objective-c - 无法创建请求:URL错误

Question

当我尝试寻找这样的位置:Florida,USA时，它就可以了，但是当我尝试这样的位置:Florida USA时，我得到了该错误:

Unable to create Request (bad url?)

问题与录音位置上的空格有关，有什么办法解决？

NSString *urlString = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=true",theLocationString];
    //Create a URL object.
    NSURL *url = [NSURL URLWithString:urlString];
    ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];

Answer 1

我认为问题在于您需要对字符串进行urlencode。空格字符不是有效的网址字符串:

NSString *urlString = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=true",theLocationString];
//Create a URL object.
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:
                    NSASCIIStringEncoding]];
ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];

如果NSASCIIStringEncoding不起作用，您可以尝试:NSUTF8StringEncoding
