Retrieve input text from a UIAlertView

Question

In Xcode 4.3 3, I created a button that generates a popup input box with (buttons Cancel & Enter), works ok, how do I retrieve the data entered and display it in a label or a table?

Here is how the code behind my button looks like.

- (IBAction)car:(UIButton *) sender NSString * title1 = [sender titleForState:UIControlStateNormal]; _mylabel.text = title1; UIAlertView *prompt = [[UIAlertView alloc] initWithTitle:@"Expense Amount in $:" message:@"\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Enter", nil]; _textField = [[UITextField alloc] initWithFrame:CGRectMake(12, 50, 260, 25)]; [_textField setBackgroundColor:[UIColor whiteColor]]; [_textField setPlaceholder:@"Amount"]; [prompt addSubview:_textField]; _textField.keyboardType = UIKeyboardTypeNumberPad; // show the dialog box [prompt show]; // set cursor and show keyboard [_textField becomeFirstResponder]; }

Thank you for your help.

As introduced in iOS 5, you should use the UIAlertViewStylePlainTextInput style. You will get your value right in the delegate methods. Don't use a custom textfield anymore.

What you are trying to solve here is a regular UITextField input data save, regardless of the alert view. You can accomplish that in different ways and with the use of the UITextField delegate methods:

textFieldDidChange textFieldDoneEditing textFieldShouldReturn

Just implement saving the input data in one of those methods, depends on the desired user experience.

Hey TommyG, Yes I'am trying to save the input data from a popup input box, not from a regular UITextField. Thx
