selector

Have a look at this example code: class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let letterButton = UIButton.buttonWithType(.Custom) as UIButton self.view.addSubview(letterButton) letterButton.addTarget(self, action:Selector("buttonDidTap:"), forControlEvents: .TouchUpInside) } func buttonDidTap(button: UIButton!) { print(button.char) } } The target action for the UIButton works fine as long as Selector is public or internal , but if it's private , it crashes due to unrecognized selector sent to instance Is there any way I can achieve this ? I don't

I have applied a shape for a button like: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > <gradient android:startColor="#DD000000" android:endColor="#DD2d2d2d" android:angle="90"></gradient> <corners android:radius="15dip"></corners> </shape> Now I want to use a selector like: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/active" android:state_pressed="true" /> <item android:drawable="@drawable/passive"/> for this Button as well. Is it possible ...???

This question already has an answer here: How do I put codes from jsfiddle.net into my website? 1 answer All right, something REALLY frustrating and weird is going on. I have JQuery installed on my server, and I know it's imported correctly because when I run a simple... $(function() { alert('hello') }); It alerts "hello." However, when I try to use a css selector... $(".image").css("border","3px solid red"); It does not work! Yes, I'm 100% sure there is something with that class name in the file. Here's the real kicker, when I COPY PASTED my code into a jsFiddle it worked just fine. What

My document has a structure like this: { "Calibration": { "Presettings": { "Date": [ { "Value": "2016-09-02 10:11", "Type": "generated" }, { "Value": "2016-09-05", "Type": "schedule", "Duration": "5" } ] } } } How must I define the selector part of a query object to get all documents with dates (Value) less or equal to a given date and with Type=='generated' ? First, you need to create your index. I suggest that you create an index on the Calibration.Presettings.Date field . You can use the following JSON object to create it: { "index": { "fields": [ "_id", "Calibration.Presettings.Date.[]

I know how to put the icon on each tab, that is no problem. I also ran across this : [Stack Overflow thread on pretty much same thing][1] I followed one of the links from that question and found [this][2] Pretty much, it said to use a selector defined in the XML, sure, did that. But there is no id associated w/ it so I am not sure how to get the selector function as a drawable so I can use it as the icon for the tabs. Maybe I am going about this the wrong way. But this is what I have, and obviously missing something. <selector android:id="@+id/myselector" xmlns:android="http://schemas.android
