  • iOS - Prompt User to Update to Latest App Version

    - by Kevin_TA
    Is there any method or plugin available that will alert the user to upgrade an app if the version they are using is not the latest? I suppose I could ping a web service to check what the current version is and compare with the user's version and go from there. As an aside, is there a way to check the current version of the app (some property I don't know about) or do you simply have to hardcode the version as some float variable or something? Thanks

  • Is it even possible to change a UIButtons background color??

    - by dubbeat
    Hey, This one has me stumped. Is it possible at all to change the background color of a UIButton in Cocoa for iphone. I've tried setting the background color but it only changes the corners. SetBackgroundColor seems to be the only method available for such things. Please refer to my screen shot [random setBackgroundColor:[UIColor blueColor]]; [random.titleLabel setBackgroundColor:[UIColor blueColor]];

  • Is it a good or bad practice to call instance methods from a java constructor?

    - by Steve
    There are several different ways I can initialize complex objects (with injected dependencies and required set-up of injected members), are all seem reasonable, but have various advantages and disadvantages. I'll give a concrete example: final class MyClass { private final Dependency dependency; @Inject public MyClass(Dependency dependency) { this.dependency = dependency; dependency.addHandler(new Handler() { @Override void handle(int foo) { MyClass.this.doSomething(foo); } }); doSomething(0); } private void doSomething(int foo) { dependency.doSomethingElse(foo+1); } } As you can see, the constructor does 3 things, including calling an instance method. I've been told that calling instance methods from a constructor is unsafe because it circumvents the compiler's checks for uninitialized members. I.e. I could have called doSomething(0) before setting this.dependency, which would have compiled but not worked. What is the best way to refactor this? Make doSomething static and pass in the dependency explicitly? In my actual case I have three instance methods and three member fields that all depend on one another, so this seems like a lot of extra boilerplate to make all three of these static. Move the addHandler and doSomething into an @Inject public void init() method. While use with Guice will be transparent, it requires any manual construction to be sure to call init() or else the object won't be fully-functional if someone forgets. Also, this exposes more of the API, both of which seem like bad ideas. Wrap a nested class to keep the dependency to make sure it behaves properly without exposing additional API:class DependencyManager { private final Dependency dependency; public DependecyManager(Dependency dependency) { ... } public doSomething(int foo) { ... } } @Inject public MyClass(Dependency dependency) { DependencyManager manager = new DependencyManager(dependency); manager.doSomething(0); } This pulls instance methods out of all constructors, but generates an extra layer of classes, and when I already had inner and anonymous classes (e.g. that handler) it can become confusing - when I tried this I was told to move the DependencyManager to a separate file, which is also distasteful because it's now multiple files to do a single thing. So what is the preferred way to deal with this sort of situation?

  • How to call a prototyped function from within the prototyped "class"?

    - by Jorge
    function FakeClass(){}; FakeClass.prototype.someMethod = function(){}; FakeClass.prototype.otherMethod = function(){ //need to call someMethod() here. } I need to call someMethod from otherMethod, but apparently it doesn't work. If i build it as a single function (not prototyped), i can call it, but calling a prototyped does not work. How can i do it as if i was treating the function just like a class method?

  • How to disconnect an existing ruby sequel connection to a database?

    - by MG
    I mean the one which was previously established as DB = Sequel.sqlite('my_blog.db') or DB = Sequel.connect('postgres://user:password@localhost/my_db') or DB = Sequel.postgres('my_db', :user => 'user', :password => 'password', :host => 'localhost') or etcetera. The Sequel::Database class has no public instance method called "disconnect" or so though it has "connect" one. Maybe somebody already faced that problem. I would appreciate any idea.

  • How to display QuickContact card from widget

    - by alejom99
    I have a widget that displays the picture of some of my contacts and I would like to display the QuickContact card when the user taps on one of the pictures. I know I should be using the method ContactsContract.QuickContact.showQuickContact(), but it requires a View or a Rect as one of the input parameters. My problem is that Widgets only have RemoteViews, so I'm no sure what to pass as the View or Rect parameter. Any ideas would be appreciated.

  • Can first descendent be selected directly?

    - by Ben Huh
    I am currently using find() and first() method to select the first descendent element from each of the <div> elements that contains the parent class. But I find this quite cumbersome since find() method would produce a set of matched elements before the first element is being picked. The following is the skeleton of my code: HTML <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=non-parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> // .....the list continues Javascript $('.parent').each(function() { $(this).find('ul li').first().css('color', 'red'); // do other stuff within each loop }); I have seen people using $(".parent li:first") selector. But, because I am doing it in a loop, I am not sure how or whether if this could be done and would like some advice. Thanks.

  • Spring.Net how does WebApplicationContext.GetObject handle concurrent requests?

    - by Alfamale
    Apologies if I have missed something obvious here but having gone through the documentation, forums and googled for a number of hours, I just can't find a definitive answer to the following questions: How does the WebApplicationContext.GetObject() method handle concurrent requests? Are the requests serialized or executed in parallel? Is there any performance data available to demonstrate how it behaves under load? Thanks in advance for your help, Andrew

  • Disable iOS keyboard (don't show it at all) in phonegap

    - by lashleigh
    If I were writing a native app I would try the solution given here which says: Try to implement the following method in text view's delegate: - (BOOL)textViewShouldBeginEditing:(UITextView *)textView{ return NO; } Unfortunately I need to use phonegap, so I don't have a text view to manipulate. It would be great if I could permanently suppress the keyboard in this app. We've got some custom on screen keyboard that people are supposed to use instead. So, any idea how to disable the popup keyboard completely?

  • Django1.1 file based session backend multi-threaded solution

    - by Satoru.Logic
    Hi, all. I read django.contrib.sessions.backend.file today, in the save method of SessionStore there is something as the following that's used to achieve multi-threaded saving integrity: output_file_fd, output_file_name = tempfile.mkstemp(dir=dir, prefix=prefix + '_out_') renamed = False try: try: os.write(output_file_fd, self.encode(session_data)) finally: os.close(output_file_fd) os.rename(output_file_name, session_file_name) renamed = True finally: if not renamed: os.unlink(output_file_name) I don't quite understand how this solve the integrity problem.

  • How to calculate a latlng on google map ceartain distance away from another?

    - by Rene Saarsoo
    To draw a circle on map I have a center GLatLng (A) and a radius (r) in meters. Here's a diagram: ----------- --/ \-- -/ \- / \ / \ / r \ | *-------------* \ A / B \ / \ / -\ /- --\ /-- ----------- How to calculate the GLatLng at position B? Assuming that r is parallel to the equator. Getting the radius when A and B is given is trivial using the GLatLng.distanceFrom() method - but doing it the other way around not so. Seems that I need to do some heavier math.
