  • Editable CATextLayer?

    - by Ron
    I have several CATextLayers. When I doubleclick one of them, I want to be able to edit it's string. Think of text as it's handled in Keynote or many other apps. Any ideas? I thought of putting an editable textfield right in front of the layer and then dismiss it on enter, but I didn't get far. :-( I target Mac OS X 10.5 with Objective-C 2.0 and Garbage Collection. Any help or pointers would be greatly appreciated. Thanks in advance!!

  • List show/add/remove View

    - by Michael
    Looking for some best practices of UI list on iPhone which has item add/modify/delete functions. Please refer to some sample codes or articles to build user friendly interface. The main application is tab bar application and one of the tabs supposed to show item management. The item itself consisting of 3 text items, first one can be label, it's short, the rest if it's not terribly complicated I would like to show below with small font or show when user taps on item entering edit mode... Not sure how to design all this and which views to use.

  • why can't I set a new instance's delegate as self?

    - by Guille10k
    I have a uipickerview, which appears with an ActionSheet. All this is in a class "MultiPicker". I create a new instance from "FirstViewController" this way: multiPicker *multiPic = [[multiPicker alloc]init]; multiPic.delegate = self; [multiPic action:aRunIndex]; And inside "multiPicker", in "action:" UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:title delegate:otroDelegate cancelButtonTitle:nil destructiveButtonTitle:@"Cancel" otherButtonTitles:@"Done", nil]; UIPickerView *pickerView = [[[UIPickerView alloc] init] autorelease]; pickerView.tag = 101; pickerView.delegate = self; pickerView.dataSource = self; pickerView.showsSelectionIndicator = YES; [actionSheet addSubview:pickerView]; [actionSheet showInView:self.view]; I need "FirstViewController" when MultiPicker finishes, so I can update a table in FirstView. I tried setting a new delegate to MultiPicker so, it tells FirstView when it finishes. But the instruction "multipic.delegate = self" in the first piece of code mades the app crash and says "Terminating due to uncaught exception". If I simply put all "MultiPicker" code inside FirstViewController class, not in a separate one, the action sheet stay blocked when I try to push a button different from "Cancel" Any idea? Thank u

    - by joels
    Lets assume myProp is @property (retain) NSString * myProp and synthesized for us.... self.myProp = @"some value";//string literal? self.myProp = [NSString stringWithString:@"some value"]; Is there a difference here? Is the first one a string literal that doesnt get autoreleased or is it just in memory for it's current scope and I dont have to worry about it?

  • Draggable cards (touch enumeration) issue

    - by glitch
    I'm trying to let a player tap, drag and release a card from a fanned stack on the screen to a 4x4 field on the board. My cards are instantiated from a custom class that inherits from the UIImageView class. I started with the Touches sample app, and I modified the event handlers for touches to iterate over my player's card hand instead of the 3 squares the sample app allows you to move on screen. Everything works, until that is, I move the card I'm dragging near another card. I'm really drawing a blank here for the logic to get the cards to behave properly. Here's my code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSUInteger numTaps = [[touches anyObject] tapCount]; if(numTaps = 1) { for (UITouch *touch in touches) { [self dispatchFirstTouchAtPoint:[touch locationInView: self.boardCardView] forEvent:nil]; } } } -(void) dispatchFirstTouchAtPoint:(CGPoint)touchPoint forEvent:(UIEvent *)event { for (int i = 0; i<5; i++) { UIImageView *touchedCard = boardBuffer[i]; if (CGRectContainsPoint([touchedCard frame], touchPoint)) { [self animateFirstTouchAtPoint:touchPoint forView:touchedCard]; } } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { NSUInteger touchCount = 0; for (UITouch *touch in touches){ [self dispatchTouchEvent:[touch view] toPosition:[touch locationInView:self.boardCardView]]; touchCount++; } } My questions are: How do I get the touch logic to disallow other cards from being picked up by a dragging finger? Is there anyway I can only enumerate the objects that are directly below a player's finger and explicitly disable other objects from responding? Thanks!

