  • Added buttons, webview, added outlets, but can't play with them in the code...

    - by Tom
    Hi! I made a toolbar with two buttons on it. I then created two outlets in my class controller. Then I hooked the the controller to the buttons and selected the outlets. Finally I rewritten the class files (that added: IBOutlet id next; IBOutlet id previous; to my .h file). So now, everything looks okay. But then I try somewhere in the code to change the state of one of my button like this: next.enabled = YES; I tried with self. too but unfortunately I receive this error message: error: request for member 'enabled' in something not a structure or union Do you have any idea of what's happening there? And yes I have: #import <UIKit/UIKit.h> :) Using: [next setEnabled:YES]; gives me no error but still doesn't work... And finally, for documenting purposes here's the whole method: - (void)viewDidLoad { [super viewDidLoad]; if (!self.currentLevel) { self.currentLevel = @"1"; } NSArray *etape = [self.etapes objectForKey:self.currentLevel]; if ([etape count] > 0) { self.navigationItem.title = [etape objectAtIndex:1]; if ([etape count] > 1) { [next setEnabled:YES]; } } else { self.navigationItem.title = @"Aucune étape"; } } When I do: NSLog(@"%@", [next class]); It returns (null) ... I guess it is supposed to be UIBarButtonItem... It seems that it is impossible to play with any outlets even if I don't receive any errors while playing with them...

  • Three20 TTSectionedDataSource row height

    - by Ward
    Hey there, I'm using Three20 to create a table with several textfields for user registration. I've found two possible methods using Three20. The first uses the TTSectionedDataSource's tableDidLoadModel method to manually add UI components and the second adds custom items that contains pre formatted UI components. The second option seems way more complex and I'm having a difficult time accessing the individual fields. So if one field is a textfield for the username, I need to access the field to submit the username and it doesn't seem like there's an easy answer. The first option gives me a lot of flexibility, but I can't figure out how to set the individual row heights. One row may have a label above a text field, another may have an image, etc. Is there a method that can be used in TTSectionedDataSource that will allow me to set the height for each row? Thus far, I'm using method one and creating UIViews to hold a label field and a text field. I've tried changing the frame of the uiview before it is added to the items array, but it has no affect. Any ideas?

  • NSString writeToFile operation couldn't be completed

    - by Chonch
    Hey, I have an xml file in my application bundle. I want to copy it to the documents folder at installation and then, every time the app launches, get the newest version of this file from the Internet. I use this code: // Check if the file exists in the documents folder NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; if (![[NSFileManager defaultManager] fileExistsAtPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"]]) // If not, copy it there (from the bundle) [[NSFileManager defaultManager] copyItemAtPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"OriginalFile.xml"] toPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] error:nil]; // Get the newest version of the file from the server NSURL *url=[[NSURL alloc] initWithString:@"http://www.sitename.com/webservice.asmx/webserviceName"]; NSString *results = [[NSString alloc] initWithContentsOfURL:url]; // Replace the current version with the newest one, only if it is valid if (results != nil) [results writeToFile:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; The problem is that the writeToFile command always returns NO and the file's contents remain identical to the original file I included in my app bundle. I checked the value of results and it's correct. I also made sure that the app does perform the writeToString command, but still, it always returns NO. Can anybody tell me what I'm doing wrong? Thanks,

  • How to make UIImagePickerController works under switch case UIActionSheet

    - by Phy
    -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *tempImage = [info objectForKey:UIImagePickerControllerOriginalImage]; imgview.image = tempImage; [self dismissModalViewControllerAnimated:YES]; [picker release]; } -(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { [self dismissModalViewControllerAnimated:YES]; [picker release]; } -(IBAction) calllib { img1 = [[UIImagePickerController alloc] init]; img1.delegate = self; img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:img1 animated:YES]; } all the codes above works well for taking out photos from the photo library. problem is that when i tried to use it under the UIActionSheet it does not work. i just copy the lines of codes from the -(IBAction) calllib as follow. (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { UIImage *detectface = [Utilities detectFace:imgview.image]; UIImage *grayscale = [Utilities grayscaleImage:imgview.image]; UIImage *avatars = [Utilities avatars:imgview.image]; img1 = [[UIImagePickerController alloc] init]; img1.delegate = self; img1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; switch (buttonIndex) { case 0: [self presentModalViewController:img1 animated:YES]; imgview.image = detectface; break; case 1: [self presentModalViewController:img1 animated:YES]; imgview.image = grayscale; break; case 2: [self presentModalViewController:img1 animated:YES]; imgview.image = avatars; break; default: break; } } it does not work. can somebody help me to figure out what is the problem? the switch case works perfectly without the [self presentModalViewController:img1 animated:YES]; ... thanks

  • iPad keyboard will not dismiss if navigation controller presentation style is "form sheet".

