CCSprite引發的異常spriteWithSpriteFrameName

Question

我正在嘗試創建一個動畫sprite類，該類有啓動和停止動畫的方法。當我將CCSprite變量從本地移動到伊娃時，該類將引發異常。通過將CCSprite變量作爲本地變量，類工作，即精靈出現並被動畫化。

該項目啓用ARC，所有coocs2d文件都標記爲-fno-objc-arc。我使用TexturePacker創建底層文件，但我認爲這與這個問題沒有任何關係。

我在做什麼錯？

cocos2D上版本2.01.00 的Xcode 4.6.2版

如何類被稱爲：

CCSpriteBatchNode *animatedSprite = [[AnimatedSprite alloc] init]; 
animatedSprite.position = ccp(winSize.width/2, winSize.height/2); 
[self addChild:animatedSprite]; 

類的頭

#import <Foundation/Foundation.h> 
#import "cocos2d.h" 

@interface AnimatedSprite : CCSpriteBatchNode 
{ 
} 

@end 

類的作品

#import "AnimatedSprite.h" 

@interface AnimatedSprite() 
{ 
    CCAction *action; 
// CCSprite *sprite; 
} 

@end 

@implementation AnimatedSprite 

- (id)init 
{ 
    if (self = [super init]) 
    { 
     [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"spriteSheet.plist"]; 
     self = [CCSpriteBatchNode batchNodeWithFile:@"spriteSheet.png"]; 

     NSMutableArray *animatedFrames = [NSMutableArray array]; 
     for (int i=1; i<=4; i++) 
     { 
      [animatedFrames addObject: 
      [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: 
       [NSString stringWithFormat:@"sprite%d.png",i]]]; 
     } 
     CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:@"sprite1.png"]; 
//  sprite = [CCSprite spriteWithSpriteFrameName:@"sprite1.png"]; 
     CCAnimation *animation = [CCAnimation animationWithSpriteFrames:animatedFrames delay:0.1f]; 
     action = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:animation]]; 
     [sprite runAction:action]; 
     [self addChild:sprite]; 
    } 
    return self; 
} 

@end 

類拋出異常

#import "AnimatedSprite.h" 

@interface AnimatedSprite() 
{ 
    CCAction *action; 
    CCSprite *sprite; 
} 

@end 

@implementation AnimatedSprite 

- (id)init 
{ 
    if (self = [super init]) 
    { 
     [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"spriteSheet.plist"]; 
     self = [CCSpriteBatchNode batchNodeWithFile:@"spriteSheet.png"]; 

     NSMutableArray *animatedFrames = [NSMutableArray array]; 
     for (int i=1; i<=4; i++) 
     { 
      [animatedFrames addObject: 
       [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: 
       [NSString stringWithFormat:@"sprite%d.png",i]]]; 
     } 
//  CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:@"sprite1.png"]; 
     sprite = [CCSprite spriteWithSpriteFrameName:@"sprite1.png"]; 
     CCAnimation *animation = [CCAnimation animationWithSpriteFrames:animatedFrames delay:0.1f]; 
     action = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:animation]]; 
     [sprite runAction:action]; 
     [self addChild:sprite]; 
    } 
    return self; 
} 

@end

爲什麼你想創建一個類，做精靈動畫？已經有很多事情可以爲你工作。看看sprite and level helper.他們自動爲你做動畫。沒有必要重塑一些已經爲你準備的東西:)
