我正在创建一个 iOS 应用程序，当分数达到 100 时，将显示此警报，并且一切正常，但按钮（分享、苹果、评价此应用程序）。
- (void) buttonAction {
counter++;
if(counter == 100)
[self showAlert];
}
- (void) showAlert {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:@"hello"
message:@"whats you name"
delegate:nil
cancelButtonTitle:@"Dismiss"
otherButtonTitles:@"share", @"apple" , @"rate this app", nil];
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0) { // means share button pressed
// write your code here to do whatever you want to do once the share button is pressed
}
if(buttonIndex == 1) { // means apple button pressed
// write your code here to do whatever you want to do once the apple button is pressed
}
// and so on for the last button
}
[alert show];

-(IBAction)plus {
counter=counter + 1;

and then add the following method in your code:
然后在您的代码中添加以下方法：
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0) { // means share button pressed
// write your code here to do whatever you want to do once the share button is pressed
}
if(buttonIndex == 1) { // means apple button pressed
// write your code here to do whatever you want to do once the apple button is pressed
}
// and so on for the last button

From your question I understand that, you need a method for identifying which alert button is pressed by the user. For that you can use this delegate method:
从您的问题我了解到，您需要一种方法来识别用户按下了哪个警报按钮。为此，您可以使用此委托方法：
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
}
Inside this method, you need to check the button index that was pressed by the user. And according to that, you can do the other stuffs.
在此方法中，您需要检查用户按下的按钮索引。据此，您可以做其他事情。
For using the delegate method, you need to set the delegateof alert view to self
要使用委托方法，您需要将delegate警报视图设置为self

You need to implement the UIAlertViewDelegatemethod: – alertView:didDismissWithButtonIndex:Set your controller as the UIAlertViewDelegate when you init it, then inside your implementation of – alertView:didDismissWithButtonIndex:, call the various methods pertaining to the relevant button index.
您需要实现UIAlertViewDelegate方法：– alertView:didDismissWithButtonIndex:在初始化时将控制器设置为 UIAlertViewDelegate，然后在您的实现中– alertView:didDismissWithButtonIndex:，调用与相关按钮索引相关的各种方法。
