  • CALayers didn't get resized on its UIView's bounds change. Why?

    - by Geri
    I have a UIView which has about 8 different CALayer sublayers added to its layer. If I modify the view's bounds (animated), then the view itself gets shrinked (I checked it with a backgroundColor), but the sublayers' size remains unchanged. How to solve this? I've just started googleing but haven't found any useful. Thanks in advance.

  • NSInvocationOperation and main thread

    - by kpower
    Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

  • How to do a natural sort on an NSArray?

    - by Cory Imdieke
    I've got an array of objects, and I need them sorted by their "title" key. It's currently working, though it's using an ASCII sort instead of a natural sort. The titles are filenames, so they look like this: file1 file2 file3 ... file10 file11 file12 I'm getting, as you would expect: file1 file10 file11 file12 file2 file3 ... Does anyone know if there is a way built-in to the NSArray sorting functionality to get this natural sorting as opposed to the alphabetical sort? I found some generic algorithms, but I was hoping for something built-in...

  • How can I write a scrolling text in cocos2d ?

    - by srikanth rongali
    I have a text and it should be abled to scrolled only up and down to see entire text. and my application is a game and written in cocos2d. So, I have layers. There is also an image(CCSprite) adjacent to text. The text should be scrolled and the image have a touchesEnded: property. I used CCLabel for text and CCParallaxNode to add the text. But the text appears like a continues paragraph. But, my text should have different lines. My text is like this. //text starts Hey Player. Do you want to play the game right now then play. Do you want to practice or Play? what want to do? ...text continues //text ends What should I use for this ? Thank you.

  • UIViewTableCell didSelectRowAtIndexPath is calling but not pushing a view controller

    - by Kenneth
    Hi guys, so im having a UIViewController view with a UITableView. So the UIViewController class name is SelectionScreen. The UITableView class name is SelectionScreenTable. Picture: http://img717.imageshack.us/i/screenshot20100609atpm0.png/ I have declared a UITableView *selectionTable in SelectionScreen class and connected it to the xib file of the SelectionScreen what the problem is , is that when i click a row in the table,it stays selected as highlighted blue, it calls the didSelectRowAtIndexPath (checked with NSLog) but not pushing a new view which is called(GraphView). This is the code which i use to call the new controller WHICH WORKS with a normal button GraphView *aSelectionScreenViewController = [[GraphView alloc] initWithNibName:@"GraphView" bundle:nil]; [self presentModalViewController:aSelectionScreenViewController animated: YES]; [aSelectionScreenViewController release]; I searched around and found that I need to set a delegate for the table in the UITableView class itself on the viewload tableview.delegate = self; or self.tableview.delegate = self; But it was not working. the controller was still not being pushed, and yes i have checked the controller is not nil as i tried it with a simple button. So i was thinking whether i should set the delegate of the UITableView at the UIViewController instead, so i tried this code selectionTable.delegate = selectionTable.self; but obviously it did not work =\, it messed up the whole UITableView and caused all the cells to be its predefined settings. So does anybody have any idea on how i can get it to work.

  • Preserving alpha issues with loaded UIImages - how to avoid discarding alpha values on import?

    - by Peter Hajas
    My application lets the user save/load images with alpha values to the camera roll on the device. I can see in the Photos application that these images are appropriately alpha'd, as alpha'd areas just appear black. However, when I load these images back into the application using the valueForKey:UIImagePickerControllerOriginalImage message to the info dictionary from (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info, the alpha values are turned to just white, making those sections opaque. Is there a way to preserve these alpha values?

  • Inactive area after device rotation

    - by Sébastien
    Hi all, I don't understand what's wrong in my very simple application with device rotation : I built my view with interface builder. (See screen capture here) I specified <key>UIInterfaceOrientation</key><string>UIInterfaceOrientationLandscapeRight</string> in my info.plist file. I had a (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {return YES;} in my root view controller. The area on the left (shown in red on the capture), around 20 pixel width, keeps inactive (nothing append if I hit a button in this area). In fact the full screen is active only in portrait mode, in landscape right mode there is this 20 pixels width inactive area, in landscape left mode this inactive area is on the right, in portrait upside down mode this area is on the bottom. I read lots of posts and documentation about UIView rotation, but I did not find anything to solve this problem (I tried to play with view.frame and view.bounds without any success). Anybody has an idea ? Thanks a lot. Regards. Sébastien.

