  • Make an NSString accessible in the whole class

    - by OhhMee
    Hello, I want to know how can I make an NSString accessible in the whole class. Say I have these codes: - (void) init { NSArray *elements = [xpathParser search:@"//foo"]; TFHppleElement *element = [elements objectAtIndex:0]; NSString *data = [element content]; NSArray *elements1 = [xpathParser search:@"//foo2"]; TFHppleElement *element2 = [elements1 objectAtIndex:0]; NSString *data2 = [element2 content]; } And I want to use data & data2 in the whole class, how can I do that? I want to show results here: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. switch (indexPath.row) { case 0 : cell.textLabel.text = (@"%@", data); break; case 1: cell.textLabel.text = (@"%@", data2); break; } // Email & Password Section return cell; }

  • Int Showing as Long Odd Value

    - by Josh Kahane
    Hi I am trying to send an int in my iphone game for game center multiplayer. The integer is coming up and appearing as an odd long integer value rather than the expected one. I have this in my .h: typedef enum { kPacketTypeScore, } EPacketTypes; typedef struct { EPacketTypes type; size_t size; } SPacketInfo; typedef struct { SPacketInfo packetInfo; int score; } SScorePacket; Then .m: Sending data: scoreData *score = [scoreData sharedData]; SScorePacket packet; packet.packetInfo.type = kPacketTypeScore; packet.packetInfo.size = sizeof(SScorePacket); packet.score = score.score; NSData* dataToSend = [NSData dataWithBytes:&packet length:packet.packetInfo.size]; NSError *error; [self.myMatch sendDataToAllPlayers: dataToSend withDataMode: GKMatchSendDataUnreliable error:&error]; if (error != nil) { // handle the error } Receiving: SPacketInfo* packet = (SPacketInfo*)[data bytes]; switch (packet->type) { case kPacketTypeScore: { SScorePacket* scorePacket = (SScorePacket*)packet; scoreData *score = [scoreData sharedData]; [scoreLabel setString:[NSString stringWithFormat:@"You: %d Challenger: %d", score.score, scorePacket]]; break; } default: CCLOG(@"received unknown packet type %i (size: %u)", packet->type, packet->size); break; } Any ideas? Thanks.

  • Invoking [SKProductsRequest start] hangs on iOS 4.0

    - by figelwump
    Encountering an issue with SKProductsRequest that is specific to iOS 4.0. The problematic code: - (void)requestProductData { NSSet *productIdentifiers = [NSSet setWithObjects:kLimitedDaysUpgradeProductId, kUnlimitedUpgradeProductId, nil]; self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; self.productsRequest.delegate = self; [self.productsRequest start]; } - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { NSLog(@"didReceiveResponse"); } When [SKProductsRequest start] is invoked, the productsRequest:didReceiveResponse: delegate method is never invoked; further, the entire app hangs and is completely unresponsive to input. Obviously, this is a huge issue for our iOS 4.0 users as it not only breaks payments but makes the app completely unusable. Some other things to note: this only happens on iOS 4.0; iOS 4.2, 3.x are fine. Also: if the delegate is not set on the SKProductsRequest (i.e. comment out the line "self.productsRequest.delegate = self;"), the app doesn't hang (but of course in that case we have no way of getting the product info). Also, the problem still reproduces with everything stripped out of the productsRequest:didReceiveResponse: callback (that method never actually gets called). Finally, if the productIdentifiers NSSet object is initialized to an empty set, the hang doesn't occur. Has anybody else experienced this? Any ideas/thoughts on what could be going on here, and how we might be able to work around this?

  • How to display controllers with proper aligning in iPhone screen ?

    - by chatcja
    I have a issue of displaying information in iPhone screen. Case is as follows. I crated a view-based application in Xcode name as myView. Then open myViewViewController.xib interface builder, change back groung color and added label at top-let (0, 0) of the view. Then I add new file named as myView2ViewController, which is subclass of UIViewController and corresponding XIB also generated. Open myView2ViewController in IB and added a label at top-left as previous. Also changed the background color. In the "applicationDidFinishLaunching" of AppDeligate do following myView2ViewController *mView = [[myView2ViewController alloc] initWithNibName:@"myView2ViewController" bundle:nil]; [window addSubview:mView.view]; When I run the application, it is shown as upper part of the Label is sheared. It seems as whole UI has been moved 20 px upper (Because, there is a horizontal space in the bottom). I guess this is due to some positioning. But still I could not found any way to fix it. Hope somebody will help me to identify this issue !!

  • Utility App with Navigation Controller and Table View on FlipSide.

