iPhone 向左推视图控制器 [英] iPhone Pushing View Controller in a left direction

问题描述

我有一个应用程序，它有一个中心视图，它的每一侧都有两个视图.我想要两个导航栏按钮，分别是向左和向右，将新的导航控制器从左侧或右侧推送到视图上.

I have an app that has a centre view with two views off to each side of it. I want to have two navigation bar buttons, left and right which push a new navigation controller onto the view from the left or the right.

当您使用 NavigationController 的 pushviewController: 方法通过推送新视图来更改视图时，视图似乎从右侧滑入.我如何将其更改为从左侧滑入?

When you change views by pushing a new view using the pushviewController: method of NavigationController, the view appears to slide in from the right. how do i change this to slide in from the left?

推荐答案

我不使用导航控制器，而是移动视图.

Instead of using a navigation controller, I would just move the view.

CGRect inFrame = [currentView frame];
CGRect outFrame = firstFrame;
outFrame.origin.x -= inFrame.size.width;

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];

[newView setFrame:inFrame];
currentView setFrame:outFrame];

[UIView commitAnimations];
