Treehouse Intermediate Course - Part 17 (Build Interactive Story App Project 1)

So only around 20 minutes maximum today - just a brief entry. I didn't code yesterday as the time I'd spent on the F1 sim the day before had hurt my eyes and head too much! I'm heading back to Dubai today where I have my screen, so that will make it more doable! Anyway, time to start a new project! Let's go. 

Start Time - 08:41

Intro

 I love the idea of these. As mentioned in the last blog, Angela had a fantastic one in her course before. The only issue with that was how 'messy' the code was for when the story would keep growing.

This will involve building reusable views, navigating to a new view, and going back to the beginning when done. Taking in text, delegates, complex models...will hopefully be useful!

Navigation Controllers

 Modal views.... But we are using stack views. We have a view on top of another and so on.

Navigation controller is provided by Xcode. Two jobs -

1. Present custom views from the view controller
2. Present its own custom views

There is a bar at the top of the screen - it will have a back button, label and any other options you want. You will have seen these on iOS all the time. Any views we want to present are added to the NC by means of their view controllers....

VC manages the views. NC tells the VC that we want to add/remove a VC from the stack. Starting to make more sense!

Root View Controllers

So main VC is the entry point. NC controls the ENTIRE app. We need the Root View Controller.

Embed in NC - I've seen this a few times before. This then shows the entry point is to the NC, then the arrow goes to the VC.

THE NC IS NOW THE ROOT CONTROLLER!

The NC does not contain a content view of its own. It manages a SET of VCs that display their own views.

So the root view is embedded in the NC. Going to do next two (shortish) videos then that's it for now!

Designing The Main Screen

Right pictures added from Pasan onto the assets folder.

So adding a picture after image view with constraints...all done. Link from Pasan about Image view stuff I will read up on next time -

https://developer.apple.com/design/human-interface-guidelines/ios/overview/themes/

Whizzing through this - a nice easy intro and set up!

Adding A Segue Show

We add a new VC, connect it to the button with 'show', then we have a stack view! There is an automatic 'back' button that appears to show this too.

Quiz then done for today.

Finish Time - 09:11 (30 minutes)

Well a useful intro and reminders of things on Xcode. Tomorrow I will delve deeper into the project.

*Xcode Project Entry 2* F1 Quiz - part 1

Image
It's Christmas Eve and time to code! To think, a year ago, I was plodding along with some eBook, blindly convincing myself that I was on a steady road to coding greatness. Really, it was from June where I made the decision to start again, humbling as that may seem. It would have been comforting to have completed endless 'beginner' courses but branching out and applying the theory is the key thing, which brings us to this entry. Yes, my second Xcode OWN project! I thought about doing an educational one, as there is certainly a lot of scope and relevance for that, being a teacher and all. However, making a quiz makes sense, for various reasons.  First off, I have made this before through Angela's excellent tutorial. No offence to Sandra, but hers is not even close to the elegance and effectiveness of Angela's project. The one thing to take from Sandra is the stack views. Definitely something I will use from now on. This is one of the great things about learning from...

Angela Yu Course Part 10 (up to lesson 112)

It's unlikely that I'll be able to do any Swift tomorrow as I'm going to Eastbourne today, for the weekend. So I can give half an hour now, maximum! Coding Challenge - Destini App! Choose your own adventure books! I used to ADORE these. Angela explains that these have had some sort of revival through the Lifeline games. It's very binary - yes/no mostly. I have my own experience of this based on WDC... Now the challenge is to complete the game! Having followed the first few instructions, which I found a bit confusing it must be said, I was about to surrender and see the answer. Then I managed to stop myself - I CAN do this, or at least have a good go! Even if I don't get the correct answer, it will be good practice to put what I know into practice. This is my weakness, which I keep coming back to - that when some problem solving is required, I fold far too quickly. So here is what I need to do: Let's break this down... I need to use the...

Angela Yu Xcode 12 Course - Part 7 (lectures 74 to 79)

No time to waste! Only got a short amount of time now so going to get a few minutes or so in! Start Time - 20:14 Conditionals If statement for 'love calculator' example. So a simple example for this. The idea will be that conditionals are used to show that the print statement will do it differently for whatever the number is. With updated Swift, I would use the Int.random(0...100). Easy fix that would be. Also no UIInt32 needed but just an Int. So with the if statements, it would be a STRING being returned.   Linked to the whole choose your own adventure - if/else for each choice. BMI Challenge No need to do this - easy enough to be honest. Just skimming through. BODMAS principles... So something I picked up on before is not needing the greater than AND less than value for the middle line (for the else if bmi > 18.5) A better solution, which Angela is already explaining before I could say it is returning a string instead of a Double. So the...
