ios - 删除UIView动画加速

Question

如何删除UIView Animations的加速和减速动画？

如果您不明白我的意思，则动画启动时会加速，然后结束时会减速。我希望动画速度恒定。
这是我的代码的示例(我必须使用旧的动画方式)。

-(void)animate:(NSString*)animationID finished:(BOOL)finished context:(void*)context {         
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationDidStopSelector:@selector(animateStop:finished:context:)];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDuration:3];
    Motion.center = (*PathPoints)[Location];
    [UIView commitAnimations];        
}

[UIView setAnimationCurve: UIViewAnimationCurveLinear];
