addSubview动画 [英] addSubview animation

问题描述

我主要的UIView，我显示不同的数据。然后，我把一个按钮，它显示子视图是这样的：

I have main UIView where I display different data. Then I put a button, which displays subview like this:

- (IBAction) buttonClicked:(id)sender
{
    UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(25,25,50,20)];
    UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(25,25,50,25)];
    newLabel.text = @"some text";
    [newView addSubview:newLabel];

    [self.view addSubview:newView];
    [newLabel release];
    [newView release];
}

NewView的出现很好，但它并没有动画本身的任何方式，它只是会立即出现。如何添加动画的某种NewView的时候会出现？如缩放或向下滑动或者类似的东西。有一些简单的code？

newView appears fine, but it doesn't animate itself any way, it just appears immediately. How can I add some kind of animation when newView appears? Like zoom or slide down or something like that. Is there some simple code?

推荐答案

您可以使用UIView的动画：

Hi You could use the UIView Animations:

[newView setFrame:CGRectMake( 0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen!
[UIView beginAnimations:@"animateTableView" context:nil];
[UIView setAnimationDuration:0.4];
[newView setFrame:CGRectMake( 0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen!
[UIView commitAnimations];

该SDK现在这个数字为你和动画视图以你给它的位置。
这适用于UIViews的大多数属性：α，规模，范围，框架等

The SDK will now figure this out for you and animate the view to the positions you gave it. This works for most properties of UIViews: alpha, scale, bounds, frames, etc.

有也建立动画翻页和卷曲：

There are also build in animations as flip and curl:

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
                           forView:newView
                            cache:YES];

[self.navigationController.view addSubview:settingsView.view];
[UIView commitAnimations];

希望这有助于出来让你开始：）

Hope this helps out getting you started:)
