将字符串的每个单词中的第一个字符更改为大写

Question

I found the function below :

CFStringCapitalize

"Changes the first character in each word of a string to uppercase (if it is a lowercase alphabetical character)."

void CFStringCapitalize (
   CFMutableStringRef theString,
   CFLocaleRef locale
);

Does anyone know how to use it with my NSMutableString ?

Thank you,

Gauthier.

Answer 1

The capitalizedString method exists in NSString class, see the docs

NSString *foo = @"this is all lower";
NSString *fooUpper = [foo capitalizedString];

Note that this isn't iPhone specific, same code on the Mac.

Answer 2

(NSString *)capitalizedString

So:

NSString *myString,*myCapitalizedString;

myString = @"capitalize";
myCapitalizedString = [myString capitalizedString]; //produces a capitalized copy of 'myString'
