I have a class design issue I was hoping someone could help me out with.
I'm currently developing an iOS app that relies heavily on a remote API for all
of its data. Most data is requested in viewDidLoad.
The availability and format of data can change, and in response to that I need
to implement three different designs depending on how much data I have access
to: the normal design, a data not found design and a partial data design. I'm
trying to declare as much as possible in xib files.
Right now I have one 'master' view controller, which when all things go
according to plan, presents a view for all of the data. In cases where the data
is not available, it instantiates an "inner view" controller and assigns its
view to self.view:
if ([analysis length] == 0) {
hasReview = NO;
UnreviewedSPP* unreviewedSPPView = [[UnreviewedSPP alloc] init];
unreviewedSPPView.ProductName = self.productName;
unreviewedSPPView.SdcId = self.sdcId;
unreviewedSPPView.Delegate = self;
NSArray* newViews = [[NSBundle mainBundle]
loadNibNamed:@"UnreviewedSPP" owner:unreviewedSPPView options:nil];
self.view = [newViews objectAtIndex:0];
return;
}
This works pretty well, except for that fact that I cannot seem to push any new
views onto the navigationController stack from the inner view (using a custom
button that can execute a block):
[priceButton handleControlEvent:UIControlEventTouchUpInside withBlock:^{
WebViewController* wv = [[[WebViewController alloc]
initWithNibName:@"WebViewController" bundle:nil] autorelease];
wv.url = offerURL;
[Delegate performSelector:@selector(pushViewControllerFromSubview:)
withObject:wv];
}];
I've tried using a delegate pattern as well as assigning the outer view
controller's navigationcontroller as a property to the inner view. Neither
works.
This whole thing feels rather hackish, and I'm sure there's something by design
in the framework that stops this. Any thoughts?
