messages

I'm trying to implement a simple Inbox system for users of my app so that can send basic messages to each other - just like in many forum systems. If User has_many :messages , how do I keep track of and notify the User of messages unread since last time they were read? I'm thinking clicks on the link to the Messages screen need to be recorded in a separate table ( MessagesClicks ). Is that the best approach here? So then I check the MessagesClicks table to see if any new messages have arrived since the last time that link was clicked - based on a last_clicked or updated_at field . I would keep

When I create a new project using the "Messages Application" template of Xcode 8 and try to run it on iOS simulator, I get the following error: Title The request to open com.myDomain.MyApp failed. Details The request was denied by service delegate ( SBMainWorkspace ) for reason: NotFound ("Application "com.myDomain.MyApp" is unknown to FrontBoard"). The message is the same for Objective-C and Swift projects. I don't find any search result for this message yet, so any hint will be helpful. I will update the question as I progress. Edit This error occurred with Xcode 8 beta versions. You may

I need to get the resolved error messages programmatically in the controller. The default validation message for typeMismatch errors are not populating from my messages.properties file. I have a form backing object where a field is an Integer. If I submit a string for that field I get: Failed to convert property value of type 'java.lang.String' to required type 'java.lang.Integer' for property 'establishedYear'; nested exception is java.lang.NumberFormatException: For input string: "1995a" as the default message in the ObjectError. Here's my controller that output it: @RequestMapping(method =

So the chain of events is: The user submits a form. During the processing of the submission, there is a message generated, such as "Your record was saved." The user is redirected to a new page, say the search results. The new page needs to display the message. So, the question is how to get the message from step 2 to step 3? This is only one simple example...there are many other much more complicated examples. I am using PHP. Needs: supports multiple messages and need to be formatted on the receiving machine as required messages can be added on the same page (such as within step 4) messages

How do I pass along an event between classes? I know that sounds ridiculous (and it is) but I've been stumped on this for the past little while. Search didn't turn up a similar question so I figured I would pose it. Here are the objects involved: WinForm -> Speaker -> Tweeter -> Woofer [Speaker, Tweeter, Woofer] all declare a "SpeakToMe" event that sends a simple string message. The events are declared using the standard pattern: public delegate void SpeakToMeHandler(object sender, SpeakToMeEventArgs e); public event SpeakToMeHandler SpeakToMe; protected virtual void OnSpeakToMe(string message

I know that javascript, for example supports functions inside of functions, like so: function doSomething(){ function doAnothingThing(){ //this function is redefined every time doSomething() is called and only exists inside doSomething() } //you can also stick it inside of conditions if(yes){ function doSomethingElse(){ //this function only exists if yes is true } } } Does objective-c support this? Theoretical example: -(void) doSomething:(id) sender{ -(void) respondToEvent: (id) sender{ //theoretically? ... please? } } BONUS: What is the proper term for a "local" function? The usual term is
