  • UIView remove itself from UIScrollView

    - by alex25
    Hi! Following Scenario: I have a = UIViewController A that contains a UIScrollView I have a second UIViewController "B" (amongst other things it contains a button) and add it to the ScrollView of A myView *mView = [[myView alloc] init]; [myScrollView addSubview:mView.view]; Is there a way that once the button is pressed that it(view) removes itself from the scrollview? I thought in the direction of setting the delegate of mView to "A" ?! But not sure how that should work in detail.... Any suggestions? Thanks!

  • How to check for an active Internet Connection on iPhone SDK?

    - by Brock Woolf
    I would like to check to see if I have an Internet connection on the iPhone using the Cocoa Touch libraries. I came up with a way to do this using an NSUrl. The way I did it seems a bit unreliable (because even Google could one day be down and relying on a 3rd party seems bad) and while I could check to see for a response from some other websites if Google didn't respond, it does seem wasteful and an unnecessary overhead on my application. - (BOOL) connectedToInternet { NSString *URLString = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]]; return ( URLString != NULL ) ? YES : NO; } Is what I have done bad? (Not to mention 'stringWithContentsOfURL' is deprecated in 3.0) And if so what is a better way to accomplish this?

  • Manipulating a NSTextField via AppleScript

    - by Garry
    A little side project I'm working on is a digital life assistant, much like project JARVIS. What I'm trying to do is speak to my mac, have my words translated to text and then have the text interpreted by my program. Currently, my app is very simple, consisting of a single window containing a single wrapped NSTextView. Using MacSpeech Dictate, When I say the custom command "Jeeves", MacSpeech ensures that my app is frontmost, highlights any text in the TextField and clears it, then presses the Return key to trigger the textDidEndEditing method of NSTextField. This is done via Applescript. MacSpeech then switches to dictation mode and the next sentence I say will appear in the NSTextField. What I can't figure out is how to signify that I have finished saying a command to my program. I could simply say another keyword like "execute" or something similar that would send an AppleScript return keystroke to my app (thereby triggering the textDidEndEditing event) but this is cumbersome. Is there a notification that happens when text is pasted into a NSTextField? Would a timer work that would fire after maybe three seconds once my program becomes frontmost (three seconds should be sufficient for me to say a command)? Thanks,

  • Custom CallOut not displayed correctly in ios6?

    - by balu
    As i want to implement the custom call out in the mkmapview i am using these classes CalloutMapAnnotationView.h and CalloutMapAnnotationView.m I have extracted these classes from the following links https://github.com/asalom/Custom-Map-Annotation-Callouts/blob/master/Classes/CalloutMapAnnotationView.h https://github.com/asalom/Custom-Map-Annotation-Callouts/blob/master/Classes/CalloutMapAnnotationView.m These work fine in ios5 but in ios6 when i am clicking on the call out the map view is moving and call out is not showing correctly as shown in the below figures while i was zooming also its not coming correctly i have tried several ways to get rid out of this problem by checking the version of os and tried to change the some of the methods in the classes but of not use. After implementing these in ios5 map view coming like this In Ios6 This one not coming properly as like in ios5. for example

  • Cocos2d - smooth sprite movement in tile map RPG

    - by Lendo92
    I've been working on a 2-D Gameboy style RPG for a while now, and the game logic is mostly all done so I'm starting to try to make things look good. One thing I've noticed is that the walking movement / screen movement is a little bit choppy. Technically, it should work fine, but either it seems to be having some quirks, either due to taking up a lot of processing power or just timing inconsistencies between moving the screen and moving the sprite. To move the sprite, once I know where I want to move it, I call: tempPos.y += 3*theHKMap.tileSize.width/5; id actionMove = [CCMoveTo actionWithDuration:0.1 position:tempPos]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(orientOneMove)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; [self setCenterOfScreen:position]; Then, in orientOneMove, I call: [self.guy setTexture:[[CCTextureCache sharedTextureCache] addImage:@"guysprite07.png"]]; //the walking picture-I change texture back at the end of the movement id actionMove = [CCMoveTo actionWithDuration:0.15 position:self.tempLocation2]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(toggleTouchEnabled)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; The code for the concurrently running setCenterOfScreen:position method is: id actionMove = [CCMoveTo actionWithDuration:0.25 position:difference]; [self runAction: [CCSequence actions:actionMove, nil, nil]]; So the setCenterOfScreen moves the camera in one clean move while the guy moving is chopped into two actions to animate it (which I believe might be inefficient.) It's hard to tell what is making the movement not perfectly clean from looking at it, but essentially the guy isn't always perfectly in the center of the screen -- during movement, he's often times a pixel or two off for an instant. Any ideas/ solutions?

