In the simulator I have set up 2 keyboards (English,Greek) Within keyboardWillShow function I change the UITextView's height to be less than the existing one, as in self.page_text.frame = CGRectMake(self.page_text.frame.origin.x, self.page_text.frame.origin.y, self.page_text.frame.width, (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as NSValue).CGRectValue().origin.y - 180) The problem is that only each first time I focus on the text view the keyboard

I thought final declarations got assigned only once. Is the compiler creating an Integer object and changing what it references? 回答1: Imagine that shorthand looks a lot like this: for ( Iterator iter = listOfNumbers . iterator (); iter . hasNext (); ) { final int i = iter . next (); { System . out . println ( i ); } } 回答2: See @TravisG for an

According to the docs Proguard handles .war files, but when I try I get this: Warning: class [WEB-INF/classes/com/corp/gr/t2b/T2BChannel.class] unexpectedly contains class [com.corp.gr.t2b.T2BChannel] The docs mention something about Proguard not liking .war files with classes in the WEB-INF/classes directory. So I put all the .class files in their own .jar file in WEB-INF/lib. Then Proguard complains that it cannot find any of the JavaEE 6 classes, even though I've given it the

If the user taps the dictation button, pushes done, and then tries to dismiss the keyboard, the app crashes with: Fatal Exception: NSInternalInconsistencyException NSInternalInconsistencyException We were never set up properly to stream in this document. I was wondering if anyone knows a work around to fix this bug? I tried implementing UITextInput and leaving dictation related methods blank and

Spring MVC 解读——@RequestMapping 上一篇文章中我们了解了Spring如何处理@RequestMapping注解，并将请求映射信息保存到系统中以处理客户端发送来的请求，但是Spring是怎样接受请求，并根据请求URL来匹配正确的处理器方法呢，更重要的是Spring允许我们定义签名灵活的处理器方法，也就是说你的参数类型，顺序，返回类型都可以自定义，只要你方便就好。真的很棒，但是他怎样做到的呢？ 这篇文章我们就研究这个问题。 一、重要的类和接口 HandlerMethodArgumentResolver 一个策略接口，根据请求解析处理方法的参数值（这是重点），我们就是通过实现它来自定义我们的参数类型的。Spring默认提供了十多个类型的解析器来处理常见的方法参数，如@PathVariabe，@RequestParam， Model，@ModelAttribute等等。 HandlerMethodReturnValueHandler 一个策略接口，用来处理处理器方法的返回值(重点啊)， 我们通过实现它来自定义我们的返回类型 RequestMappingHandlerAdapter 一个HandlerAdapter的实现类，用来处理HandlerMethod，它包含了上面两个接口一系列实现类的列表，用于处理不同的参数和返回类型

The code is as follows: var newDate = new Date("2013-07-23" + " 12:00:00"); console.log(newDate.toString()); newDate = new Date(newDate.getTime() - (24 * 60 * 60 * 1000)); console.log(newDate.toString()); var date = newDate.getFullYear() + "-" + ("0" + (newDate.getMonth() + 1)).slice(-2) + "-" + ("0" + newDate.getDate()).slice(-2); console.log(date); Essentially, I am converting 2013-07-23 -> Jul 22 2013 12:00:00 GMT+1000 -> 2013-07-22 It works fine in Chrome, you can test the
