  • iOs receivedData from NSURLConnection is nil

    - by yhl
    I was wondering if anyone could point out why I'm not able to capture a web reply. My NSLog shows that my [NSMutableData receivedData] has a length of 0 the entire run of the connection. The script that I hit when I click my login button returns a string. My NSLog result is pasted below, and after that I've pasted both the .h and .m files that I have.

  • Most Efficient way to deal with multiple CCSprites?

    - by nardsurfer
    I have four different types of objects within my environment(box2d), each type of object having multiple instances of itself, and would like to find the most efficient way to deal with adding and manipulating all the CCSprites. The sprites are all from different files, so would it be best to create each sprite and add it to a data structure (NSMutableArray) or would I use a CCSpriteBatchNode even though each CCSprite file is different (for each type of object)? Thanks. @interface LevelScene : CCLayer { b2World* world; GLESDebugDraw *m_debugDraw; CCSpriteBatchNode *ballBatch; CCSpriteBatchNode *blockBatch; CCSpriteBatchNode *springBatch; CCSprite *goal; } +(id) scene; // adds a new sprite at a given coordinate -(void) addNewBallWithCoords:(CGPoint)p; // loads the objects (blocks, springs, and the goal), returns the Level Object -(Level) loadLevel:(int)level; @end or using NSMutableArray objects within the Level object... @interface zLevel : zThing { NSMutableArray *springs; NSMutableArray *blocks; NSMutableArray *balls; zGoal *goal; int levelNumber; } @property(nonatomic,retain)NSMutableArray *springs; @property(nonatomic,retain)NSMutableArray *blocks; @property(nonatomic,retain)NSMutableArray *balls; @property(nonatomic,retain)zGoal *goal; @property(nonatomic,assign)int levelNumber; -(void)initWithLevel:(int)level; -(void)loadLevelThings; @end

  • Retrieving Data in A NSTableView

    - by Heisennberg
    I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

  • iPhone: Get value in multi-dimentional array

    - by Nic Hubbard
    I have an array that is many levels deep and I am wondering what is the best way to get one of the child element values that is deep in my array. I assume I need to use a recursive method, but what is the best way to do this? Or is there a faster way to do this? The array comes from an XML Parser that I am using which builds everything into an array like this (using NSLog to show the structure): { children = ( { children = ( { children = ( { children = ( ); data = 12; element = AssetID; } ); data = ""; element = "ns1:GetUserIdByUsernameResponse"; } ); data = ""; element = "SOAP-ENV:Body"; } ); data = ""; element = "SOAP-ENV:Envelope"; } What I would like to get at is the AssetID data, which in this case is 12.

  • Image Size for Animation!

    - by taimur-hamza
    Hi Everybody, I m new to iphone app development and i need some help. I have a list of 30 images that i have to animate and display with 0.1 second interval. I put all the images in an Array using this imageletter.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"], ...... ,nil] And then animate it using these statements, [imageletter setAnimationDuration:16]; [imageletter startAnimating]; [NSTimer scheduledTimerWithTimeInterval:mytime target:self selector:@selector(StopAfterCertainTime) userInfo:nil repeats:NO]; Now the problem is that the size of each image is 8kb , it runs fine on iphone simulator but crashes on device. When i used 30 other images of 4kb each it runs fine both on simulator and device. Can anybody tell me what is the ideal size for such kind of task. Thanks

  • MKPinAnnotationView - hard to drag

    - by James Zaghini
    I have a MKPinAnnotationView that the user can drag around the map. It is very difficult for a user to drag the pin. I've tried increasing the frame size and also using a giant custom image. But nothing seems to actually change the hit area for the drag to be larger than default. Consequently, I have to attempt to tap/drag about ten times before anything happens. MKPinAnnotationView *annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"bluedot"] autorelease]; UIImage *image = [UIImage imageNamed:@"blue_dot.png"]; annView.image = image; annView.draggable = YES; annView.selected = YES; return annView; What am I missing here?

  • dismissing uiwebview

    - by chimgrrl
    Ok, I really spend 2 days on this and it has gotten me stumped. From my main UIViewController I called a WebViewController which is a UIViewController with a UIWebView inside: UOLCategoriesWebViewController *ucwvcontroller = [[UOLCategoriesWebViewController alloc] initWithNibName:@"UOLCategoriesWebViewController" bundle:nil]; [self presentModalViewController:ucwvcontroller animated:YES]; [ucwvcontroller release]; Inside the UOLCategoriesWebViewController I've call the delegate method shouldStartLoadWithRequest where when the user clicks on a particular type of link it parses out the params and return back to the main UIViewController (or at least that's what I want it to do): - (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType { BOOL continueOrExit = YES; NSURL *url = request.URL; NSString *urlString = [url relativeString]; NSString *urlParams = [url query]; NSArray *urlParamArr = [urlParams componentsSeparatedByString:@"&"]; NSLog(@"the url is: %@",urlString); //NSLog(@"the params are: %@,%@",[urlParamArr objectAtIndex:0],[urlParamArr objectAtIndex:1]); //BOOL endTrain1 = [[urlParamArr objectAtIndex:1] hasPrefix:@"subCatValue"]; //BOOL endTrain2 = ([urlParamArr objectAtIndex:1 //NSLog(@"Number of elements: %@",[urlParamArr count]); if (navigationType == UIWebViewNavigationTypeLinkClicked) { //NSLog(@"Enter into His glory"); if ([urlString hasSuffix:@"categories_list.php"]) { //NSLog(@"2nd Heaven"); continueOrExit = YES; }else if ([[urlParamArr objectAtIndex:1] hasPrefix:@"subCatValue"]) { continueOrExit = NO; NSLog(@"end of the train"); NSArray *firstParamStringArr = [[urlParamArr objectAtIndex:0] componentsSeparatedByString:@"="]; NSArray *secondParamStringArr = [[urlParamArr objectAtIndex:1] componentsSeparatedByString:@"="]; NSString *catSelected = [firstParamStringArr objectAtIndex:1]; NSString *subCatSelected = [secondParamStringArr objectAtIndex:1]; //go back to native app [self goBackToMain:catSelected andSubCat:subCatSelected]; } } return continueOrExit; } Actually in the above function where I am calling the goBackToMain method I want it to call the delegate method and return to the mainviewcontroller. Unfortunately after executing that goBackToMain method it goes back to this method and continue to return continueOrExit. Is there anyway to make it truly exit without returning anything? I've tried putting in multiple returns to no avail. Or can I in the html page pass some javascript to directly call this method so that I don't have to go through this delegate method? Thanks for the help in advance!

  • Using [self method] or @selector(method)?

    Can anyone enlighten me as to the differences between the two statements below. [self playButtonSound]; AND: [self performSelector:@selector(playButtonSound)]; I am just asking as I had some old code that used @selector, now with a little more knowledge I can't think why I did not use [self playButtonSound] instead, they both seem to do the same as written here. gary

  • Animation with CGPoint in for loop

    - by user1066524
    I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

  • How to set UITableViewCell highlighted image

    - by SmartTree
    I want to launch a method every time when user just highlights a cell (doesn't select it) in UITableView. Could you tell me please, how is it possible to do this ? I want to do it because I have a custom cell with a pictures on it and I want to change pictures every time when user highlights the cell. UPD: By highlight I mean that user just highlights a cell and don't release the finger from it. By select I mean when didSelectRowAtIndexPath is being launched (so the user releases the finger from the cell after he presses on it)
