  • NSDictionary, NSArray, NSSet and efficiency

    - by ryyst
    Hi, I've got a text file, with about 200,000 lines. Each line represents an object with multiple properties. I only search through one of the properties (the unique ID) of the objects. If the unique ID I'm looking for is the same as the current object's unique ID, I'm gonna read the rest of the object's values. Right now, each time I search for an object, I just read the whole text file line by line, create an object for each line and see if it's the object I'm looking for - which is basically the most inefficient way to do the search. I would like to read all those objects into memory, so I can later search through them more efficiently. The question is, what's the most efficient way to perform such a search? Is a 200,000-entries NSArray a good way to do this (I doubt it)? How about an NSSet? With an NSSet, is it possible to only search for one property of the objects? Thanks for any help! -- Ry

  • How do I draw the desktop on Mac OS X?

    - by Dominic Cooney
    I want to draw the desktop on Mac OS X (Snow Leopard). Specifically, I want to achieve the same effect as running: /System/Library/Frameworks/ScreenSaver.framework/Resources/ ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background (If you’re not near your computer, this displays the screensaver where you would normally see your desktop background.) I know how to make a window without a border (by subclassing NSWindow and overriding initWithContentRect:styleMask:backing:defer: to set the window style to NSBorderlessWindowMask) and without a shadow (setHasShadow:NO.) I know that I can call setLevel:kCGDesktopWindowLevel or kCGDesktopIconWindowLevel to put my window below other windows (see question 418791.) However this isn’t exactly what I want, because a window at this level is still on top of the desktop icons. I want to be on top of the desktop background, but below the icons. My view is opaque. If there is a technique that clobbers the desktop background, that is OK.

  • CoreData: managedObjectContext not being created

  • Getting random objects from an array, and if the objects are the same, get a new object.

    - by XcodeDev
    Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

  • iPhone SDK Nested For Loop performance

    - by Skeep
    Hi All, I have a NSArray of string id and a NSDictionary of NSDictionary objects. I am currently looping through the string id array to match the id value in the NSDictionary. There are around 200 NSDictionary objects and only 5 or so string ID. My current code is such: for (NSString *Str in aArr) { for (NSDictionary *a in apArr) { if ([a objectForKey:@"id"] == Str) { NSLog(@"Found!"); } } } The performance of the above code is really slow and I was wondering if there is a better way to do this?

  • How can I add sprite image from a set of sprites which have different properties for each sprite?

    - by srikanth rongali
    In my application one player and 10 targets are there. Each target appears one after the other (from target1 to target10). It's a shooting game. If we hit the first target then second target will come. The targets have properties like name, speedOfGunDraw, probability to hit the player, speedOfFire. What should I do to make them appear one after the other with these properties. I am using CCMenuItem for the target. I am using a sprite for the player. Please give me idea to do this. Thank You.

  • Can I create a UITableViewController that inherits from a custom subclass of UIViewController?

    - by prendio2
    I have common functionality that I need to access from all screens of my app: a right bar button item and associated action. So as not to repeat the code I would like to set this up in a custom UIViewController and have all my view controllers inherit from it. - (void)viewDidLoad { UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:@selector(lightsCamera)]; self.navigationItem.rightBarButtonItem = rightBarButton; } - (void)lightsCamera { … } However, I have a number of UITableViewControllers however and I would like to know if it is possible for them to inherit the functionality too?

