我已经下载了ABC开源并将源代码转成cocos2d 1.01。现在我遇到了初始化 Sprite 子类的问题。（我的子类是@interface OrbSprite：CCSprite）
此代码是无限循环和较旧的 cocos2d 版本。
-(id) init {
self = [super init];
if (self)
{
[self initWithFile:@"bubble1.png"];
Animation *bub = [Animation animationWithName:@"bubble" delay:0 images:@"bubble1.png", @"bubble2.png", nil];
self.bubble = bub;
[bub release];
[self addAnimation:bubble];
Label *l = [[Label alloc] initWithString:@"" dimensions:CGSizeMake(45, 45) alignment:UITextAlignmentCenter
fontName:@"Arial Rounded MT Bold" fontSize:18];
self.label = l;
[l release];
}
return self; }
我搜索了一个解决方案，可以通过更改init方法的名称来解决。
-(id) initWithBubbleImage {
if ((self = [super initWithFile :@"bubble1.png"]))
{
NSLog(@"OrbSprite init in if self Method");
bubblea = [NSArray arrayWithObjects:@"bubble1.png",@"bubble2.png",nil];
bub = [CCAnimation animationWithFrames:bubblea delay:0 ];
[[CCAnimationCache sharedAnimationCache] addAnimation:bub name:@"bubbleAnim"];
self.bubble = bub;
[bub release];
label = [[CCLabelTTF alloc] initWithString:@"" dimensions:CGSizeMake(45, 45) alignment:UITextAlignmentCenter
fontName:@"Arial Rounded MT Bold" fontSize:18];
}
return self; }
？？？问题是，当已经更改初始化名称时，我在同一子类中的“ -(void) setLabelStr:(NSString ) str ”中发现 addChild: 在调试区域中出错.. " * * Assertion failure in -[OrbSprite addChild: ]”和“由于未捕获的异常‘NSInternalInconsistencyException’而终止应用程序，原因：‘参数必须为非零’”
这是同一子类中的方法
- (void) setLabelStr:(NSString *) str {
[label setString:str];
[self addChild:label];
[label setAnchorPoint:ccp(0, 13)]; }
任何人都请帮助我.......非常感谢。

我已经这样做了作为答复。但仍然不起作用 听到的是 .h 和 .m 代码
OrbSprite.h
这是代码
#import "cocos2d.h"
@interface OrbSprite : CCSprite
{
CCLabelTTF *label;
CCAnimation *bubble;
BOOL isBubble;
BOOL isHidden;
int order;
CCSequence *popSequence;
}
@property (nonatomic, retain) CCLabelTTF *label;
@property (nonatomic, retain) CCSequence *popSequence;
@property (nonatomic, retain) CCAnimation *bubble;
@property (nonatomic, retain) NSArray *bubblea;
@property (readwrite) BOOL isBubble;
@property (readwrite) BOOL isHidden;
@property (readwrite) int order;
-(id)initWithBubbleImage;
- (void) pop;
- (void) setLabelStr:(NSString *) str;
- (void) showBubble;
- (void) reset;
@end
OrbSprite.m
这是代码
#import "OrbSprite.h"
@implementation OrbSprite
@synthesize bubble;
@synthesize label;
@synthesize isBubble;
@synthesize isHidden;
@synthesize popSequence;
@synthesize order;
@synthesize bubblea;
-(id) initWithBubbleImage {
if ((self = [super initWithFile:@"bubble1.png"]))
{
bubblea = [NSArray arrayWithObjects:@"bubble1.png",@"bubble2.png",nil];
bubble= [CCAnimation animationWithFrames:bubblea delay:0 ];
[[CCAnimationCache sharedAnimationCache] addAnimation:bub name:@"bubbleAnim"];
label = [[CCLabelTTF alloc] initWithString:@"" dimensions:CGSizeMake(45, 45)
alignment:UITextAlignmentCenter fontName:@"Arial Rounded MT Bold" fontSize:18];
}
return self;
}
- (void) pop {
isBubble = NO;
popSequence = [CCSequence actions:[CCScaleTo actionWithDuration:.1 scale:.5],
[CCScaleTo actionWithDuration:.1 scale:2], [CCCallFunc actionWithTarget:self
selector:@selector(finishedPopSequence)], nil];
[self runAction:popSequence];
}
- (void) finishedPopSequence {
self.scale = 1;
[self setDisplayFrameWithAnimationName:@"bubble" index:0]; }
- (void) reset {
self.scale = 1;
[self setDisplayFrameWithAnimationName:@"bubble" index:0]; }
- (void)showBubble {
isBubble = YES;
[self removeChild:label cleanup:NO];
[self setDisplayFrameWithAnimationName:@"bubbleAnim" index:1];
self.scale = .5;
id Orbshowscale = [CCScaleTo actionWithDuration:1 scale:1.5];
id Orbshowscale2= [CCScaleTo actionWithDuration:.1 scale:1];
[self runAction:[CCSequence actions:Orbshowscale,Orbshowscale2 , nil]]; }
- (void) setLabelStr:(NSString *) str {
[label setString:str];
[self addChild:label]; //<<< *** Assertion failure in -[OrbSprite addChild:]
[label setAnchorPoint:ccp(0, 13)]; }
@end
我已经解决了过度发布问题..但它仍然不起作用..
也发现同样的问题是
***-[OrbSprite addChild:] 中的断言失败
***由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“参数必须为非零”
感谢所有善良的人...
