Since UIButtoninherits from UIView, you can just set the hiddenproperty on the button (via UIButton doc)
由于UIButton继承自UIView，您只需hidden在按钮上设置属性（通过UIButton doc）
button.hidden = YES;

Consider enabling or disabling the buttons instead. You get the same end result, but it's a little bit more consistent since things aren't appearing and dissapearing out of nowhere.
考虑启用或禁用按钮。您会得到相同的最终结果，但它更加一致，因为事物不会凭空出现和消失。

Instead of visible, the property you are looking for is hidden.
您要查找的属性不是可见的，而是隐藏的。
saveButton.hidden = YES;
That should do the trick.
这应该够了吧。

Simply Add IBoutlet property in .h file. like
只需在 .h 文件中添加 IBoutlet 属性。喜欢
@property (strong, nonatomic) IBOutlet UIButton *resendOtpButtom;
then add
然后加
_resendOtpButtom.hidden = YES; in .m file.
