Getting a value from url by using components separated by string - ios

Question

I have a url that looks like this :
https://google.com/image/ghwUT23Y.jpeg
I want to be able to achieve something like this:
section = image;
value = ghwUT23Y;
I have tried to explode the url and usecomponentsSeperatedByStringmethod to grab the values I need.
if ([[explodedUrl firstObject] containsString:#"google.com"] && ![[explodedUrl firstObject] isEqualToString:#"https://google.com/"]) {
NSString *sectionString = [[[explodedUrl lastObject] componentsSeparatedByString:#"/"] firstObject];
NSLog(#"redirectttttt: %#",sectionString);
NSString *itemString = [[[explodedUrl lastObject] componentsSeparatedByString:#"/"] lastObject];
NSLog(#"redirectttttt:2 %#",itemString);
Problem:
Using this method, itemString returns me the value : ghwUT23Y.jpegbut sectionString returns me https://
How would I be able to get image as a section?

Answer 1

You need to convert your string to url first and use the pathComponents method to access each components of that url.
Objective C:
NSURL *url = [NSURL URLWithString:#"ttps://google.com/image/ghwUT23Y.jpeg"];
NSMutableArray *components = [[url pathComponents] mutableCopy];
NSString *fileName = [components lastObject];
[components removeLastObject];
NSString *section = [components lastObject];
NSLog(#"File : %#, Section: %#",fileName, section);
Swift
let url = URL(string: "https://google.com/image/ghwUT23Y.jpeg")
var components = url?.pathComponents
let fileName = components?.popLast()
let section = components?.popLast()

Swift :
func detectUrl() {
let strLongDescription = "https://google.com/image/ghwUT23Y.jpeg"
if(strLongDescription.contains("image")){
var arrString : [String] = strLongDescription.components(separatedBy: "google.com/")
let lastOfarrString : String = arrString.last!
arrString = lastOfarrString.components(separatedBy: "/")
let section = arrString.first!
let value = arrString.last!
}
}
