  • sifr3 text doesn't load on first try?

    - by metal-gear-solid
    sifr3 text doesn't load many time first time on FF 3.5? I haven't checked on other browser. If i reload page again then it loads properly. this is my code sIFR.replace(futura, { selector: '#Homepage h1', ratios: [6, 1.24, 9, 1.13, 10, 1.15, 16, 1.09, 21, 1.06, 22, 1.07, 25, 1.04, 26, 1.06, 29, 1.03, 30, 1.05, 31, 1.03, 32, 1.05, 41, 1.04, 58, 1.03, 97, 1.02, 1.01], wmode: 'transparent', css: '.sIFR-root { background-color: none; color: #ffffff; }' });

  • Why is FF on OS X loosing jQuery-UI in click event handler?

    - by Jean-François Beauchamp
    In a web page using jQUery 1.7.1 and jQUery-UI 1.8.18, if I output $.ui in an alert box when the document is ready, I get [object Object]. However when using Firefox, if I output $.ui in a click event handler, I get 'undefined' as result. With other browsers (latest versions of IE, Chrome and Safari), the result is still [object Object] when clicking on the link. Here is my HTML Page: <!doctype html> <html> <head> <title></title> <script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.18.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { alert($.ui); // ALERT A $(document).on("click", ".dialogLink", function () { alert($.ui); // ALERT B return false; }); }); </script> </head> <body> <a href="#" class="dialogLink">Click me!</a> </body> </html> In this post, I reduced to its simplest form another problem I was having described here: $(this).dialog is not a function. I created a new post for the sake of clarity, since the real question is different from the original one now that pin-pointed where the problem resided. UPDATE: IF I replace my alerts with simply alert($); I get this result for alert A: function (selector, context) { return new jQuery.fn.init(selector, context, rootjQuery); } and this one for alert B: function (a, b) { return new d.fn.init(a, b, g); } This does not make sense to me, although I may not be understanding well enough what $ is... UPDATE 2: I can only reproduce this problem using Firefox on OS X. On Firefox running on Windows 7, everything is fine.

  • Is it possible to use .data() as a search criteria?

    - by Andrew
    I have a pretty complex chat application going on, and there are multiple chat panes, chat entries, chat submits, etc. going on in the same window. At first I was going to do something like.... <input type="text" class="chattext" id="chattext-42"> <input type="text" class="chattext" id="chattext-93"> <input type="button" class="chatsubmit" id="chatsubmit-42"> <input type="button" class="chatsubmit" id="chatsubmit-93"> ... etc. (of course this is vastly simplified, they'd be in separate divs, separate visibilities, etc) So, when they clicked on a .chatsubmit, it would then get the id of that and find the last two characters for the chat ID. This presents some problems, as it would require rewrites if IDs changed lengths, and seems just plain inelegant to me. I then remembered the .data() facility in jQuery... I thought, maybe I could do it more like this: <input type="text" class="chattext"> ... and add a .data("id", 42) to this one <input type="button" class="chatsubmit"> ... and add a .data("id", 42) So that when they click chatsubmit, it gets the ID, and then finds the chattext with that ID and processes it. But looking at the documentation, I don't see an easy way to search by this. For example, let's say the event target in this case is the chatsubmit with the data('id') of 42... var ID = $(event.target).data('id'); // Sets it to 42 var chattext = ... And here I run into the trouble. How do I find which DOM element matches a class of chattext and a data('id') of 42? Is there any easy method, or do I have to search every .chattext for the one with an id of 42? Or is there another easy way of doing this? I did consider the possibility of the container div having the ID, which would make it, I think,? slightly easier to get. But if this works, it could be dealing with things in other container divs as well, making that not a long-term solution. Edit: Literally seconds after posting this, I found this: http://james.padolsey.com/javascript/extending-jquerys-selector-capabilities/ which includes information on extending the selector to data. So I'll try that out, and in the meantime, is this a completely foolhardy way of handling this?

  • How to check if a BOOL is null?

    - by Sheehan Alam
    Is there a way I can check to see if a value is NULL/Nil before assigning it to a BOOL? For example, I have a value in a NSDictionary that can be either TRUE/FALSE/NULL mySTUser.current_user_following = [[results objectForKey:@"current_user_following"]boolValue]; When the value is NULL I get the following error *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSNull boolValue]: unrecognized selector sent to instance I would like to be able to handle the NULL case.

  • Overriding jQuery plugin methods, as default and for single instances

    - by Kilgore2k
    Hi, The basic question is: How do I perform a basic override of a plugin method without editing the original plugin file? Is it possible to create an override for a specific instance: Example: An rtf plugin uses: $('selector').wysiwyg('setContent',newContent); In order to display the rtf text as readonly I would like for the same method to be applied to a div instead of the body of the IFRAME I would like to overwrite the original 'setContent' with my own code, just for this one element. Thanks

  • SEL performSelector and arguments

    - by madmik3
    Hello, It seems like there should be an easy way to call a selector with some arguments when all you have is a SEL object. I can't seem to find the correct syntax. -(MyClass*) init: (SEL)sel owner:(NSObject*) parent { int i =10; [parent performSelector:sel:i ]; }

  • A viewmodel's role beyond databinding?

