import Foundation extension String { func transformToPinYin() -> String { let mutableString = NSMutableString(string: self) //把汉字转为拼音 CFStringTransform(mutableString, nil, kCFStringTransformToLatin, false) //去掉拼音的音标 //CFStringTransform(mutableString, nil, kCFStringTransformStripDiacritics, false) let string = String(mutableString) //去掉空格 //return string.stringByReplacingOccurrencesOfString(" ", withString: "") return string.replacingOccurrences(of: " ", with: "") } } |
print(“中国”.tranformToPinYin()) 输出 :
zhōngguó
