ios中的动画期间,imageview的手势不起作用

ios中的动画期间,imageview的手势不起作用,ios,objective-c,animation,uiviewanimation,Ios,Objective C,Animation,Uiviewanimation,我正在实现一个imageView的动画。在这个动画中,我的气球图像是从下到上的,如果用户要触摸气球,我想将其隐藏。但是我的手势在动画过程中不起作用。有人能帮我吗。提前谢谢 img=[[UIImageView alloc]init]; img.frame=CGRectMake(150, 450, 50,50); [self.view addSubview:img]; img.image=[UIImage imageNamed:@"ballon3.png"];

img=[[UIImageView alloc]init];
     img.frame=CGRectMake(150, 450, 50,50);
     [self.view addSubview:img];
     img.image=[UIImage imageNamed:@"ballon3.png"];
     img.userInteractionEnabled=YES;

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapFrom:)];
tapGestureRecognizer.numberOfTapsRequired=1;
tapGestureRecognizer.delegate=self;
[img addGestureRecognizer:tapGestureRecognizer];

 [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationRepeatCount:30];
    [UIView setAnimationDuration:10];
    [UIView setAnimationCurve:UIViewAnimationCurveLinear];

CGAffineTransform scaleTrans =
    CGAffineTransformMakeScale(2, 2);

CGAffineTransform rotateTrans =
CGAffineTransformMakeRotation(angle * M_PI / 180);
img.transform = CGAffineTransformConcat(scaleTrans, rotateTrans);

img.center = CGPointMake(30,320);
这是手势的方法。但此方法未调用

-(void)handleTapFrom:(UIGestureRecognizer *)sender
{
  img.hidden = yes;  
}

您需要为动画使用块,以便喜欢:(注意
UIViewAnimationOptionAllowUserInteraction
,这很重要)

我让你设置你想要的其他参数


如果需要在iOS 4.0之前工作,则需要在单独的线程中设置动画

尝试NSLOg,如果控件正在那里,它是否在动画之外工作?如果没有,试着检查一些事情:-你的img使用的是强指针吗?-viewcontroller是否实现UIGestureRecognitzerDelegate?
[UIView animateWithDuration:10 delay:0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
    // Your animation here
} completion:^(BOOL finished) {
    // Once completed do stuff here;
}];
