ios - navigationItem.titleView 在更新时闪烁 [英] ios - navigationItem.titleView blinks when updated

问题描述

我有一个 UIView，持有一个 UIButton，设置为我的 navigationItem.titleView.当我更新此按钮的文本时，它会短暂闪烁(随着新文本消失并重新出现.)

I have a UIView, holding a UIButton, set as my navigationItem.titleView. When I update the text for this button, it briefly blinks (disappearing and reappearing with the new text.)

有没有办法让它在更改时保持可见?那么，如果我更改 2015-2016，它看起来好像只有最后一位数字更新为 6?

Is there anyway to keep it visible when it's changed? So, if I change 2015-2016 it appears as if only the last digit is updated to 6?

谢谢

推荐答案

我解决了我的问题.与 navigationBar 的 titleView 中的任何内容相比，这与 UIButton 的关系更大.

I solved my problem. This has more to do with UIButton than anything in the navigationBar's titleView.

如果一个 UIButton 被设置为 [yourButton buttonWithType:UIButtonTypeCustom]，那么当它被更新为 [yourButton setTitle:@" 时它不会闪烁title" forState:UIControlStateNormal];

If a UIButton is set as [yourButton buttonWithType:UIButtonTypeCustom], then it will not blink when it has been updated with [yourButton setTitle:@"title" forState:UIControlStateNormal];
