SwiftQRCode

Simple QRCode detector and generator in Swift

• QRCode detector
• QRCode generate

• iOS 8.0+
• Xcode 7.0

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

To integrate SwiftQRCode into your Xcode project using CocoaPods, specify it in your Podfile:

platform :ios, '8.0'
use_frameworks!

pod 'SwiftQRCode'

Then, run the following command:

$ pod install

You should open the {Project}.xcworkspace instead of the {Project}.xcodeproj after you installed anything from CocoaPods.

For more information about how to use CocoaPods, I suggest this tutorial.

• import framework

import SwiftQRCode

• scan qrcode

let scanner = QRCode()

override func viewDidLoad() {
    super.viewDidLoad()

    scanner.prepareScan(view) { (stringValue) -> () in
        println(stringValue)
    }
    scanner.scanFrame = view.bounds
}

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    // start scan
    scanner.startScan()
}

• generate qrcode image

// generate qrcode
iconView.image = QRCode.generateImage("Hello SwiftQRCode", avatarImage: UIImage(named: "avatar"), avatarScale: 0.3)

• import "ProjectName-Swift.h"

头文件格式是 "项目名称-Swift.h"

#import "QRCodeDemoObjc-Swift.h"

• scan qrcode

@property (nonatomic, strong) QRCode *scanner;

- (void)viewDidLoad {
    [super viewDidLoad];

    // alloc and prepare for scan
    self.scanner = [[QRCode alloc] init];
    [self.scanner prepareScan:self.view completion:^(NSString * __nonnull stringValue) {
        NSLog(@"%@", stringValue);
    }];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    // start scan
    [self.scanner startScan];
}

• generate qrcode image

// generate qrcode
[QRCode generateImage:@"Hello SwiftQRCode" avatarImage:[UIImage imageNamed:@"avatar.jpg"] avatarScale:0.25];
