多个变量

Question

目前，我有这段代码：

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，这将创建两个不同行，我想的名字，姓氏，一切都在一排人。

所以才有可能做这样的事情：

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

或者我需要做更复杂的东西？

在此先感谢！

Answer 1

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

使用它，这样

Answer 2

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

Answer 3

试试这个代码：

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];

希望这有助于你。
