一个字符串中的多个变量

Question

我目前有这段代码：

NSString *strURL = [NSString stringWithFormat:@"http://www.sample.com   /phpFile.php?firstname=%@",txtfirstName.text];

NSString *strURL2 = [NSString stringWithFormat:@"http://www.sample.com/phpFile.php?lastname=%@",txtlastName.text];

但问题是这会创建两个不同的行，我想要名字，姓氏和其他所有行。

所以可以这样做：

NSString *strURL = [NSString stringWithFormat:@"http://www.sample.com   /phpfile.php?firstname=%@",txtfirstName.text,txtlastName.text,txtheight.text,txtweight.text];

还是我需要做一些更复杂的事情？

提前致谢！

试试这段代码：

NSString *subStringURL = [NSString stringWithFormat:@"firstname=%@&txtlastName=%@&txtheight=%@&txtweight=%@",txtfirstName.text,txtlastName.text,txtheight.text,txtweight.text];

NSString *strURL = [NSString stringWithFormat:@"http://www.sample.com/phpfile.php?%@",subStringURL];