  • NSMutableArray withObject(UIImageView *)

    - by pureman
    I am trying to load an NSMutableArray with UIImageViews. Everything is going fine with that. Unfortunately, I have no idea how to use the objects when they are in the mutable array. Here is some code: UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; NSMutableArray *array = [NSMutableArray new]; [array loadWithObject:(UIImageView *)imageView]; [imageView release]; That kind of sets up what I've done. Here's what I want to do: [array objectAtIndex:5].center = GCRectMake(0, 0); but that doesn't work. How can I do this??

  • White bar at the bottom of root view!

    - by Sam
    Hi, I have two view controllers in the app. When the app starts, the layout of the root view controller's view is just fine. When a button is clicked, the view controller switches to the other one - which shows fine too. However, when the view is switched back to the root view, the contents are shifted UP by about 20 pixels, leaving a white bar at the bottom! - and it was not there when the app had started. Has anyone seen this? Any idea what's going on there? Thanks, Sam.

  • How to add data manually in core data entity

    - by pankaj
    Hi I am working on core data for the first time. I have just created an entity and attributes for that entity. I want to add some data inside the entity(u can say i want to add data in a table), earlier i when i was using sqlite, i would add data using terminal. But here in core data i am not able to find a place where i can manually add data. I just want to add data in entity and display it in a UITableView. I have gone through the the documentation of core data but it does not explain how to add data manually although it explains how i can add it programmiticaly but i dont need to do it programically. I want to do it manually. Thanks in advance

  • Can't set default value of string property to "" in the Xcode CoreData model designer

    - by glenc
    I have an entity in my datamodel with a string property that is currently optional, and I'd like to convert this property to a required property with a default value of the empty string. As others have discovered, leaving the default value blank results in validation errors (since the designer interprets this as NULL), but trying '', "", or @"" as the default value results in those literal characters being interpreted as the default, rather than the empty zero-length string, as desired. I did find this thread on Google, however, apart from the solution being really ugly (model definition split between the .xcdatamodel and objc source), it also doesn't work for lightweight migrations because those migrations are done solely based on the .xcdatamodel files and the objc logic from your entity implementations isn't loaded. Is there any way to achieve this in the data model designer?

  • Apple's Sample App TopSongs has 26 Leaks, Ugh!

    - by RoLYroLLs
    Hey all, I've been building an app for a client and part of it uses Apple's TopSongs sample app to download data on another thread. I finally got enough done to start testing that part and found 1000 leaks!!! A closer look at the leaks made me check TopSongs for leaks, since none of the my methods were in leaks report. Running TopSongs returned 26 leaks. Not quite sure how to fix them, or if they are part of some library from Apple. I bet you're asking if it has 26, why do you have 1000? Well, I use their sample to make roughly 48 calls to webservices to get all the information needed on initial install (48 calls x 26 leaks = 1248 leaks!!). Later it makes at least 12 calls + 4 to check for updated information on other sections of the app. Can't do a thing about it, can't make one call, or less calls, please don't comment about this part. I seen people respond to posts that aren't necessarily answering the question the user originally posted, which in this case is has anyone tried patching up the leaks, if they are patchable, or is this a bug in Apple's libraries? Thanks so much.

  • Tableview not updating correctly after adding person

    - by tazboy
    I have to be missing something simple here but it escapes me. After the user enters a new person to a mutable array I want to update the table. The mutable array is the datasource. I believe my issue lies within cellForRowAtIndexPath. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { TextFieldCell *customCell = (TextFieldCell *)[tableView dequeueReusableCellWithIdentifier:@"TextCellID"]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"]; if (indexPath.row == 0) { if (customCell == nil) { NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"TextFieldCell" owner:nil options:nil]; for (id currentObject in nibObjects) { if ([currentObject isKindOfClass:[TextFieldCell class]]) customCell = (TextFieldCell *)currentObject; } } customCell.nameTextField.delegate = self; cell = customCell; } else { if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; cell.textLabel.text = [[self.peopleArray objectAtIndex:indexPath.row-1] name]; NSLog(@"PERSON AT ROW %d = %@", indexPath.row-1, [[self.peopleArray objectAtIndex:indexPath.row-1] name]); NSLog(@"peopleArray's Size = %d", [self.peopleArray count]); } } return cell; } When I first load the view everything is great. This is what prints: PERSON AT ROW 0 = Melissa peopleArray's Size = 2 PERSON AT ROW 1 = Dave peopleArray's Size = 2 After I add someone to that array I get this: PERSON AT ROW 1 = Dave peopleArray's Size = 3 PERSON AT ROW 2 = Tom peopleArray's Size = 3 When I add a second person I get: PERSON AT ROW 2 = Tom peopleArray's Size = 4 PERSON AT ROW 3 = Ralph peopleArray's Size = 4 Why is not printing everyone in the array? This pattern continues and it only ever prints two people, and it's always the last two people. What the heck am I missing?

