In education, in work or play, it’s always a balance of hard work and creativity. Yes, the truth is most often some place in the middle.

Participated in Subhb’s iOS dev launcher workshop today and it was really fun to chill out and mess with code with a whole bunch of like-minded people.

Stuff for my Objective C Muscle Memory

Besides the social aspect of these coding workshops, it was also a great opportunity for me to get a refresher on Objective C since I last worked on it 6 months ago.  Here’s the gist of what session #1 covered, introduced in a cute and friendly way using a “Princess” class:-

• Anatomy of an Objective C class
• Creating our own custom class
• Memory allocation when instantiating a class
• Messaging Syntax (essentially methods in an Objective C class, whether it is a class method or an instance method)
• Writing @property in a class in the header file (.h) and making them available in the implementation (.m) file with @synthesize
• And @property of course is represented by this – @property (<attributes>) <type> <name>;
• The differences between readonly, assign, copy and retain attributes in the @property declaration

Practice assignment for session #1

• replicate “SaveThePrincess” Exercise
• Add a “School” property to the princess class
• Create a new initializer method to create a princess instance with name, age and school
• Change sing method and print “Myra loves singing, she is 5 years old and she goes to Bugis Primary School”
• Change description method to print school name for debugging

And so, giving the name, age and school to my princess object, my princess Kait-lyn is 6 years old and goes to school at Phyllis Riccia.

What about your princess? :-)
