TTWordPress – a Three20 library to display a WordPress blog in an iOS app

TTWordPress is a library I wrote to easily display a WordPress blog in an iOS app.  I originally wrote it for the Visionary.ie app and was then able to expand on that to create the Broadsheet.ie app.  Since I found it useful, I thought I’d release it into the wild and see what happens.

To provide the data from a WordPress blog is a nice machine readable format, the excellent JSON API plugin is used.  Obviously, it needs to be installed for the iOS to be able to retrieve anything but that’s a trivial matter.  If you want users to be able to comment on posts, you need to activate the ‘Respond’ controller in the API settings.  On the iOS side of things, the library uses Three20 for the consuming the JSON and displaying the information in tables.

To use the library in your own app, you first need to add Three20 to your project (if you’re not already using it).  Open the example TTWordPress project and copy the WordPress folder and all its contents to your project.

To point the library at your own blog, you need to edit the following line in TTWordPress.h:


#define WP_BASE_URL @"http://ttwordpress.karlmonaghan.com/"

In this file, you can also change the default title for the latest posts view and the way dates are displayed for posts and comments.

Then in your AppDelegate, add the following includes:

#import "WordPressBlogViewController.h"
#import "WordPressAddCommentViewController.h"

Then add the following lines:

[map from:@"tt://examplepostlist" toSharedViewController:[WordPressBlogViewController class]];
[map from:@"tt://blog/author/(initWithAuthorId:)" toViewController:[WordPressBlogViewController class]];
[map from:@"tt://blog/category/(initWithCategoryId:)" toViewController:[WordPressBlogViewController class]];
[map from:@"tt://blog/post/comment/(initWithPostId:)" toModalViewController:[WordPressAddCommentViewController class]];

The first line sets the path to a view controller that will list the latest posts from your blog, the second shows the posts belong to a particular author, the third from a particular category and the fourth is the modal pop up for making a comment.  The assumption here is that the list of posts from your blog will be a tab in your app hence being a shared view controller as opposed to the other two which are created and destroyed on demand.

The final step is to call the latest post view controller from somewhere.  In the sample project, it’s added to the UITabViewController. Once you’ve done that, compile and run your app and you should see your blog posts.

The code is available via a Git repo at https://github.com/kmonaghan/TTWordPress.

If you do use it, I’d love to hear from you.

The icon used is from the excellent Glyphish set.

Pint of Plain V2.0

Last week, the V2.0 of my Pint of Plain app was approved for sale on the Apple App Store.  It’s a major update of the app, with most of the code base completely rewritten.  I think this version is a vast improvement on V1.2 and I’m planning a few more updates once I get some free time again.

What’s been interesting (for me anyway) to see over the last week is the number of people that download the update.  From what I’ve seen from previous updates, the bulk of users will update in the first week and then a trickle after that (in a classic long tail style graph).  Since it was approved, there’s been 1,144 downloads.  This compares to about 10,000 total downloads since the app was released in December ’09.

It’s a useful app to test out various libraries I come across so I decided I’d mention the ones I used this time around.

Three20

The core functionality of the app uses the fabulous (if a little delicate) Three20 library.  Using the table classes and JSON library meant I could quickly rebuild the primary screens of the app.  The crowning glory though is the photo gallery.  It’s pretty straight forward to add a slick gallery once the images have been pulled from the API.

I have been frustrated though that when a new version of Xcode is released, the library needs tweaking before it works again.  There’s been promises to improve this in future releases, so fingers crossed there.

The lack of documentation is a hinderance as well.  This is mitigated by the fact that most of the methods are well named.  Still, when you’re not sure where you should be even looking, it can be annoying.

Appirater

Appirater is a great little library for quickly adding an alert reminding people to rate the app.   I’m not hugely convinced that a good rating boosts downloads all that much, but since this is so simple to use it’d be a shame not to add it.

InAppSettingsKit

In this version of Pint of Plain, there’s a few more settings the user can tweak.  I doubt many people ever look at the various settings you can change in the Settings App so I wanted to offer an in app alternate.  InAppSettingsKit does all the heavy lifting for you and like Appirator, so easy to include it was a no brainer.

MapKitDragAndDrop

In the old version of the app, a bar’s location was simply determined by using the GPS and only used if the accuracy was under 50m.  This was never a great solution and I wanted to give the user the option of dropping a pin the right location.  While search for how to do the drag and drop, I came across MapKitDragAndDrop which did everything I needed.

Glyphish

Not a code library but rather a set of icons, Glyphish is a great resource.  There’s an icon for nearly every tab you need and they’re all beautifully crafted.

I think the fact that there’s so many libraries and resources out there now shows how iOS has matured as a platform.  Every time I go to find out how to do something I’ve seen in another app, there’s a library for it.  It certainly makes development much easier than when I first looked at it all over 2 years ago.
