一个简单的二维码和条码扫描器，有一套自定义的扫描动画以及界面，支持相机缩放，还可以生成和识别二维码。(A simple QR code and barcode scanner, which has a set of custom scanning animation and interface, supports camera zooming, and can generate and identify QR code.)
Using CocoaPods:
pod 'DYFCodeScanner', '~> 1.2.1'
Or
# Install lastest version.
pod 'DYFCodeScanner'

- 导入头文件 (Import Header)
#import "DYFCodeScan.h"
- 扫描二维码/条形码 (Scanning QRcode / Barcode)
- 支持push和模态两种场景过渡。 (Supporting push or modal transition.)
- 根据项目的需求，选择之一即可。(According to the needs of the project, you can choose one of them.)
- 当你要推进视图控制器，你可以选择隐藏或者不隐藏导航条。(When you want to push the view controller, you can choose to or not to hide the navigation bar.)
- (IBAction)scan:(id)sender {
static BOOL shouldPush = YES;
static BOOL naviBarHidden = YES;
DYFCodeScanViewController *codesVC = [[DYFCodeScanViewController alloc] init];
codesVC.scanType = DYFCodeScanTypeAll;
codesVC.navigationTitle = @"二维码/条形码";
codesVC.tipString = [NSString stringWithFormat:@"将二维码/条形码放入框内，即自动扫描"];
codesVC.resultHandler = ^(BOOL result, NSString *stringValue) {
if (result) {
[self showResult:stringValue];
} else {
NSLog(@"QRCode Message: %@", stringValue);
}
};
if (shouldPush) {
codesVC.navigationBarHidden = naviBarHidden = !naviBarHidden;
[self.navigationController pushViewController:codesVC animated:YES];
} else {
[self presentViewController:codesVC animated:YES completion:NULL];
}
shouldPush = !shouldPush;
}
- (void)showResult:(NSString *)value {
if (self.m_textView.text.length > 0) {
self.m_textView.text = @"";
}
self.m_textView.text = value;
}
- 生成二维码 (Generating QR code)
- 生成带中心图像的二维码 (Generating QR code that contains center image)
- (IBAction)generateQRCode:(id)sender {
CGRect rect = self.qrc_imageView.frame;
DYFQRCodeImageView *imageView = [DYFQRCodeImageView createWithFrame:rect stringValue:@"http://img.shields.io/cocoapods/v/DYFAssistiveTouchView.svg?style=flat" centerImage:[UIImage imageNamed:@"cat49334.jpg"]];
self.qrc_imageView.image = imageView.image;
}
- 生成带颜色的二维码 (Generating QR code that contains backgroudColor and foregroudColor)
- (IBAction)generateColorQRCode:(id)sender {
CGRect rect = self.cqrc_imageView.frame;
DYFQRCodeImageView *imageView = [DYFQRCodeImageView createWithFrame:rect stringValue:@"http://img.shields.io/cocoapods/p/DYFAssistiveTouchView.svg?style=flat" backgroudColor:[UIColor grayColor] foregroudColor:[UIColor greenColor]];
self.cqrc_imageView.image = imageView.image;
}
- 生成带中心图像颜色的二维码 (Generating QR code that contains center image, backgroudColor and foregroudColor)
DYFQRCodeImageView *imageView = [DYFQRCodeImageView createWithFrame:CGRectMake(30, 88, 200, 200) stringValue:@"https://github.com/chenxing640/DYFAuthIDAndGestureLock" backgroudColor:[UIColor grayColor] foregroudColor:[UIColor greenColor] centerImage:[UIImage imageNamed:@"cat49334.jpg"]];
[self.view addSubview:imageView];
- 识别二维码 (Recognizing QR code)
- (void)recognizeQRCode:(UILongPressGestureRecognizer *)recognizer {
UIImage *qrcodeImage = ((DYFQRCodeImageView *)recognizer.view).image;
NSString *stringValue = [qrcodeImage yf_stringValue];
#if DEBUG
NSLog(@"stringValue: %@", stringValue);
#endif
