[Intro to IOS] Prework - Review my Tip Smart app

[vnu]

Hi @timothy1ee and @nesquena. I've completed the iOS pre work tip calculator app.

Due to some of my design choices, I've implemented the optional work little different than some of the example apps.

Can you please review? cc/ @codepathreview

Excellent work Vinu! Great to see you tackle a bunch of optionals and come up with a unique design for your app! As a CodePath alum, some of the following info might not be new to you, but I'll include it just so you have all the info.

This pre-work is a preview of our weekly project process. Generally, weekly projects take between 5-10 hours to complete the required features and an additional 5-10 hours to complete the optional features. In general, we've seen that the more hours you log, the quicker you improve your proficiency with iOS.

The purpose of this project was to begin to explore Xcode and to get a broad overview of iOS development using Swift. For example, in this project, we explored the following concepts:

• Code styling in Swift. You can find some code styling guides here:
  • Ray Wenderlich Swift Style Guide
  • Github Swift Style Guide
• Views are created in Storyboard, Interface Builder, or programmatically, but they have the same goal: instantiate, initialize, and layout view objects. We use IBOutlets to give names to view objects, similar to giving unique ids to divs in HTML.
• We registered for touch events, which can be done programmatically or via IBActions.
• We explored NSUserDefaults, one of the four persistence strategies in iOS.
• View controllers have a set of methods that are called when it loads, appears, or disappears. These are called view controller lifecycle methods.
• Do your views look good on iPhone 4, 5, and 6? We will cover in class how to use Auto Layout to robustly design your views for different screen sizes and OS versions.
• After this assignment, you should understand the purpose of IBOutlets and IBActions as well as the basics of designing views and programmatically interacting with the views from the controller.

The next step is a brief phone conversation with the teaching team here which we'll be scheduling as it gets closer to the start of the bootcamp.

During the phone call, we'll ask you a few simple language questions that may include things like: strong vs weak properties, optionals, blocks/closures, and categories/extensions. We'll also ask you about why you want to learn iOS and what apps you're interested in building.

Feel free to continue making improvements to the app before we schedule the phone call. We'll check it one more time right before the call. We give priority to people that demonstrate that they are willing to put a lot of time into this class.

@nickai Thanks for the feedback. Can you give me more updates about the timeline ? As roughly when will the call be and when will I know the results etc., cc/ @codepathreview

[nickai]

@vnu - We'll be starting the phone calls in early to mid January and you'll know the results shortly after the call.

Have a nice holiday!

Thanks @nickai. Happy holidays to you too :)

I worked on another branch called auto-layout that has the auto layout set and uses size classes. Both the branches will not work in landscape mode. They work only with portrait mode. I tested it through emulator and have been using my app on my iPhone 6 plus for all my tip Calculations :) Nothing can beat the happiness than using your own app to do something!!! 😀😎 cc/ @codepathreview
