Ios 带有长按手势的弹出式菜单

我对ios和核心动画都是新手，所以我正在做一些测试来适应它。 我有一个菜单，我正试图通过做一个长按手势来创建。我希望按钮通过向上设置动画，然后向下设置动画，然后消失。我让出现的部分工作，但我不知道如何使它消失。它也不允许我在UIgestureRecognitzerStateEnded语句中设置imageView的动画。基本上，我有两个问题：

释放长按时，如何设置按钮向下移动的动画

我怎么能只做其中一个按钮，而不是每次长按时都出现

这是我的.m.里的东西

-(void)onPress:(UILongPressGestureRecognizer*)longpress{

CGPoint touchCenter = [longpress locationInView:self.view];

UIImage *plus = [UIImage imageNamed:@"plus"];
imageView = [[UIImageView alloc]initWithImage:plus];

CGRect imageViewFrame = CGRectMake(0, 0, 35, 35);
imageViewFrame.origin = CGPointMake(touchCenter.x - imageViewFrame.size.width / 2.0f, touchCenter.y - imageViewFrame.size.height / 2.0f);
imageView.frame = imageViewFrame;

if (longpress.state == UIGestureRecognizerStateBegan) {
    [self.view addSubview:imageView];

    [UIView animateWithDuration:0.6 animations:^{
        CGAffineTransform moveTrans = CGAffineTransformMakeTranslation(0, -40);
        imageView.transform = moveTrans;
    }];
    NSLog(@"Long press");
    return;
}else{


if (longpress.state == UIGestureRecognizerStateEnded || longpress.state == UIGestureRecognizerStateCancelled || longpress.state == UIGestureRecognizerStateFailed) {

    [UIView animateWithDuration:0.6 animations:^{
        CGAffineTransform moveTrans = CGAffineTransformMakeTranslation(0, 40);
        imageView.transform = moveTrans;
        NSLog(@"long press done");
    }];

}


}

}

还有我的

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@interface ViewController : UIViewController<UIGestureRecognizerDelegate>
{
    UIImageView *imageView;
    CAShapeLayer *layer;

}
@property(nonatomic) float angle;
@property(nonatomic, strong) UIImageView *imageView;
@property (nonatomic, strong) UIImage *image;
@end

#导入
#进口
@界面ViewController:UIViewController
{
UIImageView*图像视图；
CAShapeLayer*层；
}
@性质（非原子）浮动角；
@属性（非原子，强）UIImageView*imageView；
@属性（非原子，强）UIImage*image；
@结束

我现在知道你想做什么了。但是我修改了你的一些代码：

@interface ViewController ()
@property (strong, nonatomic) UIView *moveView;
@end

- (void)viewDidLoad
{
    [super viewDidLoad];
    UILongPressGestureRecognizer *recoginzer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(onPress:)];
    [self.view addGestureRecognizer:recoginzer];
}

- (void)onPress:(UILongPressGestureRecognizer*)longpress {
    CGPoint location = [longpress locationInView:self.view];
    if (longpress.state == UIGestureRecognizerStateBegan) {
        if (!self.moveView) {
            self.moveView = [[UIView alloc] initWithFrame:CGRectMake(location.x, location.y, 100, 100)];
            self.moveView.backgroundColor = [UIColor redColor];
            [self.view addSubview:self.moveView];
        } else {
            self.moveView.frame = CGRectMake(location.x, location.y, 100, 100);
        }
        [UIView animateWithDuration:0.6 animations:^{
            CGAffineTransform moveTrans = CGAffineTransformMakeTranslation(0, -40);
            self.moveView.transform = moveTrans;
        }];
        NSLog(@"Long press");
    } else if (longpress.state == UIGestureRecognizerStateEnded || longpress.state == UIGestureRecognizerStateCancelled || longpress.state == UIGestureRecognizerStateFailed) {
            [UIView animateWithDuration:0.6 animations:^{
                CGAffineTransform moveTrans = CGAffineTransformMakeTranslation(0, 40);
                self.moveView.transform = moveTrans;
                NSLog(@"long press done");
            }];
    }
}

如果您需要更多帮助，请告诉我。

这就是我要寻找的行为，但我如何将其应用于uibutton而不是uiview？@StevenP。只需将按钮添加到该视图中。