    - by Kalle
    UPDATE: This is apparently "works as intended" classed by Apple. See accepted answer below for details. Update: this question is about a behavior discovered in the iPad keyboard, where it refuses to be dismissed if shown in a modal dialog with a navigation controller. Basically, if I present the navigation controller with the following line: navigationController.modalPresentationStyle = UIModalPresentationFormSheet; The keyboard refuses to be dismissed. If I comment out this line, the keyboard goes away fine. ... I've got two textFields, username and password; username has a Next button and password has a Done button. The keyboard won't go away if I present this in a modal navigation controller. WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; [self.view addSubview:b.view]; DOES NOT WORK broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; navigationController.modalPresentationStyle = UIModalPresentationFormSheet; navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release]; If I remove the navigation controller part and present 'b' as a modal view controller by itself, it works. Is the navigation controller the problem? WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; b.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:b animated:YES]; [b release]; WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release];

  • Save UITextView content in NSString.

    - by camilo
    Hi, I'm trying to save the contents of an UITextView into a NSString which I will somehow persist later. The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after editing the textView) I can save its content into a String (or something else that I can later access and share through different views and persist in the database)? Thanks a lot. Pretty sure it is simple, but I'm honestly not finding the solution.

  • Enterprise Native Mobile Application Development

    - by ahsteele
    I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks. Note: As an organization we primarily use BlackBerry devices but are other platform curious.

  • Multiple errors while adding searching to app

    - by Thijs
    Hi, I'm fairly new at iOS programming, but I managed to make a (in my opinion quite nice) app for the app store. The main function for my next update will be a search option for the app. I followed a tutorial I found on the internet and adapted it to fit my app. I got back quite some errors, most of which I managed to fix. But now I'm completely stuck and don't know what to do next. I know it's a lot to ask, but if anyone could take a look at the code underneath, it would be greatly appreciated.

  • Smooth table view like on iPod.app

    - by Gilo
    Hey folks ;), Im trying to redo the table view in the ipod.app. The one with 2 labels and the cover on the left. I want the same information there. I mean the cover plus all the other MPMediaItem stuff. Everything works fine. I can build the table and get all the information from the music library I need. My only problem is that my table is far away from being smooth. It lacks. When I remove the MPMediaArtworkItem from the table its super fast. So I guess its a problem with that. Is there any way to load the MPMediaProperties more faster? Whats the fastest way? THX in advance :)

  • UIWebView loads a local file for a long time

Is there any way to optimize the loading time?

  • When I mark a property as transient, does the type matter?

    - by mystify
    For example, I make a fullName property and set it to transient. Does it matter what data type that property is, in this case? For example, does it matter if it's set to int or string? As far as I get it, a transient property is almost "ignored" by Core Data. I make my accessors for that and when someone accesses fullName, I simply construct a string and return that. Did I miss something?

  • Should we use NsMutableArray in CGRectIntersect ?

    - by srikanth rongali
    To know whether two sprites cross each other or not, should we use NSMutableArray to store the sprites ? In my game one fixed sprite(player) is there. And the other is a bullet fired and if this sprite intersects player sprite, then enemy won. I have used NSMutable Array to store the bullet sprites. If I do not use NSMutableArray then even though the the bullet intersects player it is not recognizing the intersection ? I am using ( (CGRectIntersectsRect(bulletRect, playerRect)). Thank You.

  • Animating a pulsing UILabel?

    - by fuzzygoat
    I am trying to animate the color the the text on a UILabel to pulse from: [Black] to [White] to [Black] and repeat. - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:0.0]]; [UIView animateWithDuration:1 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setTextColor:[[UIColor whiteColor] colorWithAlphaComponent:1.0]];} completion:nil]; } . [self setFadeTimer:[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerFlash:) userInfo:nil repeats:YES]]; Firstly I am not sure of my method, my plan (as you can see above) was to set up a animation block and call it using a repeating NSTimer until canceled. My second problem (as you can see above) is that I am animating from black (alpha 0) to white (alpha 1) but I don't know how to animate back to black again so the animation loops seamlessly Essentially what I want is the text color to pulse on a UILabel until the user presses a button to continue. EDIT_001: I was getting into trouble because you can't animate [UILabel setColor:] you can however animated [UILabel setAlpha:] so I am going to give that a go. EDIT_002: - (void)timerFlash:(NSTimer *)timer { [[self navTitle] setAlpha:0.5]; [UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{[[self navTitle] setAlpha:0.9];} completion:nil]; } This works (BTW: I do want it to stop which is why I hooked it up to a NSTimer so I can cancel that) the only thing is that this animates from midGray to nearWhite and then pops back. Does anyone know how I would animate back from nearWhite to midGray so I get a nice smooth cycle? EDIT_003: (Solution) The code suggested by dave DeLong (see below) does indeed work when modified to use the CALayer opacity style attribute: UILabel *navTitle; @property(nonatomic, retain) UILabel *navTitle; . // ADD ANIMATION CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"opacity"]; [anim setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [anim setFromValue:[NSNumber numberWithFloat:0.5]]; [anim setToValue:[NSNumber numberWithFloat:1.0]]; [anim setAutoreverses:YES]; [anim setDuration:0.5]; [[[self navTitle] layer] addAnimation:anim forKey:@"flash"]; . // REMOVE ANIMATION [[[self navTitle] layer] removeAnimationForKey:@"flash__"];

