使用方法：

復(fù)制 'SQLQRCodeScanner'文件夾內(nèi)容到項(xiàng)目

1.在info.plist 在添加權(quán)限

<key>NSCameraUsageDescription</key>

<string>是否允許使用你的相機(jī)？</string>

<key>NSPhotoLibraryAddUsageDescription</key>

<string>是否允許使用你的相冊(cè)?</string>

<key>NSPhotoLibraryUsageDescription</key>

<string>是否允許使用你的相冊(cè)?</string>

2.import

#import "SQLQRCodeScannerController.h"

3.創(chuàng)建

SQLQRCodeScannerController *vc = [[SQLQRCodeScannerController alloc]init];

4.掃描返回

【1】.第一種

vc.succScanner = ^(NSString* _Nullable scanStr){

NSLog(@"scanStr:%@",scanStr);

};

vc.errScanner = ^(NSString* _Nullable errStr){

NSLog(@"errStr:%@",errStr);

};

【2】.第二種 delegate? ? <SQLQRCodeScannerControllerDelegate>

vc.delegate = self;

- (void)qrCodeScanner:(NSString *)scanStr{

? ? NSLog(@"delegate scanStr:%@",scanStr);

}

- (void)qrCodeFailed:(NSString *)errStr{

? ? NSLog(@"delegate errStr:%@",errStr);

}

5.彈出ViewController

【1】.沒有navigationController

vc.modalPresentationStyle = UIModalPresentationFullScreen;

[self presentViewController:vc animated:YES completion:nil];

【2】.有navigationController

[self.navigationController pushViewController:vc animated:YES];