  • iPhone: Tracking/Identifying individual touches

    - by FlorianZ
    I have a quick question regarding tracking touches on the iPhone and I seem to not be able to come to a conclusion on this, so any suggestions / ideas are greatly appreciated: I want to be able to track and identify touches on the iphone, ie. basically every touch has a starting position and a current/moved position. Touches are stored in a std::vector and they shall be removed from the container, once they ended. Their position shall be updated once they move, but I still want to keep track of where they initially started (gesture recognition). I am getting the touches from [event allTouches], thing is, the NSSet is unsorted and I seem not to be able to identify the touches that are already stored in the std::vector and refer to the touches in the NSSet (so I know which ones ended and shall be removed, or have been moved, etc.) Here is my code, which works perfectly with only one finger on the touch screen, of course, but with more than one, I do get unpredictable results... - (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) touchesCancelled:(NSSet*)touches withEvent:(UIEvent*)event { [self handleTouches:[event allTouches]]; } - (void) handleTouches:(NSSet*)allTouches { for(int i = 0; i < (int)[allTouches count]; ++i) { UITouch* touch = [[allTouches allObjects] objectAtIndex:i]; NSTimeInterval timestamp = [touch timestamp]; CGPoint currentLocation = [touch locationInView:self]; CGPoint previousLocation = [touch previousLocationInView:self]; if([touch phase] == UITouchPhaseBegan) { Finger finger; finger.start.x = currentLocation.x; finger.start.y = currentLocation.y; finger.end = finger.start; finger.hasMoved = false; finger.hasEnded = false; touchScreen->AddFinger(finger); } else if([touch phase] == UITouchPhaseEnded || [touch phase] == UITouchPhaseCancelled) { Finger& finger = touchScreen->GetFingerHandle(i); finger.hasEnded = true; } else if([touch phase] == UITouchPhaseMoved) { Finger& finger = touchScreen->GetFingerHandle(i); finger.end.x = currentLocation.x; finger.end.y = currentLocation.y; finger.hasMoved = true; } } touchScreen->RemoveEnded(); } Thanks!

  • Delete Drag and Drop Behavior of IKImageBrowserView

    - by PF1
    Hi Everyone: By default (it seems), IKImageBrowserView enables drag and drop to locations in the Finder. I would like to turn off this behavior but am unsure of how to do so. I was thinking that perhaps implementing the NSDraggingDestination protocol and overriding it could solve this, but so far it hasn't worked for me. Thanks for any help!

  • Delegate methods of NSTextField using NSNotification

    - by hekevintran
    I have an NSTokenField in a window. I am using it to store tags related to a Core Data object. Right now I have it set up such that I can add tags to the objects, but I cannot delete them. I need a delegate method on the NSTokenField that can let me know when the user has moved the focus out of the NSTokenField. Since NSTokenField is a subclass of NSTextField I figured that I could use its delegate methods. It has two that I think could be useful: - (void)textDidChange:(NSNotification *)aNotification - (void)textDidEndEditing:(NSNotification *)aNotification I set my controller class as the delegate of my NSTokenField and put both of these methods into my controller class. I put a basic NSLog into each of them and neither is triggered when I interact with the NSTokenField. I am guessing it has something to do with NSNotification. How do I activate these methods?

  • Switching textstorage of NSTextViews back and forth

    - by Jakob Dam Jensen
    I'm trying to make a feature in a product which gives the user the ability to split a textview into two. The way this is done is by removing the textview from it's superview, making a NSSplitView and adding the textview as well as a new NSTextView instance to this splitview. Lastly I make these two textviews share the same textstorage in order to make them share the same content. It works great. But the problem is when I want to make one of the two textviews change textstorage. The replaceTextStorage method in NSLayoutManager causes both NSTextView to change textStorage. The API documentation states: replaceTextStorage: All NSLayoutManager objects sharing the original NSTextStorage object then share the new one. This method makes all the adjustments necessary to keep these relationships intact, unlike setTextStorage:. So it makes sense that it would do this. But the question is how do I make it possible to have two (or more) textviews first share the same storage and after that having them using their own? I've tried replacing the layoutManager and even making new instances of NSTextViews but no luck... Any suggestions?

