Question

I have this code to prompt the UIAlertView, with UITextfield:

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"New List Item", @"new_list_dialog")
                                                      message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
[myAlertView show];
[myAlertView release];

But I would like to add a get the textfield value, after the user click “OK”, and after the user click , I want to call a method, how can I assign that to the myAlertView? Thank you.

Answer 1

Declare the text field as global.And in the method of alertView clicked - (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex just take the value of the textfield and do the operations you want with it…..

Heres the revised code

UITextField *myTextField;
...
{

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"New List Item", @"new_list_dialog")
                                                      message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
[myAlertView show];
[myAlertView release];
}
....
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"string entered=%@",myTextField.text);
}

For iOS 5 and later
You can use alertViewStyle property of UIAlertView.
