当尝试使用自动版式制作动画时，您应该不直接更改视图的帧。

When trying to animate with Auto Layout, you should not change view's frames directly. Instead, you should animate changes in constraints.

要从故事板访问约束，您可以简单地为他们创建IBOutlets 。

[containerView layoutIfNeeded]; // complete pending layout operations (optional)
[UIView animateWithDuration:1.0 animations:^{

    // Update constraints
    self.viewConstraint1.constant = NEW_VALUE;
    self.viewConstraint2.constant = NEW_VALUE;

    // Animate the changes
    [containerView layoutIfNeeded]; 
}];

注意，你通常想要调用layoutIfNeeded在超级视图

我建议您阅读Apple的官方指南。
