ios - 关闭模态视图后删除模态模糊效果
<p><p>目前我正在使用 MapView 开发一个项目，当用户按下按钮时，它会呈现一个模态视图。</p>
<p>modalView 使用了 iOS 8 典型的 Blur 效果。</p>
<p>问题是，我可以呈现带有模糊效果的模型 View ，并且可以将其关闭，但我无法移除 map 的模糊效果。</p>
<p>当前代码:</p>
<p>ViewController.m</p>
<pre><code>- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *buttonTitle = ;
if() {
;
AlarmViewController *modal = ;
modal.transitioningDelegate = self;
modal.modalPresentationStyle = UIModalPresentationOverCurrentContext;
-(void)blurEffectMethod {
UIVisualEffect *blurEffect;
blurEffect = ;
UIVisualEffectView *visualEffectView;
if (_radiusSlider.hidden == NO) {
visualEffectView = [ initWithEffect:blurEffect];
visualEffectView.frame = _mapView.bounds;
;
//Hide Bars & Slider
;
[ setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
_toolBar.hidden = YES ;
_radiusSlider.hidden= YES;
_sliderIndicator.hidden = YES;
}
}
</code></pre>
<p>ModelViewController.m</p>
<pre><code>- (IBAction)dismisModal:(id)sender {
;
;
}
</code></pre>
<p>如何在关闭 modalView 的同时从 mapView 中删除模糊 SubView？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>这就是我设法让模态模糊工作的方法!</p>
<pre><code>let vc = UIViewController()
vc.view = UIVisualEffectView(effect: UIBlurEffect(style: .Light))
vc.modalPresentationStyle = .OverFullScreen
let nc = UINavigationController(rootViewController: vc)
nc.modalPresentationStyle = .OverFullScreen
presentViewController(nc, animated: true, completion: nil)
</code></pre>
<p>这里我在 prepareForSegue 上使用 .OverFullScreen 标志。在我的 viewControllers 上设置了一个模糊 UIVisualEffectView</p>
<pre><code>override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
if segue.identifier == "LifeEventSegue" {
if let nc = segue.destinationViewController as? UINavigationController {
nc.modalPresentationStyle = .OverFullScreen
if let vi = nc.viewControllers.first as? UIViewController {
vi.modalPresentationStyle = .OverFullScreen
}
}
}
}
</code></pre></p>
