ios-NSURL字符串如何批量传递参数

Question

创建了一个应用，需要在nsurl同时传递多个参数。

代码：

responseData = [[NSMutableData data] retain];
ArrData = [NSMutableArray array];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://rate-exchange.appspot.com/currency?from=%@&to=%@&q=%@",strfrom,strto,strgo]];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
//NSURLRequest *request1 = [NSURLRequest requestWithURL:
//[NSURL URLWithString:@"http://rate-exchange.appspot.com/currency?from=%@&to=%@&q=1",strfrom,strto]];

不知道这段代码能实现么？需要什么地方改进么？多谢您的指点。

Answer 1

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://rate-exchange.appspot.com/currency?from=%@&to=%@&q=%@",strfrom,strto,strgo]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

这样就ok了。
