IntelliSense-style completion-without-TAB in Xcode

开发者_如何学CIn Xcode, to complete a suggestion you need to press the TAB key. In Visual Studio, you can just type some punctuation and it will finish the suggestion.

e.g. in VS, typing f.m(); could expand to foo.method();, whereas in Xcode you'd have to type fTAB.mTAB();.

Is there any way to emulate VS's behaviour in Xcode?
