我

我在自定义 scrollView 类的 initierScrollView 函数中生成了多个 UIView 对象。我标记了每个对象并将每个对象插入到 NSMutableArray 对象中。比我将 UIPanGestureRecognizer 与每个视图对象相关联。

    -(void)initierScrollView
    {
        int i;
        for (i=0; i<6; i++) {

            UIImage *image = [UIImage imageNamed:@"back.png"];
            UIImageView *bouton = [[UIImageView alloc] initWithImage:image];
            [bouton setTag:i];
            [bouton setFrame:CGRectMake(10+62*i,10,62,55)];
 classementBoutons = [[NSMutableArray alloc] initWithCapacity:40];
            [classementBoutons insertObject:bouton atIndex:i];
            bouton.userInteractionEnabled = YES;

            UIPanGestureRecognizer *recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanGesture:)];
            //recognizer.delegate = self; 
            [bouton addGestureRecognizer:recognizer];


            [self addSubview:bouton];
    }

现在我正在尝试通过选择通过 Gesture 移动的对象来重用这些对象。我尝试了从 NSMutableArray 中获取每个对象的方法（如头文件下定义的那样），但 Xcode 似乎无法识别它们（没有新动作）。

-(IBAction)handlePanGesture:(UIPanGestureRecognizer*)recognizer
{
    NSLog(@"Mouvement ok");
    CGPoint translation = [recognizer translationInView:self];
    recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x, 
                                         recognizer.view.center.y + translation.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:self];


    if(recognizer.state == UIGestureRecognizerStateEnded)
    {
        NSLog(@"voila c'est fait");
        [[classementBoutons objectAtIndex:2]setFrame:CGRectMake(50, 50, 100, 100)];

    }
}

我不知道为什么插入到 Mutable 数组中的对象被取出后无法识别？

感谢您的回复。

胜利者
