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? :-)
