ios - 忽略以小写字母开头的 swift 字母

Question

这是我正在尝试做的事情:

let courseName = "Bachelor of Tourism Administration(B.T.A)".condensedWhitespace
let upperCaseCourseName = courseName.uppercaseString

let extrctCourseName = upperCaseCourseName.componentsSeparatedByString(" ").reduce("") { $0.0 + String($0.1.characters.first!) }

let upperCasecourseFirstCharcters = extrctCourseName

print(upperCasecourseFirstCharcters) // output : "BOTA" but i want "BTA"

如您所见，我的“Bachelor of Tourism Administration(B.T.A)”输出是BOTA，但所需输出是BTA，因为word of 是从小写字母开始的，我想在我的这个方法中忽略那个词，我该怎么做？

let courseName = "Bachelor of Tourism Administration(B.T.A)" //.condensedWhitespace
        var newString = ""
        let array : NSArray = courseName.componentsSeparatedByString(" ")
        for chr in array {
            let str = chr as! NSString
            if str.lowercaseString != str{
                if newString.characters.count > 0{
                    newString = newString.stringByAppendingString(" "+(str as String))
                    continue
                }
                newString = newString.stringByAppendingString((str as String))
            }
        }

        let upperCaseCourseName = newString.uppercaseString
        let extrctCourseName = upperCaseCourseName.componentsSeparatedByString(" ").reduce("") { $0.0 + String($0.1.characters.first!) }
        let upperCasecourseFirstCharcters = extrctCourseName
        print(upperCasecourseFirstCharcters)