  • How to tell if you touched a CCLabel? (Cocos2d Question)

    - by RexOnRoids
    How to tell if you touched a CCLabel? The following code obviously does not work well enough because it only tests for point equality. Naturally touch point will not necessarily be equal to the position property of the CCLabel (CCNode). How to I tell if a Touch point has fallen within the "rectangle?" of the CCLabel? - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; self.myGraphManager.isSliding = NO; if(CGPointEqualToPoint(location, label1.position)){ NSLog(@"Label 1 Touched"); }else if(CGPointEqualToPoint(location, label2.position)){ NSLog(@"Label 2 Touched"); }else if(CGPointEqualToPoint(location, label3.position)){ NSLog(@"Label 3 Touched"); }else if(CGPointEqualToPoint(location, label4.position)){ NSLog(@"Label 4 Touched"); }else if(CGPointEqualToPoint(location, label5.position)){ NSLog(@"Label 5 Touched"); }else if(CGPointEqualToPoint(location, label6.position)){ NSLog(@"Label 6 Touched"); } NSLog(@"Touch Made!"); } }

  • Table cell in a split-view controller - selected cell becomes deselected when called by reloadData

    - by bpapa
    I'm working on a universal app that uses a SplitViewController to present a master-detail view. In the iPad HIG on Split Views, Apple states: In general, indicate the current selection in the left pane in a persistent way. This behavior helps people understand the relationship between the item in the left pane and the contents of the right pane. This is important because the contents of the right pane can change, but they should always remain related to the item selected in the left pane. So I'm trying to maintain selection state on the left. Easy enough when the user taps, I just remove the deselectRowAtIndexPath:animated: message from tableView:didSelectRowAtIndexPath: implementation. But, I also want the selection state to show up by default (without a user tap). I wound up putting this in my tableView:cellForRowAtIndexPath: implementation: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { if (cellShouldBeSelected) cell.selected = YES; else cell.selected = NO; } The behavior I'm seeing, is that when the cells finall appear, for a fraction of a section the cell is indeed selected, but then the selection disappears without any user interaction. Any ideas? I set the new clearsSelectionOnViewWillAppear property to NO, but that doesn't seem to fix it, and it shouldn't really matter because I'm marking the cell as selected long after viewWillAppear is called - I'm actually doing it after some network activity and then sending the table view a reloadData message.

  • Access custom label property at didSelectRowAtIndexPath.

    - by Mr. McPepperNuts
    I have a UILabel for each cell at cellForRowAtIndexPath. UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; I want to access that string "myString" at didSelectRowAtIndexPath using indexpath. NSString *anotherString = cell.textLabel.text; returns null. Now if at cellForRowAtIndexPath, I did something like cell.textLabel.text = theString; then the didSelectRowAtIndexPath returns the appropriate cell. My question is, how can I access the text in the UILabel I apply to the cell, at didSelectRowAtIndexPath? Also, logging the cell in didSelectRowAtIndexPath returns cell: <UITableViewCell: 0x5dcb9d0; frame = (0 44; 320 44); autoresize = W; layer = <CALayer: 0x5dbe670>> Edit: NSString *myString = [[results objectAtIndex:indexPath.row] valueForKey:@"name"]; //cell.textLabel.text = myString; CGFloat width = [UIScreen mainScreen].bounds.size.width - 50; CGFloat height = 20; CGRect frame = CGRectMake(10.0f, 10.0f, width, height); UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; cellLabel.textColor = [UIColor blackColor]; cellLabel.backgroundColor = [UIColor whiteColor]; cellLabel.textAlignment = UITextAlignmentLeft; cellLabel.font = [UIFont systemFontOfSize:14.0f]; [cell.contentView addSubview:cellLabel]; [cellLabel release]; return cell;

  • Can I detect if higher subview has been touched?

    - by Kevin Beimers
    I've got a big UIView that responds to touches, and it's covered with lots of little UIViews that respond differently to touches. Is it possible to touch anywhere on screen and slide around, and have each view know if it's being touched? For example, I put my finger down on the upper left and slide toward the lower right. The touchesBegan/Moved is collected by the baseView. As I pass over itemView1, itemView2, and itemView3, control passes to them. If I lift my finger while over itemView2, it performs itemView2's touchesEnded method. If I lift my finger over none of the items, it performs baseView's touchesEnded. At the moment, if I touch down on baseView, touchEnded is always baseView and the higher itemViews are ignored. Any ideas?
