Most of the examples I see for UIActionSheet (the iOS pop-up menu) show static choices and checking for which one was picked by using constant values. That’s not going to work if your menu needs to be dynamic. For example, if you want to have an option to Email or Print an item, you might [...]
I was having a problem recently with a UITableView, where the swipe-to-delete gesture wasn’t working. The documentation is pretty clear that your table will get the swipe to delete behaviour if you implement the tableView:commitEditingStyle:forRowAtIndexPath: method in your UITableViewDataSource delegate. So, in other words, implementing this one method in your data source should be enough [...]
I like writing software to scratch a personal itch, and answering the “what’s for dinner” question has always been something I figured computers could help with. I had a PlayBook, development tools, and a desire for an app that would make it easy to quickly put together a plan for the meals for the week. [...]
I posted my AIR-based SmugMug Uploader about a year ago, and back then, I had rolled my own version of a SmugMug API client. Then I found the as3smugmuglib project on Google Code. I changed the app to work with that API instead of my own code. Because I used Cairngorm when I built the [...]
Bandwidth is both expensive and cheap. It’s cheap at a lot of hosts and for a lot of consumers, because providers expect we’re not going to use what we’re allocated, and yet expensive when purchased in bulk, where the assumption must be that it will all be used. Every time I hear about how expensive [...]
There’s a service called Disqus that provides hosted commenting for your blog or website. My Ottawa Events site was recently hit by a deluge of spam – so much so that I had to disable commenting completely. I discovered Discus through Dave Winer’s blog, and it seems like it’s worth a shot, so I’ve enabled [...]
Joel posted a short article: Don’t Hide or Disable Menu Items. I think it’s bad advice. Consider Paste or Undo. If you click the Edit menu, you can tell from the enabled state of the Paste item whether or not there’s something on the clipboard that can be pasted. Same with Undo. If Save is [...]
I just submitted a little job to RentACoder (converting an ASP.NET site to PHP for easier hosting – I’m not much of a PHP developer) and part of their new wizard has a bit about estimates. You can supply a deadline, or you can ask the bidders to estimate how long the job will take, [...]
Here’s a blog post by Jim Springfield at Microsoft about IntelliSense in Visual Studio 10. I like to hear that IntelliSense is going to be fixed, but I’ve been hearing that for many versions of Visual Studio now, and I have a hard time believing it. IntelliSense for C++ code has always been unreliable in [...]
I just finished reading Steve Krug’s book Don’t Make Me Think!: A Common Sense Approach to Web Usability on Safari. The first edition was written in 2000, but it’s amazing how much of it still applies. And not just to web usability. The book is about web design, and how to create sites that users [...]
