在iphone中创建二维码 [英] Create QR code in iphone

问题描述

我见过一些示例代码，这些代码是从文本创建QR代码（下面是代码）。我们可以从其他数据生成QR代码（如图像）吗？

I have seen some example codes, these code are creating QR codes froms Text (below is the code).can we generate QR codes from other data also (like Image)?

 NSString *code = @"1001012023034";

Barcode *barcode = [[Barcode alloc] init];

self.view.backgroundColor = [UIColor whiteColor];

[barcode setupQRCode:code];
self.imageView.image = barcode.qRBarcode;

我的问题是，如果我们使用Image而不是字符串数据那么可能吗？

My question is if we use Image instead of string data then is it possible?

推荐答案

QR码在数据存储方面非常有限，仅限于几kb - 参见 http://en.wikipedia.org/wiki/QR_code#Storage 了解存储大小。因此，您将无法在其中放置图像。但是，你可以做的是将图像上传到某处并编码指向该图像的链接。

QR codes are pretty limited in terms of data storage, limited to a few kb - see http://en.wikipedia.org/wiki/QR_code#Storage for storage sizes. As such, you won't be able to put an image in there. What you CAN do, however, is upload the image somewhere and encode a link to that image instead.
