What is the best way to open a HTTPS connection?

What is the best way to open a HTTPS connection and retrieve the content as XML? This is how most of the online API is done nowadays, how can this be done on the iphone SDK?
Thanks

Have a look at the SeismicXML example that comes with the iPhone SDK. It uses http instead of https but it may work for you.
You can also look at the NSURLRequest and NSURLConnection classes.
Enjoy.

  • What is the best way to open emails and attachments without using wifi?

    For I-phone and I-pad, what is the best way to open emails and attachments without using wifi?  I turned off wifi in my settings but my boss thinks there may be another way and a better way to use something else instead of wifi.  Any help would be appreciated!  Thank you!

    Thanks!  That is a very good question you post.  My boss asked me that and I am assuming that he is having issues with using wifi wherever he is at.  My boss is the kind of person that when he asks something you look into it and ask him no questions...he's the only one asking questions!  But thank you for your response I will tell him the information you told me and hopefully that will help!

    DO NOT delete files in your Home Folder -> Library tree as there are things like your iPhone backups, your email messages, your application preferences, etc...
    DO NOT delete files outside your home folder, as you may end up deleting something essential to Mac OS X, and turn your Mac into an expensive “Door Stop”.
    I will point out that you will find some very large files in private -> var -> vm (these are the Mac OS X virtual memory paging files (swapfiles) and where Mac OS X stores the copy of RAM when your Mac is put to sleep).  The swapfiles get deleted on reboot, and the sleep image is just going to be created again when you put your Mac to sleep.
    If you think you have found something to delete outside your home folder, it would be best to ask first before deleting.  There are many examples of people deleting files outside their home folder, or renaming files, or changing the ownership or permissions of files, and then their Mac stops running.  Do not be one of those people.  Ask first.

  • What is the better way to open and close connection in bean

    Hello, may i ask about the best way to open and close the connection?
    At the first, the connection code is store in Conn class bean. The JSP page will call a method in Process bean to process the query and update of database. the Process bean is using th Conn to connect to database.
    In my process bean, it have a method for each type of sql like select, insert, update, and delete for each tables. Each method will call the Conn to open and close the connection. The jsp page can simply call a method retrieve or update records.
    However, when calling the processUpdate method, it is a method that update a group of tables base on the query result of another group of tables and calculation. If I calling the query method in the same bean file, it will open and close the connection many times (more than 1000 times). After open and close the connection several times, the connection to mySQL will be fail.
    Currently, i include 2 method in Process that is only calling the Conn to open the connection and close connection. When calling the openConnection method, it will also set the boolean connected in the class to true and call Conn to open connection. When calling the closeConnection method, it will also set the boolean connected in the class to false and call Conn to close connection.
    After that, i add some change to the query method which is when the connected is false, it will open the connection by calling the Conn and close the connection themself. If the connected is true, it will not call the Conn to open and close the connection because it already connected to the database.
    Now, i when i calling the query method in jsp, it can open the connection and close the connection individually. When i call the processUpdate in the jsp, this method will calling the openConnection before calling the query and calling closeConnection at the end. It not only faster the process(less open and close), it also no cause the connect to mySQL fail error again. However, it also make the coding in the bean file more longer and complex.
    Is there have any better solution?

    Use connection pooling. This will put the connection management in the hands of the webserver, not your code. Check out this post:

  • What is the best way to make a HDMI connection?

    I have a 13" Macbook Pro, bought in late 2011, therefore I have the Thunderbolt port. I do not think it has a mini DVI port. Therefore my question is what is the best way to connect this great Mac to a HDTV using an HDMI port on the TV?

    To connect MBP to HDMI monitor or TV via Thunderbolt port, use mini DisplayPort-to-HDMI adapter and HDMI cable. Thunderbolt port is mini-DisplayPort compatible. If you get the adaptor that supports video and audio signal, both will be forwarded to your monitor or TV. Search the Apple store.

    Hi,
    No, Below is a bit from the Session Manager Help
    Currently, Session Manager supports the following instrument session types:
    IVI Sessions—Use an IVI session to obtain the C-based instance handle for an IVI logical or virtual instrument name. NI Session Manager does not support IVI-COM drivers at this time. When IVI-COM drivers are available, you can use an IVI session to obtain an ActiveX interface reference to an IVI-COM driver.
    VXIplug&play Sessions—Use a VXIplug&play session to obtain a C-based instance handle for a VXIplug&play logical or virtual instrument name. Configure VXIplug&play names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
    VISA Sessions—Use a VISA instrument session to obtain a C-based viSession handle to a VISA resource or logical name. Configure VISA logical names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
    Custom Sessions—Use a custom session to create a data container object that shares ActiveX objects you create or other data between software components you write. Use the Attach and Get methods to attach data to and retrieve data from a session. A custom session does not initialize, close, or own an instrument handle. The data you share with a custom session does not have to be instrumentation related. You can create a custom session with any name you request.

  • What's the best way to deal with db connections?

