I need to set a region&#39;s span&#39;s latitude and longitude &quot;delta&quot; values to specify zoom level. But I really don&#39;t have an idea what these values represent(I read the documentation).
 
When I use a MKMapView delegate and trace the span values in regionDidChange delegate method results don&#39;t seem to correlate each other. It&#39;s ok when I zoom out and see the span delta values are increasing as specified in documentation. But suddenly I drag the map without zooming and delta values become 0.0. 

Can somebody please explain what is the reference point to these span and delta? Or is there any algorithm to convert an integer zoom level(like 9) to these delta values? 

As a bonus question is there any way to specify a minimum-maximum zoom level on a MKMapView :) 

Thanks

I am working on a large project involving creating a worldwide hotel database with rich data such as Addresses, Images, Descriptions, Policies, Coordinates, Facilities, Reviews, Local area descriptions and their amenities etc.

I am looking for a public hotel API where I can both retrieve the data and run (preferably RESTful) real-time queries for specific locations and available rooms, and where I can subsequently let my customers make bookings.

Can anyone share experience, knowledge and possible guidelines for such a project, which APIs are suitable and what are the best practices?

I&#39;ve recently read a lot about software (mostly scientific/math and encryption related) that moves part of their calculation onto the GPU which causes a 100-1000 (!) fold increase in speed for supported operations.

Is there a library, API or other way to run something on the GPU via C#? I&#39;m thinking of simple Pi calculation. I have a GeForce 8800 GTX if that&#39;s relevant at all (would prefer card independent solution though).

**What classes of the Java Standard API can cause memory leaks when used in an (not obviously) incorrect way? And how can these memory leaks be avoided/fixed?**

**Example:** `ObjectInputStream` and `ObjectOutputStream` keep references to all objects they have seen in order to send subsequent occurences of the same object as references rather than copies (and thereby deal with circular references). This causes a memory leak when you keep such a stream open indefinitely (e.g. when using it to communicate over the network).

**Fix:** Call reset() periodically or after each top-level object.

With iOS 4 coming out soon, I have already planned to include an iAd in a future update of an app of mine. I assume that this will make my app unusable for anyone on a firmware lower than 4.0. Is there a way to change those variables and the .xib file based on the user&#39;s firmware?

In iOS 4.0 Apple has redesigned the backup process.  

iTunes used to store a list of filenames associated with backup files in the Manifest.plist file, but in iOS 4.0 it has moved this information to a Manifest.mbdb

You can see an example of this file by making a backup with your iOS 4.0 devices and looking in your ~/Library/Application Support/MobileSync/Backup folder (Look inside the subfolders with the most recent date)

Here&#39;s a screenshot of what the file looks like in a text editor:

[![alt text][1]][1]  
&lt;sub&gt;(source: [supercrazyawesome.com](http://supercrazyawesome.com/images/mbdb.png))&lt;/sub&gt;

I am trying to implement a game using the iPhone OS 4.0 (iOS4?) SDK. In the previous versions of the SDK, I&#39;ve been using the [UIView beginAnimations:context:] and [UIView commitAnimations] to create some animations. However, when I look at the documentation of the functions in 4.0, I see this comment.

&gt; Use of this method is discouraged in
&gt; iPhone OS 4.0 and later. You should
&gt; use the block-based animation methods
&gt; instead.

You can find it here:
http://developer.apple.com/iphone/library/documentation/uikit/reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/clm/UIView/commitAnimations

My question is, what are block-based animations in iPhone OS 4.0? I though that the beginAnimations:context: and commitAnimations functions were used to create animation blocks..

I created this community wiki to bind together a number of
other Q/A&#39;s I&#39;ve seen here on SO. If you&#39;re here, you&#39;ve probably
installed the final version of Xcode 3.2.3 with iPhone SDK 4 ([download
link][xcode_download], reg reqd), and then encountered one or both of these problems:

* In your previously working Xcode iPhone project, you get &quot;Base SDK Missing&quot; somewhere. Something like this:
 
 ![Ruh-roh!][base_sdk_missing_image]
 
* In a related but more general observation, none of the previously available panoply of Device or Simulator SDK choices (e.g. 3.0, 3.1, 3.1.3, ...) is available where you used to see them.

I have written a pretty extensive REST API using Java Jersey (and JAXB). I have also written the documentation using a Wiki, but its been a totally manual process, which is very error-prone, especially when we need to make modifications, people tend to forget to update the wiki.

From looking around, most other REST API&#39;s are also manually creating their documentation. But I&#39;m wondering if theres maybe a good solution to this.

The kind of things which need to be documented for each endpoint are:

 - Service Name  
 - Category
 - URI 
 - Parameter
 - Parameter Types
 - Response Types
 - Response Type Schema (XSD) 
 - Sample requests and responses
 - Request type (Get/Put/Post/Delete) 
 - Description
 - Error codes which may be returned


And then of course there are some general things which are global such as

 - Security
 - Overview of REST
 - Error handling
 - Etc


These general things are fine to describe once and don&#39;t need to be automated, but for the web service methods themselves it seems highly desirable to automate it. 

I&#39;ve thought of maybe using annotations, and writing a small program which generates XML, and then an XSLT which should generate the actual documentation in HTML. Does it make more sense to use custom XDoclet?


How to automate documentation of a REST API (Jersey Implementation)

I&#39;m going to design a RESTful API soon, thus I need to describe it in order to enable other people to start implementing clients using it. 

I&#39;ve looked around a bit, but unfortunately, I&#39;ve not found any standardized form of describing web-based RESTful services. What I&#39;am looking for is something like JavaDoc, although it don&#39;t have to be generated out of any sort of code. I&#39;m also not talking about something like WADL, I rather want to have some human-readable documentation I can hand out.
 
Due to the nature of RESTful web-based services, it should be quite easy to standardize a documentation. It should just list available ressources, corresponding URIs, allowed methods, content-types and describe the availabe actions. Do you have any suggestions therefore?

Thanks in advance &amp; Greets
 

RESTful API Documentation

I&#39;m trying to do some class inheritance in Python. I&#39;d like each class and inherited class to have good docstrings. So I think for the inherited class, I&#39;d like it to:

* inherit the base class docstring
* maybe append relevant extra documentation to the docstring

Is there any (possibly elegant or pythonic) way of doing this sort of docstring manipulation in a class inheritance situation? How about for multiple inheritance?

Inherit docstrings in Python class inheritance

We are currently using DoxyGen to document code written in C/C++, PHP and Java. To have a consistent environment it would be nice to use it for C# documentation as well.

However we are wondering:

- Do you see any advantages in the generated documentation layout or structure using something other than DoxyGen? We are generating documentation for external developers who are experienced with C# and the .NET platform. Maybe they are used to a certain documentation format?
- How well integrated can DoxyGen be with Visual Studio? Is there something which enables a one-click generation of documentation from inside the IDE?
- Is some other documentation system more integrated with Visual Studio?


Visual Studio with DoxyGen for documentation, or should we use something else?

Ok, so I&#39;ve read both [PEP 8][1] and [PEP 257][2], and I&#39;ve written lots of docstrings for functions and classes, but I&#39;m a little unsure about what should go in a module docstring.  I figured, at a minimum, it should document the functions and classes that the module exports, but I&#39;ve also seen a few modules that list author names, copyright information, etc.  Does anyone have an example of how a good python docstring should be structured?
