Creating a custom activity indicator in Swift allows you to tailor the appearance and behavior of your loading spinner to fit the style of your app. Here's a step-by-step guide to creating a simple custom activity indicator using UIView Step 1: Create a New Swift File for the Custom Activity Indicator Create a new Swift file and name it RotatingCirclesView.swift . Add the following code to define a custom UIView subclass for your activity indicator: // // RotatingCirclesView.swift // Welcome In // // Created by Praveen Kumar on 05/09/24. // import UIKit class RotatingCirclesView : UIView { let circle1 = UIView ( frame : CGRect ( x : 20 , y : 20 , width : 60 , height : 60 )) let circle2 = UIView ( frame : CGRect ( x : 120 , y : 20 , width : 60 , height : 60 )) let position : [ CGRect ] = [ CGRect ( x : 30 , y : 20 , width : 60 , height : 60 ), CGRect ( x : 60 , y : 15 ,...
Subscripts:-
Subscripts are used to access information from a collection , sequence and a list in classes, structured and enumeration without using any sequence method.
Or
These subscript are used to store and retrieve the value with the help of index without sequence method.
Syntax:- Subscripts
subscript(<perameters>) -> <return type>{
//getter
get{
//subscript value declarations
}
set(newValue){ // setter are optional
//definition here
}
get{
//subscript value declarations
}
set(newValue){ // setter are optional
//definition here
}
Example:- Subscripts
class yearsOfMonths {
var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
var months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
subscript(index: Int) -> String{
get {
return months[index]]
}
set(newValue){
self.months[index] = newValue
}
}
}
var yom = yearsOfMonths()
print(yom[0])
//Getter
yom[0] = "December"
//Setter
print(yom[0])
Output:- January
December
