iOS仿微信摇一摇动画效果加震动音效实例

方法二. 在摇一摇开始和结束里添加摇动动画效果及菊花效果

/**
 * 摇动开始
 */
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {

  NSLog(@"开始摇了");

  // 菊花显示并开始转动
  self.aiLoad.hidden = NO;
  [self.aiLoad startAnimating];

  AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

  CGFloat offset = self.bgImgView.height * 0.5;
  CGFloat duration = 0.4;
  [UIView animateWithDuration:duration animations:^{
    self.imgUp.y -= offset;
    self.imgDown.y += offset;
  }];
}

/**
 * 摇动结束
 */
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {

  NSLog(@"摇动结束");

  // 不是摇一摇事件则返回
  if (motion != UIEventSubtypeMotionShake) return;

  // 1.添加摇动动画
  CGFloat offset = self.bgImgView.height * 0.5;
  CGFloat duration = 0.4;
  [UIView animateWithDuration:duration animations:^{
    self.imgUp.y += offset;
    self.imgDown.y -= offset;
  }];

  // 菊花暂停转动并隐藏
  [self.aiLoad stopAnimating];
  self.aiLoad.hidden = YES;
}
