Angela Yu Xcode 2012 Course - Part 4 (lectures 44 to 50)

Four days in a row! Been consistent and regular since resolving to work through Angela's latest Xcode course.  I have 40 minutes maximum now so let's crack on!

Start Time - 15:18

Again, I'm not creating these new projects but am going to predict what to code and make a note of it here before Angela reveals the answer.

Dicee App

OK Image View takes up the entire screen - this is because Angela will have some cool green felt background to add in!

So something that's clear now is that for EVERY image there needs to be the 1x, 2x and 3x files.

Right the contents.JSON file is what is used to get all of the app icons. Neat! Assests.xcassets.

So best way seems to be to click and drag from the app icon folder to the Xcode project folder - removing what was there before.

So the image files can be dragged straight onto Xcode or into the folder as above. I'll stick to the folder way for the icons.

Top tip for images of same size - copy and paste! Much easier. Hold down alt and click and drag - will copy those items to the new area. Could be useful!

XML - complex looking code. Like HTML - doesn't need to be used or anything (yet!).



THIS is better for workability!




Right so the screenshot below shows the connected outlets. Hover/click on the circle to see what is connected to it!



Now for the button, Angela puts in UIButton instead of Any. Not sure why it is UIButton explicitly for this. Hopefully will find out another time but no issue for now.






This is the error that comes up if an outlet is not connected. Or if the name of the outlet is changed. Makes total sense and I used to get these all of the time!!



Also click on the object and see what connections it has. Click on the little cross to break the referencing outlet.

Randomisation

Cool, this has the most recent way of using the random function!

OK for the images to work TAGs are needed - each one is worth a different tag.

Randomising is easy now!



Bit about data types etc. - skimming through as this is all pretty easy.

Option to choose between manually and automatically run - could be useful.

This is a cool way of looking how data types can't just be swapped etc.



Finish Time - 15:56 (38 minutes total)

So another quick session today. Nothing particularly new learned this time, but good to see the randomisation new way in action. Some other good tips about the views and outlets too. Next time, rest of Dicee app!

*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...
