I got it!

You have to add these methods:

Preparation:

<UITextFieldDelegate> //import the Delegate protocol
- (void) presentSheet; //declare method in header file

Show the alert:

- (void) presentSheet { 	
	UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"New Alert" message:@"your message" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
	[myAlert addTextFieldWithValue:nil label:@"I'm the Placeholder"];
	
	[[myAlert textField] setDelegate:self];
	[[myAlert textField] setTextAlignment:UITextAlignmentCenter];
	[[myAlert textField] becomeFirstResponder];
	[myAlert show];
	[myAlert release];
	myAlert = nil;
}

Get clicked button and string:

- (void)alertView:(UIAlertView *)alertView 
clickedButtonAtIndex:(NSInteger)buttonIndex 
{ if ([alertView title] == @"New Alert") { //Only for one specific alert
	
	NSString *myString = [[alertView textField]text]; //Get the string
	NSLog(@"User Pressed Button %d and String is: %@", buttonIndex + 1, myString); //Put it on the debugger
	
	if ([[[alertView textField]text]length] <= 0 || buttonIndex ==0) 
		return; //If cancel or 0 length string the string doesn't matter
	
	if (buttonIndex == 1) {
		//Setup an object or do sth. else here
	}
}
}

Done button:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
	NSLog(@"Dismiss Return");
	[self alertView:(UIAlertView *)[textField  superview] clickedButtonAtIndex:1];
	[(UIAlertView *)[textField  superview] dismissWithClickedButtonIndex:1 animated:NO];
	
	return NO;
}
