  • Get String Instead of Source - Xcode Cocoa

    - by Kevin
    Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just read the hello, and not the html source.. I was assuming that it was the encoding when reading the website, but I might be possibly wrong.. I would greatly appreciate it if someone could give me a reasonable answer.. Best Regards, Kevin

  • How to reset all the values after completion of the game, before starting it again ?

    - by srikanth rongali
    I have writing a small shooting game in cocos2d. Winning the game is to eliminate all the 10 enemies. After that end screen comes showing 'You Won' and 'Play Again'. If I go for 'Play Again' option the game is starting from where I need. But, the problem is that the game is continuing from previously ended state. I mean it is not starting from enemy 1 again instead it is just showing the end of 10 enemy. I think I have to reset all the values before pushing the scene. But should I reset all the values I have used or there is any other way ? Thank You.

  • How to parse XML with special characters?

    - by Snooze
    Whenever I try to parse XML with special characters such as o or ???? I get an error. The xml documents claims to use UTF-8 encoding but that does not seem to be the case. Here is what the troublesome text looks like when I view the XML in Firefox: Bleach: The Diamond Dust Rebellion - MÅ? Hitotsu no HyÅ?rinmaru; Bleach - The DiamondDust Rebellion - Mou Hitotsu no Hyourinmaru On the actual website, Å? is actually the character o. <br /> One day, Doraemon and his friends meet Professor Mangetsu (æº?æ??å??ç??, Professor Mangetsu?), who studies magic and magical beings such as goblins, and his daughter Miyoko (ç¾?å¤?å­?, Miyoko?), and are warned of the dangerous approximation of the &quot;star of the Underworld&quot; to the Earth&#039;s orbit.<br /> <br /> And once again, on the actual website, those characters appear as ???? and ???. The actual XML file is formatted properly other than those special characters, which certainly do not appear to be using the UTF-8 encoding. Is there a way to get NSXML to parse these XML files?

  • Android Bottombar with two buttons having different backgrounds and a common background for two butt

    - by cppdev
    Hi, I have a linear layout in my main.xml which has a listview. Now I want to create a bottom bar below listview. Bottombar has a background image and two buttons with their individual background images. I want to put these two buttons on common background image. I have read that this can be achieved using FrameLayout. But since I am using LinearLayout as base layout in my main.xml, is there any way to this design using linearlayout ?

    - by monish
    Hi friends, I got an another problem in my application and I am wasting so much of time on that. Does pls anyone can help with this problem. Actually I had an Event and I should give rating for that event for that I wrote the code as: In CellForRowAtIndexPath......I had the code as: - (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MasterViewIdentifier"];

  • Most cost effective way to target multiple mobile platforms

    - by niidto
    Hi I have been given the tasks of speccing a mobile application, which will need to run on approx. 1000 devices. These devices already exist, and consist of iPhones, BlackBerrys, Androids, Windows Mobile and Netbooks. The application will have simple reporting capability, and a collection of forms. Anyway, the obvious solution would be to develop some browser based solution, although given the occasionally connected nature of the devices, there's a potential for data to get lost / not saved. So instead of creating a complex application for each platform, I was thinking we could build what is effectively a form generator, with basic offline storage capability (text files), designed to run on each device, and have the device generate a form, based on for example an XML file that it could request from a server somewhere, resulting in minimal specialist development costs, and the ability to run most of the logic from the server end, with the devices being dumb clients that render forms and upload the data when there is an available connection. Anyway, my question summarised is, how have you made the decision on supporting multiple devices for your application. Is this always an unavoidable problem, and you just have to make the call to support 1 or 2, or pay for developers to write code for each platform, or alternatively supply pre-installed devices to the company? Many thanks James

  • Core Data confusion: fetch without tableview.

