我正在尝试加载游戏的开始菜单,并且使用 CCMenuItemImage 添加了一个播放按钮。一切都很好。但是,当我尝试单击播放按钮时,我收到此错误消息。
013-08-18 13:38:46.091 PeevedPenguins-iOS [5169:c07] *由于未捕获的异常“NSInvalidArgumentException”而终止应用程序,原因:“-[StartMenuLayer]:无法识别的选择器发送到实例 0x9e5b400”
我不知道我做错了什么,因为我的选择器已经定义好了。请帮帮我?我一直在努力弄清楚为什么 Xcode 会这样做
@interface StartMenuLayer ()
@end
@implementation StartMenuLayer
-(id) init
{
if ((self = [super init]))
{
CCMenu *myMenu = [CCMenu menuWithItems: nil];
CCMenuItemImage *menuBackground = [CCMenuItemImage itemWithNormalImage:@"menu-background-hd.png" selectedImage:@"menu-background-hd.png" target:self selector:nil];
[myMenu addChild:menuBackground];
CCMenuItemImage *menuPlayButton = [CCMenuItemImage itemWithNormalImage:@"button-hd.png" selectedImage:@"button-hd.png" target:self selector:@selector(playGame:)];
menuPlayButton.position = ccp(0, 0);
[myMenu addChild:menuPlayButton];
CCMenuItemImage * menuItem3 = [CCMenuItemImage itemWithNormalImage:@"catapult-hd.png"
selectedImage: @"catapult-hd.png"
target:self
selector:@selector(doSomethingThree:)];
[myMenu addChild: menuItem3];
menuPlayButton.position = ccp(0,-83.5);
[self addChild:myMenu];
}
return self;
}
-(void) playGame:(CCMenuItem *)sender
{
// [[CCDirector sharedDirector] replaceScene: (CCScene*)[[GameLayer alloc] init]];
NSLog(@"Play the game!");
}
