如何获得IOS的响应体？

Question

现在我想得到回复正文。我是IOS开发人员中的新人。我只知道我可以使用response.statusCode来获取httpstatuscode，例如400,500等等。但如何获得反应机构。也许allheaderFileds或数据或error.Description？

有关详细信息，请访问：URL Loading System Programming Guide

您需要一个作为NSURLConnection代表的对象。你需要有一个receivedData成员变量，你需要实现委托方法：

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    [receivedData setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    // Append the new data to receivedData.
    // receivedData is an instance variable declared elsewhere.
    [receivedData appendData:data];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    // do something with the data

    // release the connection, and the data object
    [connection release];
    [receivedData release];
}
