iphone - UIButtonでUISwipeGestureRecognizerを使用するにはどうすればよいですか？

Question

ジョイスティックとして使用したいUIボタンがあります。だから私は同じボタンにいくつかのジェスチャー認識機能を追加しようとしています。私は今私のコードにこれを持っています：

@implementation CUETutorialSixteenClusterRootController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:@"CUETutorialLandscapeClusterRootController" bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (id)init {
    self = [super init];
    if (self) {
        _leftInActiveView = [[NSMutableArray alloc] init];
        _rightInActiveViews = [[NSMutableArray alloc] init];
        _centerInActiveViews = [[NSMutableArray alloc]init];
        _centerActiveViews = [[NSMutableArray alloc]init];

        UIImageView * inActLeftView = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 82, 98)] autorelease];
        inActLeftView.image = [UIImage imageNamed:@"1-am-station_01.png"];
        [_leftInActiveView addObject:inActLeftView];


        UIImageView * inActRightView = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 82, 98)] autorelease];
        inActRightView.image = [UIImage imageNamed:@"1-am-station_03.png"];
        [_rightInActiveViews addObject:inActRightView];

        NSArray * imagesName = [NSArray arrayWithObjects:[UIImage imageNamed:@"1_start.png"],

これは私が今得ているエラーです：-[CUETutorialSixteenClusterRootController handleSwipeFrom:]:認識されないセレクターがインスタンス0x79b71b0に送信されました2012-03-28 13：25：55.724 CUETrainer [1788：11f03] *キャッチされない例外のためにアプリを終了します' NSInvalidArgumentException'、理由：'-[CUETutorialSixteenClusterRootController handleSwipeFrom:]:認識されないセレクターが送信されましたインスタンス0x79b71b0 '

しかし、実際には何もしていません。助けてください！！！！

ジェスチャレコグナイザのターゲットは、セレクタを実装するオブジェクトである必要があります。スワイプが発生したときに今起こっていることは、ジェスチャレコグナイザーが実行していることです[self.gestureReceiverButton handleSwipeFrom:recognizer]

あなたはおそらくこれが欲しいでしょう：

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

エラーはunrecognized selector sent to instance 0x79b71b0'、おそらく.hと.mの名前が異なることを示しています。

次のすべてのインスタンスを変更します。

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];

に

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];

問題が解決しました。に十分注意してください@selectors。このマクロに配置する内容は、コンパイラによって検証されません。コードコンプリートはこれに役立ちます。

また、1つのビューに4つのジェスチャ認識機能を追加しますが、1つで同じタスクを実行できます。次のように、ビットごとのOR演算子を使用して有効な方向を組み合わせることができます。

[recognizer setDirection:(UISwipeGestureRecognizerDirectionUp | UISwipeGestureRecognizerDirectionDown)];
