Swift

中文转拼音(带声调)

比如：

中国

->

zhōng guó

let base = "中国"
let mutableString = NSMutableString(string: base)
CFStringTransform(mutableString, nil, kCFStringTransformToLatin, false)
print(mutableString) // zhōng guó
           

中文转拼音(无声调)

比如：

中国

->

zhong guo

let base = "中国"
let mutableString = NSMutableString(string: base)
CFStringTransform(mutableString, nil, kCFStringTransformToLatin, false)
CFStringTransform(mutableString, nil, kCFStringTransformStripDiacritics, false)
print(mutableString) // zhong guo
           

中文提取首字母

比如：

中国

->

ZG

let base = "中国"
let mutableString = NSMutableString(string: base)
CFStringTransform(mutableString, nil, kCFStringTransformToLatin, false)

let pinyinArray = mutableString.components(separatedBy: " ")
let initials = pinyinArray.compactMap { String(format: "%c", $0.cString(using:.utf8)![0]) }
let firstCharJoin = initials.joined().uppercased()

print(firstCharJoin) // ZG
           

Objective-C

 CFStringTransform((__bridge CFMutableStringRef)mutableString, NULL, kCFStringTransformToLatin, NO);
 NSLog(@"%@", mutableString); // zhōng guó
