Appending a string to a UITextField

How can I append a string by adding '.' onto a UITextField? I have tried this: [textfield.text stringByAppendingString:@"."]; but I am getting strange behavior - it converts the last character into a . instead of adding on. (I also use this code to add 0-9 chars and it works perfectly.)

Any other methods of appending the . and/or an explanations for this?

You need to do textfield.text = [textfield.text stringByAppendingString:@"."]; since the stringByAppendingString: returns a new string, it doesn't modify the existing one (as strings are immutable by default).

Try this:

textfield.text = [NSString stringWithFormat:@"%@.", textfield.text];
