PresentViewController与自定义“scale-from-center”ModalTransitionStyle [英] PresentViewController with custom “scale-from-center” ModalTransitionStyle

问题描述

我想实现自定义视图呈现过渡样式。这是我的代码：

I'm trying to implement custom view presenting transition style. Here is my code:

[myViewController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentViewController:myViewController animated:YES completion:^(void){}];

我想在呈现视图时实现从中心缩放效果。我使用JQuery UI进行了所需效果的演示： http://jsfiddle.net/c7ztP/

I'd like to achieve "scale from center" effect while presenting views. I made a demo of desired effect with JQuery UI: http://jsfiddle.net/c7ztP/

有办法吗？

推荐答案

From the initiating view controller i would do this

// OriginalViewController.h
newViewcontroller.view.transform = CGAffineTransformScale（CGAffineTransformIdentity，0.0f，0.0f）;
[self presentViewController：newViewController animated：NO completion：nil];

// OriginalViewController.h newViewcontroller.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.0f, 0.0f); [self presentViewController:newViewController animated:NO completion:nil];

在接收视图控制器上我会这样做

And on the receiving view controller I would do this

-(void)viewDidLoad {
   [UIView animateWithDuration:0.3f animations:^{
    self.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.0f, 1,0f);
   }];
}

为了这个工作，你需要 QuartzCore。框架。也让它更甜，我会添加零alpha的全alpha的动画，因为它看起来更好。

For this to work you'll need QuartzCore.framework. Also to make it sweeter I would add zero alpha to full alpha animated as it looks better.
