how to activate intellisense in xCode?

[jjan014]

In visual studio,there's intellisense.So I could see the member methods and member variables of an object easily.
I tried it in xCode,but nothing appears.If I type "variable->",a context box should appear and its member variables and member method should appear.How can I achieve it?In Visual studio pressing "shift+Ctrl+space" let's intllisense activated.In xCode,what should I press to activate intellisense for an object?

You can press Escape each time you want to have the full list of autocompletions, OR install this plugin which saved me hours of typing, forcing XCode to always show the autocompletion list
