SneakyInput/SneakyButton

Question

我目前正在試驗各種輸入控件，並且偶然發現了SneakyInput，我正在嘗試使用它。

不幸的是，當我加入一個SneakyButton（只是一個按鈕）層，並出現以下錯誤消息在整個應用程序崩潰：

+[CCTouchDispatcher addTargetedDelegate:priority:swallowsTouches:]: unrecognized selector sent to class 0xfed9c 2012-01-30 10:00:50.881 OpenSpace[588:1be03] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[CCTouchDispatcher addTargetedDelegate:priority:swallowsTouches:]: unrecognized selector sent to class 0xfed9c'

我已經撞了我的頭周圍這幾個小時並試圖以很少的喜悅Google解決方案。任何幫助在這裏將不勝感激，爲什麼，它爲什麼會崩潰？

環境：2.0的cocos2d-β，OS X 10.7.2，iOS的5.0

代碼：

-(void) addFireButton { 
float buttonRadius = 80; 
CGSize screenSize = [[CCDirector sharedDirector] winSize]; 

fireButton = [[[SneakyButton alloc] initWithRect:CGRectZero] autorelease]; 
fireButton.radius = buttonRadius; 
fireButton.position = CGPointMake(screenSize.width - buttonRadius, buttonRadius); 
[self addChild:fireButton]; 
} 

錯誤消息完整：

Answer 1

我終於設法解決了這個問題，對於那些感興趣的解決方案是將CCTouchDispatcher的所有引用替換爲CCDirector的屬性。在cocos2d 2.0版中，CCTouchDispatcher不再是單例，而是CCDirector的一個屬性。

我已付出github上SneakyInput庫並直接加入我的修正有

Answer 2

SneakyInput是爲Cocos2D中v0.99書面/1.0。它可能不適用於Cocos2D 2.0，因爲CCTouchDispatcher的API可能已更改。至少這就是錯誤消息所說的，CCTouchDispatcher上沒有這樣的方法addTargetedDelegate:priority:swallowsTouches:。

除非您需要或想要使用着色器程序，否則我會建議暫時使用Cocos2D v1.x。 SneakyInput與v1.x很好地工作
