iOS条形码

1、NKDEAN13Barcode生成条形码。

UIImage *image = [UIImage imageFromBarcode:[[NKDEAN13Barcode alloc] initWithContent:@"6922233623211"]];

image=[UIImage imageWithCGImage:image.CGImage scale:1.0 orientation:UIImageOrientationDown];

self.imageview.image=image;

此处生成的条形码不能用POS机扫描出来，初步的推测是POS机识别不了这种编码，但手机端都能扫描出来。

2、ZXing 生成条形码，有一个zxing的objc库，用了能扫

NSError *error = nil;

ZXMultiFormatWriter *writer = [ZXMultiFormatWriter writer];

ZXBitMatrix* result = [writer encode:@"6922233623211"

format:kBarcodeFormatCode128

width:100

height:50

error:&error];

if (result) {

CGImageRef image = [[ZXImage imageWithMatrix:result] cgimage ];

NSLog(@"%@",image);

UIImage *imag=[UIImage imageWithCGImage:image];

self.imageview.image=imag;

// This CGImageRef image can be placed in a UIImage, NSImage, or written to a file.

} else {

NSString *errorMessage = [error localizedDescription];

}
