In a previous post I explained the facts that forced us to re-think our project idea. Basically, our cool idea of an iPhone tied to a skateboard to create a exertion game require too much programming time. So we searched another idea who is required to be simpler and easy to be implemented in the remaining time. So we got us a round table (the ones in BIT cafeteria are the best!) and put our minds to work. First step : Use the Initial Design Techniques – Brainstorming (as learned in DIS I) Our goal: collect as many ideas of […]

In the last meeting, our tutors, Mr. Heller and Mr. Karrer, shared with us some of their experience using the sensors which made us reconsider the project idea. The ideaBecause of the new introduction in iPhone programming and the rich set of sensors of this device, our project envisioned an iPhone attached to the board in order to track the skateboard movements. The data pulled out by the iPhone is the initial acceleration (the one when the user starts riding with the board), and lateral or up-down acceleration when he does turns or jumps with the board. First, the iPhone […]
While setting up the Maven for Eclipse, if you use a Java JRE instead of JDK you’ll be prompted like this: Clicking on the first active text takes you to their Help website – Running Eclipse section where you’ll find a plethora of attributes to set in order to customize your IDE.
Almost any time you’ll need to pull some data from the web. Using Objective-C you have at your disposal a pretty good XML parser – the event-based version. What really means is that instead of building in-memory tree with the structure of the XML you’ll have some events raised when the parser encounters a special token – the most usual ones are tag start, tag end and found comments. The parsing goes node by node and is not nesting-sensitive. As soon as the parser returns you a node, you don’t know where in the structure you are currently anymore. As […]
While reading the book by Mr. Kochan (1st ed): "Programming in Objective C" , I noticed that he uses the following code (you can see it at pages 342-344) to explain that the initWithString is preferable to stringWithString because the AddressCard class would own the name variable contents. Also, I don’t get any errors making repeated calls to the setName version with the stringWithString method. //I didn't added here the header file which has the needed declarations #import "AddressCard.h" @implementation AddressCard; -(NSString *) name{ return name; } //Recommended code: -(void) setName: (NSString *) theName{ [name release] name = [[NSString […]
