How to navigate to another viewcontroller with PUSH style from UITabBarController page - ios

Question

First of all, I'm a beginner. forgive me for this stupid question.
I make two child pages usingUITabBarController, the first page including aUIButton, and alsl I make a another page (DetailPage). I connectted the button andDetailPage with segue. but the style of segue cannot be setted to push.(this will trigger a error , push style only used forUINavigatorController).
So, when I click the button , how to navigate to DetailPage with PUSH style?
I try a new method, UsingUINavigatorController to manage first page and DetailPage, and then make thisUINavigatorController embed intoUITabItem. when I finish this, I can navigate to DetailPage with push style. But another question occured, when navigating DetailPage , the TabBar is always stay the bottom of page. I wanna allUITabBarController will be pushed to left side.
The effect what I want like this picture:
How can I optimize my code?

Answer 1

Implement delegate(UITabBarControllerDelegate) method like this :
- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {
NSArray *tabViewControllers = tabBarController.viewControllers;
UIView * fromView = tabBarController.selectedViewController.view;
UIView * toView = viewController.view;
if (fromView == toView)
return false;
NSUInteger fromIndex = [tabViewControllers indexOfObject:tabBarController.selectedViewController];
NSUInteger toIndex = [tabViewControllers indexOfObject:viewController];
[UIView transitionFromView:fromView
toView:toView
duration:0.3
options: toIndex > fromIndex ? UIViewAnimationOptionTransitionFlipFromLeft : UIViewAnimationOptionTransitionFlipFromRight
completion:^(BOOL finished) {
if (finished) {
tabBarController.selectedIndex = toIndex;
}
}];
return true;
}
This is for flip animationJust change animation
For Push :
CATransition* transition = [CATransition animation];
[transition setDuration:0.3];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[transition setFillMode:kCAFillModeBoth];
[transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[view.layer addAnimation:transition forKey:kCATransition];
For Pop :
CATransition* transition = [CATransition animation];
[transition setDuration:0.3];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[transition setFillMode:kCAFillModeBoth];
[transition setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[view.layer addAnimation:transition forKey:kCATransition];
Now Its up to you, best of luck....
