How to combine two strings in Objective-C for an iPhone app

Question

How can I combine "stringURL" and "stringSearch" together?

- (IBAction)search:(id)sender;{
stringURL = @"http://www.websitehere.com/index.php?s=";
stringSearch = search.text;
/* Something such as:
 stringURL_ = stringURL + stringSearch */
[web loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:stringURL_]]];
}

Answer 1

NSString* combinedString = [stringUrl stringByAppendingString: search.text];

Answer 2

Philippe gave a good example.

You can also use plain stringWithFormat: method.

NSString *combined = [NSString stringWithFormat:@"%@%@", stringURL, stringSearch];

This way you can manipulate string even more by putting somethig inbetween the strings like:

NSString *combined = [NSString stringWithFormat:@"%@/someMethod.php?%@", stringURL, stringSearch];

Answer 3

NSString * combined = [stringURL stringByAppendingString:stringSearch];

Answer 4

Instead of stringByAppendingString:, you could also use

NSString *combined = [NSString stringWithFormat: @"%@%@", 
                                 stringURL, stringSearch];

This is especially interesting/convenient if you have more than one string to append. Otherwise, the stringbyAppendingString: method is probably the better choice.
