• Detect backspace in UITextField

  - by marcc

  Is there any way to detect when the backspace/delete key is pressed in the iPhone keyboard on a UITextField that is empty? I want to know when backspace is pressed only if the UITextField is empty. Based on the suggestion from @Alex Reynolds in a comment, I've added the following code while creating my text field: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleTextFieldChanged:) name:UITextFieldTextDidChangeNotification object:searchTextField]; This notification is received (handleTextFieldChanged function is called), but still not when I press the backspace key in an empty field. Any ideas? There seems to be some confusion around this question. I want to receive a notification when the backspace key is pressed. That's it. But the solution must also work when the UITextField is already empty.

• iPhone SDK: Transparent tableviewcell isn't transparent?

  - by Harkonian

  I have a UITableViewController that has a background image. I am setting the image for the tableview like this: [self.view setBackgroundColor: [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: @"background1.jpg"]]]]; The problem is, each of my custom tableview cells get the same background image--it's repeated in each cell. As a test, I tried making everything in my cell transparent with an alpha of 0.0, but even then although I can't see any of the labels in each cell, I still see the background image repeated in each cell: cell.backgroundColor = [UIColor clearColor]; cell.contentView.backgroundColor = [UIColor clearColor]; cell.contentView.alpha = 0.0; cell.alpha = 0.0; Any suggestions on how to get my table's background image to stop repeating in each cell would be appreciated!

• How can I use OCMock to verify that a method is never called?

  - by Justin Voss

  At my day job I've been spoiled with Mockito's never() verification, which can confirm that a mock method is never called. Is there some way to accomplish the same thing using Objective-C and OCMock? I've been using the code below, which works but it feels like a hack. I'm hoping there's a better way... - (void)testSomeMethodIsNeverCalled { id mock = [OCMockObject mockForClass:[MyObject class]]; [[[mock stub] andCall:@selector(fail) onObject:self] forbiddenMethod]; // more test things here, which hopefully // never call [mock forbiddenMethod]... } - (void)fail { STFail(@"This method is forbidden!"); }

• SSL cert install in Mongrel

  - by normalocity

  Running a RoR app. I've created a self-signed SSL cert for my test/dev environment, which consists of a single mongrel, and Mac OS X Leopard. Can I install the SSL cert in such a way that mongrel will use it, or do I have build a different server stack to handle SSL (e.g. Apache in front of a mongrel cluster), and install the cert inside of Apache? For my production server, I'll eventually build a server stack like this, so it's no big deal if I have to go that direction - it's just a question of now or later. Thanks!

• Dynamically load nib for iPhone/iPad within view controller

  - by qui

  Hello I have converted an iPhone application using the wizard like thing in XCode into a universal app. It builds fine but obviously looks a bit rubbish in some areas :) I need to load nibs according to which device is being used. I dont wish to create my view controllers using initWithNib as I already have code to create the controllers with some data (initWithMyLovelyData) which doesnt do anything to do with nib loading. I know to find out the device you use UI_USER_INTERFACE_IDIOT() so I tried overriding the initWithNibName within the actual view controllers themselves, assuming they get called internally somehow. But it's not working as I guess I am unsure of the syntax. I have tried if(ipad..) self = [super initWithNibName:@"MyIpadNib" bundle:nibBundleOrNil]; And that doesnt work :/ EDIT - I know I have massively edited this, made my question a bit more specific after doing some more research - apologies!

• addSubview animation

  - by Mike

  I have main UIView where I display different data. Then I put a button, which displays subview like this: - (IBAction) buttonClicked: (id) sender { UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(25,25,50,20)]; UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(25,25, 50,25)]; newLabel.text = @"some text"; [newView addSubview: newLabel]; [self.view addSubview: newView]; [newLabel release]; [newView release]; } newView appears fine, but it doesn't animate itself any way, it just appears immediately. How can I add some kind of animation when newView appears? Like zoom or slide down or something like that. Is there some simple code?

• Local Declaration "x" hides instance variable xcode warning

  - by Michael Robinson

  I've been have trouble understand this problem. If I change the variable name fifthViewController the error goes away but the view controller doesn't load. Lost. Once again it's probably something simple. Thanks in advance. Here is the code: { FifthViewController *fifthViewController = [[FifthViewController alloc] initWithNibName:@"FifthView" bundle:nil]; fifthViewController.transactionID = transactionID; [self.navigationController pushViewController:fifthViewController animated:NO]; [fifthViewController release]; }

• Memory management in objective-c

  - by prathumca

  I have this code in one of my classes: - (void) processArray { NSMutableArray* array = [self getArray]; . . . [array release]; array = nil; } - (NSMutableArray*) getArray { //NO 1: NSMutableArray* array = [[NSMutableArray alloc]init]; //NO 2: NSMutableArray* array = [NSMutableArray array]; . . . return array; } NO 1: I create an array and return it. In the processArray method I release it. NO 2: I get an array by simply calling array. As I'm not owner of this, I don't need to release it in the processArray method. Which is the best alternative, NO 1 or NO 2? Or is there a better solution for this?

