编辑 4：我在 CCSpriteFrameCache spriteFrameByName 方法中添加了一个断点，并且无法跨过以下步骤（我很清楚 spriteFrames 以某种方式从 CCSpriteFrameCache 中删除）：
编辑 3：在投票结束问题之前，请使用Cocos2d 2.0 和附加的文件和 plist 文件尝试下面的代码（EDIT2） 。
编辑 2：我创建了一个全新的 GameScene 测试类，所以你们都可以尝试这个问题。一旦动画开始重复，它就会崩溃。我也更新了标题。

EDIT2结束：
原始问题：
我得到：
-[CCSprite setTexture:], /Users/.../libs/cocos2d/CCSprite.m:934 中的断言失败
它肯定与batchNode有关，因为没有它它曾经可以工作......
我知道动画的精灵帧应该在同一个精灵表中，就是这样。我不知道如何解决这个问题，它必须与使用批处理节点有关。
//
// Navigator.h
@interface Navigator : CCLayer {

//Batch Nodes
@property(readwrite, nonatomic) CCSpriteBatchNode* batchNode;
// Navigator.m
@implementation Navigator
@synthesize batchNode;
+(id) scene {
CCScene *scene = [CCScene node];

CCSprite * test = [CCSprite spriteWithSpriteFrameName:@"emptyCircle0.png"];

}
编辑：我检查了 CCSprite setTexture 的源代码，这就是我所看到的。然而，控制台日志确实只说 NSAssert 而没有给出问题所在的日志消息。添加断点似乎使第一个 NSAssert 失败，但我不确定 100%，因为应用程序会立即转到此图像：
-(void) setTexture:(CCTexture2D*)texture
{
// If batchnode, then texture id should be the same
NSAssert( !batchNode_ || texture.name == batchNode_.texture.name , @"CCSprite: Batched sprites should use the same texture as the batchnode");
// accept texture==nil as argument
NSAssert( !texture || [texture isKindOfClass:[CCTexture2D class]], @"setTexture expects a CCTexture2D. Invalid argument");
if( ! batchNode_ && texture_ != texture ) {
[texture_ release];
texture_ = [texture retain];
[self updateBlendFunc];
}
}
