UIAlertView first deprecated IOS 9
提问by Bux
I have tried several ways to use UIAlertController,instead of UIAlertView. I tried several ways but I cannot make the alert action work. 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.
我尝试了几种方法来使用 UIAlertController，而不是 UIAlertView。我尝试了几种方法，但无法使警报操作起作用。这是我的代码，它在 IOS 8 和 IOS 9 中运行良好，但显示了已弃用的标志。我尝试了下面的优雅建议，但我无法让它在这种情况下发挥作用。我需要提交我的应用程序，这是最后要解决的问题。感谢您的任何进一步建议。我是新手。

From iOS8 Apple provide new UIAlertControllerclass which you can use instead of UIAlertView which is now deprecated, it is also stated in deprecation message:
从 iOS8 Apple 提供了新UIAlertController类，您可以使用它来代替现在已弃用的 UIAlertView，它也在弃用消息中说明：
UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead
UIAlertView 已弃用。使用 UIAlertController 和首选样式 UIAlertControllerStyleAlert 代替
So you should use something like this
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];

//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];
}
If you want to use this alert in NSObject class you should use like:
如果你想在 NSObject 类中使用这个警报，你应该使用：
-(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:^{
}];
});
}

Swift version of new implementation is :
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){}

Assuming selfis a UIViewController:
假设self是一个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
}
}

Make UIAlertController+AlertController Category as:
使 UIAlertController+AlertController 类别为：
UIAlertController+AlertController.h
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
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
in your ViewController.m
在你的 ViewController.m
[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];
}];
NOTE: If you want to add more than two buttons then add another more UIAlertAction to the UIAlertController.
注意：如果你想添加两个以上的按钮，那么再向 UIAlertController 添加更多的 UIAlertAction。

I tried the above methods, and no one can show the alert view, only when I put the presentViewController:method in a dispatch_asyncsentence:
上面的方法我都试过了，没有人可以显示alert视图，只有当我把presentViewController:方法放在dispatch_async一句话中时：
dispatch_async(dispatch_get_main_queue(), ^ {
[self presentViewController:alert animated:YES completion:nil];
});
dispatch_async(dispatch_get_main_queue(), ^ {
[self presentViewController:alert animated:YES completion:nil];
});

使用 UIAlertController 代替 UIAlertView
-(void)showMessage:(NSString*)message withTitle:(NSString *)title

[alert addAction:okAction];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];

Check this:
检查这个：
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
{
}
