ios - 使用未声明的标识符“CCJumpBy”

Question

这是我的代码

#import "Gameplay.h"
#import <CCActionInterval.h>

@implementation Gameplay {
    CCPhysicsNode *_physicsNode;
}

- (void)didLoadFromCCB {
    // tell this scene to accept touches
    self.userInteractionEnabled = TRUE;
}
 - (void)touchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
    [self jumpRunner];
}


-(void)jumpRunner {
    CCNode *spaceship = [CCBReader load:@"Runner"];

    id jump = [CCJumpBy actionWithDuration:1 position:ccp(100, 0)
                                height:50 jumps:1];
    [spaceship runAction:jump];
}

@end

告诉我
Use of undeclared identifier 'CCJumpBy'
如何解决此问题以使其正常工作？我不知道该怎么办。
提前感谢

导入cocos2d，您应该解决错误

#import "cocos2d.h"