    - by Mr. McPepperNuts
    I have completed and reproduced Core Data tutorials using a tableview to display contents. However, I want to access an Entity through a fetch on a view without a tableview. I used the following fetch code, but the count returned is always 0. The data exists when the database is opened using SQLite tools. NSManagedObject *entryObj; XYZDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; NSManagedObjectContext *managedObjectContext = appDelegate.managedObjectContext; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Quote" inManagedObjectContext:managedObjectContext]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"id" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [request setEntity: entity]; NSArray *results = [managedObjectContext executeFetchRequest:request error:nil]; if (results == nil) { NSLog(@"No results found"); entryObj = nil; }else { NSLog(@"results %d", [results count]); } [request release]; [sortDescriptors release]; count returned is always 0; it should be 5. Can anyone point me to a reference or tutorial regarding creating a controller not to be used with a tableview.

  • Why Is my UISlider Thumb Image Being Shown Multiple Times and Not Disappearing As They Should?

    - by Gorgando
    This slider is possessed: When I move the slider thumb left or right, it leaves the original image there (creating an extra image). This doesn't happen every time and the only consistency i've noticed is that it's inconsistent. When the table is in "Editing mode" it is more likely to create a duplicate thumb image, but it also does so in regular mode. This is the code that I use to create the slider: CGRect frame = CGRectMake(20, 42.0, 280.0, 22); self.slider = [[UISlider alloc] initWithFrame:frame]; [self.slider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged]; self.slider.continuous = YES; self.slider.minimumValue = 0.0; self.slider.maximumValue = 5.0; self.slider.value = 0.0; [sliderCell addSubview:self.slider]; Appreciate any thoughts you might have!

  • How we can perform Action on Sequence UIButtons?

    - by Prince Shazad
    As My Screen shot show that i am working on word matching game.In this game i assign my words to different UIButtons in Specific sequence on different loctions(my red arrow shows this sequence)and of rest UIButtons i assign a one of random character(A-Z).when i Click on any UIButtons its title will be assign to UILabel which is in Fornt of Current Section:i campare this UILabel text to below UILabels text which is in fornt of timer.when it match to any of my UILabels its will be deleted.i implement all this process already. But my problem is that which is show by black lines.if the player find the first word which is "DOG". he click the Two UIButtons in Sequence,but not press the Third one in Sequence.(as show by black line).so here i want that when player press the any UIButtons which is not in Sequence then remove the previous text(which is "DO") of UILabel and now the Text of UILabel is only "G" . Here is my code to get the UIButtons titles and assign it UILabel. - (void)aMethod:(id)sender { UIButton *button = (UIButton *)sender; NSString *get = (NSString *)[[button titleLabel] text]; NSString *origText = mainlabel.text; mainlabel.text = [origText stringByAppendingString:get]; if ([mainlabel.text length ]== 3) { if([mainlabel.text isEqualToString: a]){ lbl.text=@"Right"; [btn1 removeFromSuperview]; score=score+10; lblscore.text=[NSString stringWithFormat:@"%d",score]; words=words-1; lblwords.text=[NSString stringWithFormat:@"%d",words]; mainlabel.text=@""; a=@"tbbb"; } else if([mainlabel.text isEqualToString: c]){ lbl.text=@"Right"; [btn2 removeFromSuperview]; score=score+10; lblscore.text=[NSString stringWithFormat:@"%d",score]; words=words-1; lblwords.text=[NSString stringWithFormat:@"%d",words]; mainlabel.text=@""; c=@"yyyy"; } else if([mainlabel.text isEqualToString: d]){ lbl.text=@"Right"; [btn3 removeFromSuperview]; score=score+10; lblscore.text=[NSString stringWithFormat:@"%d",score]; words=words-1; lblwords.text=[NSString stringWithFormat:@"%d",words]; mainlabel.text=@""; d=@"yyyy"; } else { lbl.text=@"Wrong"; mainlabel.text=@""; } }} Thanx in advance

  • Objective-C method not being called

    - by Matt S.
    It's either because of the fact I'm tired or because I'm doing it wrong, but for some reason I can't get it to call a method. Here's what I'm trying to call: -(void)newHighScore:(int)d Which right now just does an NSLog saying "yea I'm working!" I'm calling it like this: [highscore newHighScore:score]; highscore is what I called the HighScore class in the .h, and score is an int with the score.

