本文介绍了在iOS 6中呈现模态视图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我想显示模态视图,但我有两个问题:I want to display a modal view but I have two problems: iOS 6和I中没有presentModalViewController必须使用presentViewController,它只是显示我的第二个ViewController,如模态segue而不是没有全屏选项的模态窗口,There is no presentModalViewController in iOS 6 and I have to use presentViewController which is just display my second ViewController like a modal segue not a modal window without full screen option,我的第二个问题是如何显示UICollectionViewController的模态窗口。我尝试使用presentViewController,但它只适用于ViewController而不是CollectionViewController。My second problem is how can I show the modal window from UICollectionViewController. I tried to use presentViewController but it just works with ViewController not CollectionViewController.我想要做的最好的例子就是这个(Instagram)。他们是如何制作这个模态窗口的?是因为它仍然适用于较旧的iOS版本而且还不是iOS 6吗?或者还有另一种方法可以从UICollectionViewController中显示这样的模态窗口吗?The best example of what I want to do is this (Instagram). How they made this modal window? Is it because it's still working with older iOS versions and it's not iOS 6 yet? Or there is another way to display modal window like this from UICollectionViewController?谢谢推荐答案如果我理解你正在尝试实现的目的是在父级上呈现一个 ViewControllers 并仍然看到父 ViewController 在后台。If I understood you correctly what you are trying to achieve is to present one of your ViewControllers over the parent and still see the parent ViewController in the background. 第一个解决方案:UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"]; vc.view.backgroundColor = [UIColor clearColor]; self.navigationController.modalPresentationStyle = UIModalPresentationCurrentContext; //self.modalPresentationStyle might do a better job here [self presentViewController:vc animated:NO completion:nil];确保 SecondViewController 内容小于你当前的``ViewController`,你可以在StoryBoard \ xib中看到它的背景颜色。背景颜色将清晰,并将产生透明效果。Make sure your SecondViewController content is smaller than your current ``ViewController` and that you can see the background color of it in StoryBoard \ xib. The background color will be clear and will create the transparency effect. 第二个解决方案:创建一个容器(iOS 6及更高版本,如果您打算使用Storyboard IB,低于此将允许您创建容器,但只能创建容器)。Create a Container (iOS 6 and up if you are planning to use the Storyboard IB, lower than that will let you create Containers but only progrematicly).设置容器大小3/4父大小并将第二个viewcontroller连接到它。而不是将\推送到你的第二个视图控制器,你只需Set the container size 3/4 of the parent size and connect the second viewcontroller to it. Instead of segueing \ pushing to your second viewcontroller you can justmyContainer.alpha = 1;在屏幕上显示。 这篇关于在iOS 6中呈现模态视图的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
