问题 I have a scenario where I need non-angular code (in this case Facebook and Twitter JS sdk's) to broadcast an event that angular controllers can listen to. Why? After the initial page load, I load and revise content in the page via AJAX. The content has multiple like/tweet buttons attached (like a front page of blog/aggregator). I'd like to add event hooks when a click occurs on either Facebook "Like" button or Twitter "Share" button - there are a few of those in the page, and each is changing

问题 Given a UIViewController , I would like to receive text input only from the external keyboard. Think UIKeyCommand but for any character (not just 'modified' ones). However, when I try to implement that using UIKeyInput , it seems that iOS desperately wants to display a keyboard if there is no external one connected. Is there any way to circumvent that? Specifically, to have the options to receive keystrokes from the keyboard if, and only if, one is connected? 回答1: After fiddling with a iPad

问题 I'm working with a Drupal site, and we want to set up a special URL that redirects to an external site. In other words, if http://www.mysite.com is our Drupal site, we want to have http://www.mysite.com/external redirect to the external site. I have very little experience with Drupal and have no idea how to set this up. Any help is appreciated! 回答1: If all you want is to redirect the users to the same site, when they follow a link that takes them to http://www.example.com/external, then you

问题 I'm having some trouble figuring out how to make a reference to a subroutine in an external module file. Right now, I'm doing this: External file package settingsGeneral; sub printScreen { print $_[0]; } Main use settingsGeneral; my $printScreen = settingsGeneral::printScreen; &$printScreen("test"); but this result into an error: Can't use string ("1") as a subroutine ref while "strict refs" in use 回答1: As noted in perlmodlib, you should start your module's name with an uppercase letter: Perl

问题 On Linux, is it possible to somehow disable signaling for programs externally ... that is, without modifying their source code? Context: I'm calling a C ( and also a Java ) program from within a bash script on Linux. I don't want any interruptions for my bash script, and for the other programs that the script launches (as foreground processes). While I can use a... trap '' INT ... in my bash script to disable the Ctrl C signal, this works only when the program control happens to be in the

问题 I need to run several instances of an external executable from my app. The average run time for this executable is about 3 minutes. I want to redirect output from these processes, and update a progress bar in my GUI. Of course I don't want to wait for them to return before I can continue using my app. I think I should create a thread for every instance, and update my progress bar when a thread finishes. Is this the right approach ? Also, do you recommend a good resource / documentation to
