問題描述

界面生成器添加了一個標籤欄按鈕,但未顯示 (Interface builder added one tab bar button, but not showing up)

I replaced one tab bar button in interface builder. It was "Recent" button, I changed it to "Contacts" button. Now the tab bar button not showing up, but I could click on that position, and action does work. The neighbor unchanged tab bars have no problem though.

I could not find any place to set the visibility of Tab Bar button. 

Thanks.

參考解法

方法 1:

When you change it to the Contacts button make sure you select the Contacts option from the drop down list of apple provide tab bar buttons ‑ if you type in "Contacts" as the title of a bar button that has been selected as recent ‑ this will cause problems and may be causing the problem you are experiencing.
