iOS 識別相冊中的二維碼或條形碼

前言: 使用CIDetector這個類只能識別二維碼圖片,條形碼目前暫不支持

能夠經過使用ZBarSDK第三方來識別相冊中的二維碼或條形碼

第一步: 導入SDK

pod 'ZBarSDK', '~> 1.3.1'
複製代碼

第二步:

//打開相冊
- (void)openPhoto {
   //ZBarsSDK初始化
   ZBarReaderController *imagePicker = ZBarReaderController.new;
   imagePicker.showsHelpOnFail = NO;//禁止顯示讀取失敗頁面
   imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
   imagePicker.delegate = self;
   imagePicker.allowsEditing = YES;
   [self presentViewController:imagePicker animated:YES completion:nil];
}

//選中圖片後的處理
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<UIImagePickerControllerInfoKey, id> *)info {
   
   id<NSFastEnumeration> results = [info objectForKey:ZBarReaderControllerResults];

   ZBarSymbol *symbol = nil;

   for (symbol in results) {
       break;
   }
   
   [picker dismissViewControllerAnimated:YES completion:^{
       //掃碼信息
       NSString *QRCodeString = symbol.data;
       NSLog(@"QRCodeString = %@",QRCodeString);
   }];
}

備註:若是想經過ZBarSDK來進行拍照識別二維碼和條形碼也能夠,只需將 - (void)openPhoto;中的sourceType改成:
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
便可, 可是注意:這種方式是拍照識別,不是掃一掃識別;
