Here a question for the pros... I'm developing an application on Ipad and i'm using a barcode reader with bluetooth. I have sync the barcode reader with my Ipad and I can catch the text on a textField without problems. When I read a barcode I don't want to put it on a textField, I want to catch it on a class, process it and decide what to do with it. I have searched on the internet the way to do it but I can't find it. Someone can help me? Can I do a class the delegate to receive the input strings?
我有点与它和任何帮助将失去对我非常有用的。
I'm a little lost with it and any help will be very usefull for me

推荐答案
我已经解决了创建一个隐藏文本框是成为第一个响应者创建的ViewController时的问题。之后，我也做了同样的viewController该文本字段的委托。当BT codeBAR读者做一个读他让在最后一个返回，以便它调用 - （BOOL）textFieldShouldReturn：在那里我处理这些信息。我希望这将是有用的人用同样的问题未来的危机。我张贴code：
I have solved the problem creating a hide textfield that become the first responder when the viewcontroller is created. After I have did the same viewController the delegate of this text field. When the BT codebar reader do a read he makes a return at the end so it calls the - (BOOL)textFieldShouldReturn: where I process the information. I hope that will be usefull for someone in the futur with the same problem. I post the code:
_textSender = [[的UITextField页头] initWithFrame：方法CGRectMake（150，300，300，25）;
[_textSender setBackgroundColor：[的UIColor whiteColor]];
[self.view addSubview：_textSender];
_textSender.hidden = YES;
[_textSender becomeFirstResponder]
_textSender.delegate =自我;
- （BOOL）textFieldShouldReturn：（*的UITextField）文本框{
[messageSenderProtocolDelegate消息：的TextField.text];
返回YES;
}
这不是一个beatiful办法做到这一点，这让我有点小问题，当BT吧code断开键盘出现，这就是对我不好。我希望我没有键盘观点干净所有的时间。现在，当键盘显示了$ P $，我会，如果它是一个名为功能的研究pvent他是节目
It's not a beatiful way to do it and it gives me a little problem, when the BT barcode disconnects the keyboard appears and that's not good for me. I want my view clean without keyboards all the time. Now I will research if it's a function that is called when the keyboard shows to prevent him to be show
如果有人有这将是有用的任何意见，但说感谢您的帮助埃里克！
