'text' 可能会被弃用,因为ZXingWidgetController.m中的接收器类型未知
[self presentResultForString:[twoDResult text]];
请帮忙
[self presentResultPoints:[twoDResult points] forImage:image usingSubset:subset];
[self performSelector:@selector(alertDelegate:) withObject:[[twoDResult text] copy] afterDelay:0.0];
decoder.delegate = nil;
