  • Hiding iAds when loading?

    - by Jesper Mansa
    I'm trying to make an ios app with an iAd in the bottom but lifted a little bit. It actually woks ok but when the iAd is loading it shows an white area just below where the iAd should be. When its done loading the iAd jumps up in the right position. I think normaly the button is loaded outside the screen and nthen pop ups when done but because mine add is liftet a little I can see the loading area... Is there a way to make the iAd load in the sides instead and then popin from the side? Here is what I have so far: frame.origin.x = ( _screenWidth - frame.size.width ) / 2; if( calculateForBannerOnBottom ) frame.origin.y = _screenHeight - (frame.size.height/1.2); else frame.origin.y = -_adView.frame.size.height+(frame.size.height/2.4); Hoping 4 help and thanks in advance :-)

  • Cell contents changing after I select rows present outside its height?

    - by wolverine
    I have set the size of the tableView that I show as the popoverController as 4*rowheight. And I am using 12cells in the tableView. Each cell contains an image and a label. I can see all the cells by scrolling. Upto 5th cell its ok. After th2 5th cell, the label and the image that I am using in the first four cells are being repeated for the remaining cells. And If I select the cell, the result is accurately shown. But when I again take the tableView, the image and labels are not accurate even for the first 5 cells. All are changed but the selection is giving the correct result. Did anyone got the idea what the problem is??

My problem is all three sprite1, sprite2, remaining screen should have independent touches. But my program is taking all the touches as same. How can I make them as what I needed ? Thank You.

  • How to fetch managed objects sorted by calculated value

    - by Marcin Zbijowski
    Hello, I'm working on the app that uses CoreData. There is location entity that holds latitude and longitude values. I'd like to fetch those entities sorted by distance to the user's location. I tried to set sort descriptor to distance formula sqrt ((x1 - x2)^2 + (y1 - y2)^2) but it fails with exception "... keypath ... not found in entity". NSString *distanceFormula = [NSString stringWithFormat:@"sqrt(((latitude - %f) * (latitude - %f)) + ((longitude - %f) * (longitude - %f)))", location.coordinate.latitude, location.coordinate.latitude, location.coordinate.longitude, location.coordinate.longitude]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:distanceFormula ascending:YES]; [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]]; NSError *error; NSArray *result = [[self managedObjectContext] executeFetchRequest:fetchRequest error:&error]; I'd like to fetch already sorted objects rather then fetch them all and then sort in the code. Any tips appreciated.

  • UIView surface Detection

    - by Sanjay Darshil
    In my code I crated two UIView View1 and View2 out of which View2 rotates on finger touch using CGAffineTransform and View1 is drawn like Arrow shaped (triangle) using CGContext. The View1 is steady view (fixed) which Points (shown directed Up) to the Surface of View2 , So I want to detect the View2 surface points when it stopped rotation and appears in front of the view1. How can I made this possible to detect the UIView Surface when it appears in front of another UIView?

  • inserting time delay with cocos2d

    - by KDaker
    I am trying to add several labels that appear sequentially with a time delay between each. The labels will display either 0 or 1 and the value is calculated randomly. I am running the following code: for (int i = 0; i < 6; i++) { NSString *cowryString; int prob = arc4random()%10; if (prob > 4) { count++; cowryString = @"1"; } else { cowryString = @"0"; } [self runAction:[CCSequence actions:[CCDelayTime actionWithDuration:0.2] ,[CCCallFuncND actionWithTarget:self selector:@selector(cowryAppearWithString:data:) data:cowryString], nil]]; } the method that makes the labels appear is this: -(void)cowryAppearWithString:(id)sender data:(NSString *)string { CCLabelTTF *clabel = [CCLabelTTF labelWithString:string fontName:@"arial" fontSize:70]; CGSize screenSize = [[CCDirector sharedDirector] winSize]; clabel.position = ccp(200.0+([cowries count]*50),screenSize.height/2); id fadeIn = [CCFadeIn actionWithDuration:0.5]; [clabel runAction:fadeIn]; [cowries addObject:clabel]; [self addChild:clabel]; } The problem with this code is that all the labels appear at the same moment with the same delay. I understand that if i use [CCDelayTime actionWithDuration:0.2*i] the code will work. But the problem is that i might also need to iterate this entire for loop and have the labels appear again after they have appeared the first time. how is it possible to have actions appear with delay and the actions dont always follow the same order or iterations???

  • Detect double-tap on UISlider?

    - by Randy
    I can detect single/double-taps in specific views with: NSSet *myTouches = [event touchesForView:mySpecificView.view]; but I want to detect a double-tap on the button of a slider and can't find any reference to it. Is there a replacement for "touchesForView:" where I can enter the name of my slider? usage: I have three sliders with their default value being directly in the center of the slider. Once the position of the slider has changed, I want a quick way to individually reset each slider to its default position. I currently have each slider's containing view set to respond to a double-tap, updating each slider. It works fine, but doesn't seem natural. ie.I can't double-tap on the slider itself because the slider intercepts the taps and doesn't pass them on to the surrounding view. thanks in advance

  • How to programaticly access min and Max values defined in a core-data model designed with XCode ?

    - by Xav
    I was expecting to find that in the NSAttributeDescription class, but only the default value is there. Behind the scene I tought a validationPredicate was created but trying to reach it using NSDictionary* dico= [[myManagedObject entity] propertiesByName]; NSAttributeDescription* attributeDescription=[dico objectForKey:attributeKey]; for (NSString* string in [attributeDescription validationWarnings]) just get me nowhere, no validationWarnings, no validationPredicates... any thoughts on this ? Edit1: It seems that getting the entity straight from the managedObject doesn't give you the full picture. Getting the Entity from the NSManagedObjectModel permits to reach the validationWarnings & validationPredicates...

