像Twitter那样。Tab Bar下面有三个View。Tab Bar右上角有按钮，点击会打开一个新建Tweets的Modal View。我想设定那个Modal View的delegate。但是我发现没有地方prepare segue - V2EX

我想从Modal View那里获取“回调”信息，搜了一下说应该在prepareForSegue的时候设置它的delegate。
我在Tab Bar包含的那三个View的prepareForSegue里都打了log，但是弹出Modal View的时候都没显示。
好像在那三个View里设置prepareForSegue没用。
右上角那个按钮应该是Tab Bar的。但是Tab Bar本身又没有一个Controller。
请问我应该在哪里设置prepareForSegue？

谢谢。