  • UITouch Events and Table Views

    - by Andy
    I'm working on a navigation-based iPhone-only app that serves two main purposes: One, to present data in a hierarchical view, allowing users to drill down and eventually edit said data, and, two, to all users to perform a default action when the table view cell is tapped. I now need to offer a small set of options tied to the same data; however, both the didSelectRowAtIndexPath: and accessoryButtonTappedForRowAtIndexPath: methods are obviously taken. So, my options seem to be to implement a double-tap method, wherein the small list of additional options would be presented after (you guessed it) a double-tap on said table row; or, preferably, a tap-and-hold method. From what I can tell, tap-and-hold seems like the way to go in SDK 4.0 - which does me no good right this red-hot minute. I decided to go with the double-tap option, but I'm having a little trouble. First and foremost, the touchesBegan:withEvent: method does not seem to be getting called at all; a breakpoint placed within the method is never called while the application runs, and the table view responds exactly as it did before I inserted the method (which is to say, it performs the default action): - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *aTouch = [touches anyObject]; if (aTouch.tapCount == 2) { [NSObject cancelPreviousPerformRequestsWithTarget:self]; } } Second, I don't really need to handle a single-tap - the didSelectRowAtIndexPath: method can handle the single-tap just fine. The double-tap is the funky one I want to handle. I suspect the answer is going to contain the phrase, "You can't have the table view handle the single-tap and the touchesBegan: method handle the double-tap. The touch handling methods have to handle all of them." I would really appreciate some guidance from some of you who've dealt with this issue. Thanks in advance.

  • Interface Builder Does Not Recognize Toolbar Buttons

    - by Sheehan Alam
    I created 4 UIButton's that are Custom and Plain in IB. I added a background image to them and then placed them onto my UIToolbar. I created IBActions and hooked up all of the buttons I did not create @property for the buttons, but 3/4 of them appear on my toolbar and they work. Why isnt my 4th button appearing? If I need to declare an @property for them, will it be a UIToolbarButtonItem or a UIButton?

  • Invoking external shell application through RubyCocoa

    - by Shyam
    Hi, How would I invoke an external application through the RubyCocoa bridge? I read something about NSTask, yet I have no idea how this should be translated in RubyCocoa. My goal is to have an IB_action to trigger a method which will run a terminal application with some parameters, i.e. ls -p $mydir, where mydir comes from an IB_outlet such as an Textfield. Any directions or help would be greatly appreciated!

  • Objective-C: Getting the True Class of Classes in Class Clusters

    - by TechZen
    Recently while trying to answer a questions here, I ran some test code to see how Xcode/gdb reported the class of instances in class clusters. (see below) In the past, I've expected to see something like: PrivateClusterClass:PublicSuperClass:NSObject Such as this (which still returns as expected): NSPathStore2:NSString:NSObject ... for a string created with +[NSString pathWithComponents:]. However, with NSSet and subclass the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { NSSet *s=[NSSet setWithObject:@"setWithObject"]; NSMutableSet *m=[NSMutableSet setWithCapacity:1]; [m addObject:@"Added String"]; NSMutableSet *n = [[NSMutableSet alloc] initWithCapacity:1]; [self showSuperClasses:s]; [self showSuperClasses:m]; [self showSuperClasses:n]; [self showSuperClasses:@"Steve"]; } - (void) showSuperClasses:(id) anObject{ Class cl = [anObject class]; NSString *classDescription = [cl description]; while ([cl superclass]) { cl = [cl superclass]; classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]]; } NSLog(@"%@ classes=%@",[anObject class], classDescription); } ... outputs: // NSSet *s NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *m NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *n NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject // NSString @"Steve" NSCFString classes=NSCFString:NSMutableString:NSString:NSObject The debugger shows the same class for all Set instances. I know that in the past the Set class cluster did not return like this. What has changed? (I suspect it is a change in the bridge from Core Foundation.) What class cluster report just a generic class e.g. NSCFSet and which report an actual subclass e.g. NSPathStore2? Most importantly, when debugging how do you determine the actual class of a NSSet cluster instance?

