I am trying to change the color of a CCLayerColor called bgColorLayer, however when I check to see if it is initialized it returns null. I have a color picker that calls the setBGColor: method. I know the colorpicker is calling the method and it is spitting out the correct colors. I am just at a loss as to why the bgColorLayer is null.
This is Cocos2D for Mac.
Any thoughts on why?
In my AppDelegeate method I have an IBOUTLET that is is tied to the NSColorWell
- (IBAction)colorwellBackground:(id)sender {
NSLog(#"Color Well: %#", [sender color]);
// Yes I know the sender color isn’t passing the correct value
AnimationViewerLayer * bkg = [AnimationViewerLayer alloc];
[bkg setBGColor:[sender color]];
}
AnimationViewerLayer.h
#interface AnimationViewerLayer : CCLayer
{
CCLayerColor * bgColorLayer;
}
+ (CCScene *) scene;
#end
AnimationViewLayer.m
#import "AnimationViewerLayer.h"
#implementation AnimationViewerLayer
+(CCScene *) scene
{
CCScene *scene = [CCScene node];
AnimationViewerLayer *layer = [AnimationViewerLayer node];
[scene addChild: layer];
return scene;
}
-(id) init
{
if( (self=[super init])) {
float red = 25.0 * 255;
bgColorLayer = [CCLayerColor layerWithColor:ccc4(57, 109, 58, 255)];
[self addChild:bgColorLayer z:1];
}
return self;
}
- (void) setBGColor: (ccColor3B) color{
NSLog(#"SET BG COLOR");
[bgColorLayer setColor:ccRED];
}
- (void) dealloc {
[super dealloc];
}

I am creating progress view by using CALayer by following
Header class
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#interface ProgressBar : UIView
#property (strong, nonatomic) CALayer *subLayer;
#property (nonatomic) CGFloat progress;
#end
Implementation class
#implementation ProgressBar
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
self.progress = 0;
self.backgroundColor = [UIColor whiteColor];
self.subLayer = [CALayer layer];
self.subLayer.frame = self.bounds;
self.subLayer.backgroundColor = [UIColor orangeColor].CGColor;
[self.layer addSublayer:self.subLayer];
}
return self;
}
- (void)setProgress:(CGFloat)value {
NSLog(#"what is going on here");
if (self.progress != value) {
self.progress = value;
[self setNeedsLayout];
}
}
- (void)layoutSubviews {
CGRect rect = [self.subLayer frame];
rect.size.width = CGRectGetWidth([self bounds]) * self.progress;
[self.subLayer setFrame:rect];
}
In my viewcontroller, I am doing
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.pBar = [[ProgressBar alloc] initWithFrame:CGRectMake(0, 50, 320, 10)];
[self.view addSubview:self.pBar];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)click:(id)sender {
[self.pBar setProgress:.8];
}
When (IBAction)click is fired, I am getting into the infinitive loop like the picture below
Does anyone know what I am getting into this loop. Please advice me on this issue. Thanks
The problem is that your setProgress: method calls the setProgress: method - recursion.
- (void)setProgress:(CGFloat)value {
NSLog(#"what is going on here");
if (self.progress != value) {
self.progress = value; // <-- This calls [self setProgress:value]
[self setNeedsLayout];
}
}
Change the bad line to:
_progress = value;
Setting the ivar directly is always required when you implement the setter method of a property.
I want to implement iAd in my viewController so that i created the singleton class for iAd here the code that i used but it doesnt display iAd in my viewController.

