IOS 汉字转拼音

iOS在汉字转拼音中有系统中的方法  希望能帮到大家

- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.    //调用方法    NSString *pinYin = [self transformMandarinToLatin:@"南辕北辙"];    NSLog(@"%@",pinYin);    }

- (NSString*)transformMandarinToLatin:(NSString*)string{      NSMutableString *preString = [string mutableCopy];      /*转换成成带音调的拼音*/   CFStringTransform((CFMutableStringRef)preString,NULL,kCFStringTransformMandarinLatin,NO);      /*去掉音调*///    CFStringTransform((CFMutableStringRef)preString, NULL, kCFStringTransformStripDiacritics, NO);         returnpreString;}
