如何在视图控制器周围移动多个 UIImage 视图？

我已经设法使用了这段代码；

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    printf("touch began --------- |n");


}


-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    printf("touch moved --------- |n");


    UITouch *myTouch = [touches anyObject];
    startPoint = [myTouch locationInView:self.view];



    ball.center = CGPointMake(startPoint.x, startPoint.y);

    }


-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    printf("touch end --------- |n");

    }

上面的代码使我可以通过触摸移动一个 UIImage 视图，但是，我希望能够移动 100 个左右。当前，此代码还可以在您在屏幕区域周围移动手指时，图像会跳到您的手指。

这是最好的方法吗？还是平移手势更好？

请帮我完成，以便我可以通过触摸在我的视图控制器周围移动多个图像，如果您使用上面的代码，请阻止图像跳跃！

请帮忙！

.H 文件用于回答推荐；

@interface CMViewController : UIViewController {
    CGPoint startPoint;


}


@property CGPoint startPoint;

@property (strong, nonatomic) IBOutlet UIImageView *smyImageView;
@property (strong, nonatomic) IBOutlet UIImageView *smyImageView1;





@end

谢谢

您可以在下面使用。我将它用于在屏幕上移动的多个图像。它对我有用。

UIPanGestureRecognizer *span=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(onsPan:)];

 [smyImageView addGestureRecognizer:span];

   UIPanGestureRecognizer *span1=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(onsPan1:)];

   [smyImageView1 addGestureRecognizer:span1];

移动（平移）：

- (void)onsPan:(UIPanGestureRecognizer *)recognizer {

   CGPoint translation = [recognizer translationInView:self.view];
    recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x,
                                         recognizer.view.center.y + translation.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];

}

- (void)onsPan1:(UIPanGestureRecognizer *)recognizer {

    CGPoint translation = [recognizer translationInView:self.view];
    recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x,
                                         recognizer.view.center.y + translation.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];

}
