提高条码扫描iOS8的速度

Question

在iOS8中，我们会告知应识别的条形码类型，如下所示。

self.acceptedBarcodeTypes = [NSMutableArray new];
[self.acceptedBarcodeTypes addObject:@"org.iso.QRCode"];
[self.acceptedBarcodeTypes addObject:@"org.iso.PDF417"];
[self.acceptedBarcodeTypes addObject:@"org.gs1.UPC-E"];
[self.acceptedBarcodeTypes addObject:@"org.iso.Aztec"];
[self.acceptedBarcodeTypes addObject:@"org.iso.Code39"];
[self.acceptedBarcodeTypes addObject:@"org.iso.Code39Mod43"];
[self.acceptedBarcodeTypes addObject:@"org.gs1.EAN-13"];
[self.acceptedBarcodeTypes addObject:@"org.gs1.EAN-8"];
[self.acceptedBarcodeTypes addObject:@"com.intermec.Code93"];
[self.acceptedBarcodeTypes addObject:@"org.iso.Code128"];

如果我们减少类型数量，您在条形码识别方面有显着的性能提升或无关紧要？
