CocoaPods 是 Objective-C 的依赖管理器，它自动简化了在项目中使用类似 ZRQRCodeViewController 的第三方库的过程。
$ gem install cocoapods需要 Cocoapods 1.0.0+ 才能构建 ZRQRCodeViewController 3.1.5。
Podfile
要将 ZRQRCodeViewController 集成到您的 Xcode 项目中使用 Cocoapods，请在此指定它：
source 'https://github.com/VictorZhang2014/ZRQRCodeViewController'
platform :ios, '7.0'
pod 'ZRQRCodeViewController', '~>3.1.5'然后，运行以下命令：
$ pod install用法
使用相机扫描 QR 码，一旦扫描出结果，将关闭当前控制器
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];
}
}];使用相机扫描 QR 码，一旦扫描出结果，不会关闭当前控制器
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];
}
}];使用相机扫描 QR 码，一旦扫描出结果，将关闭当前控制器。其视图可以自定义
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];
}
}];从相册扫描 QR 码
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];
}
}];
}];长按对象进行二维码扫描，其中的一个之一，UIImageView, UIButton, UIWebView, WKWebView, UIView, UIViewController
注意：先绑定长按手势，然后再使用。
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];
}
}];
}];通过自定义视图进行二维码扫描，其中有一个示例视图名为 ZRQRCodeScanView，下面是片段代码。在此项目中有一个完整的代码
//1.You just import this header file
#import "ZRQRCodeScanView.h"
//2.Easy to call
[[[ZRQRCodeScanView alloc] init] openQRCodeScan:self];
将二维码生成图片
//Indicate UIImageView rect
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//And then returns a UIImageView which is QRCode picture with rect through indicating data string
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com"];
在中心图标中生成二维码图片
//Indicate UIImageView rect
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//And then returns a UIImageView which is QRCode picture with rect through indicating data string and amidst a icon
UIImage *center = [UIImage imageNamed:@"centericon"];
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com" centerImage:center];
在中心图标中生成二维码图片并具有阴影效果
//Indicate UIImageView rect
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//And then returns a UIImageView which is QRCode picture with rect through indicating data string and amidst a icon and shadow effect
UIImage *center = [UIImage imageNamed:@"centericon"];
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com" centerImage:center needShadow:YES];

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，会结束遮挡控制器，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义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];
生成二维码
//指定UIImageView 的 rect 大小
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//然后，返回一个QRCode图片，通过指定大小的rect和数据字符串
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com"];
生成二维码 带 中间icon
//指定UIImageView 的 rect 大小
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//然后，返回一个QRCode图片，通过指定大小的rect和数据字符串，中间带一个icon
UIImage *center = [UIImage imageNamed:@"centericon"];
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com" centerImage:center];
生成二维码 带 中间icon ,并且带有阴影效果
//指定UIImageView 的 rect 大小
CGRect rect = CGRectMake(10, 10, [UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.width - 20);
//然后，返回一个QRCode图片，通过指定大小的rect和数据字符串，中间带一个icon, 并且有阴影效果
UIImage *center = [UIImage imageNamed:@"centericon"];
UIImageView *myImage = [[[ZRQRCodeViewController alloc] init] generateQuickResponseCodeWithFrame:rect dataString:@"https://www.baidu.com" centerImage:center needShadow:YES];
