Cocos2d iphone Cocos2D-[CCSpriteFrame delayUnits]：发送到实例的无法识别的选择器

我遵循了联机指南（），但我的应用程序在运行时崩溃，出现以下错误：

2013-02-19 16:03:23.028 WhackAMole[3616:907] -[CCSpriteFrame
delayUnits]: unrecognized selector sent to instance 0x1f548ce0

如果添加异常断点，Xcode将暂停此函数（Cocos2D）中的代码执行：

顺便说一下，这是代码：

有人能帮我吗

先谢谢你

已解决

而不是使用：

return[cAnimation animationWithAnimationFrames:AnimationFrames delayPerUnit:delay loops:6]

    NSMutableArray *animFrames = [NSMutableArray array];

    if ([animPlist isEqual: @"hitAnim"])
    {
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_thump1.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_thump2.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_thump3.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_thump4.png"]];

        return [CCAnimation animationWithAnimationFrames:animFrames delayPerUnit:delay loops:6];
    }

    else
    {
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh1.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh2.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh3.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh2.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh3.png"]];
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mole_laugh1.png"]];

        return [CCAnimation animationWithAnimationFrames:animFrames delayPerUnit:delay loops:6];
    }

我决定使用：
[cAnimation animation with priteframes:animFrames delay:delay]

NSString *plistPath = [[NSBundle mainBundle] pathForResource:animPlist ofType:@"plist"];
    NSArray *animImages = [NSArray arrayWithContentsOfFile:plistPath];
    NSMutableArray *animFrames = [NSMutableArray array];

    for(NSString *animImage in animImages)
    {        
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:animImage]];
    }

    return [CCAnimation animationWithSpriteFrames:animFrames delay:delay]; //Here's the
                                                                           //main
                                                                           //difference

arrayOfAnimationFrames
至少包含一个
CCSpriteFrame
对象，但它应该只包含
CCAnimationFrame
对象

由于您没有显示填充
arrayOfAnimationFrames
的代码，因此我无法说明为什么会发生这种情况，但您肯定应该查看该代码。这可能很简单，因为在调用
addObject
时意外使用了错误的变量。我在函数中填充了ArrayFanImationFrames:-（cAnimation*）animationFromPlist:（NSString*））Animaplist delay:（float）delay，并在init方法中“调用”了它。您能修改我的代码吗？我不明白怎么了。
NSString *plistPath = [[NSBundle mainBundle] pathForResource:animPlist ofType:@"plist"];
    NSArray *animImages = [NSArray arrayWithContentsOfFile:plistPath];
    NSMutableArray *animFrames = [NSMutableArray array];

    for(NSString *animImage in animImages)
    {        
        [animFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:animImage]];
    }

    return [CCAnimation animationWithSpriteFrames:animFrames delay:delay]; //Here's the
                                                                           //main
                                                                           //difference