  • to-many Core Data fetch request behaves oddly with a new store

    - by Giao
    I have two entities, Department and Person. Department has a to-many relationship to Person. The Person entity has a hireDate property. I'm using the predicate "count(person) = 0 OR none person.hireDate %@" to find Departments without any Persons in them or Departments that haven't hired anyone since a recent date. When the app first starts up (new user experience) and Departments are inserted and no Person have been inserted, the fetch request with this predicate returns nothing. However, if I create insert a new Person entity and delete it, then save the store, the fetch request will return all the Departments. I've found a work around where, I just insert a new Person and delete it, then save the store, the fetch request as I expected it to work. I've found that inserting a new Person and deleting it without saving will not correct the problem. Is this a bug with Core Data or is this a bug with how I've designed my app?

  • Navigation Items in Navigation Bar are not appearing?

    - by Sheehan Alam
    I am displaying a UITableViewController inside of a UITabBarController that is being presented modally: -(IBAction)arButtonClicked:(id)sender{ ARViewController* arViewController = [[[ARViewController alloc] initWithNibName:@"ARViewController" bundle:nil]autorelease]; LeaderBoardTableViewController* lbViewController = [[[LeaderBoardTableViewController alloc] initWithNibName:@"LeaderBoardTableViewController" bundle:nil]autorelease]; lbViewController.title = @"Leaderboard"; arTabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:nil]; arTabBarController.viewControllers = [NSArray arrayWithObjects:arViewController, lbViewController, nil]; arTabBarController.selectedViewController = arViewController; [self presentModalViewController:arTabBarController animated:YES]; } In my viewDidLoad for arViewController method I am setting the navigation items: - (void)viewDidLoad { [super viewDidLoad]; // Uncomment the following line to preserve selection between presentations. self.clearsSelectionOnViewWillAppear = NO; self.title = @"AR"; leaderBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemOrganize target:self action:@selector(leaderBoardButtonClicked:)]; self.navigationItem.rightBarButtonItem = leaderBoardButton; } My navigation bar doesn't appear when it is inside of the UITabBarController, but when I push the view itself I am able to see it.

  • WebKitErrorDomain error 101

    The following code produces and error of: WebKitErrorDomain error 101 code: -(Void) searchBarSearchButtonClicked: (UISearchBar *) activeSearchBar { NSString * query = [searchBar.text stringByReplacingOccurrencesOfString: @ "" withString: @ "+"]; NSURL * url = [NSURL URLWithString: [NSString stringWithFormat: @ "http://http://www.google.com/search?q =%, query]]; NSURLRequest * requestObj = [NSURLRequest requestWithURL: url]; [Home loadRequest: requestObj]; } -(Void) loadView { [Super loadView]; CGRect bounds = [[UIScreen mainScreen] applicationFrame]; searchBar = [[UISearchBar alloc] initWithFrame: CGRectMake (0.0, 0.0, bounds.size.width, 48.0)]; searchBar.delegate = self; [Self.view addSubview: searchBar]; } I don't speak english and rely on a translator.

