QUESTION
Ok, bear with me. I've got a database of coordinates, I'm trying to pull that data down, decode it into a codable class that also conforms to MKPolygon and then just be able to add that polygon to a map view.
...ANSWER
Answered 2021-Feb-13 at 18:31I would not advise subclassing MKPolygon
. Frankly, I would not advise creating CustomPolygon
and Coordinate
, at all. There is no need to introduce types that mirror the native MKPolygon
and CLLocationCoordinate2D
types.
Rather than trying to make a codable MKPolygon
, I might instead suggest creating a Codable
type that just represents a collection of coordinates, which encodes an array of latitude and longitudes.
But first, let’s consider a JSON structure, an array of coordinates:
QUESTION
I am using some values to perform some calculations. For testing purposes I show in Label1 a value as string, since it is stored as a string and in Label2 I show a casted value as a Double since I need them at the end as doubles for my calculations.
The weird thing is, that when I access the ViewController the first time it doesn't show any values. But if I go back and klick on it again using the navigation controller it actually works. But I need the values right away cause my original intention is as I said, not showing some labels but rather making some calculations with it.
I made a little gif to show you what the problem is but I have problem with adding photos. Basically what happens is, that I click on the ViewController with the labels and nothing is showed. I go back and press again and the values will be showed in the labels.
Why is that and how can it be showed right away/ used for calculations right away
Thanks for the help. :)

Answered 2020-Jul-15 at 08:26You are calling UserService
's ahpPref
in your controller's viewWillAppear
. BUT you are attempting to put your valueA
(globaLajkpXc
's value) to your label in your controller's viewDidLoad
.
So what does that mean? Do you know which of these two controller's life cycle method gets called and when they do get called?
To solve your problem, have your label assigning value code