    - by wdt
    Hi All. I am relatively new to the whole MVC way of looking at things. I have an application that is based on the "Utility" Application template. Everything in the MainView and FlipsideView is working great but now I need to add a TableView and Navigation Controller to the flipside. Without the navigation bar being on the MainView. So only once the user has tapped the info light button will the nav bar display on the flipside with a table view. I have been able to impliment the Table View on the side and populate it with data from an array. I am now struggling to link in a navigation controller so that the tableview can become interactive. When I place the nav bar code into the app delegate it appears on the MainView and not the flipside view. Where do I place the navigation bar code so that it will display on the flipsideview. I cannt seem to get the code in the right place. Also I am not sure I have the right code, do I put the UINavigationController code in the FlipSideViewController.m ? I am not grasping the concept of the naivgation controller fully I think . . . Here is the code to bring up the FlipView - (IBAction)showInfo { TableViewController *controller = [[TableViewController alloc] initWithNibName:@"TableViewController" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Now I need to get the TableViewController to have a navigation controller and a table view Thanks in advance.

  • Add a smaller subView with new origin

    - by ReachWest
    I can't get my head around this - I know it must be simple.. I'm starting to feel pretty stupid. I have two viewControllers. MainViewController.h/m and LevelsViewController.h/m I want to add a subView from the LevelsViewController class and a view that is built in IB called levelsView. I am calling this from the MainViewController.m file. The levelsView is only 200x200 pixels and I want to offset it from the frame origin of the superView by x=140 pixels and y=50 pixels. I have this working - the view displays, but I can't figure out how to offset it. It only shows up at the 0,0 superView frame origin. (The superView shows below it, which is what I want). Here is the code I call in the method in the MainViewController.m that displays the levelsView.(I have commented out some of the things I have tried - but throws this error: error: request for member 'frame' in 'myLevelsView', which is of non-class type 'LevelsViewController*' ) - (void) displayLevelsPage { if (self.theLevelsView == nil) // Does not yet exist - therefore create { LevelsViewController * myLevelsView = [[LevelsViewController alloc] initWithNibName:@"levelsView" bundle:[NSBundle mainBundle]]; NSLog(@"NEW theLevelsView instance created!"); CGRect frame2 = CGRectMake(140, 50, 200, 200); //myLevelsView.frame = frame2; self.theLevelsView = myLevelsView; [myLevelsView release]; } [self.view addSubview: theLevelsView.view]; NSLog(@"Levels View has been activated"); } Any insight would be appreciated.

  • Agile web development with rails

    - by Steve
    Hi.. This code is from the agile web development with rails book.. I don't understand this part of the code... User is a model which has name,hashed_password,salt as its fields. But in the code they are mentioning about password and password confirmation, while there are no such fields in the model. Model has only hashed_password. I am sure mistake is with me. Please clear this for me :) User Model has name,hashed_password,salt.

  • iPhone loading view from nib only works once

    - by The Swissdude
    Hi Forum I'm trying to add a «loader-view» to my app which shows a spinner while doing stuff. This works fine the first time, but it doesn't work a second time. here's what I do: I have a viewController for the spinner (spinnerViewController) and a nib-file which I made in IB (spinner.xib). I load the nib in the viewDidLoad-event: spinnerView = [[spinnerViewController alloc] initWithNibName:@"spinner" bundle:nil]; [spinnerView retain]; spinnerView is declared in the .h-file (spinnerViewController *spinnerView;) next, I show the spinner-view: [self.view addSubview:spinnerView.view]; [self.view bringSubviewToFront:spinnerView.view]; which works fine... And now the trouble starts. No matter what I do, I can't show the spinner view again. I tried just hiding it (self.view sendSubViewToBack: spinnerView.view) which works for hiding, but when I try to bring it to the front again (self.view bringSubViewToFront: spinnerView.view) it doesn't work. I also tried removing the spinner-view and add it again with no success (within the spinnerViewController: [self.view removeFromSuperview] and to show it again [self.view addSubview... ) Any ideas what I'm doing wrong??? ;) Thanks for the help!

  • A scheme to show picture

    - by luoliyong
    I have a requirement that need me to show picture using one canvas. All the operation will be done on this canvas, include change the picture (This picture is made of lines, rectangular and so on. Draw these lines or rectangular will use the base method). In China, we called use double buffer(CGBitmapContextCreate), one of the scheme like this // create the bitmap context CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(nil,27,27,8,0, colorSpace,kCGImageAlphaPremultipliedLast); CFRelease(colorSpace); Maybe now it is not very clear. I talk about the project. The project has an engine, That will call methed draw line, draw round ,draw rectangular according user's input, this lines, rounds, rectangular will make up a picture? and then usr changes his input, the picture also will change, the engine accept usr's input, and draw picture. and the engine inits only once. I hope you can understand what I say, and give me some advice. Thanks.

  • How can I get a default value in some instances but not others?

