How to capitalize the first word of the sentence in Objective-C?

Question

I\'ve already found how to capitalize all words of the sentence, but not the first word only.

NSString *txt =@\"hi my friends!\"
[txt capitalizedString];
         


        

Answer 1

I know the question asks specifically for an Objective C answer, however here is a solution for Swift 2.0:

let txt = "hi my friends!"
var sentencecaseString = ""

for (index, character) in txt.characters.enumerate() {
    if 0 == index {
        sentencecaseString += String(character).uppercaseString
    } else {
        sentencecaseString.append(character)
    }
}

Or as an extension:

func sentencecaseString() -> String {
    var sentencecaseString = ""
    for (index, character) in self.characters.enumerate() {
        if 0 == index {
            sentencecaseString += String(character).uppercaseString
        } else {
            sentencecaseString.append(character)
        }
    }
    return sentencecaseString
}
