masonry使用UIView动画需要注意什么

        [self.view addSubview:self.animateView];
        [self.animateView mas_makeConstraints:^(MASConstraintMaker *make) {
            
            make.left.right.equalTo(self.view).offset(0);
            make.height.mas_equalTo(200);
            make.bottom.equalTo(self.view).offset(200);
        }];
        //强制绘制
        [self.animateView.superview layoutIfNeeded];
        
        [UIView animateWithDuration:0.3 animations:^{
            
            [self.animateView mas_updateConstraints:^(MASConstraintMaker *make) {
                
                make.bottom.equalTo(self.view).offset(0);
            }];
            //强制绘制
            [self.animateView.superview layoutIfNeeded];
        }];