    - by DeanMc
    I'm a bit confused as to what a viewmodel's role is beyond databinding. I have a menu built in silverlight. The menu has x number of menu items which is determined at runtime. One of the features I would like to add to this is that each menuitem has a different text colour when hovered over. Is it the role of the view to have a colour selector method or should the view handle this in it's code behind?

  • Objective-C: iPad Crash When Screen Shot Button Clicked

    - by SeongHo
    OK, i am making a Coloring app and it has a "Save" button that will take the screen shot of the view where the drawing is. I have 6 images to color. In the intro page there 6 buttons, each will link you to a particular coloring page. All are working well including the "Save" button except for one. All coloring views has the same contents and functions but in one image, it crashes the iPad whenever i clicked the "Save" button. Here's some of my codes: On Button Click: [self saveScreenshotToPhotosAlbum]; camFlash = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)]; [camFlash setBackgroundColor:[UIColor whiteColor]]; [camFlash setAlpha:0.0]; [cbHolder addSubview:camFlash]; [cbHolder bringSubviewToFront:camFlash]; [UIView beginAnimations:@"Flash-On" context:NULL]; [UIView setAnimationDuration:0.2]; [UIView setAnimationRepeatAutoreverses:NO]; [camFlash setAlpha:1.0]; [UIView commitAnimations]; NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"flash" ofType:@"wav"]; AVAudioPlayer *flashSFX = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:NULL]; flashSFX.volume = 0.5; flashSFX.numberOfLoops = 0; self->camFlashSFX = flashSFX; if ([flashSFX currentTime] != 0) [flashSFX setCurrentTime:0]; [flashSFX play]; [self performSelector:@selector(removeFlash) withObject:nil afterDelay:0.2]; Remove Flash: - (void) removeFlash { [camFlash removeFromSuperview]; } For the screenshot: - (UIImage*)captureView { UIGraphicsBeginImageContext(CGSizeMake(1024, 768)); CGContextRef context = UIGraphicsGetCurrentContext(); [cbHolder.layer renderInContext:context]; UIImage *img = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return img; } - (void)saveScreenshotToPhotosAlbum { UIImageWriteToSavedPhotosAlbum([self captureView], nil, nil, nil); } This one is for the button that will show the coloring page: uc4 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"tpUncolored1.png"]]; [uc4 setUserInteractionEnabled:YES]; [uc4 setFrame:CGRectMake(0, 0, 1024, 768)]; [cbHolder addSubview:uc4]; clrd4 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"tpColored1.png"]]; [clrd4 setUserInteractionEnabled:YES]; [clrd4 setFrame:CGRectMake(0, 0, 1024, 768)]; [cbHolder addSubview:clrd4]; [UIView beginAnimations:@"fabe-out" context:NULL]; [UIView setAnimationDuration:1.5]; [clrd4 setAlpha:0.0]; [UIView commitAnimations]; [self performSelector:@selector(cb4) withObject:nil afterDelay:1.5];

  • NSString cannot be released

    - by Stanley
    Consider the following method and the caller code block. The method analyses a NSString and extracts a "http://" string which it passes out by reference as an auto release object. Without releasing g_scan_result, the program works as expected. But according to non-arc rules, g_scan_result should be released since a retain has been called against it. My question are : Why g_scan_result cannot be released ? Is there anything wrong the way g_scan_result is handled in the posted coding below ? Is it safe not to release g_scan_result as long as the program runs correctly and the XCode Memory Leak tool does not show leakage ? Which XCode profile tools should I look into to check and under which subtitle ? Hope somebody knowledgeable could help. - (long) analyse_scan_result :(NSString *)scan_result target_url :(NSString **)targ_url { NSLog (@" RES analyse string : %@", scan_result); NSRange range = [scan_result rangeOfString:@"http://" options:NSCaseInsensitiveSearch]; if (range.location == NSNotFound) { *targ_url = @""; NSLog(@"fnd string not found"); return 0; } NSString *sub_string = [scan_result substringFromIndex : range.location]; range = [sub_string rangeOfString : @" "]; if (range.location != NSNotFound) { sub_string = [sub_string substringToIndex : range.location]; } NSLog(@" FND sub_string = %@", sub_string); *targ_url = sub_string; return [*targ_url length]; } The following is the caller code block, also note that g_scan_result has been declared and initialized (on another source file) as : NSString *g_scan_result = nil; Please do send a comment or answer if you have suggestions or find possible errors in code posted here (or above). Xcode memory tools does not seem to show any memory leak. But it may be because I do not know where to look as am new to the memory tools. { long url_leng = [self analyse_scan_result:result target_url:&targ_url]; NSLog(@" TAR target_url = %@", targ_url); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Scanned Result" message:result delegate:g_alert_view_delegate cancelButtonTitle:@"OK" otherButtonTitles:nil]; if (url_leng) { // ****** The 3 commented off statements // ****** cannot be added without causing // ****** a crash after a few scan result // ****** cycles. // ****** NSString *t_url; if (g_system_status.language_code == 0) [alert addButtonWithTitle : @"Open"]; else if (g_system_status.language_code == 1) [alert addButtonWithTitle : @"Abrir"]; else [alert addButtonWithTitle : @"Open"]; // ****** t_url = g_scan_result; g_scan_result = [targ_url retain]; // ****** [t_url release]; } targ_url = nil; [alert show]; [alert release]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(activate_qr_scanner:) userInfo:nil repeats:NO ]; return; }

