使用方法：
复制 'SQLQRCodeScanner'文件夹内容到项目
1.在info.plist 在添加权限
<key>NSCameraUsageDescription</key>
<string>是否允许使用你的相机？</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>是否允许使用你的相册?</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>是否允许使用你的相册?</string>
2.import
#import "SQLQRCodeScannerController.h"
3.创建
SQLQRCodeScannerController *vc = [[SQLQRCodeScannerController alloc]init];
4.扫描返回
【1】.第一种
vc.succScanner = ^(NSString* _Nullable scanStr){
NSLog(@"scanStr:%@",scanStr);
};
vc.errScanner = ^(NSString* _Nullable errStr){
NSLog(@"errStr:%@",errStr);
};
【2】.第二种 delegate <SQLQRCodeScannerControllerDelegate>
vc.delegate = self;
- (void)qrCodeScanner:(NSString *)scanStr{
NSLog(@"delegate scanStr:%@",scanStr);
}
- (void)qrCodeFailed:(NSString *)errStr{
NSLog(@"delegate errStr:%@",errStr);
}
5.弹出ViewController
【1】.没有navigationController
vc.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:vc animated:YES completion:nil];
【2】.有navigationController
[self.navigationController pushViewController:vc animated:YES];
