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

In my iPhone app, I want to capitalize the first chara开发者_如何学Pythoncter in my UITextField's text.

How can it be done?

Simple:

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

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

---

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

---

NSString *capitalizedString = [textField.text capitalizedString];

here I'm giving a suggestion you try with is . I hope it will be helpful for you.

Go in xib, select textfield then in attribute inspector you got capitalization just select words option

---

If you have set up the text field in a nib file, select the nib you will see various 'Text Input Traits' in the Text Field Attributes - the first one in the list deals with capitalisation.

see rjstelling's answer.....

---

Set the Capitalization drop down under textfield attributes to Sentences.

Instead of tanking it separate and capitalizing, try this. Simple 1 line code.

NSString *text = [textField text];
NSString *capText = [text capitalizedString]; // capitalizes only first alphabet.
