Enum values are used similar to a custom data type. This video makes a case for their existence and shows how to create various enum values in code.
- [Instructor] So far, we've looked…at integers, strings, and a UI label…for data types of variables.…I want to show you a different data type…that can be useful for different modes of objects.…To paint a picture here, we're going to create…a calculator in this course, and the calculator is going…to be in a few different modes.…Addition, subtraction and multiplication.…So, I'm going to create a variable…inside of viewDidLoad here and demonstrate…what I'm talking about.…
So, I create a variable called mode.…And let's say that that's going…to be an integer.…And I set it equal to zero.…And let's say that this is going…to hold whether our calculator is…in addition mode, subtraction mode,…or multiplication mode.…So, I can have an integer representing…that value right now.…So, let's say in zero, it's not in any particular mode,…and if I wanted to change it on the next line…to addition, I could change that to one.…
And then I can use code to check to see…if mode is one, and if mode's one,…then the calculator is in addition mode.…
