是否可以通过iOS5中的另一个UIAlertView显示UIAlertView

我在password中获得第一个alertView，如果密码不正确，则另一个alertView显示密码不正确。现在第一个alertView消失。我想要在第一个alertView上显示第二个alertView。是否可以通过iOS5中的另一个UIAlertView显示UIAlertView

没你尝试过吗？ – sosborn

复杂的工作。 – Robin

当您解散第二个警报视图时，第一个警报视图将会回来。 –

这不是那么复杂的工作，我只是做了这样的： -

UITextField *forgetPass; 
-(IBAction)Password{// here is a Action for login password 
    //[txtEmail resignFirstResponder]; 


    UIAlertView* dialog = [[UIAlertView alloc] init]; 
    [dialog setDelegate:self]; 
    [dialog setTitle:@"Enter your password"]; 
    [dialog setMessage:@" "]; 
    [dialog addButtonWithTitle:@"Cancel"]; 
    [dialog addButtonWithTitle:@"OK"]; 
    dialog.tag= 1; 

    forgetPass = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; 
    forgetPass.delegate = self; 
    [forgetPass setSecureTextEntry:YES]; 

    forgetPass.placeholder = @"password"; 
    forgetPass.keyboardType = UIKeyboardTypeNumbersAndPunctuation; 
    [forgetPass setBackgroundColor:[UIColor whiteColor]]; 
    [dialog addSubview:forgetPass]; 
    CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0); 
    [dialog setTransform: moveUp]; 
    [dialog show]; 



} 



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

    if(alert.tag==1) 
    { 
    if (buttonIndex == 1) { // OK pushed 
     if([forgetPass.text length]>0) 
     { 

     } 
     else { 
      UIAlertView *alert2 = [[UIAlertView alloc]initWithTitle:@"Oops..!" message:@"please enter your current password" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
      UITextField *forgetPass2 = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; 
      forgetPass2.delegate = self; 
      [forgetPass2 setSecureTextEntry:YES]; 

      forgetPass2.placeholder = @"password"; 
      forgetPass2.keyboardType = UIKeyboardTypeNumbersAndPunctuation; 
      [forgetPass2 setBackgroundColor:[UIColor whiteColor]]; 
      [alert2 addSubview:forgetPass2]; 
      forgetPass2.hidden=YES; 
      CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0); 
      [alert2 setTransform: moveUp]; 


      alert2.tag=2; 
      [alert2 show]; 
      [alert2 release]; 

     } 
    } 
    if (buttonIndex == 0) 
    { 

    } 
    } 
    else if(alert.tag==2) 
    { 

     if (buttonIndex == 0) 
     { 
      [self Password]; 
     } 
    } 

}
