问题描述

如何将stringURL和stringSearch组合在一起？

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_]]];
}

推荐答案

Philippe举了一个很好的例子。

Philippe gave a good example.

你也可以使用普通的 stringWithFormat ：方法。

You can also use plain stringWithFormat: method.

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

这样你可以通过在字符串之间添加somethig来操作字符串，如：

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

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