Textfield to NSString

[aceiswild]

Hey guys so I have an alert prompt containing a TextField where a person can enter their name. Once they have entered their name and click okay I need there name to show up as a String in the interface. But i can't seem to get it right tho i have done something similar before. Here is is my code for the alert:

// ALERT WITH TEXT
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Your Name"
                                                    message:@"What is your name?\n\n"
                                                   delegate:self 
                                          cancelButtonTitle:@"Cancel"
                                          otherButtonTitles:@"OK", nil];
    alert.tag = kTag_EnterNameAlert;
    
    CGRect entryFieldRect = CGRectZero;
    if( UIDeviceOrientationIsPortrait( [UIApplication sharedApplication].statusBarOrientation ) ) {
        entryFieldRect = CGRectMake(12, 110, 260, 25);
    }
    else {
        entryFieldRect = CGRectMake(12, 72, 260, 25);
    }
    
    UITextField *nameEntryField = [[UITextField alloc] initWithFrame:entryFieldRect];
    nameEntryField.tag = kTag_NameEmtryField;
    nameEntryField.backgroundColor = [UIColor whiteColor];
    nameEntryField.keyboardType = UIKeyboardTypePhonePad;
    nameEntryField.keyboardAppearance = UIKeyboardAppearanceAlert;
    nameEntryField.autocorrectionType = UITextAutocorrectionTypeNo;
    nameEntryField.clearButtonMode = UITextFieldViewModeWhileEditing;
    nameEntryField.placeholder = @"Name Here";
    [alert addSubview:nameEntryField];
    [nameEntryField becomeFirstResponder];
    
    [alert show];
    
    
    // ALERT WITH TEXT


-(void)alert:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {
    
    if (buttonIndex == 1) {
        
       // NSString Code to write name to interface here
      nameEntryField.text = [NSString stringWithFormat:@"Name: %@"];
        
    }
    
}

Thanks for ideas.

Several issues here.
First, what you are doing in the clickedButtonAtIndex is setting the value in the alert textfield to null, which I think you don't want.

You should do something along the lines of:

NSString * someString = ((UITextField*)[alert viewWithTag:kTag_NameEmtryField]).text;

Also, when you format the string with %@ you should enter an argument, like:

[...] [NSString stringWithFormat:@"Name: %@", nameString];

Hope this helps.
Cheers.

your line: [NSString stringWithFormat:@"Name: %@"];

is missing the parameter.

also you have the line: if (buttonIndex == 1)

are you sure you are looking for 1 and not 0?

and finally, make sure you have the text field connected via interface manager.

Yes i have changed that 1 value to 0. But you can't connect an Alert with a textfield in the interface builder. Just have to change some things around and it should be good.

Thanks!
Apparently apple can reject your app if you have a textfield in an alert?
Has anybody had this happen?