}
This is how i implemented the singleton class for iAd when i excute this i didnt get iAd displayed over my ViewController.
If anyone know how to implement this please help me to get out of this issue. Thanks in Advance.
I have a custom view that I'm using in a xib file. I load the view and add it to a window. It adds the view just fine as I can see the default text of the labels in the view, but when I try to change the label with a method call, it doesn't change the text.
The custom view isn't anything to fancy, just draws a rounded, transparent background.
NotificationView.h
#import <Cocoa/Cocoa.h>
#interface NotificationView : NSView
#property (weak) IBOutlet NSTextField *primaryLabel;
#property (weak) IBOutlet NSTextField *secondaryLabel;
#property (weak) IBOutlet NSTextField *identifierLabel;

#implementation NotificationView
#synthesize primaryLabel;
#synthesize secondaryLabel;
#synthesize identifierLabel;

self = [super initWithFrame:frameRect];
if (self)

NSColor *bgColor = [NSColor colorWithCalibratedWhite:0.0 alpha:0.6];
NSRect rect = NSMakeRect([self bounds].origin.x + 3, [self bounds].origin.y + 3, [self bounds].size.width - 6, [self bounds].size.height - 6);
NSBezierPath *path = [NSBezierPath bezierPathWithRoundedRect:rect xRadius:5.0 yRadius:5.0];
[path addClip];
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor:[NSColor redColor]];
[shadow setShadowBlurRadius:2.0f];
[shadow setShadowOffset:NSMakeSize(0.f, -1.f)];
[shadow set];
[bgColor set];
NSRectFill(rect);
[super drawRect:dirtyRect];
}

In the xib I have a custom view set to the type NotificationView. I've added 3 labels to the view and connected them to the above IBOutlets. (I ctrl-click & drag from the label to the .h file to make the connection.)
I'm loading the view and adding it to a window with the following method. It looks through an array of windows, if an existing match is found it used that window, if not it creates a new window.
- (void) popupNotificationWithTag:(NSString *)tag fade:(double)msFade lineOne:(NSString *)lineOneText lineTwo:(NSString *)lineTwoText
{
NotificationWindow *notificationWindow;
NotificationWindow *tmpWindow;
NSEnumerator *enumerator;
// Walk the notification windows in the array
enumerator = [self.notificationWindows objectEnumerator];
if(enumerator)
{
while((tmpWindow = [enumerator nextObject]))
{
if([tmpWindow.tag isEqualToString:tag])
{
notificationWindow = tmpWindow;
}
}
}
// Make a new notification window
if (!notificationWindow)
{
int width = [[NSScreen mainScreen] frame].size.width;
int height = [[NSScreen mainScreen] frame].size.height;
notificationWindow = [[NotificationWindow alloc] initWithRect:NSMakeRect(width - 420, height - 130, 400, 100)];
NSNib *nib = [[NSNib alloc] initWithNibNamed:#"Notification" bundle: nil];
NSArray *objects;
[nib instantiateNibWithOwner:self topLevelObjects:&objects];
for (id obj in objects) {
if ([[obj class] isSubclassOfClass:[NSView class]])
[notificationWindow setContentView:obj];
}
[notificationWindow setTag:tag];
[self.notificationWindows addObject:notificationWindow];
}
// Display window
[notificationWindow makeKeyAndOrderFront:nil];
[notificationWindow display];
notificationWindow.fadeOut = msFade;
[notificationWindow setPrimaryText:lineOneText];
[notificationWindow setSecondaryText:lineTwoText];
[notificationWindow setIdentifierText:tag];
}

So I assume I'm doing something wrong connecting the labels to the IBOutlets, but I can't figure out what. I suppose I could create the view in code, but I was trying to be good and use the interface builder.
I'm in XCode 4.2.1.
I followed tutorial from cocos2d official site . I try to create some items for a menu when creating them i pass a selector with one parameter. For each item i pass different selector . I think here is the problem , but i dont see realy why here is the problem. My header file looks :
// When you import this file, you import all the cocos2d classes
#import "cocos2d.h"
#import "CCTouchDispatcher.h"
// HelloWorldLayer
#interface HelloWorldLayer : CCLayer {
CCSprite *first;
CCSprite *second;
}
// returns a CCScene that contains the HelloWorldLayer as the only child
+(CCScene *) scene;
- (void) setUpMenus;
- (void) doSomethingOne: (CCMenuItem *) menuItem;
- (void) doSomethingTwo: (CCMenuItem *) menuItem;
- (void) doSomethingThree: (CCMenuItem *) menuItem;
#end
Implementation file :
// Import the interfaces
#import "HelloWorldLayer.h"
// HelloWorldLayer implementation
#implementation HelloWorldLayer
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
- (void) doSomethingOne: (CCMenuItem *) menuItem
{
NSLog(#"The first menu was called");
}
- (void) doSomethingTwo: (CCMenuItem *) menuItem
{
NSLog(#"The second menu was called");
}
- (void) doSomethingThree: (CCMenuItem *) menuItem
{
NSLog(#"The third menu was called");
}
// on "init" you need to initialize your instance

