Customized AlertView

In this post, we will learn, How to

1. Change the frame size of UIAlertView
2. Change the frame/Location of buttons on UIAlertView
3. Align the Title label of UIAlertView in center.

Check the method below in code  willPresentAlertView

And don't forget to write - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex  to handle the button click event of UIAlertview buttons.

- (void)willPresentAlertView:(UIAlertView *)alertView {

    

    

    if(alertView.tag==10)

    {

        //Set the frame size of Alertview

        alertView.frame = CGRectMake((1024-350)/2, (748-300)/2, 350, 200);

        

        //Align the title label

        UILabel *theTitle = [alertView valueForKey:@"_titleLabel"];

        theTitle.center=CGPointMake(170, 20);

        

        //Set the frame/location of buttons on alertview

        UIButton *cancelButton=[(NSMutableArray*)[alertView valueForKey:@"_buttons"] objectAtIndex:0];

        cancelButton.frame=CGRectMake(12, 125, 100, 45);

        

        UIButton *saveButton=[(NSMutableArray*)[alertView valueForKey:@"_buttons"] objectAtIndex:1];

        saveButton.frame=CGRectMake(124, 125, 100, 45);

        

        UIButton *laterButton=[(NSMutableArray*)[alertView valueForKey:@"_buttons"] objectAtIndex:2];

        laterButton.frame=CGRectMake(236, 125, 100, 45);

    }

    

}

-(void)showCustomizedAlertView

{

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Enter your Info" message:@"\n\n\n\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Save",@"Later" ,nil];

    alertView.tag=10;

    

    

    UILabel *labelA1=[[UILabel alloc]initWithFrame:CGRectMake(25,49,63,23)];

    [labelA1 setBackgroundColor:[UIColor clearColor]];

    [labelA1 setTextColor:[UIColor whiteColor]];

    [labelA1 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13]];

    [alertView addSubview:labelA1];

    

    UILabel *labelA2=[[UILabel alloc]initWithFrame:CGRectMake(25,85,63,23)];

    [labelA2 setBackgroundColor:[UIColor clearColor]];

    [labelA2 setTextColor:[UIColor whiteColor]];

    [labelA2 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13]];

    [alertView addSubview:labelA2];

    

    UILabel *labelA3=[[UILabel alloc]initWithFrame:CGRectMake(195,85,63,23)];

    [labelA3 setBackgroundColor:[UIColor clearColor]];

    [labelA3 setTextColor:[UIColor whiteColor]];

    [labelA3 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13]];

    [alertView addSubview:labelA3];

    

    

    UILabel *labelA4=[[UILabel alloc]initWithFrame:CGRectMake(195,49,63,23)];

    [labelA4 setBackgroundColor:[UIColor clearColor]];

    [labelA4 setTextColor:[UIColor whiteColor]];

    [labelA4 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:13]];

    [alertView addSubview:labelA4];

    

    

    

    [labelA1 setText:@"Name"];

    [labelA2 setText:@"Age"];

    [labelA3 setText:@"Sex"];

    [labelA4 setText:@"City"];

    

    [labelA1 release];

    [labelA2 release];

    [labelA3 release];

    [labelA4 release];

    

    //Add Them

    alertTextField = [[UITextField alloc] initWithFrame:CGRectMake(92, 50, 80, 25)];

alertTextField.borderStyle = UITextBorderStyleRoundedRect;

alertTextField.backgroundColor = [UIColor clearColor];

alertTextField.placeholder = @" ";

alertTextField.keyboardType = UIKeyboardTypeNumberPad;

    alertTextField.returnKeyType=UIReturnKeyDone;

[alertView addSubview:alertTextField];

[alertTextField becomeFirstResponder];

    

    

    alertTextField2 = [[UITextField alloc] initWithFrame:CGRectMake(92, 84, 80, 25)];

alertTextField2.borderStyle = UITextBorderStyleRoundedRect;

alertTextField2.backgroundColor = [UIColor clearColor];

alertTextField2.placeholder = @" ";

alertTextField2.keyboardType = UIKeyboardTypeNumberPad;

    alertTextField2.returnKeyType=UIReturnKeyDone;

[alertView addSubview:alertTextField2];

    

    

    

    alertTextField3 = [[UITextField alloc] initWithFrame:CGRectMake(245, 84, 80, 25)];

alertTextField3.borderStyle = UITextBorderStyleRoundedRect;

alertTextField3.backgroundColor = [UIColor clearColor];

alertTextField3.placeholder = @" ";

alertTextField3.keyboardType = UIKeyboardTypeNumberPad;

    alertTextField3.returnKeyType=UIReturnKeyDone;

[alertView addSubview:alertTextField3];

    

    

    

    alertTextField4 = [[UITextField alloc] initWithFrame:CGRectMake(245, 50, 80, 25)];

alertTextField4.borderStyle = UITextBorderStyleRoundedRect;

alertTextField4.backgroundColor = [UIColor clearColor];

alertTextField4.placeholder = @" ";

alertTextField4.keyboardType = UIKeyboardTypeNumberPad;

    alertTextField4.returnKeyType=UIReturnKeyDone;

[alertView addSubview:alertTextField4];

    

    

    [alertView show];

    [alertView release];

    

}

Output looks like following:
