  • jQuery: Inserting li items one by one?

    - by Legend
    I wrote the following (part of a jQuery plugin) to insert a set of items from a JSON object into a <ul> element. ... query: function() { ... $.ajax({ url: fetchURL, type: 'GET', dataType: 'jsonp', timeout: 5000, error: function() { self.html("Network Error"); }, success: function(json) { //Process JSON $.each(json.results, function(i, item) { $("<li></li>") .html(mHTML) .attr('id', "div_li"+i) .attr('class', "divliclass") .prependTo("#" + "div_ul"); $(slotname + "div_li" + i).hide(); $(slotname + "div_li" + i).show("slow") } } }); } }); }, ... Doing this maybe adding the <li> items one by one theoretically but when I load the page, everything shows up instantaneously. Instead, is there an efficient way to make them appear one by one more slowly? I'll explain with a small example: If I have 3 items, this code is making all the 3 items appear instantaneously (at least to my eyes). I want something like 1 fades in, then 2 fades in, then 3 (something like a newsticker perhaps). Anyone has a suggestion?

  • Django and Google App Engine Helper not finding the ipaddr module.

    - by Phil
    I'm trying to get Django running on GAE using this tutorial. When I run python manage.py runserver I get the stacktrace below. I'm new to both django and python so I don't know what my next steps are (This is Ubuntu Jaunty btw). It seems django isn't finding the GAE module ipaddr which comes with SDK 1.3.1.

  • Testing a wide variety of computers with a small company

    - by Tom the Junglist
    Hello everyone, I work for a small dotcom which will soon be launching a reasonably-complicated Windows program. We have uncovered a number of "WTF?" type scenarios that have turned up as the program has been passed around to the various not-technical-types that we've been unable to replicate. One of the biggest problems we're facing is that of testing: there are a total of three programmers -- only one working on this particular project, me -- no testers, and a handful of assorted other staff (sales, etc). We are also geographically isolated. The "testing lab" consists of a handful of VMWare and VPC images running sort-of fresh installs of Windows XP and Vista, which runs on my personal computer. The non-technical types try to be helpful when problems arise, we have trained them on how to most effectively report problems, and the software itself sports a wide array of diagnostic features, but since they aren't computer nerds like us their reporting is only so useful, and arranging remote control sessions to dig into the guts of their computers is time-consuming. I am looking for resources that allow us to amplify our testing abilities without having to put together an actual lab and hire beta testers. My boss mentioned rental VPS services and asked me to look in to them, however they are still largely very much self-service and I was wondering if there were any better ways. How have you, or any other companies in a similar situation handled this sort of thing? EDIT: According to the lingo, our goal here is to expand our systems testing capacity via an elastic computing platform such as Amazon EC2. At this point I am not sure suggestions of beefing up our unit/integration testing are going to help very much as we are consistently hitting walls at the systems testing phase. Has anyone attempted to do this kind of software testing on a cloud-type service like EC2? Tom

  • Why do i get exc bad access in cases when object is not nil?

    - by DixieFlatline
    I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame: if (!myTableView) { NSLog(@"self.myTableView is nil"); } myTableView.frame=CGRectMake(0, 70, 320, 376); This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil. Crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x522d580c Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x352b1f7e objc_msgSend + 22 1 Foundation 0x37dc174c NSKVOPendingNotificationCreate + 216 2 Foundation 0x37dc1652 NSKeyValuePushPendingNotificationPerThread + 62 3 Foundation 0x37db3744 NSKeyValueWillChange + 408 4 Foundation 0x37d8a848 -[NSObject(NSKeyValueObserverNotification) willChangeValueForKey:] + 176 5 Foundation 0x37e0ca14 _NSSetPointValueAndNotify + 76 6 UIKit 0x312af25a -[UIScrollView(Static) _adjustContentOffsetIfNecessary] + 1890 7 UIKit 0x312cca54 -[UIScrollView setFrame:] + 548 8 UIKit 0x312cc802 -[UITableView setFrame:] + 182 9 POViO 0x000913cc -[FeedVC viewWillAppear:] (FeedVC.m:303) Dealloc is not called because it is not logged: - (void)dealloc { NSLog(@"dealloc"); }

  • iPhone SDK: How do you download video files to the Document Directory and then play them?

    - by Jessica
    I've been fooling around with code for ages on this one, I would be very grateful if someone could provide a code sample that downloaded this file from a server http://www.archive.org/download/june_high/june_high_512kb.mp4, (By the way it's not actually this file, it's just a perfect example for anyone trying to help me) and then play it from the documents directory. I know it seems lazy of me to ask this but I have tried so many different variations of NSURLConnection that it's driving me crazy. Also, if I did manage to get the video file downloaded would I be correct in assuming this code would then successfully play it: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"june_high_512kb.mp4"]; NSURL *movieURL = [NSURL fileURLWithPath:path]; self.theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [_theMovie play]; If the above code would work in playing a video file from the document directory, then I guess the only thing I would need to know is, how to download a video file from a server. Which is what seems to be my major problem. Any help is greatly appreciated.

  • Problem in print layout near page end

    - by Miraaj
    Hi all, I am facing some problem in print layout, below is the description of steps I followed and problem which I am facing: I have taken a custom view over which there are NSTextViews, NSTableViews arranged one below other. I am trying to calculate exact height of NSTextViews and NSTableViews depending upon content in them. Depending upon calculated height I am arranging them in super-custom view. Then I am printing the view, using this code : [self arrangeBriefLayoutDynamically]; // step 2nd and 3rd // setting fixed parameters for printing NSPrintInfo * printInfo = [NSPrintInfo sharedPrintInfo]; [printInfo setVerticallyCentered:NO]; [printInfo setRightMargin:12.0]; [printInfo setTopMargin:37.0]; [printInfo setLeftMargin:12.0]; [printInfo setHorizontallyCentered:YES]; [printInfo setHorizontalPagination:NSFitPagination]; [printInfo setVerticalPagination:NSAutoPagination]; [printInfo setPaperName:@"na-letter"]; [printInfo setOrientation:NSPortraitOrientation]; PMSetScale([printInfo PMPageFormat], 100.0); [NSPrintInfo setSharedPrintInfo:printInfo]; [briefCompleteView print:nil]; Problem is : when size of a table view or text view exceeds, such that it crosses the page boundary then SOMETIMES text near boundary appears improper i.e.. part of its height lies on first page and rest of it lies on second page. Click to check problem ! Can anyone suggest me some way to resolve it ? Thanks, Miraaj

  • How to remove view from window?

    - by Wayfarer
    I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view: window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; This works as expected, and shows the TargetPlayerViewController. Wonderful! What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing. To test I have a button on the view set up which triggers this method: - (IBAction)GTFOnow:(id)sender { NSLog(@"GFTO"); window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; //[self.view removeFromSuperview]; //[window makeKeyAndVisible]; } In this method the view should remove itself from the view so I can go back to the Cocos2D. How do I do this?

  • Why doesen't it work to write this NSMutableArray to a plist?

    - by Emil
    edited. Hey, I am trying to write an NSMutableArray to a plist. The compiler does not show any errors, but it does not write to the plist anyway. I have tried this on a real device too, not just the Simulator. Basically, what this code does, is that when you click the accessoryView of a UITableViewCell, it gets the indexPath pressed, edits an NSMutableArray and tries to write that NSMutableArray to a plist. It then reloads the arrays mentioned (from multiple plists) and reloads the data in a UITableView from the arrays. Code: NSIndexPath *indexPath = [table indexPathForRowAtPoint:[[[event touchesForView:sender] anyObject] locationInView:table]]; [arrayFav removeObjectAtIndex:[arrayFav indexOfObject:[NSNumber numberWithInt:[[arraySub objectAtIndex:indexPath.row] intValue]]]]; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"arrayFav.plist"]; NSLog(@"%@ - %@", rootPath, plistPath); [arrayFav writeToFile:plistPath atomically:YES]; // Reloads data into the arrays [self loadDataFromPlists]; // Reloads data in tableView from arrays [tableFarts reloadData];

  • NSThread terminating too early

    - by JustinXXVII
    I have an app that uploads to Google Spreadsheets via the GData ObjC client for Mac/iPhone. It works fine as is. I'm trying to get the upload portion on its own thread and I'm attempting to call the upload method on a new thread. Look: -(void)establishNewThreadToUpload { [NSThread detachNewThreadSelector:@selector(uploadToGoogle) toTarget:self withObject:nil]; } -(void)uploadToGoogle { NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init]; //works fine [helper setNewServiceWithName:username password:password]; //works fine [helper fetchUserSpreadsheetFeed]; //inside the helper class, fetchUserSpreadsheet feed calls ANOTHER method, which //calls ANOTHER METHOD and so on, until the object is either uploaded or fails //However, once the class gets to the end of fetchUserSpreadsheetFeed //control is passed back to this method, and [pool release]; //is called. The thread terminates and nothing ever happens. } If I forget about using a separate thread, everything works like it's supposed to. I'm new to thread programming, so if there's something I'm missing, please clue me in! Thanks!

  • tabs on web page and seo

    - by GaVrA
    I know there is a lot of js plugins to do "tabs", but also i can do it my self. Just have some elements with display:none and when you click some other element display changes to block, or something like that. Now, i have a one site i am developing, where i am giving specific users(all within one usergroup) access to edit only one page which i have created. That part is done. Now i have a request to give those users ability to edit 2 more sub pages, but since its all gonna be the same, like text with some pictures, i was thinking to put 3 textarea's so they will have 1 page where they can edit content of all those 3 pages. What i also thought was to only have one page and on it to have 3 tabs. Each tab for each possible page. When i started thinking about that the only concern was seo. How does seo works regarding elements with display:none? What jquery tabs plugin do you recommend that has the ability to access tabs via id of the element in url? I was looking at jquery ui demo but there when you get the url of one of those tabs and try to open it in new window, that tab is not opened. For example this link: http://jqueryui.com/demos/tabs/#tabs-2 It does not open tab #2... Any help is appreciated!

  • import problem with twisted.web server

    - by Carson Myers
    I'm just getting started with twisted.web, and I'm having trouble importing a Python module into a .rpy script. in C:\py\twisted\mysite.py, I have this: from twisted.web.resource import Resource from twisted.web import server class MySite(Resource): def render_GET(self, request): request.write("<!DOCTYPE html>") request.write("<html><head>") request.write("<title>Twisted Driven Site</title>") request.write("</head><body>") request.write("<h1>Twisted Driven Website</h1>") request.write("<p>Prepath: <pre>{0}</pre></p>".format(request.prepath)) request.write("</body></html>") request.finish() return server.NOT_DONE_YET and in C:\py\twisted\index.rpy, I have this: import mysite reload(mysite) resource = mysite.MySite() I ran twistd -n web --port 8888 --path C:\py\twisted in command prompt and the server started successfully. But when I requested localhost:8888 I got a (huge) stack trace originating from an ImportError: <type 'exceptions.ImportError'>: No module named mysite I can import the module from the interpreter, and if i just execute index.rpy as a python script, I don't get the import error. The documentation on this subject is a bit vague, it just says "However, it is often a better idea to define Resource subclasses in Python modules. In order for changes in modules to be visible, you must either restart the Python process, or reload the module:" (from here). Does anyone know the proper way to do this?

  • Unit test insert/update/delete

    - by Kurresmack
    Hey, I have googled this a little and didn't really find the answer I needed. I am working on a webpage in C# with MSSQL and LINQ for a customer. I want the users to be able to send messages to each other. So what I do is that I unit test this with data that actually goes into the database. The problem is that I now depend on having at least 2 users who I know the ID of. Furthermore I have to clean up after my self. This leads to rather large unit tests that test alot in one test. Lets say I would like to update a user. That would mean that I would have to ceate the user, update it, and then delete it. This a lot of assertions in one unit test and if it fails with updating i have to manually delete it. If I would do it any other way, without saving the data to DB, I would not for sure be able to know that the data was present in the database after updating etc. What is the proper way to do this without having a test that tests a lot of functuality in one test?

  • Can I compare a template variable to an integer in App Engine templates?

    - by matt b
    Using Django templates in Google App Engine (on Python), is it possible to compare a template variable to an integer in an {% if %} block? views.py: class MyHandler(webapp.RequestHandler): def get(self): foo_list = db.GqlQuery(...) ... template_values['foos'] = foo_list template_values['foo_count'] = len(foo_list) handler.response.out.write(template.render(...)) My template: {% if foo_count == 1 %} There is one foo. {% endif %} This blows up with 'if' statement improperly formatted. What I was attempting to do in my template was build a simple if/elif/else tree to be grammatically correct to be able to state #foo_count == 0: There are no foos. #foo_count == 1: There is one foo. #else: There are {{ foos|length }} foos. Browsing the Django template documents (this link provided in the GAE documentation appears to be for versions of Django far newer than what is supported on GAE), it appears as if I can only actually use boolean operators (if in fact boolean operators are supported in this older version of Django) with strings or other template variables. Is it not possible to compare variables to integers or non-strings with Django templates? I'm sure there is an easy way to workaround this - built up the message string on the Python side rather than within the template - but this seems like such a simple operation you ought to be able to handle in a template. It sounds like I should be switching to a more advanced templating engine, but as I am new to Django (templates or any part of it), I'd just like some confirmation first.