first.position = ccp(100, 100);
[self addChild:first];
second = [CCSprite spriteWithFile:#"Icon.png"];
second.position = ccp(50, 50);
[self addChild:second];
[self schedule:#selector(nextFrame:)];
[self setUpMenus];
self.isTouchEnabled = YES;
}
return self;
}
- (void) registerWithTouchDispatcher {
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
}

You've got the same typo in all three menu item creation calls. You're telling the menu items that the selector they should use is called doSomenthing... (note the spurious n in the middle):
CCMenuItemImage *menuItem1 = [... selector:#selector(doSomenthingOne:)];
CCMenuItemImage *menuItem2 = [... selector:#selector(doSomenthingTwo:)];
CCMenuItemImage *menuItem3 = [... selector:#selector(doSomenthingThree:)];
but the actual names of your methods are doSomethingOne:, doSomethingTwo:, and doSomethingThree:.
The exact cause of the error message is that later, when the menu item needs to perform that selector, it will ask your class to tell it the method signature for the selector you gave it. Since you gave the item an incorrect selector, your class doesn't know the signature, and it returns nil. The menu item tries to construct an NSInvocation object anyways to perform its action, which fails because the invocation can't be created with a nil signature.
Fix the typos and everything should work fine.
I'm sure this is really obvious to someone, but this simple thing is really frustrating me.
I have a class I made called Class_Sprite, which is a sub-class of CCSprite.
I have a method in this class that is supposed to both create the texture for any given instance of Class_Sprite, and then move it to (200,200).
The program runs in the sim but all I get is a black screen.
I was able to render the sprite directly from the layer class.
Here are the files.
Class_Sprite:
#import "Class_Sprite.h"
#implementation Class_Sprite
-(id)init
{
if ((self = [super init]))
{
}
return self;
}
-(void)make:(id)sender
{
sender = [Class_Sprite spriteWithFile:#"Icon.png"];
[sender setPosition: ccp(200, 200)];
}
#end
Class Sprite header:
#import <Foundation/Foundation.h>
#import "cocos2d.h"
#interface Class_Sprite : CCSprite {
}
-(void)make:(id)sender;
#end
HelloWorldLayer.m (where the method is being called)
#implementation HelloWorldLayer
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
// on "init" you need to initialize your instance
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super" return value
if( (self = [super init])) {
Class_Sprite *pc = [[Class_Sprite alloc] init];
[pc make:self]; //here is where I call the "make" method
[self addChild:pc];
[pc release];
}
return self;
}
// on "dealloc" you need to release all your retained objects
- (void) dealloc
{
// in case you have something to dealloc, do it in this method
// in this particular example nothing needs to be released.
// cocos2d will automatically release all the children (Label)
// don't forget to call "super dealloc"
[super dealloc];
}
#end
And finally the header file for HelloWorldLayer
#import "cocos2d.h"
#import "Class_Sprite.h"
// HelloWorldLayer
#interface HelloWorldLayer : CCLayer
{
}
// returns a CCScene that contains the HelloWorldLayer as the only child
+(CCScene *) scene;
#end
Thanks for your time
Try changing to this in Class_Sprite.m:
#implementation Class_Sprite
-(id)init
{
if ((self = [super initWithFile:#"Icon.png"]))
{
}
return self;
}
-(void)make:(CCNode *)sender
{
[self setPosition: ccp(200, 200)];
[sender addChild:self];
}
#end
And use it in HelloWorldLayer as follows:
Class_Sprite *pc = [[Class_Sprite alloc] init];
[pc make:self];
[pc release];
