问题描述

I'm using storyboard to create my new iPad project. I want use the custom modal segue to have better transitions between views. My question is how do I use the custom modal and is there any tutorials out there that show using custom modal segues?

推荐答案

此自定义序列弹回导航堆栈的根.如果您想返回一级，请使用普通弹出窗口而不是popToViewController".我就是喜欢这个方法的名字.

This custom seque pops back to the root of a navigation stack. Use a normal pop instead of "popToViewController" if you want to go back one level. I just love the name of this method.

标题:

#import <UIKit/UIKit.h>

@interface FlipTopPopToRoot : UIStoryboardSegue

@end

实现:

#import "FlipTopPopToRoot.h"

@implementation FlipTopPopToRoot

- (void) perform {

UIViewController *src = (UIViewController *) self.sourceViewController;
[UIView transitionWithView:src.navigationController.view duration:0.5
                   options:UIViewAnimationOptionTransitionFlipFromTop
                animations:^{
                    [src.navigationController popToViewController:[src.navigationController.viewControllers objectAtIndex:0] animated:NO];;
                }
                completion:NULL];
}

@end