• NSMutableURLRequest not obeying my timeoutInterval

  - by kubi

  I'm POST'ing a small image, so i'd like the timeout interval to be short. If the image doesn't send in a few seconds, it's probably never going to send. For some unknown reason my NSURLConnection is never failing, no matter how short I set the timeoutInterval. // Create the URL request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:0.00000001]; /* Populate the request, this part works fine */ [NSURLConnection connectionWithRequest:request delegate:self]; I have a breakpoint set on - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error but it's never being triggered. My images continue to be posted just fine, they're showing up on Tumblr despite the tiny timeoutInterval.

• UIBarButtonItem: target-action not working?

  - by Jacob Relkin

  Hey fellas, I've got a custom view inside of a UIBarButtonItem, set by calling -initWithCustomView. OK, so the view renders fine, but when I tap it, it doesn't call the method that I set as the UIBarButtonItem's action property. Oh, and I have verified that my -deselectAll method works fine. Here's my code: UIImageView *SOCImageView = [[ UIImageView alloc ] initWithImage:[ UIImage imageNamed: @"cancel_wide.png" ] ]; SOItem.leftBarButtonItem = [[ UIBarButtonItem alloc ] initWithCustomView: SOCImageView ]; [ SOCImageView release ]; [ SOItem.leftBarButtonItem setTarget: self ]; [ SOItem.leftBarButtonItem setAction: @selector( deselectAll ) ]; Thanks a million

• composite colors : CALayer and blend mode on iPhone

  - by Ali

  I'm trying to use core image on the iphone. I'm able to composite my colors using quartz to draw an uiview, but i want to separate each component into CALayer (UIview consume more resources). So i have a white mask i want to use to filter a background bitmap, and i want to try diffrent blending mode. UNfortunately, the layers are only "adding" their colors. Here is my code : @implementation WhiteLayerHelper - (void)drawLayer:(CALayer *)theLayer inContext:(CGContextRef)myContext { // draw a white overlay, with special blending and alpha values, so that the saturation can be animated CGContextSetBlendMode(myContext,kCGBlendModeSaturation); CGContextSetRGBFillColor(myContext,1.0,1.0,1.0,0.9); CGContextFillRect(myContext,[UIScreen mainScreen].bounds); } @end And here is the main view drawrect code, where i use my CALayer : - (void)drawRect:(CGRect)rect { //get the drawing context CGContextRef myContext = UIGraphicsGetCurrentContext(); // draw the background [self fillContext:myContext withBounds:m_overlayRect withImage:m_currentImage]; [whiteLayer renderInContext:myContext]; } Is there something wrong ?

• Prevent wsgi from modifying 401 responses.

  - by Gary van der Merwe

  If I have the following pylons controller: def challange(self): response.status = '401 Unauthorized' return 'You are not logged in.' I would expect to see 'You are not logged in.' But I see : Unauthorized This server could not verify that you are authorized to access the document you requested. Either you supplied the wrong credentials (e.g., bad password), or your browser does not understand how to supply the credentials required. WSGI Server I have disabled the pylons error middleware. But the wsig server seems to be modifying the response. How do I stop this?

• jquery ui tabs major style change

  - by Jonah

  I am using jquery UI tabs and I need to majorly change the styling on it. I need to rempve the background image, the borders, almost everything. I need it to look minimal, and not like it's self contained. What's the best way to do this? I need to use the default UI styling for the calendar widget however, which is on the same page. I've done a lot of research and everyone seems to point to the theme-roller. However, i do not just want to change the colors and border radii. I need to delete crap. theme-roller seems to be just change things like colors (not really useful for the real world) Is it even worth using jquery UI for my tabs?

• Google Appengine and Python exceptions

  - by Jim

  In my Google Appengine application I have defined a custom exception InvalidUrlException(Exception) in the module 'gvu'. Somewhere in my code I do: try: results = gvu.article_parser.parse(source_url) except gvu.InvalidUrlException as e: self.redirect('/home?message='+str(e)) ... which works fine in the local GAE development server, but raises <type 'exceptions.SyntaxError'>: invalid syntax (translator.py, line 18) when I upload it. (line 18 is the line starting with 'except') The problem seems to come from the 'as e' part: if I remove it I don't get this exception anymore. However I would like to be able to access the raised exception. Have you ever encountered this issue? Is there an alternative syntax?

• How to enlarge dynamically an UILabel (label and font size)?

