Question

I have a UITextField and suppose there are 5 characters in this textbox for e.g. hello.

Now I want to divide this word into single character i.e. ‘h’,’e’,’l’,’l’,’o’;

then how can I perform this kind of action.

Any help will be appreciated.

First get the string value from the textfield:

NSString *text = myTextField.text;

Then you can iterate each character:

NSUInteger len = [text length];
for (NSUInteger i = 0; i < len; i++)
{
    unichar c = [text characterAtIndex:i];
    // Do something with 'c'
}
