如何在摇动后调用谷歌页面

Question

我试着在摇晃iPhone后调用谷歌页面。我试过这样：

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if(event.type == UIEventSubtypeMotionShake)
    {
        [self shakemethod];
        [self open];
      
    }
}
-(void)shakemethod
{
CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"position"];
        [shake setDuration:1.1];
        [shake setRepeatCount:2];
        [shake setAutoreverses:YES];
        [shake setFromValue:[NSValue valueWithCGPoint:
                             CGPointMake(lockImage.center.x - 15,lockImage.center.y)]];
        [shake setToValue:[NSValue valueWithCGPoint:
                           CGPointMake(lockImage.center.x + 15, lockImage.center.y)]];
        [lockImage.layer addAnimation:shake forKey:@"position"];
}
-(void)open
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://google.co.in"]];
}

两种方法工作，但当我摇动iPhone时，摇动的图像没有显示，但谷歌页面打开。我需要在摇手机时先摇一摇图片，摇完后打开谷歌页面。

将delgate自身设置为抖动动画，然后在动画结束时，delgate调用打开方法

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if(event.type == UIEventSubtypeMotionShake)
    {
        [self shakemethod];
    }
}
-(void)shakemethod
{
CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"position"];
        [shake setDuration:1.1];
        [shake setRepeatCount:2];
        [shake setAutoreverses:YES];
       //set animation delgate to self
        [shake setDelegate:self];
        [shake setFromValue:[NSValue valueWithCGPoint:
                             CGPointMake(lockImage.center.x - 15,lockImage.center.y)]];
        [shake setToValue:[NSValue valueWithCGPoint:
                           CGPointMake(lockImage.center.x + 15, lockImage.center.y)]];
        [lockImage.layer addAnimation:shake forKey:@"position"];
}
   //when animation will finish call the open method
    -(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag
    {
            [self open];
    }
    -(void)open
    {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://google.co.in"]];
    }

希望这是你想要的。