  • UIButton does not respond to touch events after changing its position using setFrame

    - by Pranathi
    I have a view controller class (child) which extends from view controller class (parent). In the parent class's loadView() method I create a sub-view (named myButtonView) with two buttons (buttons are horizontally laid out in the subview) and add it to the main view. In the subclass I need to shift these two buttons up by 50pixels. So, I am shifting the buttonView by calling the setFrame method. This makes the buttons shift and render properly but they do not respond to touch events after this. Buttons work properly in the views of Parent class type. In the child class type view also, if I comment out the setFrame() call the buttons work properly. How can I shift the buttons and still make them respond to touch events? Any help is appreciated. Following is snippets of the code. In the parent class: - (void)loadView { // Some code... CGRect buttonFrameRect = CGRectMake(0,yOffset+1,screenRect.size.width,KButtonViewHeight); myButtonView = [[UIView alloc]initWithFrame:buttonFrameRect]; myButtonView.backgroundColor = [UIColor clearColor]; [self.view addSubview:myButtonView]; // some code... CGRect nxtButtonRect = CGRectMake(screenRect.size.width - 110, 5, 100, 40); myNxtButton = [UIButton buttonWithType:UIButtonTypeCustom]; [myNxtButton setTitle:@"Submit" forState:UIControlStateNormal]; myNxtButton.frame = nxtButtonRect; myNxtButton.backgroundColor = [UIColor clearColor]; [myNxtButton addTarget:self action:@selector(nextButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; [myButtonView addSubview:myNxtButton]; CGRect backButtonRect = CGRectMake(10, 5, 100, 40); myBackButton = [UIButton buttonWithType:UIButtonTypeCustom]; [myBackButton setTitle:@"Back" forState:UIControlStateNormal]; myBackButton.frame = backButtonRect; myBackButton.backgroundColor = [UIColor clearColor]; [myBackButton addTarget:self action:@selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; [myButtonView addSubview:myBackButton]; // Some code... } In the child class: - (void)loadView { [super loadView]; //Some code .. CGRect buttonViewRect = myButtonView.frame; buttonViewRect.origin.y = yOffset; // This is basically original yOffset + 50 [myButtonView setFrame:buttonViewRect]; yOffset += KButtonViewHeight; // Add some other view below myButtonView .. }

  • iOS dynamic object creation

    - by Abdul Ahmad
    I've worked with Xcode and iOS on a few personal projects and have always used non-object-oriented designs for everything... just because I've been doing mostly learning/experimenting with things. Now I've been trying to implement some object oriented design into one game I've made previously. The idea is, I have a space ship that can shoot bullets. In the past I basically added the UIImageView to the storyboard and then connected it to the .h file and from there did things on it like move it around or whatever (using CGPointMake). The idea now is to make a method (and a whole other class soon) that will create a UIImageView programmatically, allocate it, add it to the superview etc... I've got this working so far, easy stuff, but the next part is a bit harder. Where do I store this local variable "bullet"? I've been saving it to an NSMutableArray and doing the following: (actually here are the methods that I have) -(void)movement { for (int i = 0; i < [array1 count]; i ++) { UIImageView *a = [array1 objectAtIndex:i]; a.center = CGPointMake(a.center.x + 2, a.center.y); if (a.center.x > 500) { [array1 removeObjectAtIndex:i]; [a removeFromSuperview]; } } } -(void)getBullet { UIImageView *bullet = [[UIImageView alloc] initWithFrame:CGRectMake(ship.center.x + 20, ship.center.y - 2, 15, 3)]; bullet.image = [UIImage imageNamed:@"bullet2.png"]; bullet.hidden = NO; [self.view addSubview:bullet]; [array1 addObject:bullet]; } (by the way, array1 is declared in the .h file) and theres a timer that controls the movement method timer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(movement) userInfo:nil repeats:YES]; first question is: what is the correct way of doing this? Storing a bullet for example until it is removed from the superview, should I store it another way? and another question is, when I remove a UIImageView from the superview, does that remove it from memory so its not using up system resources? Thank you for the help! (will update if I Think of other questions
