UIActivityViewIndicator in browser while loading and if string contains http:// remove it

Question

I'm creating a simple web browser as an exercise.

-(IBAction)go:(id)sender {
NSString *query = [_urlField.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@",query]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
}

I would like it to know how I could add a UIActivityIndicator while loading my webView.

2nd question:

Is it possible to remove the http:// if the user enters it? I know you can do this in PHP like this:

if(strpos($URL, "http://") !== false)

How could I use it in Objective C?

Thanks you all for helping me.

Please in the future, separate your questions. – IluTov Nov 17 '12 at 18:26 — IluTov, Nov 17 '12 at 18:26

For the first questions, check out this post.

And the second:

NSString* urlWithoutProtocol = [urlWithProtocol stringByReplacingOccurrencesOfString:@"http://" withString:@""];

Thanks @NSAddict. But what if I want to add various NSStrings to replace items.. I needed to remove my first line of code to get it working and get urlWithProtocol into urlField.text. I also edited NSString *query – Thiebout Nov 17 '12 at 18:37
What do you mean? Can you make an example? – IluTov Nov 17 '12 at 18:39
I used this code NSString *query = [_urlField.text stringByReplacingOccurrencesOfString:@"http://" withString:@""]; But now I want also to remove @"www." into @"" – Thiebout Nov 17 '12 at 18:40
Then just do [urlWithProtocol stringByReplacingOccurrencesOfString:@"www." withString:@""] again – IluTov Nov 17 '12 at 18:41
But what should I place before that line of code? I cant use NSString *query again.. – Thiebout Nov 17 '12 at 18:43
of course you can :) query = [query stringByReplacingOccurrencesOfString:@"www." withString:@""]; – IluTov Nov 17 '12 at 18:49
you must not define the query variable again – IluTov Nov 17 '12 at 18:49
"NSString *query" says to the compiler to make a variable which should hold a NSString object reference. If you have defined it once in a certain scope, you can never define it again. Then you can just use it's name to get or set it. – IluTov Nov 17 '12 at 18:53

haha, it's not going to be enough. Voted you up though. thanks – IluTov Nov 17 '12 at 19:35
NSString *query = [urlWithProtocol stringByReplacingOccurrencesOfString:@"http://www." withString:@""]; query = [urlWithProtocol stringByReplacingOccurrencesOfString:@"http://" withString:@""]; – IluTov Nov 17 '12 at 19:37
Because there might be other parts of the url with "www." Like http://www.ilijatovilo.ch/?redirect=www.someotherwebsite.com – IluTov Nov 17 '12 at 19:38