    - by Connor Wagner
    I am making an iPhone app and want to use an 'if' statement and a boolean to set default values in some instances but not others... is this possible? Are there alternative options if it is not possible? In the MainViewController.m I have: @interface MainViewController (){ BOOL moveOver; } [...] - (void)viewDidLoad { [super viewDidLoad]; _label.text = [NSString stringWithFormat:@"%i", computerSpeed]; } } [...] - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { [self dismissViewControllerAnimated:YES completion:nil]; moveOver = true; } The problem that it is redefined when the ViewDidLoad runs... I need a statement that will not redefine when the ViewDidLoad runs. I have something that I feel like is much closer to working... In the ViewDidLoad I have: if (playToInt != 10 || computerMoveSpeed != 3) { moveOver = TRUE; } which connects to my created method, gameLoop. It has if (moveOver == false) { computerMoveSpeed = 3; playToInt = 10; } I have tried putting the code in the gameLoop into the ViewDidLoad, but it had the same effect. When moveOver was false, the computerMoveSpeed and the playToInt were both seemingly 0. I have two UITextFields and typed 10 and 3 in them... does this not set it to the default? It seems to set the default to 0 for both, how do I change this? THIS IS A DIFFERENT ISSUE THAN THE THREE BOOLEAN VALUES QUESTION

  • Retrieving Relationships from within two arrays of pointers

    - by DanF
    In a portion of a program I'm working on, I need to count all the times each person has worked on projects with each other person. Let's say we have "Employee" entities and "Session" entities. In each session, there are four project types, "A", "B", "C", & "D", each a many-to-many relationship to Employees. I'm making a loop to systematically review every person a selected person has worked with. First, I put all their project types in a single array, so it's easier to loop through, but by the time I ask the last nested Project for its Employee members, I get an "unrecognized selector" error. IBOutlet NSArrayController * list; int x; for(x = 0; x < [list count]; x++){ NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectAs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectBs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectCs"]; NSArray *A = [[list objectAtIndex:x] valueForKey:@"projectDs"]; NSArray *masterList = [[NSArray alloc] initWithObjects: projectAs, projectBs, projectCs, projectDs, nil]; int y; for(y = 0; y < [masterList count]; y++){ int z; for(z = 0; z < [[masterlist objectAtIndex:y] count]; z++){ //And now to make an Array of this employee's partners on the selected object, to run comparisons on. //I also have an array of keys for each session's teams, so that's what I'm referencing here: NSArray * thisTeam = [list objectAtIndex:y] objectAtIndex:z] valueForKey:projectKey]; This throws an exception... namely, -[_NSFaultingMutableSet objectAtIndex:]: unrecognized selector sent to instance What's wrong with that last Array creation?

  • Paged UIScrollView with UIImageViews only showing first UIImageVIew

  • SQLite3 database doesn't actually insert data - iPhone

    - by user334934
    I'm trying to add a new entry into my database, but it's not working. There are no errors thrown, and the code that is supposed to be executed after the insertion runs, meaning there are no errors with the query. But still, nothing is added to the database. I've tried both prepared statements and the simpler sqlite3_exec and it's the same result. I know my database is being loaded because the info for the tableview (and subsequent tableviews) are loaded from the database. The connection isn't the problem. Also, the log of the sqlite3_last_insert_rowid(db) returns the correct number for the next row. But still, the information is not saved. Here's my code: db = [Database openDatabase]; NSString *query = [NSString stringWithFormat:@"INSERT INTO lists (name) VALUES('%@')", newField.text]; NSLog(@"Query: %@",query); sqlite3_stmt *statement; if (sqlite3_prepare_v2(db, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { if(sqlite3_step(statement) == SQLITE_DONE){ NSLog(@"You created a new list!"); int newListId = sqlite3_last_insert_rowid(db); MyList *newList = [[MyList alloc] initWithName:newField.text idNumber:[NSNumber numberWithInt:newListId]]; [self.listArray addObject:newList]; [newList release]; [self.tableView reloadData]; sqlite3_finalize(statement); } else { NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(db)); } } [Database closeDatabase:db]; Again, no errors have been thrown. The prepare and step statements return SQLITE_OK and SQLITE_DONE respectively, yet nothing happens. Any help is appreciated!

  • how can I cache a partial retrieved through link_to_remote in rails?

    - by Angela
    I use link_to_remote to pull the dynamic contents of a partial onto the page. It's basically a long row from a database of "todo's" for the day. So as the person goes through and checks them off, I want to show the updated list with a line through those that are finished. Currently, I end up needing to click on the link_to_remote again after an item is ticked off, but would like it to redirect back to the "cached" page of to-do's but with the one item lined through. How do I do that? Here is the main view: <% @campaigns.each do |campaign| %> <!--link_to_remote(name, options = {}, html_options = nil)--> <tr><td> <%= link_to_remote(campaign.name, :update => "campaign_todo", :url => {:action => "campaign_todo", :id => campaign.id } ) %> </td></tr> <% end %> </table> <div id="campaign_todo"> </div> I'd like when the New/Create actions are done to go back to the page that redirected it there.

