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];
