iPhone模式视图动画帮助 [英] iPhone Modal View Animation Help

问题描述

我没有做过太多的动画，我需要一些帮助与此有关。我有一个 tabBarController 作为我的根控制器，而我希望有另一个 tabBarController ，我希望把它作为一个模态视图控制器，我有动画的一个问题。

I have not done much animation, and I need some help with this. I have a tabBarController as my root controller, and I want to have another tabBarController, and I want to bring it up as a Modal View Controller, and I have a problem with the animation.

目前有四种动画为 modalViewControllers ，即

typedef enum {
UIModalTransitionStyleCoverVertical = 0,
UIModalTransitionStyleFlipHorizontal,
UIModalTransitionStyleCrossDissolve,
UIModalTransitionStylePartialCurl,
} UIModalTransitionStyle;

我想要一个不同的动画 - 从左侧向右滑动。 - 我该怎么做动画

任何帮助？

我的想法推到tabBarController导航堆栈很烂！苹果公司的这一做法评论：

My idea to push a tabBarController onto the navigation stack sucks! Apple's comment on this approach:

您永远不希望一个标签栏控制器推到导航控制器的导航堆栈。这样将创建一个不寻常的情况，即在
  标签栏只会出现，而特定视图控制器是在导航堆栈的顶部。标签栏被设计成永久的，所以这种方法的瞬态会引起混乱给用户。

You never want to push a tab bar controller onto the navigation stack of a navigation controller. Doing so creates an unusual situation whereby the tab bar appears only while a specific view controller is at the top of the navigation stack. Tab bars are designed to be persistent, and so this transient approach can be confusing to users.

我的想法。有人帮我动画模式视图控制器。

I am out of ideas. Someone help me with the animation for modal view controllers.

推荐答案

您可以手动编写动画code。下面是一些常见步骤：

You could write the animation code manually. Here are the general steps:

• 创建的UIViewController 的一个子类（主要是废的控制器来容纳你的的UITabBarController ） - 我通常称之为 ShellViewController 。


• 在 ShellViewController 的的init 办法（你会用哪一个），设置它的架屏幕之外的权利，例如： [self.view SETFRAME：CGRectMake（320，0，320，480）;


• 创建在 ShellViewController 的两种方法
  
  
  
  • - （无效）presentSelf
  
  
  • - （无效）dismissSelf
  
  
  • Create a subclass of UIViewController (essentially a dud controller to house your UITabBarController) - I usually call this ShellViewController.
  • In the ShellViewController's init method (whichever one you would use), set its frame outside of the screen to the right, e.g. [self.view setFrame:CGRectMake(320, 0, 320, 480)];
  • Create two methods within ShellViewController
    • - (void)presentSelf
    • - (void)dismissSelf

    下面是code的动画式（例如 - （无效）presentSelf 法）：

    Here is the code for animating-in (e.g. the - (void)presentSelf method):

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.15]; //the double represents seconds
    [UIView setAnimationDelegate:self];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
    [[self view] setFrame:CGRectMake(0, 0, 320, 480)];
    [UIView commitAnimations];
    

    下面是动画时的code（例如 - （无效）dismissSelf 法）：

    Here is the code for animating-out (e.g. the - (void)dismissSelf method):

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.15];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
    [[self view] setFrame:CGRectMake(320, 0, 320, 480)];
    [UIView commitAnimations];
    

    请记住，这些动画的方法做的只有的是：动画。他们不与当前视图也不与 ShellViewController 的看法/这是在被动画子视图/禁用进行互动。你需要动画过程中手动禁用用户交互，然后恢复其动画完成后。有执行时动画完成了一个选择器的的UIView 方法：

    Keep in mind that these animation methods do only that: animate. They don't disable interaction with the current view nor with the ShellViewController's view/subviews which are being animated in/out. You'll need to manually disable user interaction during animation and then reinstate it after the animation is finished. There is a UIView method that performs a selector when animation is finished:

    [UIView setAnimationDidStopSelector:@selector(enableUserInteraction)];
    

    您可以把后，这一权利[UIView的setAnimationDelegate：个体经营] 中的每个动画块以上。当然，你需要写在 enableUserInteraction 方法自己...和 disableUserInteraction 对于这个问题的方法。

    You can put this right after the [UIView setAnimationDelegate:self] in each animation block above. Of course, you would need to write the enableUserInteraction method yourself... and disableUserInteraction method for that matter.

    这是一件麻烦事走这条路线，但它的作品。一旦你的 ShellViewController 写上去，它使一个很好的可重用的代码片段。

    It is a hassle to go this route, but it works. Once you get the ShellViewController written up, it makes for a nice reusable snippet.
