Unicode码转换为汉字

转汉字

我觉得没什么用，但是也记着吧，万一有用呢

#pragma mark - Unicode编码转汉字
- (NSString *)replaceUnicode:(NSString *)unicodeStr {
    
    NSString *tempStr1 = [unicodeStr stringByReplacingOccurrencesOfString:@"\\u"withString:@"\\U"];
    NSString *tempStr2 = [tempStr1 stringByReplacingOccurrencesOfString:@"\""withString:@"\\\""];
    NSString *tempStr3 = [[@"\"" stringByAppendingString:tempStr2]stringByAppendingString:@"\""];
    NSData *tempData = [tempStr3 dataUsingEncoding:NSUTF8StringEncoding];
    NSString *resultStr = [NSPropertyListSerialization propertyListWithData:tempData options:NSPropertyListImmutable format:nil error: nil];
    
    return [resultStr stringByReplacingOccurrencesOfString:@"\\r\\n"withString:@"\n"];
    
}
