ThomasM,
We had similar ideas about encapsulating behavior inside a custom view (say, a slider with companion labels for min/max/current values, with value-changed events also handled by the control internally).
In our current best-practice, we would design the ShareView in Interface Builder (ShareView.xib
), as described by Eimantas in his answer. We then embed the ShareView to the view hierarchy in MainViewController.xib
.
I wrote up how we embed custom-view Nibs inside other Nibs in our iOS developer blog. The crux is overriding -awakeAfterUsingCoder:
in your custom view, replacing the object loaded from MainViewController.xib with the one loaded from the “embedded” Nib (ShareView.xib).
Something along these lines:
// ShareView.m
- (id) awakeAfterUsingCoder:(NSCoder*)aDecoder {
BOOL theThingThatGotLoadedWasJustAPlaceholder = ([[self subviews] count] == 0);
if (theThingThatGotLoadedWasJustAPlaceholder) {
// load the embedded view from its Nib
ShareView* theRealThing = [[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([ShareView class]) owner:nil options:nil] objectAtIndex:0];
// pass properties through
theRealThing.frame = self.frame;
theRealThing.autoresizingMask = self.autoresizingMask;
[self release];
self = [theRealThing retain];
}
return self;
}