    There are a few ways to do this, I'm wondering what's the most accepted / standard way.
    I have a DBConnection object which hands out Connection objects.
    When each jsp page is loading, every function which requires db access could request its own Connection. Downside to this is...if there are 4 or 5 spots on the same page which require db access, that's 4 or 5 seperate connections that need to be established and then closed.
    Another way I suppose would be to, at the top of each jsp page, create one Connection object, and pass it as a parameter to every spot on the page that needs access to the database. Then at the bottom of each jsp page, I'd close that one Connection object. This means practically every method of every java class I have would need to take a Connection object as input.
    What other methods are there? I think I'm going to go with the 2nd one above, but...it just seems tedious to add "Connection conn" as input to every method. I should add also that most if not all methods that access the database are static, and are called from jsp like...<% SomeClass.login(user); %>...for example.
    I suppose to avoid having to add a Connection object parameter to each static method, I could make all the methods non-static and create instances of the classes I need to work with. In doing so, I'd set a Connection instance variable once for that instance of the class and each (now non-static) method would just use that like...<% Connection conn = DBConnection.getConnection();
    SomeClass sc = new SomeClass(conn);
    SomeOtherClass soc = new SomeOtherClass(conn);
    sc.login(user);
    soc.save(user); %>There are a lot of different ways to accomplish what I'm trying to do. Which have you seen to work best?

    Use the application server database pooling services to create a datasource that can be access using JNDI.
    Move the database access code to a Servlet so that a JSP submits a form to the Servlet that does the database access and packages the data into a bean which is passed to another JSP to be displayed.

  • What's the best way to contact adobe for Connect help?

    We have a cloud account and 50 hosts and would like a simple way for all  to access support  city.adobeconnect.com - we cant work out what  help are we paying for and how do we get to it?
    Is there one number we can ring or one email to use? We find it a maze web pages, blogs and forums and then hit an enterprise type interface - but can we use it?
    If anyone has cracked it - please share your system with us.
    Sandra at City Univeirsty London

    Sandra,
    City University London should have purchased through a reseller, and they would be the best to reach back out to regarding your current licensing, what you are trying to do and how best to match them up. I'd be happy to have an email conversation off-forum (jorma_at_realeyesconnect.com), but since I'm a US reseller, I'm not sure how much I could help, other than giving some guidance on what licensing to request from your local reseller.
    You can find the EU partners here: http://www.adobe.com/products/adobeconnect/strategic-partners.displayTab2.html
    I would recommend Collaborate or MeetingOne to start with, if you don't have a current reseller relationship, as they are both good companies to work with.

  • What is the best way to open a .sit file?

    I downloaded my first .sit file today and thought double-clicking on it would open it with Stuffit Expander (which I also thought was included software, but apparently not -- at least not according to Spotlight). Instead, it for some reason defaulted to Microsoft Word to open it. Since the .sit file is a program that of course didn't work.
    When I checked VersionTracker I noticed that Stuffit Expander has a pretty mediocre user rating.
    *Is there a preferred way to expand .sit files?*
    Replies appreciated.

    Expander has been working great for many years. Has something changed?
    I don't know but its MacUpdate rating is 3 stars (out of 5) and its VersionTracker rating is 2 stars (out of 5), so I concluded there must be something about it people aren't happy with.

    Hi Shane.  Not much in the way of thoughts - - but fwiw:
    How is the drive attached?
    Can you open large files on the drive with other programs?
    Are you running any drive compression or acceleration programs (some drives arrive with these installed)?
    Can you reformat the drive and try again?
    Hi Kirby,
    I attached the UltraMax Plus with a USB cable. The UltraMax powers the cable so power is not an issue. I can open other files. Also, there is 500GB of files on the drive so I cannot re-format it. Although, I noted I could import the entire Aperture Library. However, I do not want to create a duplicate on my machine because that would be defeating the purpose of the external drive.
    Thanks,

    Once the user has entered the URL they want to add to the form. You can use the loadXML function to implement some special text in a label...
    var linkValue = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><exData contentType=\"text/html\" xmlns=\"http://www.xfa.org/schema/xfa-template/2.8/\"><body xmlns=\"http://www.w3.org/1999/xhtml\" xmlns:xfa=\"http://www.xfa.org/schema/xfa-data/1.0/\" xfa:APIVersion=\"Acroform:2.7.0.0\" xfa:spec=\"2.1\"><p style=\"font-weight:bold;text-decoration:none;letter-spacing:0in\">The new link the user have entered is:<a href=\"" + textfield.rawValue + "\">textfield.rawValue</a></p></body></exData>";

  • I am trying to rebuild my iPhoto library and noticed my backup contains aliases (pointers?) and not the actual file. What's the best way to rebuild my library?

    I am trying to rebuild my iPhoto library and noticed my backup contains aliases (pointers?) and not the actual file. What's the best way to rebuild my library?
    Facts:
    In moving to a new iMac, I copied the iPhoto library to an external HDD assuming that I would point the new iMac to the backed up iPhoto Library
    All worked fine when I pointed the new library but noticed that some folders contained aliases and not the original file. So when I attempt to open that photo it can't find it because the alias is pointing to another drive.
    I do have all original photos from a couple of external HDDs. In the folders titled, "Originals" (from older versions of iPhoto) and "Masters" (from current iPhoto)
    I'm thinking I can create a new folder and drop the original files and make that my new iPhoto library. Is there a better way to rebuild my library? I do not want to create any future aliases.
    Thanks in advance for any help!

    do you have a strongly recommended default "managed" library (the iPhoto preference to "copy imported items to the iPhoto library is in its checked state) or a referenced library - you have unchecked that option?
    It sounds like you have a referenced library and are now experiancing one of the very siginificant drawbacks of a referenced library and one of the many reasons they are strongly not recommended
    Also note that iPhoto '11 may use alises in the originals folder as part of the upgrade
    It is important that we understand exactly what you have and what is not sorking - what error messages you are getting
    You must NEVER make any changes of any sort to the structure of content of the iPhoto library - there are no user servicable parts in it  --  and you can not rebuild yoru librtary - only iPhoto ir iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -  can rebuild a library unless you are a SQL programmer and understand the structure that iPhoto uses