  • Pass two string to Detail View from Search Array

    - by waqqas
    I am using a tableview with a search function and is populated by a plist. I want to pass 2 strings through to a DetailView. But I can only get the sting used to populate the cell to pass over. I have tried many variations but can't figure it out. Any help would be greatly appreciated. DetailView *nextLevel = [DetailView alloc]; NSString *valueString; NSString *selectedTitle; if (arraySearch == nil) { NSString *key = [arrayDataKeys objectAtIndex:indexPath.section]; NSArray *nameSection = [dictAllData objectForKey:key]; NSDictionary *dict = [nameSection objectAtIndex:indexPath.row]; valueString = [dict objectForKey:@"name"]; selectedTitle = [dict objectForKey:@"word"]; } else { valueString = [arraySearch objectAtIndex:indexPath.row]; **selectedTitle = [arraySearch objectAtIndex:indexPath.row];** //Obviously this is wrong but this is the line I need help with } nextLevel.title = valueString; nextLevel.itemname = valueString; nextLevel.itemWord = selectedTitle;

  • login using UITableView

    - by EquinoX
    How can I create a login for username/password just like in the skype application? I know it's a grouped table view.. but how can I do that? I searched the site and found the following code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; UILabel *startDtLbl = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 80, 25)]; if (indexPath.row == 0) startDtLbl.text = @"Username"; else { startDtLbl.text = @"Password"; } startDtLbl.backgroundColor = [UIColor clearColor]; [cell.contentView addSubview:startDtLbl]; UITextField *passwordTF = [[UITextField alloc] initWithFrame:CGRectMake(100, 5, 200, 35)]; passwordTF.delegate = self; if (indexPath.row == 0) passwordTF.tag = 0; else { passwordTF.tag = 1; } [cell.contentView addSubview:passwordTF]; } return cell; } When I do: NSString * username = [((UITextField*)[self.view viewWithTag:0]) text]; NSString * password = [((UITextField*)[self.view viewWithTag:1]) text]; it gives me this error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView text]: unrecognized selector sent to instance 0x6c3c600 Why is this?

  • what is the wrong with this spec and controller code?

    - by user1609468
    I'm trying to test an existing rails project with rspec. And I want to test a controller but getting an error which I can't solve :S Here is the my spec code ; require 'spec_helper' describe BriefNotesController do before(:all) do @customer=Factory(:customer) @project=Factory(:project_started, :owner => @customer) end context 'get :new' do it 'should redirect to login page for not signed in users' do get :new, :project_id => @project.id response.should redirect_to("/kullanici-girisi") end it 'should be success and render new brief note page for project owner' do sign_in @customer get :new, :project_id => @project.id response.should be_success end end end Here is the my controller code ; class BriefNotesController < ApplicationController before_filter :authenticate_user! before_filter :find_project def new @brief_note = @project.brief_notes.new end def create @brief_note = @project.brief_notes.build(params[:brief_note]) if @brief_note.save redirect_to brief_project_path(@project) else render :action => :new end end private def find_project @project = current_user.projects.find_by_cached_slug([params[:project_id]]) end end I think current_user.projects.find_by_cached_slug method don't work. So this is the error; Failures: 1) BriefNotesController get :new should be success and render new brief note page for project owner Failure/Error: get :new, :project_id => @project.id NoMethodError: undefined method `brief_notes' for nil:NilClass # ./app/controllers/brief_notes_controller.rb:6:in `new' # ./spec/controllers/brief_notes_controller_spec.rb:19:in `block (3 levels) in <top (required)>'

  • Why isn't my leak detected by Xcode Intrumensts?

    - by Arlaharen
    I am trying to analyze some code of mine, looking for memory leaks. My problem is that some of my objects are leaking (at least as far as I can see), but the Leaks tool doesn't detect the leaks. My guess is that some iPhone OS object still holds pointers to my leaked objects. The objects I am talking about are subclasses of UIViewController that I use like this: MyController *controller = [[MyController alloc] initWithNibName:@"MyController" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; When these objects are no longer needed I do: [self.navigationController popViewControllerAnimated:YES]; Without a [controller release] call right now. Now when I look at what objects that gets created I see a lot of MyController instances that never gets destroyed. To me these are memory leaks, but to the Leaks tool they are not. Can someone here tell me if there is some way Instruments can tell me what objects are pointing to my MyController instances and thereby making them not count as memory leaks? Or better yet, tell me why these leaks are not detecetd.
