Auto completion in xcode

In XCode 3.2.2 completion works whenever it chooses to.

One time it will, one time it won't. Is there some flag or add-on to increase the auto-completion success rate ???

Is there maybe a better code editor that can link to xcode in a good manner which has better coding capabilities then XCode 开发者_运维知识库?

Thanks

I don't know. Maybe it depends on the way you code but it works for me most of the time. There is some case that it will not work, for example, too much complicated like [[self.a doB] doC];

Can you post me some code that it doesn't work for you?
