how to convert host of nsurl to lowercase

Question

Let's say I have www.GOOgle.com/.......

I want to change it to www.google.com/....

and keep the rest of url as it is.

I have tried with NSURLComponents, but it didn't work.

// I am taking input from textfield and making the nsurl.

 NSURLComponents *components = [NSURLComponents componentsWithString: _textfield.text]; // input from textfield
[[components host] lowercaseString];
 NSURL *urlin = [components URL]; //but this gives, www.GOOgle.com

Any lead is appreciated.

As @Larme Suggests you can use method to setHost in url

see below example

NSURLComponents *components = [NSURLComponents componentsWithString: @"https://sTackoverFlow.com/questions/47924276/how-to-convert-host-of-nsurl-to-lowercase"]; 
[components setHost:[components.host lowercaseString] ]; 
NSLog(@"%@",components.URL)

NOTE:

http:// is required to add in String otherwise you will get host nil eg https://www.sTackoverFlow.com/questions/47924276/how-to-convert-host-of-nsurl-to-lowercase it will work

If your string is only url then, you can try this,

let strURL = "http://GOogLe.Com/Testt/xyz"
let url = NSURL(string: strURL)
let domain: String = (url?.host)! //get your host name
print(domain) //GOogLe.Com

let str = strURL.replacingOccurrences(of: domain, with: domain.lowercased())
print(str) //http://google.com/Testt/xyz

1. Convert the string to lowercase.
2. Then pass the converted string value to the componentsWithString method.

Sample: NSString *lowerCaseStringValue = [_textfield.text lowercaseString]; [NSURLComponents componentsWithString: lowerCaseStringValue];
