问题
I have added some items, such as the pictured "round rect button" in Interface Builder to my .xib file, but I am not able to remove them.
If I just click on the 'x', it disappears, but it's not removed from the interface. How do I actually delete it?
回答1:
Highlight the items as shown below and hit the delete key
If you can't see the menu it can be expanded by clicking the arrow in this image
