QR Code scan by camera, once a result ,after that, will close the current controller

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.qrCodeNavigationTitle = @"QR Code Scanning";
[qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
   NSLog(@"strValue = %@ ", strValue);
   if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
   } else {
       UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
       [alertView show];
   }
}];

QR Code scan by camera, once a result, after that , won't close the current controller

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeContinuation];
[qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
   NSLog(@"strValue = %@ ", strValue);
   if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
   } else {
       UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
       [alertView show];
   }
}];

QR Code scan by camera , once a result , after that, will close the current controller. Its view can custom

    UIColor *white = [UIColor whiteColor];
    ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn customView:self.view navigationBarTitle:@"QR Code"];
    qrCode.VCTintColor = white; 
    [qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
        NSLog(@"strValue = %@ ", strValue);
        if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
            [alertView show];
        }
    }];

QR Code scan from the Photo Library

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.textWhenNotRecognized = @"No any QR Code texture on the picture were found!";
[qrCode recognizationByPhotoLibraryViewController:self completion:^(NSString *strValue) {
   NSLog(@"strValue = %@ ", strValue);
   [[ZRAlertController defaultAlert] alertShow:self title:@"" message:[NSString stringWithFormat:@"Result: %@", strValue] okayButton:@"Ok" completion:^{
        if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
            [alertView show];
        }
    }];
}];

QR Code scan by long-press that object, which is one of them ,UIImageView, UIButton, UIWebView, WKWebView, UIView, UIViewController

Note: Bind long-press gesture first, then using.

       Like this variable `self.imageViewExample` that 
       it needs the event of long-press. You can bind the gesture in the method `viewDidLoad()`.

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.cancelButton = @"Cancel";
qrCode.actionSheets = @[];
qrCode.extractQRCodeText = @"Extract QR Code";
NSString *savedImageText = @"Save Image";
qrCode.saveImaegText = savedImageText;
[qrCode extractQRCodeByLongPressViewController:self Object:self.imageViewExample actionSheetCompletion:^(int index, NSString * _Nonnull value) {
    if ([value isEqualToString:savedImageText]) {
       [[ZRAlertController defaultAlert] alertShow:self title:@"" message:@"Saved Image Successfully!" okayButton:@"Ok" completion:^{ }];
    }
} completion:^(NSString * _Nonnull strValue) {
    NSLog(@"strValue = %@ ", strValue);
    [[ZRAlertController defaultAlert] alertShow:self title:@"" message:[NSString stringWithFormat:@"Result: %@", strValue] okayButton:@"Ok" completion:^{
        if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
            [alertView show];
        }
    }];
}];

QR Code Scan by a custom View, There is a sample view name is ZRQRCodeScanView and use of snippet code below. There is a whole code in this project

//1.You just import this header file
#import "ZRQRCodeScanView.h"

//2.Easy to call
[[[ZRQRCodeScanView alloc] init] openQRCodeScan:self];

通过摄像头扫描二维码，扫描一次返回一个结果，并结束当前扫描控制器

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.qrCodeNavigationTitle = @"QR Code Scanning";
[qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
    NSLog(@"strValue = %@ ", strValue);
    if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
    } else {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
        [alertView show];
    }
}];

通过摄像头扫描二维码，扫描一次返回一个结果，不结束当前扫描控制器

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeContinuation];
[qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
     NSLog(@"strValue = %@ ", strValue);
     if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
          [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
     } else {
          UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
          [alertView show];
     }
}];

通过摄像头扫描，扫描一次返回一个结果，会结束挡墙控制器，并且它的view可以自定义

    UIColor *white = [UIColor whiteColor];
    ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn customView:self.view navigationBarTitle:@"QR Code"];
    qrCode.VCTintColor = white; 
    [qrCode QRCodeScanningWithViewController:self completion:^(NSString *strValue) {
        NSLog(@"strValue = %@ ", strValue);
        if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
        } else {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
            [alertView show];
        }
    }];

从手机相册中选择一张图片进行扫描，

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.textWhenNotRecognized = @"No any QR Code texture on the picture were found!";
[qrCode recognizationByPhotoLibraryViewController:self completion:^(NSString *strValue) {
    NSLog(@"strValue = %@ ", strValue);
    [[ZRAlertController defaultAlert] alertShow:self title:@"" message:[NSString stringWithFormat:@"Result: %@", strValue] okayButton:@"Ok" completion:^{
         if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
             [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
         } else {
             UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
             [alertView show];
         }
    }];
}];

通过长按要被扫描的对象，它可以是这些UIImageView, UIButton, UIWebView, WKWebView, UIView, UIViewController

注意: 先绑定长按手势，再使用。

例如这个变量，self.imageViewExample 它需要长按事件。可以在 viewDidLoad()方法中绑定该手势

ZRQRCodeViewController *qrCode = [[ZRQRCodeViewController alloc] initWithScanType:ZRQRCodeScanTypeReturn];
qrCode.cancelButton = @"Cancel";
qrCode.actionSheets = @[];
qrCode.extractQRCodeText = @"Extract QR Code";
NSString *savedImageText = @"Save Image";
qrCode.saveImaegText = savedImageText;
[qrCode extractQRCodeByLongPressViewController:self Object:self.imageViewExample actionSheetCompletion:^(int index, NSString * _Nonnull value) {
    if ([value isEqualToString:savedImageText]) {
         [[ZRAlertController defaultAlert] alertShow:self title:@"" message:@"Saved Image Successfully!" okayButton:@"Ok" completion:^{ }];
    }
} completion:^(NSString * _Nonnull strValue) {
    NSLog(@"strValue = %@ ", strValue);
    [[ZRAlertController defaultAlert] alertShow:self title:@"" message:[NSString stringWithFormat:@"Result: %@", strValue] okayButton:@"Ok" completion:^{
        if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:strValue]]){
             [[UIApplication sharedApplication] openURL:[NSURL URLWithString:strValue]];
        } else {
             UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Ooooops!" message:[NSString stringWithFormat:@"The result is %@", strValue] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
             [alertView show];
        }
    }];
}];

二维码扫描可以通过自定View， 这里有一个样例，文件名是ZRQRCodeScanView，以下是使用代码，完整的代码请试运行该项目

//1.导入头文件
#import "ZRQRCodeScanView.h"

//2.调用超简单
[[[ZRQRCodeScanView alloc] init] openQRCodeScan:self];
