Concept iPhone Application

9 years ago, mid-November | 3 Comments

I’ve been messing about trying to learn how to write iPhone apps. There’s a lot to take in but at the moment I’ve managed a concept application. A little shop (of horrors ;). At the moment it simply reads data from an sqlite database and then displays information on the product. The buy now button currently just jumps to the product url at Linitx.com.

Update: Added a screenshot when rotated. The iPhone SDK handles the rotation automatically, all you need to do is specify which parts of which objects move or resize. All that can be done from Interface Builder. Easy as pie. Also note the changed title bar colour, in keeping with LinITX, and the title text. The shop title (LinITX) and shop base product URL are read from a plist file. I suppose they could be read from the sqlite db but I am experimenting so learning how to read a plist file is useful too.

Update 2: Spent ages last night trying to work out why some of the text descriptions for products came out of the database as null. Discovered that when importing the data file it wasn’t using UTF8 encoding, which is apparently all sqlite deals with. Loading up the source data file into TextEdit under OSX and saving it as UTF8 then reimporting solved the problem. I also modified how things are displayed. The image and text are inserted into a UIWebView so are now scaleable by the user. The images are also base64 encoded and in the database. This increases the database size but means the application can still be used offline. Before none of the pictures would display if there was no network connectivity.

Update 3: Added the ability to search the list. The search bar appears when the search button is pressed and hides again when the search is complete.

Time Management, tips from a pro.

9 years ago, mid-August | 2 Comments

Last night I decided to take a look at Randy Pausch’s Time Management video and rather than ending up trying to gnaw off my own head I found it quite interesting. When you find out that this man is actually dying and has something like four months left it does bring things into better perspective.
