xcode 指令后的缩进不起作用

Question

I've been using xcode for some months and this has never happened before, i'm not sure whether i pressed something i shouldn't have or meddled with the settings. Basically i write something like for(int i=1;i<=n;i++) and press enter, and the cursor is on the next line above the instruction, so there's no visual subordination of what I'm about to write next.

If i press the tab key before writing a new instruction below and then write for instance cout<<ni<<endl; , the moment I press ; , the entire thing is moved in the same column(if that makes sense) again. This doesn't happen with other instructions like while or if. Help?

Answer 1

Normally indentation occurs when you open a block , as in type { . If you're using a blockless if then the code editor has to figure out after the fact what you're doing.

Answer 2

I'm not able to reproduce your problem, but here are a few tips:

To format a selection in the editor

Main menu: Editor > Structure > Re-indent ( or ^I )

To remove the automatic formatting when pressing ;

User Preferences: Text Editing > Automatic indent for : Uncheck the “;” box
