我在新的UIAlertController中意识到，我们无法适应任何自定义视图。我可以做什么这样做吗？

我的代码看起来很标准

let alertController = UIAlertController(Title: "My AlertController",message: "tryna show some images here man",preferredStyle: UIAlertControllerStyle.ActionSheet)        let okAction = UIAlertAction(Title: "oks",style: .Default) { (action: UIAlertAction) -> VoID in        alertController.dismissVIEwControllerAnimated(true,completion: nil)    }    let cancelAction = UIAlertAction(Title: "Screw it!",style: .Cancel) { (action: UIAlertAction) -> VoID in        alertController.dismissVIEwControllerAnimated(true,completion: nil)    }    alertController.addAction(okAction)    alertController.addAction(cancelAction)    self.presentVIEwController(alertController,animated: true,completion: nil)

UIAlertController扩展了UIVIEwController，它具有一个vIEw属性。您可以将该视图的子视图添加到您心中的愿望。唯一的麻烦是正确地调整警报控制器的大小。你可以做这样的事情，但是这可能会在下次苹果调整UIAlertController的设计时轻松破解。

Swift 3

let alertController = UIAlertController(Title: "\n\n\n\n\n\n",message: nil,preferredStyle: UIAlertControllerStyle.actionSheet)    let margin:CGfloat = 10.0    let rect = CGRect(x: margin,y: margin,wIDth: alertController.vIEw.bounds.size.wIDth - margin * 4.0,height: 120)    let customVIEw = UIVIEw(frame: rect)    customVIEw.backgroundcolor = .green    alertController.vIEw.addSubvIEw(customVIEw)    let somethingAction = UIAlertAction(Title: "Something",style: .default,handler: {(alert: UIAlertAction!) in print("something")})    let cancelAction = UIAlertAction(Title: "Cancel",style: .cancel,handler: {(alert: UIAlertAction!) in print("cancel")})    alertController.addAction(somethingAction)    alertController.addAction(cancelAction)    dispatchQueue.main.async {        self.present(alertController,completion:{})    }

迅速

let alertController = UIAlertController(Title: "\n\n\n\n\n\n",preferredStyle: UIAlertControllerStyle.actionSheet)let margin:CGfloat = 10.0let rect = CGRect(x: margin,height: 120)let customVIEw = UIVIEw(frame: rect)customVIEw.backgroundcolor = .greenalertController.vIEw.addSubvIEw(customVIEw)let somethingAction = UIAlertAction(Title: "Something",handler: {(alert: UIAlertAction!) in print("something")})let cancelAction = UIAlertAction(Title: "Cancel",handler: {(alert: UIAlertAction!) in print("cancel")})alertController.addAction(somethingAction)alertController.addAction(cancelAction)self.present(alertController,completion:{})

Objective-C的

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"\n\n\n\n\n\n" message:nil preferredStyle:UIAlertControllerStyleActionSheet];  CGfloat margin = 8.0F;  UIVIEw *customVIEw = [[UIVIEw alloc] initWithFrame:CGRectMake(margin,margin,alertController.vIEw.bounds.size.wIDth - margin * 4.0F,100.0F)];  customVIEw.backgroundcolor = [UIcolor greencolor];  [alertController.vIEw addSubvIEw:customVIEw];  UIAlertAction *somethingAction = [UIAlertAction actionWithTitle:@"Something" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {}];  UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {}];  [alertController addAction:somethingAction];  [alertController addAction:cancelAction];  [self presentVIEwController:alertController animated:YES completion:^{}];

话虽如此，一个不那么诡异的方法就是使你自己的视图子类与UIAlertController的UIAlertActionStyle布局类似。事实上，相同的代码在iOS 8和iOS 9中看起来略有不同。

iOS 8

iOS 9

iOS 10
