Hi just stated to use the ComponentKit library given from facebook
and i have been going through all their documentation but i could not find how to use their CKComponentController class.
Like how to push a view controller and about the navigation of various view controllers.
if any of you are aware of how to use the CKComponentController please let me know
i'm a bit stuck due to less documentation
Thank You. Imran.
Our usual approach is to pass an object with a weak reference to the navigation controller as the "context" object that is passed to the top-level component.
Be sure it's a weak reference or you'll end up with a retain cycle!
As for accessing it in the component controller, expose the context object as a property on your component and then read that property off of self.component.
I worked this out, but it's definitely NOT immediately obvious. I had to dig through the source code. StoryViewController extends UIViewController.
@interface StoryViewController () <
CKComponentProvider,
CKComponentHostingViewDelegate
>
@end
@implementation StoryViewController {
CKComponentDataSource *_componentDataSource;
CKComponentFlexibleSizeRangeProvider *_sizeRangeProvider;
}
- (void)viewDidLoad {
_sizeRangeProvider = [CKComponentFlexibleSizeRangeProvider providerWithFlexibility:CKComponentSizeRangeFlexibleHeight];
CKComponentHostingView *hostingView = [[CKComponentHostingView alloc] initWithComponentProvider:[self class]
sizeRangeProvider:_sizeRangeProvider
context:nil];
hostingView.delegate = self;
hostingView.model = self.story;
CGSize size = [hostingView sizeThatFits:CGSizeMake(self.view.frame.size.width, FLT_MAX)];
hostingView.frame = CGRectMake(0, 0, size.width, size.height);
[self.view addSubview:hostingView];
}
#pragma mark - CKComponentProvider
+ (CKComponent *)componentForModel:(id<NSObject>)story context:(id<NSObject>)context {
return [StoryComponent newWithStory:story context:nil];
}
#pragma mark - CKComponentHostingViewDelegate <NSObject>
- (void)componentHostingViewDidInvalidateSize:(CKComponentHostingView *)hostingView {
NSLog(@"componentHostingViewDidInvalidateSize");
}
@end