  • Custom inputAccessoryView push my UITableView first row partially off the screen

    - by TonyMocha
    Hi For my scenario, I have a UITableView with a UITextField for the first row. While I try to set custom toolbar for keyboard with UITextField.inputAccessoryView, it pushed my first row of textfield partially off the screen. This is not happening if I avoid adding the toolbar. Refer screen shot below: I tried with NSNotification with keyboardWillShow by reposition to first row of the tableview, but it just look awkward for the table pulling out and in. It might be something to do overriding UITableView/UIScrollView, but I am out of idea how to do this. Would like to know how you guys resolve this. Thanks you!

  • How do I change the background image of my iPhone app?

    - by alJaree
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • UIButton title disappears on touch

    - by psychotik
    I want a touchable UILabel, but since that's not possible I decided to create a UIButton of type UIButtonTypeCustom. It looks how I want it to look, but when I touch it, the title disappears. I tried setting the title for state UIControlStateHighlighted but that didn't help. I know I'm doing something really silly here, but can't figure it out. I tried a few things (commented in the code below) which didn't seem to help. Here's how I'm configuring the button: UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, width, height); button.clearsContextBeforeDrawing = YES; button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; button.enabled = YES; button.hidden = NO; button.highlighted = NO; button.opaque = YES; button.selected = NO; button.userInteractionEnabled = YES; button.showsTouchWhenHighlighted = NO; [button setTitle:@"Hello World" forState:UIControlStateNormal]; button.titleLabel.font = [UIFont boldSystemFontOfSize:16]; button.titleLabel.textColor = [UIColor blackColor]; // Things I tried that didn't help //[button setBackgroundColor:[UIColor clearColor]]; //button.titleLabel.text = @"Hello World"; //[button setTitle:@"Hello World" forState:UIControlStateHighlighted]; Any ideas?

  • Can't find .js file in my mainBundle?!

    - by Nic Hubbard
    This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

  • iPhone AES encryption issue

    - by Dilshan
    Hi, I use following code to encrypt using AES. - (NSData*)AES256EncryptWithKey:(NSString*)key theMsg:(NSData *)myMessage { // 'key' should be 32 bytes for AES256, will be null-padded otherwise char keyPtr[kCCKeySizeAES256 + 1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [myMessage length]; //See the doc: For block ciphers, the output size will always be less than or //equal to the input size plus the size of one block. //That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void* buffer = malloc(bufferSize); size_t numBytesEncrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES256, NULL /* initialization vector (optional) */, [myMessage bytes], dataLength, /* input */ buffer, bufferSize, /* output */ &numBytesEncrypted); if (cryptStatus == kCCSuccess) { //the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesEncrypted]; } free(buffer); //free the buffer; return nil; } However the following code chunk returns null if I tried to print the encryptmessage variable. Same thing applies to decryption as well. What am I doing wrong here? NSData *encrData = [self AES256EncryptWithKey:theKey theMsg:myMessage]; NSString *encryptmessage = [[NSString alloc] initWithData:encrData encoding:NSUTF8StringEncoding]; Thank you

  • adding a UITableView programmatically to a UIViewController

    - by Adam
    I'm loading a UIViewController into one of my Nav controller's hierarchies, which will contain some text and some images. At the bottom, I will want to create a expandable and collapsable tableview. First off, is this idea possible? If it is, how do I add it and where do I place the data source and delegate methods? Can I just make a separate subclass of the TableViewController and then add it to my ViewController as a subview?

  • App Crashing Inspite of Being ARC Enabled

    - by proctr
    I have been working on an iOS App for sometime now and its almost ready to submit. However, when I gave it to few people for testing purposes (running iOS 5)..they reported cases where the app crashes and the home screen is displayed on the phone OR a frozen app screen appears with no response whatsoever The app is ARC enabled and Xcode shows no warnings. So, I'm relli tensed about what's going wrong. I have declared properties in the following fashion: @property (nonatomic) IBOutlet UILabel *devCountLabel; @property (nonatomic) IBOutlet UIView *splashView; Likewise other properties are declared. Could anyone provide a solution ASAP. It is mainly a network based app and thus, CoreData usage is minimum.. Anyway, I'm running out of time..So Please provide a fix asap..oh and thanks a ton for it. PS: The App doesn't crash in the simulator, so I'm guessing it has something related to memory. And the crashes are random. So, repeating a set of steps to reproduce the crash doesn't help either. For Eg. When I click a button, modalViewControllerAnimation results in normal case. Now this occurs as expected most of the time and freezes the app other times.
