selector

I'm trying to add in my app the possibility to dismiss the keyboard when the user taps somewhere else out of the text fields. I'm implementing this functionality using UITapGestureRecognizer. I create a new UITapGestureRecognizer object using the Unrecognized selector with UITapGestureRecognizer(target: Any?, action: Selector?) and set the action parameter to a function that resigns the first responder of both the text fields I'm using in this view. I set everything properly adding the keyword @objc before the method I pass as action and using the #selector(dismissKeyboard) form, but when I

This should be easy, but I can't seem to get it right. var totalHours = 0; this.$(".timesheet-daily-input").each( function () { var inputValue = $(this).text(); var hours = parseInt(inputValue); totalHours += (hours == null) ? 0 : hours; }); I've tried $(this).val() and $(this).html() as well, but can't get the values out of the input fields. Edit: Apologies, I knew I was forgetting to mention something. The "this." at the start of the each loop is because I am using backbone's models and collections. The first "this." refers to the specific model in question. It loops through the proper

I created a simple singleton and run method in it: - (void)run { static int times = 0; NSLog(@"times = %d", times++); [self performSelector:@selector(run) withObject:nil afterDelay:MIN_DELAY]; } But it doesn't work properly. It is executed only once. But if I replace performSelector:withObject:afterDelay: with performSelector: then it will be called a lot of times (but I need a delay between calls). So why method performSelector:withObject:afterDelay: doesn't work? And can I use this method at all? Calls to -performSelector:withObject:afterDelay: require a run loop. Console applications do not

In the Google Translator I've made a second instance of Google Translate with var makediv = document.createElement("secondinstance"); makediv.innerHTML = '<iframe id="iframenaturalID" width="1500" height="300" src="https://translate.google.com"></iframe>'; makediv.setAttribute("id", "iframeID"); var getRef = document.getElementById("gt-c"); var parentDiv = getRef.parentNode; parentDiv.insertBefore(makediv, getRef); And I'm trying to copy text from auto-correction of the first instance to the textarea of the second instance: I'm trying this (this code works if I just copy html within the Chrome

I'm trying to implement a text-highlighting search script on a Wordpress site for a client. The script executes a regex search on the raw HTML data from the webpage, adding a span tag/css element to any part of the document that matches the query. However, I'm trying to search on some multi-level HTML (headers, etc), and some of the tags have descriptive id and class names, which actually end up getting found by the script and highlighted. This results in some wonky behavior when the script finds a match in one of the id names (ex: a search for "Cont" would wrap turn <div id="Container"> into

I am trying to persist the UISwitch state in my settings view of my application. Basically it is a UITableView and contains a few switches to get the user preferences. The below code explains how the switches are constructed (only one switch construct is given below, others are also constructed the sameway). if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:SomeIdentifierB] autorelease]; if (syncStartupSwitch) { syncSwitch.on = YES; }else { syncSwitch.on = NO; } [syncSwitch addTarget:self action:@selector(syncAtStartup:) forControlEvents
