This is a post in my series “Road to Xcode.” I am currently reading Become An Xcoder by Bert Altenburg, Alex Clarke and Philippe Mougin.

04: Printing on screen

This chapter mainly introduced me to NSLog() and using it to display results even though its main function is to display error messages. The basic idea was mainly for formatting output in a readable way by adding padding to a column of data in integer form or the use of escaping to add special characters like \n for starting a new line.

I have to remind myself that the chapter mainly talked about how to format data being outputted by the NSLog() and not actually dealing with Objective C just yet.

Well, i now theoretically know the process to printing data to the screen and next up is opening up Xcode and compiling the example program the book has been working through so far to introduce me to the basics of declaring a function, defining variables, using operators, and importing header files (I almost sound like I know what I am talking about).
