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.
