模拟 iOS7 控制器推送动画

Question

到目前为止，我一直在使用来自this answer 的代码来模拟推送视图。但是现在视图推送动画发生了变化。有没有人有代码来模拟新的动画？

Answer 1

我找到了一种模拟它的方法，它非常接近原版。

您必须添加 MTAnimation（这是指数级缓和所必需的）。该库需要QuartzCore，因此如果尚未添加，则必须将其添加到项目设置中“构建阶段”中的“链接库”中。

这里是代码：

推送控制器动画

// Get the views
UIView * fromView = sourceViewController.view;
UIView * toView = destinationViewController.view;
UIView *darkenView = [[UIView alloc] initWithFrame:fromView.frame];
[darkenView setBackgroundColor:[UIColor colorWithRed:255 green:255 blue:255 alpha:0]];
[fromView addSubview:darkenView];

// Get the size of the view area.
CGRect viewSize = fromView.frame;

// Add the new view to the old view.
[fromView.superview addSubview:toView];

// Position the new view outside of the screen
toView.frame = CGRectMake( viewSize.size.width , viewSize.origin.y, viewSize.size.width, viewSize.size.height);
[UIView mt_animateViews:[NSArray arrayWithObjects:fromView, toView, nil]
               duration:.55
         timingFunction:MTTimingFunctionEaseOutExpo
                options:UIViewAnimationOptionAllowAnimatedContent
             animations:
    ^{
        // Animate the replacing of the views 
        fromView.frame =CGRectMake( -(viewSize.size.width/3) , viewSize.origin.y, viewSize.size.width, viewSize.size.height);
        toView.frame =CGRectMake(0, viewSize.origin.y, viewSize.size.width, viewSize.size.height);
        [darkenView setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:.1]];
    }
                 completion:
    ^{
        // Remove the old view 
        [darkenView removeFromSuperview];
        [fromView removeFromSuperview];
    }];

弹出控制器动画（如返回按钮）

// Get the views.
UIView * fromView = sourceViewController.view;
UIView * toView = destinationViewController.view;

// Get the size of the view area.
CGRect viewSize = fromView.frame;

// Add the new view to the old view.
[fromView.superview insertSubview:toView belowSubview:fromView];

// Position the new view outside of the screen
toView.frame = CGRectMake( -(viewSize.size.width/3) , viewSize.origin.y, viewSize.size.width, viewSize.size.height);

UIView *darkenView = [[UIView alloc] initWithFrame:toView.frame];
[darkenView setBackgroundColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:.1]];
[toView addSubview:darkenView];

[UIView animateWithDuration:0.35 delay:0 options:UIViewAnimationOptionAllowAnimatedContent animations:
^{
         // Animate the replacing of the views 
         fromView.frame =CGRectMake(viewSize.size.width , viewSize.origin.y, viewSize.size.width, viewSize.size.height);
         toView.frame =CGRectMake(0, viewSize.origin.y, viewSize.size.width, viewSize.size.height);
         darkenView.frame = toView.frame;
         [darkenView setBackgroundColor:[UIColor colorWithRed:255 green:255 blue:255 alpha:0]];
}
                 completion:^(BOOL finished)
{
    if (finished)
    {
        // Remove the old view 
        [fromView removeFromSuperview];
        [darkenView removeFromSuperview];
    }
}];
