objective-c - NSURL接続が認識されません

Question

を認識しようとすると、問題が発生しNSURLConnectionます。ある間は単純imgConnectionに認識されませんxmlConnection。

- (void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {

    if (connection == xmlConnection) {
        [dataFinale appendData:data];
        NSLog(@"XML");
    }
    else if (connection == imgConnection){
        [imgData appendData:data];
        NSLog(@"IMG");
    }

}

NSURLRequest *requestImg = [NSURLRequest requestWithURL:urlImg cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];

imgConnection = [NSURLConnection connectionWithRequest:requestImg delegate:self];
