RayWenderlich.com Layout in IOS Course - Part 5

It's been a while but for god reason! I've got a promotion at work, which means I've really got my future set. However, I am not going to abandon Swift. My work over the past 20-ish months has been rewarding and to let all of that go would be a shame. True, had I not got the promotion, I would probably be gravitating towards Swift more with an aim to transition to a career in the future. Anyway, that COULD still happen but it does make me want to rethink my goals a bit. We're also on an early holiday, so plenty of time to code and do a reflective entry of where I am and where I want to be. That will happen soon! For now, let's get on with the auto layout course!

Start Time - 9:42

Intrinsic Content Size

So this is the size that will fit EXACTLY into a a view's content.

Content Hugging and Compression Resistance - these are rules that show the importance of contents not shrinking or resizing, bigger than the intrinsic size.

4 priority values to set. Vertical and horizontal for each of the above.

Content size ambiguity - when the CH and CR have the same priority. So AL does not know whether to grow or clip the size of the object.

Nesting Stack Views



So like the above!

A neat trick - command and d - duplicates an item.

Stack View Alignment and Distribution

With alignment you have left right and centre options for how the objects are aligned. Default is fill, so that the stack view is filled (for horizontal). You can also line to first or line baseline - the furthest point up or down.

So that is about alignment, makes sense.

For distribution, it's to do with spacing rather than how lined up the objects are. You can have equal spacing or equal centering.

Challenge!

Last bit for now! This is what we are going to make! Using the objects given....



So multiple stacks and options going on here. Cool!


Right we're making it from scratch! First of all we need a vertical stack view, stretched out. Then there will be views within the views...

Here's what I have! I got ALL of the objects in, then did the embedding. That worked better than starting with the stacks.




OK I was missing the top right bit - thought there was an image missing! Let's add that in.

Yep all done now



A tough challenge in the end but all good!

So this course is going well. Stack views is 100% the way to go, especially with the use of nested views! That will do for now. 

 Finish Time - 10:58 (1 hour 10 mins approx)

*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...