  • UITextField inside of UITableViewCell will not activate on iPad but works on iPhone

    - by cfihelp
    I have a UITextField inside a UITableViewCell. It will not activate on the iPad (but it works fine on the iPhone) no matter what I try. Tapping on it and telling it to become the firstResponder both fail. The odd thing is that if I take the exact same code and move it to another view controller in my app it executes just fine. This makes it seem as if there is likely a problem in the parent UITableViewController but I can't find anything obvious. I'm hoping that someone out there has experienced a similar problem and can point me in the right direction. Below is the sample code that works fine when I move it to a new project or put it in a new view controller launched immediately by my app delegate: // Customize the appearance of table view cells. - (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]; } if (indexPath.row == 0) { UITextField *nameText = [[UITextField alloc] initWithFrame:CGRectMake(5, 5, cell.contentView.frame.size.width, cell.contentView.frame.size.height)]; nameText.delegate = self; nameText.backgroundColor = [UIColor redColor]; [cell.contentView addSubview:nameText]; [nameText becomeFirstResponder]; [nameText release]; } // Configure the cell... return cell; } Help!

  • Help me understand entity framework 4 caching for lazy loading

    - by Chris
    I am getting some unexpected behaviour with entity framework 4.0 and I am hoping someone can help me understand this. I am using the northwind database for the purposes of this question. I am also using the default code generator (not poco or self tracking). I am expecting that anytime I query the context for the framework to only make a round trip if I have not already fetched those objects. I do get this behaviour if I turn off lazy loading. Currently in my application I am breifly turning on lazy loading and then turning it back off so I can get the desired behaviour. That pretty much sucks, so please help. Here is a good code example that can demonstrate my problem. Public Sub ManyRoundTrips() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() 'makes unnessesary round trip to the database, I just loaded the employees' MessageBox.Show(context.Employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) context.Orders.Execute(System.Data.Objects.MergeOption.AppendOnly) For Each emp As Employee In employees 'makes unnessesary trip to database every time despite orders being pre loaded.' Dim i As Integer = emp.Orders.Count Next End Sub Public Sub OneRoundTrip() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Include("Orders").Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() MessageBox.Show(employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) For Each emp As Employee In employees Dim i As Integer = emp.Orders.Count Next End Sub Why is the first block of code making unnessesary round trips?

  • PHP: Echo function output in function-line, not line of function call

    - by Brill
    I have a problem with my self-coded template system. The content is inserted by Include(). Now I need to add a meta redirect to one page. I know, meta redirect is not the safest way, but I need it because of it's delay possibility. Now i'm looking for a way to influence the wrapping page (template) by the wrapped page (content). So I thought a function can do this job. <?php function test($testvar){ echo $testvar;} ?> <hr /> <?php test("testtext"); ?> Of course the text echos in the line of the function call, not in the function line. Is there a way to make the function echo in the line of the function itself? In this case above the horizontal rule, not below? Of course every other best pratice for this "template problem" ist welcome! THX

  • Objective-C Implementation Pointers

    - by Dwaine Bailey
    Hi, I am currently writing an XML parser that parses a lot of data, with a lot of different nodes (the XML isn't designed by me, and I have no control over the content...) Anyway, it currently takes an unacceptably long time to download and read in (about 13 seconds) and so I'm looking for ways to increase the efficiency of the read. I've written a function to create hash values, so that the program no longer has to do a lot of string comparison (just NSUInteger comparison), but this still isn't reducing the complexity of the read in... So I thought maybe I could create an array of IMPs so that, I could then go something like: for(int i = 0; i < [hashValues count]; i ++) { if(currHash == [[hashValues objectAtIndex:i] unsignedIntValue]) { [impArray objectAtIndex:i]; } } Or something like that. The only problem is that I don't know how to actually make the call to the IMP function? I've read that I perform the selector that an IMP defines by going IMP tImp = [impArray objectAtIndex:i]; tImp(self, @selector(methodName)); But, if I need to know the name of the selector anyway, what's the point? Can anybody help me out with what I want to do? Or even just some more ways to increase the efficiency of the parser...

  • Subclass of UIView with Xib file.

    - by rdesign
    Hey guys, Although I've searched the Board and used google, I didn't get any useful results. I've trying to make a subclass of UIView loading its view from a xib file. My approach is the following: 1. Creating a subclass (named mySubclass): @interface mySubclass : UIView { } @end Creating a view through: Add New File... User Interface View XIB Connecting the Xib and the subclass: In IB select the View and set the class to mySubclass. In my viewController I make an instance of my new subclass and add to my view. -(void)viewDidLoad { mySubclassIns = [[mySubclass alloc] initWithFrame:CGRectMake(0, 0, 320, 460)]; [self.view addSubview:mySubclassIns]; [super viewDidLoad]; } Result: Noting shows up in my App :( If I don't set it up programmatically but rather with IB it doesn't work either. (Am I setting it up right when choosing a view in IB and set the class to myClass?) I would be really thankful for your help! Thanks in advance.

