ios - 如何将 UILabel 重新定位在与另一个 UILabel 完全相同的位置

Question

我正在尝试将 UILabel 重新定位在另一个 UILabel 上(相同位置)。它没有将自己精确定位在目标 UILabel 上。

见下面的代码

let element1yPosition = element1.frame.origin.y. // Element 1 y Position

let element2yPosition = element2.frame.origin.y. // Element 2 y Position

UIView.animate(withDuration: 1.0, animations: {

    element1.frame.origin.y = element2yPosition     // Repositioning stage. 
                                                   //Fails because Element 1 doesn't re-position itself in the exact same position as Element 2 as required.

})

你能试试吗

UIView.animate(withDuration: 1.0, animations: {

   element1.frame = element2.frame 

})
