Adding built in Google search capability to browser - ios

Question

I am trying to give my simple browser the ability to recognize that text with spaces should be treated as a google search query. To create a string that can go into a url I need to replace the spaces with "+"s.
I have attempted to do this in the first "if" statement however when I do run the program and put text with spaces into the search bar nothing happens; entering "google.com" or other urls work though.
What is wrong with my code?
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
NSString *URLString = textField.text;
NSURL *URL = [NSURL URLWithString:URLString];
if ([URLString rangeOfString:#" "].location != NSNotFound) {
NSString *plusReplace = [URLString stringByReplacingOccurrencesOfString:#" " withString:#"+"];
URL = [NSURL URLWithString:[NSString stringWithFormat:#"google.com/search?q=<%# query", plusReplace]];
}
if (!URL.scheme) {
// The user didn't type http: or https:
URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://%#", URLString]];
}
if (URL) {
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
[self.webView loadRequest:request];
}
return NO;
}

I think you might have an issue with the 3rd conditional making a 2nd request. What if you change it to this?
if (URL) {
NSString *plusReplace = [URLString stringByReplacingOccurrencesOfString:#" " withString:#"+"];
URL = [NSURL URLWithString:[NSString stringWithFormat:#"google.com/search?q=<%# query", plusReplace]];
}
if (!URL.scheme) {
// The user didn't type http: or https:
URL = [NSURL URLWithString:[NSString stringWithFormat:#"http://%#", URLString]];
}
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
[self.webView loadRequest:request];