  • What is Ruby's analog to Python Metaclasses?

    - by Sean Copenhaver
    Python has the idea of metaclasses that, if I understand correctly, allow you to modify an object of a class at the moment of construction. You are not modifying the class, but instead the object that is to be created then initialized. Python (at least as of 3.0 I believe) also has the idea of class decorators. Again if I understand correctly, class decorators allow the modifying of the class definition at the moment it is being declared. Now I believe there is an equivalent feature or features to the class decorator in Ruby, but I'm currently unaware of something equivalent to metaclasses. I'm sure you can easily pump any Ruby object through some functions and do what you will to it, but is there a feature in the language that sets that up like metaclasses do? So again, Does Ruby have something similar to Python's metaclasses? Edit I was off on the metaclasses for Python. A metaclass and a class decorator do very similar things it appears. They both modify the class when it is defined but in different manners. Hopefully a Python guru will come in and explain better on these features in Python. But a class or the parent of a class can implement a __new__(cls[,..]) function that does customize the construction of the object before it is initialized with __init__(self[,..]).

  • Uploading UIImage to server using UIImageJPEGRepresentation

    - by Thomas Joos
    hi all, I'm writing an app which uploads a UIImage to my server. This works perfect, as I see the pictures being added. I use the UIImageJPEGRepresentation for the image data and configure an NSMutableRequest. ( setting url, http method, boundary, content types and parameters ) I want to display an UIAlertView when the file is being uploaded and I wrote this code: //now lets make the connection to the web NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"return info: %@", returnString); if (returnString == @"OK") { NSLog(@"you are snapped!"); // Show message image successfully saved UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"You are snapped!" message:@"BBC snapped your picture and will send it to your email adress!" delegate:self cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [alert show]; [alert release]; } [returnString release]; The returnString outputs: 2010-04-22 09:49:56.226 bbc_iwh_v1[558:207] return info: OK The problem is that my if statements does not say returnstring == @"OK" as I don't get the AlertView. How should I check this returnstring value?

  • Can a web app in xul:iframe access functions from its parent XUL file?

    - by oskar
    I want to deploy a web app as a self-contained program using XULRunner. I'm simply loading it in a xul:iframe tag within the main XUL file. It works, but I want the web app to have access to XUL components, specifically nsiFilePicker. My tentative solution is to run the xul:iframe with escalated privileges (by omitting the "type" attribute), wait for the xul:iframe to load, then define a javascript function that the web app will then call. <window id="main" width="800" height="600" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <iframe id="contentview" src="web/index.html" flex="1"/> <script> //listen for XUL window to load window.addEventListener("load",Listen,false); function Listen() { var frame = document.getElementById("contentview"); frame.addEventListener("DOMContentLoaded", DomLoadedEventHandler, true); } //listen for iframe to load function DomLoadedEventHandler() { //set function in iframe called testMe() var frame = document.getElementById("contentview"); frame.contentWindow.testMe = function () { alert("This is a test"); }; } </script> </window> ...and then in the index.html file of the web app... <script> testMe(); </script> This doesn't seem to work. Does anyone have any suggestions?

    - by user187532
    Hello friends, I am trying to implement 'scrollview' effect in 'Tabbar' which has 'TabItems'. I found that the good example is from 'facebook' open source 'TTCatlog' project 'Tabs' section. So i included all the source from it to my project and trying to build it. I have followed the following links to go ahead on this: http://stackoverflow.com/questions/822792/how-to-create-a-horizontal-scrolling-view-on-iphone source: http://github.com/facebook/three20/tree/master/samples/ My calling code is like below: _tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(10, 68, 300, 28)]; _tabBar1.tabItems = [NSArray arrayWithObjects: [[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease], [[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease], nil]; [self.navigationController.view addSubview:_tabBar1]; My project folder as like below: ..../iphone/MyProgram/MyProgram.xcodeproj ..../iphone/Three20/src/Three20.... In my project settings for header search path, I have ../Three20/src But when i try to build it, it throws the following error: "objc_class_name_TTTabStrip symbol not found" "objc_class_name_TTTabItem symbol not found" I see there, all these files (.h and .m) are availbale there. Could someone please help what's wrong there and how do i get rid of this issue and continue working with it?
