假设你的网址是 NSURL 对象名为 url ：
Assuming your url is in an NSURL object called url:
NSMutableDictionary *queryParams = [[NSMutableDictionary alloc] init];
NSArray *components = [[url query] componentsSeparatedByString:@"&"];
for (NSString *component in components) {
NSArray *pair = [component componentsSeparatedByString:@"="];
[queryParams setObject:[[pair objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding: NSMacOSRomanStringEncoding]
forKey:[pair objectAtIndex:0]];
}
...
[queryParams release];
