    CGFloat newWidth = self.hoverBtn.bounds.size.width;
    CGFloat newHeight = self.hoverBtn.bounds.size.height;
    
    newX = (newX < [UIScreen mainScreen].bounds.size.width / 2.0 ? 10 : [UIScreen mainScreen].bounds.size.width - newWidth - 10);
    
    [UIView animateWithDuration:0.2 animations:^{
        
        hoverBtn.frame = CGRectMake(newX, newY, newWidth, newHeight);
    } completion:^(BOOL finished) {
        //hoverBtnCenter:记录按钮原始位置的中心点
        hoverBtnCenter = self.hoverBtn.center;
    }];
