NSURLConnection委托方法 [英] NSURLConnection delegate method

问题描述

我很难找到NSURLConnection委托方法实现的任何示例。

I am having a hard time to find any examples for NSURLConnection delegate method implementations.

我想通过点击按钮发送带有HTTP帖子的数据。不确定如何制作提交屏幕并提交。 （我知道如何使用微调器并将使用它们）

I want to send data with a HTTP post with a button click. Not sure how to make a "submitting" screen and "submitted". (I know how to use spinner and will use them)

我在botton点击操作下使用此代码，但无法使用任何委托内容。不知道如何使用我当前的设置来实现它们。

I am using this code under a botton click action, but unable to use any delegate stuff. Not sure how to implement them with my current set up.

NSMutableURLRequest *request = 
    [[NSMutableURLRequest alloc] initWithURL:
     [NSURL URLWithString:@"http://myURL.com"]];

    [request setHTTPMethod:@"POST"];

    NSString *postString = [wait stringByAppendingString:co];

    [request setValue:[NSString 
                       stringWithFormat:@"%d", [postString length]] 
   forHTTPHeaderField:@"Content-length"];



    [request setHTTPBody:[postString 
                          dataUsingEncoding:NSUTF8StringEncoding]];

    //[[NSURLConnection alloc] initWithRequest:request delegate:self];
    [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];


    [SVProgressHUD dismissWithSuccess:@"Submission Successful"];

推荐答案

您需要使用新的NSURLConnectionDataDelegate协议。

You need to use the new NSURLConnectionDataDelegate protocol.

我在这里找到了一些例子：
