Simple QRCode detector and generator in Swift
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 SwiftQRCode
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 iconView.image = QRCode.generateImage("Hello SwiftQRCode", avatarImage: UIImage(named: "avatar"), avatarScale: 0.3)
头文件格式是 "项目名称-Swift.h"
#import "QRCodeDemoObjc-Swift.h"
@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 [QRCode generateImage:@"Hello SwiftQRCode" avatarImage:[UIImage imageNamed:@"avatar.jpg"] avatarScale:0.25];
