使用也非常简单：

/** 简转繁点击响应 */
- (IBAction)onSimpToTradAction:(UIButton *)sender {_resultLabel.text = [ZMChineseConvert convertSimplifiedToTraditional:_textField.text];
}/** 繁转简点击响应 */
- (IBAction)onTradToSimpAction:(UIButton *)sender {_resultLabel.text = [ZMChineseConvert convertTraditionalToSimplified:_textField.text];
}
