• Flexible Data source for Multi-Section Table View Controller

  - by TuanCM

  I have a TableViewController which display a list of NewsItem objects: @interface NewsItem : NSObject { NSString *feedID; NSString *title; NSDate *published; } I'm trying to implement a Table View Controller (multiple sections) that can display the list in two ways: One divide News Items into sections which based on Published Date The other would be based on FeedID (News source). And I don't know how to structure the data source so that the code is easy to maintain. I tried to put the list of News Items into a 2 dimension Array in this case is a NSMutableArray of NSArray objects. However I got some objc_exception_throw and I don't think this is flexible enough. Could you guys give me some ideas?

• testing controller action which returns RedirectToRouteResult

  - by csetzkorn

  Hi, I have an action in my controller: RedirectToRouteResult Create(UserDTO UserDTO) Which at some point decides with which HTML to respond after a post request by redirecting to an action: return ModelState.IsValid ? RedirectToAction("ThanksCreate") : RedirectToAction("Register"); In my unit tests I would like to get hold of the ‘views’ modelstate somehow like this: var modelState = result.ViewData.ModelState; Assert.IsFalse( modelState.IsValid ); where ‘result’ (ViewResult) is the result of the action ‘Create’ depending on the submitted DTO. My dilemma is that my action ‘returns’ a RedirectToRouteResult which I thought is quite nice but it might not be testable or is it? How could I get hold of the ModelState in my scenario? Thanks. Best wishes, Christian enter code here

• Trouble setting FIrst view controller which will appear on App Startup

  - by Matte.Car

  I'm setting setting FIrst view controller which will appear on my App Startup. It should appear an UIView first time as a tutorial and, from second time, another standard view. In AppDelegate I wrote this: #import "AppDelegate.h" #import "TabBarController.h" #import "TutorialController.h" @implementation AppDelegate TabBarController * viewControllerStandard; // standard view TutorialController * viewControllerFirst; // tutorial view @synthesize window; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if ([@"1" isEqualToString:[[NSUserDefaults standardUserDefaults] objectForKey:@"Startup"]]) { window.rootViewController = viewControllerStandard; } else { window.rootViewController = viewControllerFirst; } [window makeKeyAndVisible]; return YES; } It doesn't return any alert but, launching app, after splashscreen, it appear only a black screen. Without that codes everything works fine. What could be wrong? Thank you!

• Angular function constructor in Controller

  - by BigHeadCreations

  In normal JS I can do this: function Droppable() { this.relevant = true; this.uuid = generateUUID(); }; var generateUUID = function() { return '12345'; } console.log(new Droppable); // returns Droppable {relevant: true, uuid: "12345"} But in Angular I have this: angular.module('myApp').controller('MyCtrl', ['$scope', function($scope) { function Droppable() { this.relevant = true; this.uuid = generateUUID(); } var generateUUID = function() { return '12345'; } // initalize droppable areas $scope.region1 = [new Droppable]; $scope.region2 = [new Droppable]; $scope.region3 = [new Droppable]; }]); I am trying to make 3 droppable areas all with a UUID. But when I do this I get 'undefined is not a function' referring to the line this.uuid = generateUUID(); in function Droppable() {...} Why is that?

• Controller not accepting params value but the same value hard coded is accepted

  - by Numbers

  Rails.logger.info(params[:question]) => {"title"=>"katt"} @question_list.questions.create(params[:question]) => ActiveModel::ForbiddenAttributesError (ActiveModel::ForbiddenAttributesError) @question_list.questions.create("title"=>"katt") # SUCCES!

• iPhone: Switching Views From Outside Root Controller

  - by senfo

  I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

• Map a struts2 action result to a controller instead of a jsp

  - by Jim

  Hello, I'm working on on a site built using struts2. The vast majority of our targets generate xml, so mapping the result to a jsp page makes sense. A couple of our targets actually generated binaries. I'm wondering if there is a convenient way to say that the result should come from a servlet/controller instead of a jsp. Obviously this could be done by modifying the web.xml so the struts filter doesn't apply to those targets and mapping those targets as servlets, but this is non-ideal. Currently, the struts filter applies to the entire site, and we would like to keep it that way. Ideas? Thanks!

• detecting when nav controller popped to root

  - by phil swenson

  Here is my code: SignupController* signupController = [[SignupController alloc] initWithNibName:@"SignupController" bundle:nil]; [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; self.navigationController.title = @"MyNavController"; [self.navigationController pushViewController:signupController animated:YES]; [signupController release]; Unfortunately for me calling pushViewController is not synchronous, so the next line ([signupController release]) is executed immediately. I need to detect hen the signupController has popped back to the root so I can take the data from the signup controller and do a registration or login. Any ideas? Thanks

• FJSTransitionController setup and use in View Controller not main app delegate

  - by elliotrock

  I am trying to set up Corey Floyd's FJSTransitionController. My app uses a main view controller to manage the main view navigation. I also went through the source to fix it for ARC. Followed instructions and in my main delegate .h I have in the usual spots: FJTransitionController* mainTransitionController; @property (nonatomic,retain) FJTransitionController* mainTransitionController; delegate .m has the following @synthesize mainTransitionController And in the - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions mainTransitionController=[[FJTransitionController alloc] init]; // do I need to instantise? [self.window addSubview:mainTransitionController.view]; [mainTransitionController setViewControllerClass:[[mainViewController sendMissionsPanelViewController] class] forKey:@"missionView"]; The last line is complaining that there is no @interface for FJTransitionController? Any help please.

• Rails controller processing as HTML instead of XML

  - by Andy

  I've recently upgraded from Ruby 1.8.6 and Rails 2.3.4 to Ruby 1.9 and Rails 3.0.3. I have the following controller: class ChartController < ApplicationController before_filter :login_required respond_to :html, :xml def load_progress chart.add( :series, "Memorized", y_memorized ) chart.add( :series, "Learning", y_learning ) chart.add( :series, "Mins / Day", y_time ) chart.add( :user_data, :secondary_y_interval, time_axis_interval ) respond_to do |fmt| fmt.xml { render :xml => chart.to_xml } end # Also tried # respond_with chart end end However, when I call the 'load_progress method' I get the following: Started GET "/load_progress.xml" for 127.0.0. Processing by ChartController#load_progress as HTML Completed 406 Not Acceptable in 251ms I have also tried changing the respond_to block to respond_with chart But I get the same response. I've read all the new Rails documentation on the new respond_with format but I can't seem to elicit an XML response. Am desperately hoping someone has some ideas.

• How to connect Model through Controller to View using bindings?

  - by Paperflyer

  I have an NSTextField in my view. Its value is bound to an NSNumber *number in my controller. The controller simply calls through to the model (value) to get the appropriate value. // In the controller - (NSNumber *)number { return [NSNumber numberWithFloat:[model value]]; } - (void)setNumber:(NSNumber *)aNumber { [model setValue:[aNumber floatValue]]; } This is fine, only the controller is not notified of model changes and thus, changing the value in the model does not update the NSTextField. The only other option I can think of is to have the model notify the controller and the controller manually update the view through an Outlet. But this circumvents the binding. // In the model, after value change [[NSNotificationCenter defaultCenter] postNotificationName:@"ValueChanged" object:self]; // In the controller, after being notified - (void)updateView:(NSNotification *)aNotification { [myTextField setFloatValue:[model value]]; } Is there a better, binding-aware way to implement this communication?