  • MAAttachedWindow hide

    - by Montecorte
    I had the same problem that The-Kenny at this post but I fixed it adding the windowDidResignKey: method on the MAAttachedWindow.m, but now my problem is that when I click outside the StatusBar item keeps blue background and when I click another time on the status item it goes normally and I have to click a second time on it to show the window. I tried to add a method in the CustomView (the view of the status item) that do the same thing that te mouseDown method: - (void)mouseDown:(NSEvent *)event { NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} my method is: - (void)windowDidResignKey { NSLog(@"Resigned"); NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} I call this method in the windowDidResignKey that I have defined on MAAttachedWindow.m, but this method dont call correctly the toggleAttachedWindowAtPoint method, I dont know exactly why, it's only called when I click another time over the status item If anybody knows how to do that any help would be fine. Thank you so much :)

  • NSTableView - Trying to fit exactly 9 rows

    - by Justin808
    Hi, I'm trying to size the rows of a NSTableView to exactly 9 rows fit. I've tried [menuTableView setRowHeight:floor(menuRect.size.height / 9)]; and I've tried [menuTableView setRowHeight:(menuRect.size.height / 9)]; and [menuTableView setRowHeight:ceil(menuRect.size.height / 9)]; but all of them have the same issue, if I've selected row 0 then row 9 is clipped at the bottom and if I select row 9 then row 0 is clipped at the top. How can I set up a NSTableView to show 9 full rows so no matter what there is never a partial row visible? Thanks, edit: Yes menuRect is the frame for the menuTableView

  • Animating the drawing of a line

Also, the startTotalLine method doesn't affect the line. I want it to animate the the line drawing from right to left

  • Localizing other pages in Settings.bundle

    - by joneswah
    I have other pages within my app preferences which are stored as separate files within the settings.bundle. It has come time to localize my app and I can only seem to get the Root values to localize. I was wondering whether there was a trick? The following image shows that my second screen is stored within a file called "MyPrefs.plist" and I have created a corresponding named file "MyPrefs.strings" in the en.lproj directory. Mirroring the same naming and location as the Root.plist and Root.strings. The values with the Root.plist are converted as expected but not in the extra screen. Is there any trick to localizing secondary screens with the settings.bundle?

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?

  • Editing an UIImage

    - by wwrob
    I have an UIImage that I want to edit (say, make every second row of pixels black). Now I am aware of the functions that extract PNG or JPEG data from the image, but that's raw data and I have no idea how the png/jpeg files work. Is there a way I can extract the colour data from each pixel into an array? And then make a new UIImage using the data from the array?

  • How do I enable spell checking within an NSTextField?

    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. Thank you.

  • Using the system localizations on iPhone

    - by nevan
    I want to make a back button for a navigation controller with the title "Back" instead of the title of the previous controller. I'm using this code: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", @"Back") style:UIBarButtonItemStyleBordered target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; I'd like to be able to skip localizing the "Back" string in my app (since I can only localize it in a limited number of languages). If I give my navigation controller no title, the back button will be automatically localized into whatever the language the user has chosen, so the system has translations of "Back" in many languages. Is there a way to access the localizations that are already present in the system and use them myself? These are things like "Back", "Cancel", "Done" and so on, which show up when creating one of the standard system buttons.

  • How can I make my tableview enter editing mode?

    - by Jake
    Hi, for some reason I can't get my tableview to enter editing mode. It's a little harder than it might seem because I'm using some open source code to make a calendar (iCal esque) with a tableview under it, and it's not quite as straightforward as just using a regular tableview. Basically, I have two classes. One (let's say Class A) is a UIViewController and the other (Class B) is that viewController's datasource and tableview delegate. In Class B, I've implemented -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath; which works fine, but if I put an edit nav bar item in Class A (the view controller), nothing happens. Am I forgetting certain protocols, or certain special methods that I need to write? Thanks for any help, and apologies if I'm missing something, I'm just learning to work with other people's code.