  - by Flocked

  Hello, Im currently working on an iPhone project. I want to enlarge dynamically an UILabel in Objective-C like this: How is this possible? I thought I have to do it with CoreAnimation, but I didn't worked. Here is the code I tried: UILabel * fooL = //[…] fooL.frame = CGRectMake(fooL.frame.origin.x, fooL.frame.origin.y, fooL.frame.size.width, fooL.frame.size.height); fooL.font = [UIFont fontWithName:@"Helvetica" size:80]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:0.5]; [UIView setAnimationBeginsFromCurrentState:YES]; fooL.font = [UIFont fontWithName:@"Helvetica" size:144]; //bigger size fooL.frame = CGRectMake(20 , 44, 728, 167); //bigger frame [UIView commitAnimations]; The problem with this code is that it doesn't change the fontsize dynamically.

• _mask and Rails

  - by Eric Koslow

  So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement. Here's the code in my user.rb model: named_scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0 "} } ROLES = %w[admin student principal admissions] def roles=(roles) self.roles_mask = (roles & ROLES).map { |r| 2**ROLES.index(r) }.sum end def roles ROLES.reject { |r| ((roles_mask || 0) & 2**ROLES.index(r)).zero? } end def role? roles.include? role.to_s end def role_symbols roles.map(&:to_sym) end I'm using Rails 3 and Ruby 1.9.2dev Thank you

• URLEncoding a string with Objective-C

  - by Chris

  I'm trying to URL encode a string to form a GET request from objective-c. NSString *params = @"'Decoded data!'/foo.bar:baz"; NSRunAlertPanel( @"Error", [params urlEncoded], @"OK", nil, nil ); This is the category extending NSString -(NSString *) urlEncoded { NSString *encoded = (NSString *)CFURLCreateStringByAddingPercentEscapes( NULL, (CFStringRef)self, NULL, (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ", kCFStringEncodingUTF8 ); return encoded; } So the first time I run it I get back 1606410046ecoded 1606410784ata2270.000000foo.bar0X1.001716P-1042baz from the dialog box. Immediately after I run it again I get this 1606410046ecoded 1606410944ata227369374562920703448982951250259562309742470533728899744288431318481119278377104028261651081181287077973859930826299575521579020410425419424562236383226511593137467590082636817579938932512039895040.000000foo.bar0X1.66E6156303225P+771baz Then if I run it AGAIN it goes back to the first one. It's really weird. If params is set to @"&" or @" " I just get back a "2" (w/o the quotes) in the dialog box. Also is there a way I can have the % signs be shown in the alert dialog? Thanks

• List of dict in Python

  - by plalex

  Hi everybody, I've got a list of dict in Python: dico_cfg = {'name': entry_name, 'ip': entry_ip, 'vendor': combo_vendor, 'stream': combo_stream} self.list_cfg.append(dico_cfg) I append to my list a lot of dict in the same way. Now I would like to delete one dict and only one dict in this list? What is the best way to proceed? I've try with the index of the list, but when I remove a dict from the list, the index is modify, so after some random remove my index doesn't correspond anymore to the dict I want to remove in my list. I hope that is clear. Maybe I can add an "id" row in my dict, so I can ask to remove more preciously the dict I want. I'll ask to remove the dict where id is equal to the id's dict I want to remove. How can I do that? I hope I'm enough clear. Sorry but I'm a newbie in Python.

• XAML trigger as StaticResource

• iPhone UIScrollView - How to animate scrolling with steady contents?

  - by timbos

  Hi all, I'm wondering if anyone knows how to prevent the contents of a uiscrollview from moving unsteadily when scrolling manually by setting the content offset. When scrolling by touch the text remains clear and steady. I would like to recreate this by animating with the animated option set to false. I'm using a timer to scroll at a given interval. The text is being drawn to a view in the contents, but it vibrates and it becomes more difficult to read clearly when animating at a greater speed. The speed varies and the scrolling must respond to changes in speed quickly. Here's some code - - (void) scrollIncrAmt:(float) amt { _currentSpeedIncr = amt; NSArray* arr = [SharedTickerInfo sharedTickerInfo].sDataArray; DataObj* tdObj = [arr objectAtIndex:_row]; if ( ![tdObj isDirLeft] ) { amt = -amt; } float scrollTo = self.scrollView.contentOffset.x + amt; [scrollView setContentOffset:CGPointMake(scrollTo, 0.0f) animated:NO]; }

• Why is UIApplicationWillChangeStatusBarFrameNotification not sent when the in-call status bar is sho

  - by Sbrocket

  I've been trying to listen for changes in the status bar height – such as when the in-call status bar is shown or hidden – by listening for the UIApplicationWillChangeStatusBarFrameNotification notification to be sent. Fairly straightforward code here... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarWillChangeFrame:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil]; But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called. According to the documentation, UIApplicationWillChangeStatusBarFrameNotification Posted when the application is about to change the frame of the status bar. The userInfo dictionary contains an NSValue object that encapsulates a CGRect structure expressing the location and size of the new status bar frame. Use UIApplicationStatusBarFrameUserInfoKey to access this value. Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.
