UIAlertView首先不推荐使用IOS 9

108

我尝试了几种使用UIAlertController而不是UIAlertView的方法。我尝试了几种方法，但无法使警报措施起作用。这是我的代码，可以在IOS 8和IOS 9中正常工作，但是显示不推荐使用的标志。我在下面尝试了优雅的建议，但在这种情况下无法使其起作用。我需要提交我的应用程序，这是最后要解决的问题。感谢您提出任何其他建议。我是新手。

问题不清楚。你想要什么？
— Moucheg 2015年
在iOS 9中不推荐使用UIAlertView，而必须将UIAlertController与UIAlertControllerStyleAlert的preferredStyle一起使用。但是，当我使用UIAlertController方法时，警报不会显示。我尝试下面的解决方案，但仍警告视图不显示..谢谢你..
— 布克斯
好的。你能证明你做了什么，那是行不通的？

介绍完之后，您将调用[self dismissViewControllerAnimated：truecomplete：nil]; 这将关闭警报控制器

从UIAlertController相当新的意义上来说，这是一个重要的问题，许多开发人员将担心过时。不合理的否决票对有效问题不利。那些对这个问题投反对票的人应该在编辑后更改投票。但是随后，获得“否决票”徽章的“不赞成投票的巨魔”无论如何都不会这样做。SO主持人应该有一种解决方法。

从iOS8开始，Apple提供了新UIAlertController类，您可以使用它来代替现已弃用的UIAlertView，它也已在弃用消息中指出：

不推荐使用UIAlertView。改用UIAlertController和UIAlertControllerStyleAlert的preferredStyle

所以你应该使用这样的东西

UIAlertController * alert = [UIAlertController
                alertControllerWithTitle:@"Title"
                                 message:@"Message"
                          preferredStyle:UIAlertControllerStyleAlert];



UIAlertAction* yesButton = [UIAlertAction
                    actionWithTitle:@"Yes, please"
                              style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction * action) {
                                //Handle your yes please button action here
                            }];

UIAlertAction* noButton = [UIAlertAction
                        actionWithTitle:@"No, thanks"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   //Handle no, thanks button                
                                }];

[alert addAction:yesButton];
[alert addAction:noButton];

[self presentViewController:alert animated:YES completion:nil];

谢谢您的快速回复。.我尝试了此操作，但是没有显示警报视图。.当添加我的yes please操作时也没有显示。
— Bux 2015年
您能告诉我您的代码，因为它对我而言工作正常，请确保您在主线程上执行此代码
— Adnan Aftab
您可以在问题中添加代码，这样每个人都能看到更好吗
— Adnan Aftab 2015年
嗨，我添加了可在IOS8和IOS9中使用的完整代码，但已标记为不赞成使用。我尝试了几种方法来实现您的代码，但警报未显示，并且打开商店ViewController的操作将不起作用。谢谢您的帮助。
— 2015年
我认为最好[alert dismissViewControllerAnimated:YES completion:nil];从动作处理程序中删除此行，因为没有此代码，警报会自动隐藏。而且，可能会错误地将代码放入不会执行的完成块中。干杯：)

//Calling     
[self showMessage:@"There is no internet connection for this device"
                    withTitle:@"Error"];

//Method

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{

 UIAlertController * alert=   [UIAlertController
                                  alertControllerWithTitle:title
                                  message:message
                                  preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

        //do something when click button
    }];
    [alert addAction:okAction];
    UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    [vc presentViewController:alert animated:YES completion:nil];
}

如果要在NSObject类中使用此警报，则应使用以下方式：

-(void)showMessage:(NSString*)message withTitle:(NSString *)title{
dispatch_async(dispatch_get_main_queue(), ^{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    [alertController addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

    }]];

    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:^{
    }];
});

新实现的Swift版本是：

 let alert = UIAlertController(title: "Oops!", message:"your message", preferredStyle: .Alert)
 alert.addAction(UIAlertAction(title: "Okay.", style: .Default) { _ in })
 self.presentViewController(alert, animated: true){}

Xcode 8 + Swift

假设self是UIViewController：

func displayAlert() {
    let alert = UIAlertController(title: "Test",
                                  message: "I am a modal alert",
                                  preferredStyle: .alert)
    let defaultButton = UIAlertAction(title: "OK",
                                      style: .default) {(_) in
        // your defaultButton action goes here
    }
    
    alert.addAction(defaultButton)
    present(alert, animated: true) { 
        // completion goes here
    }

使UIAlertController + AlertController类别为：

UIAlertController + AlertController.h

typedef void (^UIAlertCompletionBlock) (UIAlertController *alertViewController, NSInteger buttonIndex);

@interface UIAlertController (AlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock;
@end

UIAlertController + AlertController.m

@implementation UIAlertController (NTAlertController)

+ (instancetype)showAlertIn:(UIViewController *)controller
                  WithTitle:(NSString *)title
                    message:(NSString *)message
          cancelButtonTitle:(NSString *)cancelButtonTitle
          otherButtonTitles:(NSString *)otherButtonTitle
                   tapBlock:(UIAlertCompletionBlock)tapBlock {

    UIAlertController *alertController = [self alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];

    if(cancelButtonTitle != nil) {

        UIAlertAction *cancelButton = [UIAlertAction
                                       actionWithTitle:cancelButtonTitle
                                       style:UIAlertActionStyleCancel
                                       handler:^(UIAlertAction *action)
                                       {
                                           tapBlock(alertController, ALERTACTION_CANCEL); // CANCEL BUTTON CALL BACK ACTION
                                       }];
        [alertController addAction:cancelButton];

    }

    if(otherButtonTitle != nil) {

        UIAlertAction *otherButton = [UIAlertAction
                                   actionWithTitle:otherButtonTitle
                                   style:UIAlertActionStyleDefault
                                   handler:^(UIAlertAction *action)
                                   {
                                       tapBlock(alertController, ALERTACTION_OTHER); // OTHER BUTTON CALL BACK ACTION
                                   }];

        [alertController addAction:otherButton];
    }

    [controller presentViewController:alertController animated:YES completion:nil];

    return alertController;
}

@end

在您的ViewController.m中

[UIAlertController showAlertIn:self WithTitle:@"" message:@"" cancelButtonTitle:@"Cancel" otherButtonTitles:@"Other" tapBlock:^(UIAlertController *alertController, NSInteger index){

 if(index == ALERTACTION_CANCEL){

 // CANCEL BUTTON ACTION
 }else
if(index == ALERTACTION_OTHER){

 // OTHER BUTTON ACTION
 }

 [alertController dismissViewControllerAnimated:YES completion:nil];

 }];

注意：如果要添加两个以上的按钮，则向UIAlertController添加另一个UIAlertAction。

使用UIAlertController而不是UIAlertView

-(void)showMessage:(NSString*)message withTitle:(NSString *)title
{
UIAlertController * alert=   [UIAlertController
                              alertControllerWithTitle:title
                              message:message
                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    //do something when click button
}];
[alert addAction:okAction];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
[vc presentViewController:alert animated:YES completion:nil];
}

我尝试了上述方法，只有将presentViewController:方法放在dispatch_async句子中时，没人能显示警报视图：

dispatch_async(dispatch_get_main_queue(), ^ { [self presentViewController:alert animated:YES completion:nil]; });

请参阅iOS 9的UIAlertView的替代方法？。

检查一下：

UIAlertController *alertctrl =[UIAlertController alertControllerWithTitle:@"choose Image" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *camera =[UIAlertAction actionWithTitle:@"camera" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self Action];  //call Action need to perform 
    }];

[alertctrl addAction:camera];
