  • How to get a reference to a method's caller object from within the method in Objective-C

    - by shakeelw
    Hi guys. I have a few text fields and text views on my application's view. The keyboard comes up when I click in anyone of them. I have a method that gets called when any one of these objects is tapped in. However, I would like the method to execute its code only if the a certain Text Field(s) or a certain Text View(s) is tapped in. I would therefore like to have something like this in the method body: { if(currentField != mySpecialField) {return;} //Rest of the method code... } Now, my question is, how do I get a reference to the currently tapped in field so that I can perform the if-check. Thanks guys. I'm a total noobee in Objective-C. :(

  • Why would a "view" object in Interface Builder prevent my didFinishLaunchingWithOptions method from

    - by BeachRunnerJoe
    You may have already come across some of my other questions related to question, but I was having an issue with a SplitView iPad app where my application:didFinishLaunchingWithOptions method stopped executing after I went into Interface Builder and changed around the structure of my apps interface. I couldn't figure out what was preventing my didFinishLauchingWithOptions method from executing, but then I removed a "view" object I had in my view heirarchy (shown below) and suddenly my didFinishLauchingWithOptions method started executing again. I've moved passed it now, but I'm still unclear why that would cause the problem. Any ideas why that "view" object would prevent the didFinishLaunchingWithOptions method from executing?

  • BeginInvoke not invoking the target method in Release build

    - by Elan
    I have a method, which I wish to execute on the UI message pump and thus do the following: private void SomeMethod() { BeginInvoke(new MethodInvoker(MethodToInvoke)); } private void MethodToInvoke() { // This method contains code that I wish to execute on UI message pump. } Now, the above works just fine when I create a Debug build of the project. However, when I create a Release build, the "MethodToInvoke" method does not get invoked. Does anyone have any idea why this might be? Thanks, Elan

  • Cannot call action method 'System.Web.Mvc.PartialViewResult Foo[T](T)' on controller 'Controller' be

    - by MedicineMan
    Cannot call action method 'System.Web.Mvc.PartialViewResult FooT' on controller 'Controller' because the action method is a generic method <% Html.RenderAction("Foo", model = Model}); %> Is there a workaround for this limitation on ASP MVC 2? I would really prefer to use a generic. The workaround that I have come up with is to change the model type to be an object. It works, but is not preferred: public PartialViewResult Foo<T>(T model) where T : class { // do stuff }

  • Ajax method call

    - by LooDaFunk
    Hi, I am trying to call a simple method in my code behind using Jquery with Ajax. But I get a 404 not found exception everytime. Unfortunately this is a web forms solution. So I dont have all the perks of MVC :( It does get into the javascript method and gives the alert but won't go into my c# method. My previous experience of using this Jquery method is in an MVC website. Is it compatible with webforms sites? Here is the code: http://pastebin.com/Xdey4XTS Thanks Merry Christmas!

  • How do I use .htaccess to redirect to a URL containing HTTP_HOST?

    - by Jon Cram
    Problem I need to redirect some short convenience URLs to longer actual URLs. The site in question uses a set of subdomains to identify a set of development or live versions. I would like the URL to which certain requests are redirected to include the HTTP_HOST such that I don't have to create a custom .htaccess file for each host. Host-specific Example (snipped from .htaccess file) Redirect /terms http://support.dev01.example.com/articles/terms/ This example works fine for the development version running at dev01.example.com. If I use the same line in the main .htaccess file for the development version running under dev02.example.com I'd end up being redirected to the wrong place. Ideal rule (not sure of the correct syntax) Redirect /terms http://support.{HTTP_HOST}/articles/terms/ This rule does not work and merely serves as an example of what I'd like to achieve. I could then use the exact same rule under many different hosts and get the correct result. Answers? Can this be done with mod_alias or does it require the more complex mod_rewrite? How can this be achieved using mod_alias or mod_rewrite? I'd prefer a mod_alias solution if possible. Clarifications I'm not staying on the same server. I'd like: http://example.com/terms/ - http://support.example.com/articles/terms/ https://secure.example.com/terms/ - http://support.example.com/articles/terms/ http://dev.example.com/terms/ - http://support.dev.example.com/articles/terms/ https://secure.dev.example.com/terms/ - http://support.dev.example.com/articles/terms/ I'd like to be able to use the same rule in the .htaccess file on both example.com and dev.example.com. In this situation I'd need to be able to refer to the HTTP_HOST as a variable rather than specifying it literally in the URL to which requests are redirected. I'll investigate the HTTP_HOST parameter as suggested but was hoping for a working example.

