Loading a window from nib

Question

Hi,
let me try to explain what i want. I have an empty nib file and i've added a panel to it that is used as a sheet. Now normally what i wold do with multiple windows is as follows:
a) user performs some action to activate the new window
b) the window is instantiated and shown until the user closes it
c) some action is performed and the window is destroyed
How could i do that in cocoa? I don't need any explanation on how to use sheets, all i need is pointers on how to instantiate a panel from the nib and then release it. I'm currently using nsbundle's loadNibNamed, but this instantiates the panel immediately. Is there any way to instantiate it manually and destroy it when not needed any longer? Ideal solution would be a if the window was read from the nib every time instead of loading the nib to memory.

Hi,
this is why Cocoa/Objective-C code tends to get less spaghetti. Try to follow a strict MVC design paradigm and you will be happy whenever you need to adjust the code. More code often is a good thing, especially if you need flexibility.
Delegates and owners (as it is the case of a NIB) are powerful solutions to write real OO code. Only the window controller of this window is responsible for how it should behave etc.
Of course you can have multiple windows in a single NIB and connect them via IBOutlets to one class. So you could control the window from one controller - especially if it is more a panel like window, that rarely pops open.
