检查以下代码：

NSString *urlString = [NSString stringWithFormat:@"http://1-dot-digiphoto-01.appspot.com/v1/service/rest/getAlbums/QR/{%@}",@"123"];

NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];

[theRequest addValue: @"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest setHTTPMethod:@"GET"];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( connection )
{
    NSLog(@"Success");
}
else
{
    NSLog(@"Failed");
}

从TableView中显示NSURLConnection的服务器获取数据
