iOS-将中文转成拼音的方法

代码如下

- (void)viewDidLoad {
    [super viewDidLoad];
    
    NSString *chineseText = @"我爱编程";
    if ([chineseText length]) {
        NSMutableString *pinyinText = [[NSMutableString alloc] initWithString:chineseText];
        // 转换后拼音带声调
        if (CFStringTransform((__bridge CFMutableStringRef)pinyinText, 0, kCFStringTransformMandarinLatin, NO)) {
            NSLog(@"%@", pinyinText);
        }
        // 转换后拼音不带声调
        if (CFStringTransform((__bridge CFMutableStringRef)pinyinText, 0, kCFStringTransformStripDiacritics, NO)) {
            NSLog(@"%@", pinyinText);
        }
    }
}

运行结果如下
