私のアプリケーションでは、4 つの UIbuttons があります。同じアラート ビューを表示する各ボタンをクリックすると、学習と再生のオプションが含まれます。アラート ビューをクリックすると、uibutton の選択に応じて異なるビューを表示します。クリックオプションで別のビューを実行するのを手伝ってください。

-(IBAction)animals
{
UIAlertView *alert1=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];     
[alert1 show];
}
-(IBAction)birds
{
UIAlertView *alert2=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];
[alert2 show];    
}
-(IBAction)direct
{ 
UIAlertView *alert3=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];
[alert3 show];
}
-(IBAction)fruit
{
UIAlertView *alert4=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];
[alert4 show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];

if ([buttonTitle isEqualToString:@"LEARN"]) 
{


    animallearn *aview=[[animallearn alloc]initWithNibName:@"animallearn" bundle:nil];
    [self.navigationController pushViewController:aview animated:YES];
}
else if([buttonTitle isEqualToString:@"PLAY"])
{ 
    birdslearn *bview=[[birdslearn alloc]initWithNibName:@"birdslearn" bundle:nil];
    [self.navigationController pushViewController:bview animated:YES];
 }
else
{
    return;
}
}

UIAlertView のタグ属性があります。それはintです。タグに異なる値を割り当てる必要があります。

-(IBAction)direct
{ 
  UIAlertView *alert3=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];
  [alert3 setTag:3];
  [alert3 show];
}

そして、clickedButtonAtIndex デリゲート メソッドを使用すると、現在のアラート ビューのタグを確認する必要があります。

if(alertView.tag == 3) //etc ...

また、ARC を使用しているかどうかはわかりませんが、使用していない場合は、アラート ビューをインスタンス化するときに自動解放を追加する必要があります。

-(IBAction)animals
{
    UIAlertView *alert1=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];     
    alert1.tag = 1;  
    [alert1 show];
}
-(IBAction)birds

    UIAlertView *alert2=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];
    alert2.tag = 2;  
    [alert2 show];    
}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];

    if(alertView.tag == 1)
    {
            //animal alert
    }
    else if(alertView.tag == 2)
    {
            //birds alert
    }
    // and so on......

グローバルに宣言すると、次のようにデリゲートオブジェクトUIAlertViewと比較できます-UIAlertView

 UIAlertView *alert1;
 UIAlertView *alert2;

-(IBAction)animals
{
   alert1=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil];     
   [alert1 show];
}

-(IBAction)birds
{
    alert2=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"LEARN",@"PLAY",@"CANCEL",nil]; 
    [alert2 show];    
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
   if(alertView ==alert1)
  {
    if (buttonIndex==1)
    {

    }
    if(buttonIndex == 2)
    {

    }
 }    

if(alertView == alert2)
{
    if (buttonIndex==1) 
    {


    }
}

これによれば、タグは必要ありません:)単に条件を使用してください
