私はスパロー フレームワークを使い始めたばかりで、Gamua 自身による「The Big Sparrow Tutorial」に従っています。AppScaffold 1.3 を使用してチュートリアルの最初の部分にいますが、基本的なコードをコンパイルしようとすると、読み込み画面でハングし、SIGABRT エラーが発生します。
例外ブレークポイントを配置すると、AppScaffold の GameController.m (下部に表示) で停止しました。
mGame = [[Game alloc] initWithWidth:gameWidth height:gameHeight];
これも私の唯一の出力でした：
2012-07-30 07:19:54.787 AppScaffold[1682:10a03] -[Game initWithWidth:height:]: unrecognized selector sent to instance 0x7553980
(lldb)
ストックの AppScaffold を使用しています。変更したのは Game.m だけです。
これは私のゲームです.m:
@interface Game : SPSprite
@end
@implementation Game
{
@private
SPImage *mBackground;
SPImage *mBasket;
NSMutableArray *mEggs;
}
- (id)init
{
if((self = [super init]))
{
//load the background image first, add it to the display tree
//and keep it for later use
mBackground = [[SPImage alloc] initWithContentsOfFile:@"background.png"];
[self addChild:mBackground];
//load the image of the basket, add it to the display tree
//and keep it for later use
mBasket = [[SPImage alloc] initWithContentsOfFile:@"basket.png"];
[self addChild:mBasket];
//create a list that will hold the eggs,
//which we will add and remove repeatedly during the game
mEggs = [[NSMutableArray alloc] init];
}
return self;
}
- (void)dealloc
{
[mBackground release];
[mBasket release];
[mEggs release];
[super dealloc];
}
@end
私は基本的なトラブルシューティング戦術を使用するために最善を尽くしましたが、私は Obj-C と Sparrow に非常に慣れていないので、手を使うことができます :)
ありがとう
