Is there an easy way for Xcode to let me know which methods of a protocol are required?

Question

My experience is in Java development with Eclipse, where if I add a protocol in a header file there is a shortcut to add the required methods of that protocol in the implementation file. Does Xcode have a similar shortcut?

For example: In my .h, I define a class to conform to the UIPickerViewDelegate and UIPickerViewDataSource protocols.

@interface Something : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource> {

}

These protocols have required methods that I need to implement, and I am always checking the documentation to see which ones. Is there some method for Xcode to insert stubs for these required methods in the implementation file?

Answer 1

So you're asking if, when you type an @protocol command in an ObjC header file, can Xcode automatically put the @synthesize in the .m file?

No. You have to do it manually. There is no built-in way to do this, although someone may have written a script to do that.

Answer 2

I wondered the same thing and I found this neat trick:

I've been finding it very useful. Basically you rightclick the protocol name, and choose "Jump to definition" - it takes you to the relevant header file, from whence you can just copy and paste the relevant declarations. Still a little manual but far less so.