  • Properly maintain sorted state of Array/Set

    - by Jeff
    I'm trying to get data out of my MOC and then create some new objects based on those objects, and put it all back together, while keeping my sort state. The securities come out of the MOC in proper order. And everything seems to be fine until I do the assignment to the game at the bottom from setWithArray. The documentation says that setWithArray removed the duplicate objects, if there are any. I'm wonder if that's messing up my data, but I don't see a good alternative. The data is ultimately being pulled out into a UITableView. When I add items to the game manually, then they stay sorted, so I don't think the breaking of the sort is beyond the scope of what I've included here. NSError *error; NSArray *allTheSecurities = [managedObjectContext executeFetchRequest:request error:&error]; if (allTheSecurities == nil) { // Handle the error. } [request release]; /**/ NSLog( @"Enumerate..." ); NSEnumerator *enumerator = [allTheSecurities objectEnumerator]; id anObject; NSMutableArray *portfolioStocks = [[NSMutableArray alloc] init]; while (anObject = [enumerator nextObject]) { NSLog( @"Iteration... %@", [anObject name] ); NSLog( @"Build a stock..." ); PortfolioStocks *this_stock = (PortfolioStocks *)[NSEntityDescription insertNewObjectForEntityForName:@"PortfolioStocks" inManagedObjectContext:context]; NSLog( @"Set a value..." ); [this_stock setSecurity:(Security *)anObject]; [this_stock setQuantity:[NSNumber numberWithInt:0]]; NSLog( @"Add to portfolioStocks..." ); [portfolioStocks addObject:this_stock]; } //Sorted properly up to here! NSLog( @"Add to portfolio..." ); [game setPortfolio:[NSSet setWithArray:portfolioStocks]]; // <-- This is where it's not sorted anymore.

  • Why call autorelease for iVar definition in init method?

    - by iFloh
    Hi, I just familiarise myself with the CLLocationManager and found several sample class definitions that contain the following init method: - (id) init { self = [super init]; if (self != nil) { self.locationManager = [[[CLLocationManager alloc] init] autorelease]; self.locationManager.delegate = self; } return self; } - (void)dealloc { [self.locationManager release]; [super dealloc]; } I don't understand why the iVar would be autoreleased. Does this not mean it is deallocated at the end of the init method? I am also puzzled to see the same sample codes have the iVar release in the dealloc method. Any thoughts? '

  • 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. :(

  • Loading different portrait/landscape UIViews

    - by Tronic
    Hi, I have following View COntroller structure: ScrollViewController LandscapeViewController PortraitViewController Each with its own .nib The app starts in landscape mode where many landscape views are added to a scrollview. Each landscape view has its specific portrait view, so I have to assign like ID's to each of this views. Can you tell me, how I can load the specific portrait view for each landscape view when rotating the device? Do I have to make two scroll views? One for landscape, one for portrait? Or is it possible to just scroll through the landscape scrollview an load just one portrait view with the right content based on an ID? How could I implement that? The data comes from a property list. Thanks in advance!

  • Objective C Enumerate Sentences in a paragraph

    - by Faz Ya
    I would like to write an enumerator that would go through a paragraph of text and gives me one sentence at a time. I tried using stringEnumerate with the NSStringEnumerationBySentences but that simply looks at the periods and fails. For example, lets say I have the following text Block: "Senator John A. Boehner decided not to move forward. He also decided not to call the congress. The news reporter said though...." I would like my function to break down the above paragraph in the following sentences: Senator John A. Boehner decided not to move forward He also decided not to call the congress (No third sentence because it's a half a sentence) The String Enumerator with the sentence optionjust looks at the periods and breaks down that way which is wrong: Senator John A. Boehner decided not to move forward He also decided not to call the congress The news reporter said though.... Is there any library or function that I can call that does a better job at this? Thanks - (NSMutableString *) getOnlyFullSentencesFromTextBlock:(NSMutableString *) textBlock{ [textBlock enumerateSubstringsInRange:NSMakeRange(0, [textBlock length]) options:NSStringEnumerationBySentences | NSStringEnumerationLocalized usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) { NSLog(@"Sentence Frag:%@", substring); }]; return textBlock; }

  • Creating your own UTI for an iOS app.

    - by Kalle
    Hello all, The app I'm developing has a custom file format for its files, and I'd like to be able to use the "Open In ..." feature of iOS which lets users e.g. email each other a file and then open it directly in the app. I've gotten as far as adding the CFBundleDocumentType stuff in the Info.plist file, but the problem is the LSItemContentTypes. From what I've read, I need to provide the actual file as a UTI, rather than just saying ".myfileextension", and I can't find a lot about how to create UTI's in a iOS app. Anyone know?
