iphone - 使用NSURL请求时出现错误的URL

我正在尝试在iPhone 4.0 SDK中请求此类URL(对访问 token 进行了一些修改，因为您实际上不需要查看它):

https://graph.facebook.com/me?sdk=ios&sdk_version=2&access_token=123902817987|8cb9e8408d2685cef853cd80.9-747882379|UGu5NvcAHiXuGEGzkq&format=json&limit=40&until=1286619821

但是我得到了这个信息:

Failed with error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x9e657a0 {NSUnderlyingError=0x9e656a0 "bad URL", NSLocalizedDescription=bad URL}

当我在Safari或Chrome中复制并粘贴时，它可以工作。我尝试用|替换%|作为建议的here，但不起作用。

从终端询问它是这样的:

curl https://graph.facebook.com/me/statuses?sdk=ios&sdk_version=2&access_token=9999955817987|8ab9e8408d2685cef.3-747882379|UGuxWDuM&format=json&limit=40&until=1286619821

[5]+  Done                    limit=40

有任何想法吗？

最佳答案

 NSString *strURL = [loc_address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            // requesting weather for this location ...
            NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://www.google.com/ig/api?weather=%@", strURL]] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:5.0];
            [req setHTTPMethod:@"POST"];
            [req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
