Question

我不知道如何从connectionDidFinishLoading获得结果。我有这些代码：

connect.m：

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];

    NSString *result = [[NSString alloc] initWithBytes:[self.dataResponse bytes] length:[self.dataResponse length] encoding:NSUTF8StringEncoding];
}

videos.m：

@property (nonatomic, retain) Connect *connect;

- (void)viewDidLoad
{
    self.connect = [[Connect alloc] initWithDelegate:self
                                       onSuccess:@selector(responseSuccess:)
                                         onError:@selector(responseError:)];
}

我想知道我是怎么得到的，在videos.m中是来自connect.m的结果

connectionDidFinishLoading告诉你完成了。您需要实施协议NSURLConnectionDataDelegate并使用connection:didReceiveData:来收集数据。

请注意，您的数据会以多个块的形式出现，因此connection:didReceiveData:会被多次调用，您必须继续将新的数据块追加到最后才能调用connectionDidFinishLoading。< / p>