  • How to invoke a method with a generic return type using reflection

    - by Andre Luus
    Hi there! I'm trying to invoke a method with reflection that has a generic return type, like this: public class SomeClass<T> { public List<T> GetStuff(); } I get an instance of SomeClass with a call to a Repository's GetClass<T> generic method. MethodInfo lGetSomeClassMethodInfo = typeof(IRepository) .GetMethod("GetClass") .MakeGenericMethod(typeof(SomeClass<>); object lSomeClassInstance = lGetSomeClassMethodInfo.Invoke( lRepositoryInstance, null); After that, I this is where I try to invoke the GetStuff method: typeof(SomeClass<>).GetMethod("GetStuff").Invoke(lSomeClassInstance, null) I get an exception about the fact that the method has generic arguments. However, I can't use MakeGenericMethod to resolve the return type. Also, if instead of typeof(SomeClass<>) I use lSomeClassInstance.GetType() (which should have resolved types) GetMethod("GetStuff") returns null! UPDATE I have found the solution and will post the answer shortly.

  • Running Send_SMS method from BroadcastReceiver

    - by burmat
    My application is an auto-reply application for text messages. I have a BroadcastReceiver for when a message arrives, and I need it to run a public method (Send_SMS). SMS_Sender.sendSMS(phoneNumber, messageText); does not work however, and eclipse wants to change my method to static. This would not be an issue if I did not have more receivers that catch when the message is sent/delivered/etc in this class. These receivers are then errors for being contained in a static method. So my question is, how do I run this method from a broadcast receiver so I can send the auto reply whenever it is triggered with a received message? -Thank you in advance, Nate

  • Overriding a method in statically created objects

    - by I82Much
    All, Due to a bug in a library I'm using, I need to override the dispose() method on all objects extending a certain class and make it a NO-OP. I know that if I'm making new instances of the classes directly, this is easy to do: layerManager = new LayerManagerLayer(wwd) { @Override public void dispose() {} }; The problem is that a lot of the object instances I get are not directly constructed by my client code, but instead are created via static library method calls. // Here I want to override the dispose method, but I cannot. Layer l = ShapefileLoader.makeShapefileLayer(this.getClass().getResource("polylines10.shp")); Is there a way I can inject my dispose method into that statically created object without modifying the original sourcecode?

  • Git: can I store known repositories along the repository?

    - by 0x6adb015
    I am setting up a Git repository. I know you can add repositories using git config --global, but is there a way that those known repositories gets cloned by users? The goal would be that once the repo gets cloned by userz, they can push to other repos just by their aliases. For example, I add git://X/mobility.git as X to the repo (somehow), a user clone it from git://Y, but then can do git push X without previously doing the git config. How to do that?

  • Error message when trying to insert method into touchesBegan

    - by Rob
    I am trying to create a new method within my TapDetectingImageView file and it's giving me a warning that it cannot find the method even though I have it declared in the .h file. The specific three warnings all point to the @end line in the .m file when I build it and they say: "Incomplete implementation of class 'TapDetectingImageView' ; 'Method definition for '-functionA:' not found" ; "Method definition for '-functionB:' not found" What am I missing? Am I not allowed to do this in a protocol file like TapDetectingImageView? In my .h file is: @interface TapDetectingImageView : UIImageView <AVAudioPlayerDelegate> { id <TapDetectingImageViewDelegate> delegate; } @property (nonatomic, assign) id <TapDetectingImageViewDelegate> delegate; -(void) functionA:(NSString*)aVariable; -(void) functionB:(NSString*)aVariable; @end In my .m file is: -(void)functionA:(NSString*)aVariable { // do stuff in this function with aVariable } -(void)functionB:(NSString*)aVariable { // do stuff in this function with aVariable }
