iOS中 第三方LBXScan庫二維碼掃描
阿新 • • 發佈：2019-02-13
實現功能的話就是常見的二維碼、條形碼的掃描識別。該庫都已將完全封裝好了，可以直接使用。當然了也可以自己定製樣式的。
1、首先需要
cocoaPods匯入pod ‘LBXScan’, ‘~> 1.1.1’
在此不做過多介紹，如有需要手動匯入，可自行上網搜尋下載，將JQScan資料夾直接拖到你的工程中即可。
2、介面效果如下,可以掃描相簿二維碼,開啟閃光燈,生成二維碼。
3、介面和功能都集中在SubLBXScanViewController.m中，如需修改可直接修改。
二維碼的生成在MyQRViewController.m
4、我在我工程首頁的導航欄添加了掃描按鈕
//掃描按鈕
UIButton *scannerBtn = [UIButton buttonWithType:UIButtonTypeCustom]; 實現相應方法，更改掃描介面的佈局樣式
-(void)scanner:(id)sender
{
//設定掃碼區域引數設定
//建立引數物件
LBXScanViewStyle *style = [[LBXScanViewStyle alloc]init];
//矩形區域中心上移，預設中心點為螢幕中心點
style.centerUpOffset 其中最後的這個方法就是在父類中寫的push推出，再次我就不再更改。
[self bPushViewController:vc animated:YES];
}父類方法如下：
#pragma mark - 自定義導航push和pop
- (void)bPushViewController:(UIViewController *)viewController animated:(BOOL)animated {
[self.navigationController pushViewController:viewController animated:animated];
}5、掃描顯示頁面的定製
