  • How to get a reference to a control in the view?

    - by Kevin
    If I have a UIScrollView set up in the view via the Interface Builder, how do I get a reference to it in the ViewController implementation? I want to programmatically add labels to the scroll view. For example, in C# if you have a textbox declared in the UI/form, you can access it by simply using the ID declared for that textbox. It doesn't seem this simple in objective c. Thanks Kevin

  • Why doesn't Apple make private APIs inaccessible?

    - by Howiecamp
    If Apple doesn't want developers using private APIs in the iPhone SDK, why don't they do something like mark the classes and/or methods with whatever the Objective-C equivalent of C#'s "internal" keyword? If the APIs are spread amongst multiple binaries, Apple could refactor them into dedicated private-API-only binaries to make this easier for them.

  • MonoTouch - has anyone used this?

    - by Jonesy
    Hi folks, I'm a .NET developer trying to make the leap into objective-c iPhone programming. I created my first app - just a simple portfolio with multiple xibs. I've just come across MonoTouch which lets you develop iPhone apps in C# or .NET. Has anyone tried this out? I'd be interested to know people opinions on it. Cheers, Jonesy

    - by Sridhar Ratnakumar
    I have a Python2 project with lots of try .. except .. blocks like this: try: [...] except SomeException, e: # do something with `e` To port them all to Python 3 (and still have the code run Python =2.6), I have to manually change each and every one of them to the following: try: [...] except SomeException, e: _, e, _ = sys.exc_info() # do something with `e` Can this be automated using 2to3? If so, how?

  • jQuery; combine user click and :checked

    - by user275074
    I have two blocks of code which basically check for 1) a click event on a radio button e.g. $("input[id='frmSkill']").click(function(){ //do something }); And 2) a block of code to check if a radio button is :checked, if so, then perform some actions e.g. if($("input[id='frmSkill']:checked").val()){ //do something }); What I'd like to do is combine the two in order to reduce the code as the actions performed under each are the same.

  • What's holding up my PHP script?

    - by gAMBOOKa
    We've got a PHP crawler running on our web server. When the crawler is running, there are no cpu, memory or network bandwidth spikes. Everything is normal. But our website (also PHP), hosted on the same server, stops responding. Basically the crawler blocks any other php script from running. What could be the problem? EDIT: ** fsockopen is being used to download files to crawler! **

  • Why don't all XSLT templates get executed at once?

    - by Matt W
    Refer to: http://stackoverflow.com/questions/1613454/retrieving-one-element-and-filter-by-another In the above linked posting, I don't understand why the two template blocks don't get executed upon in the incoming XML at the same time. As far I can can see, the XSL risks the second template executing for every Document element whether it is called with apply-templates or not. Could someone explain this to my stifled brain, please? Thanks, Matt.

  • How do I use the information about exceptions a method throws in .NET in my code?

    - by dotnetdev
    For many methods in .NET, the exceptions they can potentially throw can be as many as 7-8 (one or two methods in XmlDocument, Load() being one I think, can throw this many exceptions). Does this mean I have to write 8 catch blocks to catch all of these exceptions (it is best practise to catch an exception with a specific exception block and not just a general catch block of type Exception). How do I use this information? Thanks

    Which phone should I start developing for? I have no preference for either. I currently own Macbook Pro and I have Windows installed in Boot Camp. I don't know either C# or Objective-C. I am at ground zero in terms of skills required to start developing apps.

  • Alternate three and three rows in a table with jQuery

    - by Frode Lillerud
    I want to set the alternate background color for rows in a table - but the twist is that I don't want every other row to be colored, I want to treat them in blocks of three rows. So for a table with eight rows I want the first three to be white, then the next three to have a background color, and the last two are back to white again. How can I do this using jQuery?

  • How can I generate images of basic figures with Perl?

  • How to create dynamic menulets in OSX

    - by taw
    I want to put a dynamically generated icon (not static image) + possibly a tiny bit of text in OSX menu bar. If possible I'd prefer to do it from Ruby or some other convenient scripting language, but I'll deal with Objective C if that's the only way. How do I do that?

  • Concurrent Linked HashMap java

    - by Nilesh
    Please help me use/create Concurrent LinkedHashMap. As per my belief, if I use Collections.synchronizedMap(), I would have to use synchronized blocks for getter/setter. If I use ConcurrentSkipListMap, is there any way to implement a Comparator to store sequentially. I would like to use java's built in instead of third party packages. Thanks

  • New iPhone Dev policy

    - by milesmeow
    Apple doesn't want anyone to create iPhone apps outside of the Xcode/Objective-C environment. How can they actually reinforce this? If the other IDE's, for example Unity, compiles to an iPhone executable, how will Apple know which dev environment you used to create the app? Can they have Xcode compile some sort of signature into the executable that no one knows about?

    I'm looking for a complete example of using select for update in SQLAlchemy, but haven't found one googling.

How do I do that? As far as I know you need to: begin transaction select ... for update update commit

  • Creating a list of lists with consecutive numbers

    - by Henrik
    I am looking for a convenient way to create a list of lists for which the lists within the list have consecutive numbers. So far I only came up with a very unsatisfying brute-typing force solution (yeah right, I just use python for a few weeks now): block0 = [] ... block4 = [] blocks = [block0,block1,block2,block4] I appreciate any help that works with something like nrBlocks = 4.
