UIAlertView 首先废弃了 IOS 9

我已经尝试了几种方法来使用 UIAlertController，而不是 UIAlertView。我尝试了几种方法，但我不能使警报行动工作。 Here is my code that works fine in IOS 8 and IOS 9 but is showing up with deprecated flags. I tried the elegant suggestion below but I can't make it function in this context. I need to submit my app and this is the last thing to address. Thank You for any further suggestions. I am a newbie.

#pragma mark - BUTTONS ================================
- (IBAction)showModesAction:(id)sender {
NSLog(@"iapMade: %d", iapMade3);


// IAP MADE ! ===========================================
if (!iapMade3) {


//start game here
gamePlaysCount++;
[[NSUserDefaults standardUserDefaults]setInteger:gamePlaysCount forKey:@"gamePlaysCount"];
NSLog(@"playsCount: %ld", (long)gamePlaysCount);


if (gamePlaysCount >= 4) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
message: THREE_PLAYS_LIMIT_MESSAGE
delegate:self
cancelButtonTitle:@"Yes, please"
otherButtonTitles:@"No, thanks", nil];
[alert show];


NSString *path = [[NSBundle mainBundle] pathForResource:@"cow" ofType:@"wav"];
_pop =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[_pop play];
[self dismissViewControllerAnimated:true completion:nil];


} else {
if (gamePlaysCount == 1)  {
// Create & store the next 5 mins when player gets 3 more lives
nextDateToPlay = [[NSDate date] dateByAddingTimeInterval:60*60*0.1];
NSLog(@"CURRENT DATE: %@", [NSDate date]);
NSLog(@"NEXT DAY: %@", nextDateToPlay);
[[NSUserDefaults standardUserDefaults]setObject: nextDateToPlay    forKey:@"nextDateToPlay"];
NSLog(@"nextDateToPlay: %@", nextDateToPlay);


UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
message:  THREE_PLAYS_LIMIT_MESSAGE2
delegate:self
cancelButtonTitle:@"Got it!"
otherButtonTitles:@"Start", nil];
[alert show];
} else {


if (gamePlaysCount == 3)  {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Basic"
message: THREE_PLAYS_LIMIT_MESSAGE3
delegate:self
cancelButtonTitle:@"Yep, I Know!"
otherButtonTitles:@"Start", nil];
[alert show];
}
}
}
}


}


// IAP NOT MADE =============================


#pragma mark - ALERTVIEW DELEGATE ============================


-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {


if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:@"Yes, please"]) {


UIStoryboard *storyboard = self.storyboard;
MenuViewController *svc = [storyboard instantiateViewControllerWithIdentifier:@"Store"];
svc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:svc animated:YES completion:nil];


}

从 iOS8苹果提供了新的 UIAlertController类，你可以使用它来代替 UIAlertView，它现在已经被弃用，它也在弃用信息中说明:

UIAlertView is deprecated. Use UIAlertController with a preferredStyle 改为 UIAlertControllerStyleAlert

所以你应该用这样的东西

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];
小开 
//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];
}

如果你想在 NSObject 类中使用这个警告，你应该这样使用:

-(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:^{
}];
});
}

新实施的快速版本是:

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

看看这个:

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];
-(void)Action


{


}

使用 UIAlertController 代替 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];
}

将 UIAlertController + AlertController 分类为:

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

在你的 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: 如果您想添加两个以上的按钮，然后添加另一个 对 UIAlertController 的更多 UIAlertAction。

我尝试了以上的方法，没有人能够显示警报视图，只有当我把 presentViewController:方法放在一个 dispatch_async句子:

分派 _ 异步(分派 _ get _ main _ queue () ，^ { [自我呈现 ViewController: 警报动画: YES 完成: 无] ; });

Refer to IOS9的 UIAlertView 替代品？.

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
}
}
小开 
 UIAlertController * alert = [UIAlertController
alertControllerWithTitle:@"Are you sure you want to logout?"
message:@""
preferredStyle:UIAlertControllerStyleAlert];

actionWithTitle:@"Logout"
style:UIAlertActionStyleDestructive
handler:^(UIAlertAction * action)
{


}];


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


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


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

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