cs193p – Project #1 Assignment #1 Task #2

Please note, this blog entry is from a previous course. You might want to check out the current one.

Your calculator already works with floating point numbers (e.g. if you touch 3 ↲ 4 ÷, it will properly show 0.75), however, there is no way for the user to enter a floating point number directly. Fix this by allowing legal floating point numbers to be entered (e.g. “192.168.0.1” is not a legal floating point number!). You will have to add a new “.” button to your Calculator. Don’t worry too much about precision or significant digits in this assignment.

In Storyboard change the currently blank label of the bottom left button to “.”:

cs193p – Project #1 Assignment #1 Task #1

Please note, this blog entry is from a previous course. You might want to check out the current one.

Get the Calculator working as demonstrated in lectures 1 and 2. The Autolayout portion at the end of the lecture is extra credit, but give it a try because getting good at autolayout requires experience. If you do not do autolayout, be sure to position everything so that it is visible on all iPhones (i.e. the upper left corner of the scene).

I finished this task already during the lectures, including lecture #3. For convenience sake (mostly mine) I will base the follow tasks on the code from the end of lecture #3.

The complete code for the task #1 (different branches for end of lectures #1, #2 and #3) is available on GitHub.

  • the conditional statement switch,
  • functions as types,
  • various combinations of closure syntax defining functions “on the fly”,
  • method overloading – same method name, different arguments,
  • and more Autolayout.

Like every year lecture #1 is an general introduction of the course with an overview about iOS, MVC and this time the Swift.

… and again Paul Hegarty stresses the importance of being familiar with object oriented programming as prerequisites for the course and that it is not for absolute beginners.