  • send SMS from WAP page

    - by user217069
    This question is related to sending an SMS from a link in a WAP page? Historically I have used sms: which has worked on SonyEricsson, Nokia and other such 'legacy' devices. An example of the mark-up would be; <a href="sms:0123456789?body=test%20message">send</a> I am aware that i-phone does not allow you to specify the body. If the body tag is present then the device closes the browser and opens the SMS application but does not go as far as taking the user to message creation. As such the following does not really work; <a href="sms:0123456789?body=test%20message">send</a> however, this partially does... in that it takes the user to the editor and selects the recipient. <a href="sms:0123456789">send</a> My tests with Android (HTC desire) cause the message editor to crash (with the above examples). I have managed to get the message editor to open successfully but not managed to pass any details (recipient or message body) using; <a href="sms://0123456789">send</a> Note the :// which is not correct according to the Nokia specs. Has anyone had any more success? Sorry if this is a bit hazy, its probably more of a discussion than a question.

  • How to stop OpenGL from applying blending to certain content? (see pics)

    - by RexOnRoids
    Supporting Info: I use cocos2d to draw a sprite (graph background) on the screen (z:-1). I then use cocos2d to draw lines/points (z:0) on top of the background -- and make some calls to OpenGL blending functions before the drawing to SMOOTH out the lines. Problem: The problem is that: aside from producing smooth lines/points, calling these OpenGL blending functions seems to "degrade" the underlying sprite (graph background). As you can see from the images below, the "degraded" background seems to be made darker and less sharp in Case 2. So there is a tradeoff: I can either have (Case 1) a nice background and choppy lines/points, or I can have (Case 2) nice smooth lines/points and a degraded background. But obviously I need both. THE QUESTION: How do I set OpenGL so as to only apply the blending to the layer with the Lines/Points in it and thus leave the background alone? The Code: I have included code of the draw() method of the CCLayer for both cases explained above. As you can see, the code producing the difference between Case 1 and Case 2 seems to be 1 or 2 lines involving OpenGL Blending. Case 1 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Commenting out the following two lines induces a problem of making it impossible to have smooth lines/points, but has merit in that it does not degrade the background sprite.*/ //glEnable (GL_BLEND); //glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } } Case 2 -- MainScene.h (CCLayer): -(void)draw{ int lastPointX = 0; int lastPointY = 0; GLfloat colorMAX = 255.0f; GLfloat valR; GLfloat valG; GLfloat valB; if([self.myGraphManager ready]){ valR = (255.0f/colorMAX)*1.0f; valG = (255.0f/colorMAX)*1.0f; valB = (255.0f/colorMAX)*1.0f; NSEnumerator *enumerator = [[self.myGraphManager.currentCanvas graphPoints] objectEnumerator]; GraphPoint* object; while ((object = [enumerator nextObject])) { if(object.filled){ /*Enabling the following two lines gives nice smooth lines/points, but has a problem in that it degrades the background sprite.*/ glEnable (GL_BLEND); glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glHint (GL_LINE_SMOOTH_HINT, GL_DONT_CARE); glEnable (GL_LINE_SMOOTH); glLineWidth(1.5f); glColor4f(valR, valG, valB, 1.0); ccDrawLine(ccp(lastPointX, lastPointY), ccp(object.position.x, object.position.y)); lastPointX = object.position.x; lastPointY = object.position.y; glPointSize(3.0f); glEnable(GL_POINT_SMOOTH); glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); ccDrawPoint(ccp(lastPointX, lastPointY)); } } } }

  • How do you uninstall old custom installs of Xcode?

    - by Jonathan
    Hi, When I install a beta, I do a custom install into a separate folder to the latest release version. I have several old beta installs. How do I uninstall the old custom versions of xcode? Can I just trash the folder? Our do I need to use Terminal? The release notes suggest to use this: $ sudo /Library/uninstall-devtools --mode=all But will this just uninstall my original official release version 3.2? Thanks.
