  • Adding the scrollview created by photoscroller to a subview

    - by wierddemon
    I'm trying to modify Apple's PhotoScroller example to make the scrollview that is created into a subview instead of it being a view that takes up the entire screen. Any ideas on how this can be accomplished? - (void)loadView { // Step 1: make the outer paging scroll view CGRect pagingScrollViewFrame = [self frameForPagingScrollView]; pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame]; pagingScrollView.pagingEnabled = YES; pagingScrollView.backgroundColor = [UIColor blackColor]; pagingScrollView.showsVerticalScrollIndicator = NO; pagingScrollView.showsHorizontalScrollIndicator = NO; pagingScrollView.contentSize = [self contentSizeForPagingScrollView]; pagingScrollView.delegate = self; // When I do this it fails [self.view addSubview:pagingScrollView]; // Step 2: prepare to tile content recycledPages = [[NSMutableSet alloc] init]; visiblePages = [[NSMutableSet alloc] init]; [self tilePages]; }

  • Wrong class type in objective C

    - by Max Hui
    I have a parent class and a child class. GameObjectBase (parent) GameObjectPlayer(child). When I override a method in Child class and call it using [myPlayerClass showNextFrame] It is calling the parent class one. It turns out in the debugger, I see the myPlayerClass was indeed class type GameObjectBase (which is the parent class) How come? GameObjectBase.h #import <Foundation/Foundation.h> #import "cocos2d.h" @class GameLayer; @interface GameObjectBase : NSObject { /* CCSprite *gameObjectSprite; // Sprite representing this game object GameLayer *parentGameLayer; */ // Reference of the game layer this object // belongs to } @property (nonatomic, assign) CCSprite *gameObjectSprite; @property (nonatomic, assign) GameLayer *parentGameLayer; // Class method. Autorelease + (id) initWithGameLayer:(GameLayer *) gamelayer imageFileName:(NSString *) fileName; // "Virtual methods" that the derived class should implement. // If not implemented, this method will be called and Assert game - (void) update: (ccTime) dt; - (void) showNextFrame; @end GameObjectPlayer.h #import <Foundation/Foundation.h> #import "GameObjectBase.h" @interface GameObjectPlayer : GameObjectBase { int direction; } @property (nonatomic) int direction; @end GameLayer.h #import "cocos2d.h" #import "GameObjectPlayer.h" @interface GameLayer : CCLayer { } // returns a CCScene that contains the GameLayer as the only child +(CCScene *) scene; @property (nonatomic, strong) GameObjectPlayer *player; @end When I call examine in debugger what type "temp" is in this function inside GameLayer class, it's giving parent class GameObjectBase instead of subclass GameObjectPlayer - (void) update:(ccTime) dt { GameObjectPlayer *temp = _player; [temp showNextFrame]; }

  • Looking for some help working with premultiplied alpha

    - by user315142
    I am trying to update a source image with the contents of multiple destination images. From what I can tell using premultiplied alpha is the way to go with this, but I think I am doing something wrong (function below). the image I am starting with is initialized with all ARGB values set to 0. When I run the function once the resulting image looks great, but when I start compositing on any others all the pixels that have alpha information get really messed up. Does anyone know if I am doing something glaringly wrong or if there is something extra I need to do to modify the color values? void CompositeImage(unsigned char *src, unsigned char *dest, int srcW, int srcH){ int w = srcW; int h = srcH; int px0; int px1; int px2; int px3; int inverseAlpha; int r; int g; int b; int a; int y; int x; for (y = 0; y < h; y++) { for (x= 0; x< w*4; x+=4) { // pixel number px0 = (y*w*4) + x; px1 = (y*w*4) + (x+1); px2 = (y*w*4) + (x+2); px3 = (y*w*4) + (x+3); inverseAlpha = 1 - src[px3]; // create new values r = src[px0] + inverseAlpha * dest[px0]; g = src[px1] + inverseAlpha * dest[px1]; b = src[px2] + inverseAlpha * dest[px2]; a = src[px3] + inverseAlpha * dest[px3]; // update destination image dest[px0] = r; dest[px1] = g; dest[px2] = b; dest[px3] = a; } } }

  • Validate NSString

    - by Chris
    I am validating an NSString to ensure that the string does not contain apostrophes. The code I'm using to do this is NSCharacterSet * invalidNumberSet = [NSCharacterSet characterSetWithCharactersInString:@"'"]; NSScanner * scanner = [NSScanner scannerWithString:string]; NSString * scannerResult; [scanner setCharactersToBeSkipped:nil]; [scanner scanUpToCharactersFromSet:invalidNumberSet intoString:&scannerResult]; if(![string isEqualToString:scannerResult]) { return 2; } Returning 2 represents an error. This code works, except for the case where the string is an apostrophe. To get around this issue, I added the following code above the preceding block. if([string isEqualToString:@"'"]); { return 2; } This code is evaluating to true, regardless of the input. I need to either prevent the first block from crashing with the input of ', or get the second block to work. What am I missing?

