iphone : How to capitalize the first character of my textfield?

Question

In my iPhone app, I want to capitalize the first character in my UITextField's text.

How can it be done?

Answer 1

Simple:

NSString *text = [textField text];
NSString *capitalized = [[[text substringToIndex:1] uppercaseString] stringByAppendingString:[text substringFromIndex:1]];

NSLog(@"%@ uppercased is %@", text, capitalized); 

Answer 2

In Interface Builder (or IB integrated into Xcode 4), if you click on UITextField you can set the text and keyboard behaviour.