  • CALayer and Off-Screen Rendering

    - by Luke Mcneice
    I have a Paging UIScrollView with a contentSize large enough to hold a number of small UIScrollViews for zooming, The viewForZoomingInScrollView is a viewController that holds a CALayer for drawing a PDF page onto. This allows me to navigate through a PDF much like the ibooks PDF reader. The code that draws the PDF (Tiled Layers) is located in: - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx; And simply adding a 'page' to the visible screen calls this method automatically. When I change page there is some delay before all the tiles are drawn, even though the object (page) has already been created. What i want to be able to do is render the next page before the user scrolls to it, thus preventing the visible tiling effect. However, i have found that if the layer is located offscreen adding it to the scrollview doesn't call the drawLayer. Any Ideas/common gotchas here? I have tried: [viewController.view.layer setNeedsLayout]; [viewController.view.layer setNeedsDisplay]; NB: The fact that this is replicating the ibooks functionally is irrelevant within the context of the full app.

  • NSMutableArray Problem - iPhone

    - by David Schiefer
    Hi, I'm trying to get a UITableView to read it's data from a file. I've attempted it like this: NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory]; self.dataForTable = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName]; This compiles fine, but when saving something to the file in the following snippet, the file is not saved nor anything is written to the array: NSMutableDictionary*userDictionary; userDictionary = [[NSMutableDictionary alloc] init]; [userDictionary setObject:name.text forKey:@"name"]; [userDictionary setObject:email.text forKey:@"email"]; [userDictionary setObject:serial.text forKey:@"serial"]; [userDictionary setObject:notes.text forKey:@"notes"]; [userDictionary setObject:[NSNumber numberWithInt:[licenseType selectedRowInComponent:0]] forKey:@"license_type"]; [userDictionary setObject:[date date] forKey:@"date"]; [userDictionary setObject:[NSNumber numberWithBool:[paymentSwitch isOn]] forKey:@"payment"]; NSString*dirToSaveTo = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSString*fileName = [NSString stringWithFormat:@"%@.plist",name.text]; NSString*saveName = [dirToSaveTo stringByAppendingPathComponent:fileName]; [userDictionary writeToFile:saveName atomically:NO]; NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory]; [self.dataForTable addObject:name.text]; NSLog(@"%@",self.dataForTable); [self.dataForTable writeToFile:fullFileName atomically:YES]; The NSLog just returns (null). The *plist file is never written. What am I doing wrong?

  • Display NSWindow as Subview of NSView...

    - by Nano8Blazex
    I have an NSWindow that I want to display as part of another window. It has to be an NSWindow; I don't want to change it to an NSView or anything... I just don't because it involves accessing foreign nib files and the such. How should I accomplish this if possible? I was thinking along the lines of grabbing the view of the NSWindow and sticking it as the subview of another view in my main window... but I don't think this is possible. Is it?

  • How can I dismiss keyboard in iPhone OS 3.2 with text field in popover?

    - by Tom H
    I have several text fields in a custom uiviewcontroller subclass, which is displayed within a popover. The popover is displayed form a bar button. I want the keyboard to go down when the popover is dismissed (either by the user tapping the bar button again, or tapping outside the popover. From the view controller that displays the popover, when the popover is dismissed, in either of the 2 fashions, I call [optionsController dismissFirstResponder]; Optionscontroller is the uiviewcontroller subclass in the popover. Dismissfirstresponder is a method I defined: -(void)dsimissFirstResponder { [nameField resignFirstResponder]; [descriptionField resignFirstResponder]; [helpField resignFirstResponder]; } Those are three IBoutlets which I connected in the xib to the text fields. That doesn't work. Any help with this would be greatly appreciated.

  • Tinting iPhone application screen red

    - by btschumy
    I'm trying to place a red tint on all the screens of my iPhone application. I've experimented on a bitmap and found I get the effect I want by compositing a dark red color onto the screen image using Multiply (kCGBlendModeMultiply). So the question is how to efficiently do this in real time on the iPhone? One dumb way might be to grab a bitmap of the current screen, composite into the bitmap and then write the composited bitmap back to the screen. This seems like it would almost certainly be too slow. In addition, I need some way of knowing when part of the screen has been redrawn so I can update the tinting. I can almost get the effect I want by putting a red, translucent, fullscreen UIView above everything. That tints everything red within further intervention on my part, but the effect is much "muddier" than results from the composite. So do any wizards out there know of some mechanism I can use to automatically composite the red over the app in similar fashion to what the translucent red UIView does?
