Mac Forum / Programming / Mac Programming / August 2005How to properly merge files
I am finding it difficult to design-as-I-go, by which I mean, make up the design as I go along instead of laying everything out in crystaline perfection before I get started. For example, in IB, I create a class and its various outlets and actions. I save the files. I go to Xcode and implement some of the class, adding member variables and function bodies. Then I decide I need a new outlet, say a new textfield. I got back to IB and add the textfield to the class. I save the files again. This time it asks if I want to merge them. I say yes. At this point, everything goes screwy. No matter what merge options I choose (left, right, both, etc.), the merged file is always an overwrite of the IB class, wiping out any code I wrote in Xcode? It is fairly unacceptable to believe that I have to have my interface perfectly designed from step one and that I cannot modify it during the development of a project because that will wipe out the existing code. This can't be how Apple expects people to write large programs? Besides, merge is there, waiting to be used, it just doesn't seem to merge anything. Am I missing something obvious? This is frustrating, but I'm sure I'm just doing it wrong. Thanks. ________________________________________________________________________ Keith Wiley kwiley@cs.unm.edu http://www.unm.edu/~keithw "Yet mark his perfect self-contentment, and hence learn his lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy." -- Edwin A.

I don't know what's going wrong in your case, but I've never had a reason to try it, and I don't get my interfaces perfect from day one either.

Sounds a lot easier. I'll try it. Thanks. ________________________________________________________________________ Keith Wiley kwiley@cs.unm.edu http://www.unm.edu/~keithw "Yet mark his perfect self-contentment, and hence learn his lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy." -- Edwin A.

Everyone who has tried has been bitten by it (at least I have...) It is the world's most confusing software. Apart from dragging, you can also double-click your instance in IB to switch to the classes pane and then choose 'Read Myheader.h' from the Classes menu. I don't know why _only that_ menu item has no shortcut assigned. Worst decission ever! patrick > Apart from dragging, you can also double-click your instance in IB to > switch to the classes pane and then choose 'Read Myheader.h' from the > Classes menu.

I personally feel that "drag the file to the nib window" is a pretty good shortcut for that particular command. > > Apart from dragging, you can also double-click your instance in IB to > > switch to the classes pane and then choose 'Read Myheader.h' from the [quoted text clipped - 3 lines] > I personally feel that "drag the file to the nib window" is a pretty good > shortcut for that particular command. Yes, but somehow I always have my desktop clutterred with Xcode and IB windows, so I have to 'dig' through the rubble to locate my header (or implementation) file. A shortcut to re-import a class interface (or possibly _all_) would be welcome. I also would like the proper selection meta-keys in the instances pane, but that didn't make it into 10.4 either. patrick >> > Apart from dragging, you can also double-click your instance in IB to >> > switch to the classes pane and then choose 'Read Myheader.h' from the [quoted text clipped - 10 lines] > meta-keys in the instances pane, but that didn't make it into 10.4 > either. You can also just drag the file directly from the Xcode project window, or by using the proxy icon in the title bar of the file's window, which is what I always do. No need to go hunting for it in the Finder. Presumably if you've just made a change, you have the header open in an editor, so you can easily get to its proxy icon. Thanks again for all the good ideas on this topic...and others I have inquired about. ________________________________________________________________________ Keith Wiley kwiley@cs.unm.edu http://www.unm.edu/~keithw "Yet mark his perfect self-contentment, and hence learn his lesson, that to be self-contented is to be vile and ignorant, and that to aspire is better than to be blindly and impotently happy." -- Edwin A.
