An iPhone app that allows users to view Yelp restaurants.
The following functionality is completed:
- User can view a list of restaurants in SF
- User can view the name of each restaurant
- User can view an image of each restaurant
- User can view the category of each restaurant
- User can view the rating of each restaurant
- User can view the number of reviews of each restaurant
- User can view the phone number of each restaurant
Here is a walkthrough of the implemented user stories:
It was challenging formatting the phone numbers and showing the star ratings.
For the phone numbers I extended String with a method formatPhoneNumber() throws -> String that is called on a string formatted as "+1xxxxxxxxxx" to return a string formatted as "(xxx) xxx-xxxx". It throws an error if the string is not 12 characters.
For the star ratings, I created a struct called Stars that has a dictionary imageName of image file names with the keys the numbers 0 through 5 (in increments of 0.5).