  • How do i know in the detail view what cell in tableview was selected?

    - by Daniel Rotaru
    how can i know what tableview cell was selected?(being in the detail view) The problem is that. I have an table view controller. Here are parsed from the internet entries to the table. So it's a dynamic tabe view that loads from internet. I will not know how many entries will be in the table so i will not know what details view to call when i click a row. So i have maked one view. This view contains an calendar. On this calendar(wich is the detail iew) i will parse data from internet depending on the selected row. For exemple: i have table: entry 1, entry 2,entry 3,entry 4 When i click entry 2 i need to call a php with the argument entry 2. The php will know what entry on the table i have selected and will generate me the correct xml that i will parse. Here is my tableview didSelectRow function: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic -- create and push a new view controller if(bdvController == nil) bdvController = [[BookDetailViewController alloc] initWithNibName:@"BookDetailView" bundle:[NSBundle mainBundle]]; Villa *aVilla = [appDelegate.villas objectAtIndex:indexPath.row]; [self.navigationController pushViewController:bdvController animated:YES] And here is my self view function on detailviewcontroller: -(void)loadView { [super loadView]; self.title=@"Month" UIBarButtonItem *addButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"ListView" style:UIBarButtonItemStyleDone target:self action:@selector(add:)]; self.navigationItem.rightBarButtonItem = addButtonItem; calendarView = [[[KLCalendarView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 373.0f) delegate:self] autorelease]; appDelegate1 = (XMLAppDelegate *)[[UIApplication sharedApplication] delegate]; myTableView=[[UITableView alloc]initWithFrame:CGRectMake(0, 260, 320, 160)style:UITableViewStylePlain]; myTableView.dataSource=self; myTableView.delegate=self; UIView *myHeaderView=[[UIView alloc]initWithFrame:CGRectMake(0, 0, myTableView.frame.size.width,2)]; myHeaderView.backgroundColor=[UIColor grayColor]; [myTableView setTableHeaderView:myHeaderView]; [self.view addSubview:myTableView]; [self.view addSubview:calendarView]; [self.view bringSubviewToFront:myTableView]; } I think that here in self load i need to make the if procedure.. If indexPath.row=x parse fisier.php?variabila=title_of_rowx but the question is how i know the indexPath variable?

  • How to pass an int value on UIButton click inside UITableView

    - by Toran Billups
    So I have a view controller with a single UITableView that shows a string to the user. But I needed a way to have the user select this object by id using a normal UIButton so I added it as a subview and the click event works as expected. The issue is this - how can I pass an int value to this click event? I've tried using attributes of the button like button.tag or button.accessibilityhint without much success. How do the professionals pass an int value like this? Also it's important that I can get the actual [x intValue] from the int later in the process. A while back I thought I could do this with a simple NSLog(@"the actual selected hat was %d", [obj.idValue intValue]); But this doesn't appear to work (any idea how I can pull the actual int value directly from the variable?). The working code I have is below - (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 ([self.hats count] > 0) { Hat* obj = [self.hats objectAtIndex: [indexPath row]]; NSMutableString* fullName = [[NSMutableString alloc] init]; [fullName appendFormat:@"%@", obj.name]; [fullName appendFormat:@" %@", obj.type]; cell.textLabel.text = fullName; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; //add the button to subview hack UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 5, 50, 25); [button setTitle:@"Select" forState:UIControlStateNormal]; button.backgroundColor = [UIColor clearColor]; button.adjustsImageWhenHighlighted = YES; button.tag = obj.idValue; //this is my current hack to add the id but no dice :( [button addTarget:self action:@selector(action:) forControlEvents:UIControlEventTouchUpInside]; [cell.contentView addSubview:button]; //hack } return cell; } - (void)action:(id)sender { int* hatId = ((UIButton *)sender).tag; //try to pull the id value I added above ... //do something w/ the hatId }

  • Ttstyledtextlabel does not draw properly when text property is assigned multiple times

    - by user210504
    I have A ttstyledtextlabel in my uitableview cell. It has got some web URLs for images which are being rendered. But since images take some time to download i reload the cell after sometime to render the images if they have been downloaded. The problem I am facing is that during subsequent assignment of text if the size of the label changes, happens when images have been successfully loaded the label does not render properly but rather blanks out. But I see the proper label when is scroll and come back to the cell again. Anyone faced this issue or simply when the following line is executed multiple times, the Styled Label goes blank StyledView.text = [TTStyledText textFromXHTML:[self getStyledText] lineBreaks:YES URLs:YES];

  • textFieldShouldBeginEditing + UIKeyboardWillShowNotification + OS 3.2

    - by user193545
    I have multiple textfields on a UIView. I resign for a previous textField in textFieldShouldBeginEditing method, where following sequence of events are performed UIKeyboardWillHideNotification is received corresponding to that field where the keyboard for the previous field is hidden. the method textFieldShouldBeginEditing returns a YES and then UIKeyboardWillShowNotification is received where the keyboard for the current field is displayed. However, in OS 3.2 even though textFieldShouldBeginEditing returns a YES, UIKeyboardWillShowNotification for the current field is not received. The logic works for OS < 3.2 Any ideas where I might be doing wrong?
