iphone - converting NSString to precise number for performSelector: afterDelay: -

-

I am communicating with a webservice to get the numeric value in my function as an NSString This number tells me the exact time to wait until taking another action, and it is important that this is accurate.

As an example, if the string is "89283", that means that I should wait 89.283 seconds. So I would like to know the best way in Objective-C so that the iPhone can convert this string to an exact value that I can pass to display: later: function. Here's my sample code, but I'm making an accurate estimate of it. 

  NSString * myDelayString = @ "89283"; Int myDelay = [myDelayString intValue] / 1000; [Selector to self: Object with @centor (myfunction): after zero: my dell];

I think my della value should actually be an NSTimeInterval, but I'm not sure how to make a string with me thank you in advanced.

There is a code with the change to allow double precision. 

  NSString * myDelayString = @ "89283"; NSTimeInterval myDelay = [myDelayString doubleValue] / 1000; [Selector to self: Object with @centor (myfunction): after zero: my dell];

Use double values ​​to get the string as double so that you can avoid integer division. The type of NSTimeInterval is defined as double on the iPhone, so you can add double results in it and then you can give it later: Part of the selector.

Is there an open source WebSockets (JavaScript) XMPP library? -

-
Has anyone written the open source XMPP library that uses the websacet and is being run by a browser? We do not yet have a standard XMPP that can enforce the server, Must be adequately faced before it may be necessary The first step is to eliminate WebSAT standardization. It seems that it can be in an IETF Haib working group, which has not been approved by the IESG so far in the writing time (see) a few weeks ago (Hiroshima), a hybrid bird-of-a-feather in IETF ( BOF), which went very well. WebSketches have a constant reference, and it seems to be systematically organized, one will make XMPP binding for webmasters, possibly with a bar for every webset frame. Edit: Jack Moffitt has written an IETF can be used with the first pass on a protocol. Warning . It is still likely to change fast enough, only apply it if you are ready to wrap it completely later.

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}

-
Just want to know how I will create UIPickerView in a UIActionSheet with a simple array. Well, I really know how to put it in an action sheet but I like my way because it is more for my app, thanks, but I I also want to know how to put options in UIPKviewView, I just have an array with colors already on top of that part: red, green, blue, yellow, black, etc. in this, but I want to know how it In the preview d L'be if I am using the already Instifrem:? Please help anyone. I know that this is a stupid question, but I'm cheating my head on my $$$$$$ MacBook. Instead you want to do this, create your UIPickerView interface builder and have it in your view controller Connect to the outlet. Add it as a subview of your main view and set its frame coordinates so that it is offset right below the edge, x = 0, y = 480 Then, when you want to display a picker, animate it like something with the screen: [UIView startup permissions: zero reference: zero]; [Color picture setfr...
