MZCode

二维码、条形码扫描及生成

@property (nonatomic, strong) MZCodeScanView *scanView;
@property (nonatomic, strong) MZCodeScanTool *scanTool;

构建扫描样式视图

self.scanView = [[MZCodeScanView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
self.scanView.backgroundColor = UIColor.clearColor;
self.scanView.scanRect = CGRectMake(40, 180, (self.view.frame.size.width - 2 * 40), (self.view.frame.size.width - 2 * 40));
self.scanView.angleColor = [UIColor blueColor];
self.scanView.isShowBorder = NO;
self.scanView.borderColor = [UIColor whiteColor];
self.scanView.notRecoginitonAreaColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
self.scanView.animationImage = [UIImage imageNamed:@"MZCode.bundle/scanLine"];
self.scanView.isShowMyCode = YES;
self.scanView.tipDescription = @"将二维码放于框内\n即可自动扫描";
[self.view addSubview:self.scanView];
__weak typeof(self) weakSelf = self;
self.scanView.codeScanBlock = ^{
	MZQRCodeViewController *qrCodeVC = [[MZQRCodeViewController alloc] init];
	qrCodeVC.modalPresentationStyle = UIModalPresentationFullScreen;
	[weakSelf.navigationController presentViewController:qrCodeVC animated:YES completion:nil];
};
self.scanView.flashSwitchBlock = ^(BOOL open) {
	NSLog(@"open:%d", open);
};
self.scanTool = [[MZCodeScanTool alloc] initWithPreview:preview 		andScanFrame:self.scanView.scanRect];
self.scanTool.scanFinishedBlock = ^(NSString *scanString) {
	NSLog(@"扫描结果 %@", scanString);
	[weakSelf.scanTool sessionStopRunning];
};
self.scanTool.monitorLightBlock = ^(float brightness) {
    NSLog(@"当前亮度 %lf", brightness);
	if (brightness < -2.0) {
    	// 环境太暗,显示闪光灯开关按钮
    	[weakSelf.scanView showFlashSwitch:YES];
	} else if (brightness > 0) {
    	// 环境亮度可以,且闪光灯处于关闭状态时,隐藏闪光灯开关按钮
    	if (weakSelf.scanView.flashOpen) {
        	[weakSelf.scanView showFlashSwitch:YES];
    	} else {
        	[weakSelf.scanView showFlashSwitch:NO];
    	}
	}
};
[self.scanTool sessionStartRunning];
[self.scanView startScanAnimation];

一句话生成二维码

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(30, 20, CGRectGetWidth(bgView.frame) - 60, 300)];
NSString *codeString = @"这是一个测试用的二维码";
NSInteger type = 2;
if (type == 1) {
  // 方式一
  	imageView.image = [MZCodeScanTool createQRCodeImageWithString:codeString size:CGSizeMake(CGRectGetWidth(bgView.frame) - 60, 300)];
} else {
  // 方式二
  	imageView.image = [MZCodeScanTool createQRCodeImageWithString:codeString size:CGSizeMake(CGRectGetWidth(bgView.frame) - 60, 300) frontColor:[UIColor orangeColor] backColor:[UIColor whiteColor] centerImage:[UIImage imageNamed:@"MZCode.bundle/scanFlashlight"]];
}

一句话生成条形码

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(30, 20, CGRectGetWidth(bgView.frame) - 60, 60)];
NSString *testBarString = @"string_date_20201210_time_1200";
imageView.image = [MZCodeScanTool createBarCodeImageWithString:testBarString 	size:CGSizeMake(CGRectGetWidth(bgView.frame) - 60, 60)];
