使用了Autolaout的檢視的動畫

方法一：簡單的說就是先找到想要變化的NSLayoutConstraint

然後改變constant值

    NSLayoutConstraint * _bottomCelectVLocRight;
        _bottomCelectVLocRight.constant = 0;

        [UIView animateWithDuration:.5 animations:^{
            
            [self.view layoutIfNeeded];
            
        }];

        [UIView animateWithDuration:.5 animations:^{         
           _bottomCoolectView.translatesAutoresizingMaskIntoConstraints = YES;
            _bottomCoolectView.frame = CGRectMake(CGRectGetMinX(_bottomCoolectView.frame)-bottomCoolectViewWidth, CGRectGetMinY(_bottomCoolectView.frame), CGRectGetWidth(_bottomCoolectView.frame), CGRectGetHeight(_bottomCoolectView.frame));
                        
        }];