  • Can I use Google Drive's editor interface embed in a website?

    - by Zamith
    I want to use google drive to store the files, but allow the users of my website to be able to edit them transparently, so that they don't have to go to google drive's website. Is this possible with the current API? Thus far I have only seen how to create an app for them to install in google drive, or doing something like DrEdit (https://developers.google.com/drive/examples/), which parses the files to JSON and uses the ACE editor, which is definitely not what I want.

  • How to create a NSPredicate to find entries with leading numerical value?

    - by Toastor
    Hello, I'm using NSPredicates to fetch entities based on a name attribute. Creating a predicate for names beginning with letters was easy (@"name BEGINSWITH %@", searchLetter), however now I'd like to fetch all entities with a name that begins with a numerical value, or rather a non-alphabetical number. What would be the appropriate predicate expression here? Right now I don't want to get too deep into predicate programming, as this is all I need right now and time flies. So, please, don't point me to the Predicate Programming Guide, I just need that expression.. :) Thanks alot guys!

  • Xcode save image to camera roll

    - by user1470914
    I am new to Xcode (using 4.3) and am not sure how to save an image to the device's camera roll. All that I have done so far is an IBAction for the button to save the image (the button resides in the top right of the navigation bar. This tutorial (http://www.youtube.com/watch?v=sSdwjQUXA2Y) is EXACTLY what I would like to be able to do but the code is too blurry to read properly. Any help would be greatly appreciated.

  • memory management question -- releasing an object which has to be returned

    - by ulag
    Hi, I have an NSMutableArray called playlist. This is in a method called getAllPlaylists. The code is something like this: -(NSMutableArray *)getAllPlaylists { //playlist is an instance variable playlist = [[NSMutableArray alloc] init]; //memory leak here . . //some code here which populates the playlist array [playlist addObject: object1]; . . return playlist; } The array allocation step of playlist is causing a memory leak. In such a scenario where can i release this array? Or can i avoid allocation n initialization of playlist here by doing something else?

  • Setting up an independent delegate?

    - by fuzzygoat
    Its common for the dataSource and delegate to be the same object, its also common for this object to be the viewController. In all the info/tutorials that I have seen online delegates are always setup as above. If I wanted to create my own class instead can anyone give me any pointers as to how I might do that. Where does that object get instantiated, how do you connect the dataSource and delegate items etc. I am using UITableView to test this.

  • What kind of data type is this?

    - by mystify
    In an class header I have seen something like this: enum { kAudioSessionProperty_PreferredHardwareSampleRate = 'hwsr', // Float64 kAudioSessionProperty_PreferredHardwareIOBufferDuration = 'iobd' // Float32 }; Now I wonder what data type such an kAudioSessionProperty_PreferredHardwareSampleRate actually is? I mean this looks like plain old C, but in Objective-C I would write @"hwsr" if I wanted to make it a string. I want to pass such an "constant" or "enum thing" as argument to an method.

  • What options I have to show a sentence parts with different color?

    - by Pentium10
    I have a longer sentence 200 characters. I need to show on the screen having parts of them in different color, like highlighting search results, each with different color. The text should auto wrap with screen width, and have no break sections between parts. I meant with this that I can put sections on a new line. They will have to continue the previous section, only wrap when the screen is off. The best would be an EditText, as I need to allow editing also, but I am wondering I am able to change the color of various sentence parts, or just as a whole. What do you think, with what UI elements can I achieve this view?

  • Configure UIDatePicker with current locations time

    - by Telkitty
    I am using UIDatePicker in my current app, here is how I set a UILabel with the date time string obtained from the UIDatePicker. -(IBAction)AddTimeEnd:(id)sender { NSDate * date = [m_DateTimePicker date]; m_DateTimeLabel.text = [date description]; } Somehow the time I have entered (EST) kept on getting converted to US time in the UILabel. Does anyone know how to fix it? I would like the time entered in UIDatePicker to be consistent with the text in the label (probably the simplest way is set the locale for the UIDatePicker to be the local timezone)?

    - by Fasttracks
    I have 1 scrollview that contain 18 buttons. 1) when a user taps on any button, a button is added to a second UIScrollView. 2) Then, when a user taps on that button on second scrollview the button is removed from second scrollview. both uiscrollviews contain a list of their buttons. Afree both of these steps, I have to reload my scrollview. Can I do the same task by adding observer, so that it will automatically reload when any action done on button, and if yes then how?
