第一種薪介，獲取拼音首字母(傳入漢字字符串, 返回大寫拼音首字母)
- (NSString *)firstCharactor:(NSString *)aString
{
//轉(zhuǎn)成了可變字符串
NSMutableString *str = [NSMutableString stringWithString:aString];
//先轉(zhuǎn)換為帶聲調(diào)的拼音
CFStringTransform((CFMutableStringRef)str,NULL, kCFStringTransformMandarinLatin,NO);
//再轉(zhuǎn)換為不帶聲調(diào)的拼音
CFStringTransform((CFMutableStringRef)str,NULL, kCFStringTransformStripDiacritics,NO);
//轉(zhuǎn)化為大寫拼音
//? NSString *pinYin = [str capitalizedString];
//? ? //獲取并返回首字母
//? ? return [pinYin substringToIndex:1];
return str;
}
第二種扁凛，這里是用了copy,_ _bridge(C轉(zhuǎn)換為OC的一種方式)
+ (NSString *)transform:(NSString *)chinese
{
NSMutableString *pinyin = [chinese mutableCopy];
CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformMandarinLatin, NO);
CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformStripCombiningMarks, NO);
NSLog(@"%@", pinyin);
return [pinyin uppercaseString];
}
